Mammograms tied to overdiagnosis of breast cancer

By Rachael Rettner

Up to a fourth of breast cancers found through mammograms are harmless and would not cause noticeable disease during the women's lifetimes, a new study from Norway suggests.

Such women are said to be overdiagnosed, because their cancers would not have caused symptoms or death. Overdiagnosis is a problem because women may receive tests and treatment they did not actually need.

However, researchers currently have no way of knowing which women have these cases; the study showed that it's statistically probable that such cases are occurring.

"These women are treated with all the harms of treatment, and without the benefit of it," said study researcher Mette Kalager, at the Telemark Hospital in Norway.

In the study, for every 2,500 women who underwent mammogram screening over a 10-year period, 20 cases of breast cancer were identified that would have caused significant disease if they went undetected, and one death was prevented. However, 6 to 10 cases of overdiagnosis occurred.

Women should be informed about the benefits and risks of breast cancer screening, including the risk of overdiagnosis, so they can decide if they want a mammogram.

"You have to weigh the benefits and the harms, and you have to make up your mind [about] what is most important for you," Kalager said.

Most guidelines recommend mammograms for older women, but there are differences about what age mammograms should start, and how frequently they should be done. The U.S. Preventive Services Task Force recommends women ages 50 to 74 receive a mammogram every two years, while the American Cancer Society recommends yearly mammograms beginning at age 40.

Any screening test that attempts to identify a disease early on will come with a risk of overdiagnosis. Previous studies have found that rates of overdiagnosis from mammograms vary, from 0 percent to 54 percent, Kalager said.

In the new study, Kalager and colleagues analyzed cases of invasive breast cancer that occurred in Norway between 1996 and 2005, a time period over which the country began a breast cancer screening program for women ages 50 to 69. Different regions of the country began the screening program at different times, and the researchers compared cases among women who had been offered screening with those not offered screening.

About 7,800 women were diagnosed with breast cancer during the 10-year study period. Of these, the researchers estimated between15 percent and 25 percent were overdiagnosed — in other words, between 1,169 and 1,948 women would never have faced illness due to their cancers.

Because screening is started earlier in the United States than in Norway, overdiagnosis probably occurs more often here, according to Dr. Joann Elmore, of the University of Washington School of Medicine in Seattle, and Dr. Suzanne Fletcher, of Harvard Medical School in Boston, who wrote an editorial accompanying the study.

But while a doctor might consider the diagnosis of a cancer that never causes symptoms or death to be overdiagnosis, from a patient's perspective, it might be exactly what they want "because they want control of their lives," said Dr. Leo Twiggs, a professor of obstetrics and gynecology at the University of Miami School of Medicine, who was not involved in the study.

A person who is diagnosed with pre-cancer might want to change their behavior, such as increasing the frequency of their mammograms, Twiggs said.

Overdiagnosis and overtreatment could be reduced if researchers had tools to distinguish between cancers that are likely to progress and those that are unlikely to cause any problems within a patient's lifetime, Kalager said. But currently, we don't have those tools, she said.

A "watch and wait" approach may also be a tough sell for anxious patients, or for radiologists who don't want to be sued if they miss signs of disease, Elmore and Fletcher said in the editorial.

"Nevertheless, unless serious efforts are made to reduce the frequency of overdiagnosis, the problem will probably increase," as new imaging techniques are introduced, they wrote.

The study and editorial are published in the April 3 issue of the Annals of Internal Medicine.

I'm not a physician but the idea of ignoring cancer, in any form, whether linked to breast cancer or prostate cancer seems absurd.

It may seem absurd until you understand the consequences of treatment for something that may not be life-threatening. Chemo, lumpectomy, or worse and all the side-effects for women. Possible impotence or incontinence for men not to mention a not-very-much-fun biopsy procedure for us guys with high PSA (I know, I have had one (negative and now they want me to do another)). It's not a trivial thing to understand what choice to make when the treatment can have a significant impact on your life and even the experts are divided on the best course of action.

But it isn't. Yes, it seems that way if you don't understand how cancers grow and how many times they grow very slowly over many, many years. A man with prostate cancer may live many years, but if he is treated aggressively immediately he may live the same number of years or less with some pretty nasty side effects from treatment. A woman who is diagnosed and treated immediately with aggressive treatment may live another 30 years, but with debilitating effects from treatment, disability, or end up with another cancer (and the first one) that may not have grown if she hadn't had the toxic treatments from the first one.

I'm not advocating ignoring cancer per se, but jumping on immediate aggressive toxic treatment just isn't always the best option. Radiation just isn't something you want to have unless it is a real necessity and neither is chemo, so the goal is to diagnose those cancers that truly would grow and kill or disable and treat them, but leave the ones that aren't going to make a person sick alone and not bombard them with radiation, surgeries, and chemicals that could be a catalyst for further growth. We just don't have all the answers, and it's hard to know the absolute best course of action sometimes. Ignore? Perhaps not. Become more judicious in diagnosis and treatment? Absolutely.

ram i can agree with what you said, however the other side of the coin is waiting till the cancer is a problem, which happened to a friend of ours, who really did not want to go thru the treatments if it was not necessary.

She waited too long and died. So your damed if you do and your damed if you dont. kMaybe on day they will find a treatment that is not so nasty.

and that is exactly why rising health care costs are difficult to curb...people want more care even if the diagnostic tool doesn't have much clinical utility. We need more funding for better, cheaper diagnostics that tell us information about the biology/biochemistry, rather than relying on all this fancy (and very, very expensive) medical technology. The -omics tests are the future!

    #1.4 - Mon Apr 2, 2012 9:43 PM EDT

    Ok, here is where I have to disagree. They do not specify which cancers they should ignore...they just state in this article that the study says mammograms overdiagnose cancers of the breast.

    They are saying to stop doing mammograms. Screening saves lives and is infinitely less expensive than treating a woman at age 55 with stage 3B or 4 cancer that could have been dealt with earlier, but because of mandates that state women need to wait until they are 50 it didn't get caught in time.

    I am willing to go through the risk of the biopsies, the risk of treatments in an early ductal in situ cancer removal, than to leave 3 children and a husband because some panel thought it was more cost effective to wait.

    Ductal in situ can be nothing or they can progress. Maybe look at the options of lumpectomy with more frequent mammograms after that instead of the oral chemos and radiation?

    I realize that other cancers kill women more than this..ie. lung cancers and certainly heart disease is the biggest threat to a woman's health overall, but the medical community at large is at fault for ramming this whole preventative medicine with mammograms early and often in the first place. You have entire generations of women who would revolt, regardless of research, at the thoughts of leaving any malignancy in their body.

    It should be a conversation that the healthcare provider and the patient have together. Not decided by a government or panel of people who have nothing to gain or lose by their suggestions.

    For what it is worth, a mammogram saved the life of 2 women I work with. They were both 32 at the time of diagnosis and had very aggressive tumors that no one expected them to have.

    If the so-called over-diagnosis saves the life of only one woman, it's worth it. Believe me, I was thrilled to know that the small lump in my breast was benign. How would I have known had they not checked it? And had it been malignant, at least they would have caught it early.

    I guess you don't understand what some of the treatments involve. The treatments can be as invasive as if the actual cancer were there. It is better to be sure that it is a real thing before you start treating it just for the sake of treating. I had a cousin tht had a colon caner screening. Some polyps were found and cut out. Two years later he was diagnosed with colon cancer and the site was everywhere thy cut the polyps. If they hadn't messed with them he would still be alive and cancer free today.

      #1.7 - Mon Apr 2, 2012 11:33 PM EDT

      f they hadn't messed with them he would still be alive and cancer free today.

      Utterly and completely false statement. I understand the need to find a reason for everything, and surely a temporal relationship seems like enough...until you stop and think about it...

        #1.8 - Tue Apr 3, 2012 12:08 AM EDT

        I agree with Eric. The polypectomy did not cause the cancer. If there was cancer present, it may have been missed but removing the polyp or "letting the air get to it" does not cause a cancer to spread nor does it cause cancer. There are non-polypoid colon cancers and they can be hard to diagnose early.

        The same goes for doing a biopsy of suspicious areas found on mammogram. In fact, biopsies of small lesions or suspected carcinoma in situ can now be accomplished with a needle and/or ultrasound or CT localization that does not leave a scar any bigger than a pinprick.

        There is a misconception in some of the statements concerning treatment also. No reputable radiation oncologist or medical oncologist is going to treat a person for a cancer that is not biopsy proven. A negative breast biopsy means no chemotherapy or radiation. As far as treating prostate cancer, that is more complicated. Everyone with early prostate cancer does not need treatment, but don't bet your life on it without discussing it with your oncologist or with more than one oncologist.

          #1.9 - Tue Apr 3, 2012 5:52 AM EDT

          It's because your understanding of the word cancer is a little off. There can be things that are "cancer" that do not spread and do not threaten your life.

            #1.10 - Tue Apr 3, 2012 9:02 AM EDT

            As a women who has had 4 lumpectomys, I can tell you that I am glad I had them removed. Maybe another women would opt to just watch them. I am not one of them. I think its a shame that the decision to choose what is right for ones own healthcare is dictated by these mandates and studies. Ultimately, it's the individuals RIGHT to choose what is best for THEM. And I would rather be safe than sorry. I have too much to live for.

            Based on the evidence presented, the issue isn't Mammograms, which are intended to detect anomalies that could lead to breast cancer. Mammograms save lives, because without them, there would be no way to detect cancer until after the person gets sick, which is often too late.

            No, the REAL issue that the article seems to point out, is the overzealous treatment of benign cysts without first making sure they really are cancerous.

            IMHO, this is yet another attempt to strip the public of vital health prevention programs, and in some circles, another attempt by ultra-conservatives to deprive women control over their own bodies.

                In the interest of fairness to both sexes, why isn't an equivalent amount of money spent on male health care under the age of 50? Or, if you don't give a crap about a lower male life-span, lower health insurance costs would allow more people to afford health insurance.

                There is more cancer and mortality data available and more experience with various preventative measures. What's wrong with channeling money spent on useless preventative health care into useful prevention?

                  I am in t6he middle of the same situation (only a hair worse) with prostate screening.

                  My "helpful" family physician decided, all on his own, that I needed to have PSA screens and did them for four years without consulting me. When one came up higher, he did the full PSA thing (free PSA, PSA velocity, etc) and ir came back much, much higher. He then referred me to a urologist "for a biopsy."

                  There was a federal blue ribbon task force set up to determine the risks/benefits of PSA screening. They determined that there was no benefit in survival to be had from PSA screening. Period. NO BENEFIT. They recommended that men under 40 not be screened unless they have already had treatment for prostate cancer. They recommended against screening for the remainder citing the lack of evidence that mortality or quality of life is improved by screening, biopsies, and aggreessive treatment. Their recommendation is that if a physician wants a patient to be screened, the physician should "fully inform him", a process that takes a minimum of 20-30 minutes.

                  It is a bad thing to do a procedure on someone without their consent and against current best practices. But it is even worse when you realize that a PSA test is invalidated if the patient had ejaculated within 72 hours (or 5-7 days if he has had a vascetomy.) Without knowing to do so, the physician has no way of knowing if he did. Moast PSA tests are inmvalid for this reason alone.

                  But I went to the urologist, who, in his best conversational manner, described the horrors of dieing from prostate cancer, used the phrase "just to be safe" exactly 11 times, and badmouthed the federal blue ribbon task force on mamograms (as a backhanded reference to the prostate panel) and described the biopsy as no-risk, easy, painless, and only minor inconveniences for side effects. He failed to mention that prostate biopsies are the second highest rate of re-hospitalization within 30 days, very high rates of infection, occasional permanent loss of sexual or uninary control forever, or that biopsies are being blamed for the conversion of many slow-growing to fast-growing cancers in a process called "needle trace tracking."

                  And even if you have the biopsy, you only have bad options --- you are going to eliminate a cancer with a one-in-twenty chance of killing me and senselessly run the risk of loss of quality of life. But at the cost of saddling 19-in-twenty with many of the same losses for no good reason.

                  There have been three major studies so far comparing various amounts of intervention between those with and those without aggressive testing, biopsies, and treatments. There was a slight difference between the groups in mortality from prostate cancer. But there was absolutely no diifference in overall mortality between the groups. So your choice ended up being whether you would have your heart attack playing beach volleyball or have it shopping for Depends.

                  This whole thing is a madness of unnecessary chaos and trauma in people's lives. And sometimes you just have to settle back and be the adult in the room and do the right thing. A lot of people make a lot of money from overdiagnosis and overtreatment and unnecessary screening associated with it. Those people have to be weeded out of medicine. But who's gonna do it?

                    The point of diagnostic tests is to identify areas of concern and then keep tabs on them so they don't become major problems in the future. You can't head off a problem if you don't know it's there. It seems we are being advised to close our eyes and stick our heads in the sand until our medical problems become so obvious they can no longer be ignored, at which point the medical community will tell us there is no point in treating the condition because it is too far advanced. A lot of people will suffer needlessly but it sure will save the insurance companies a lot of money.

                    they keep talking about 15 to 25% who may be overdiagnosed.

                    Hey.....what about the 75 to 85% who benefit from the diagnosis.

                    cutting down on screenings makes absolutely 0% sense to me.

                      the scientific community came out last year about the abuse of mammograms. Mostly for profit driven purposes as Hospitals and Clinics want to keep those machines paying the bills-so to speak-the AMA proceeded with an all out slander attack-obviously the rampant fleecing for profit associated with the "fear and panic" campaign the AMA has used on women to get mammograms for the last 30 years has gone even deeper than previously thought-imagine the unnecessary mutilation, horror and agony the AMA has inflicted upon women to line their pockets-seriously they need to change it from "Hippocratic Oath" to The Oath of Hypocrites-besides anyone with a brain should know that squishing breast cells to the point of rupturing while shooting them with radiation has to be a cancer risk in it's own-I think if you followed their advice and got your yearly from 35 and twice yearly after 50 that you would be sure to GET breast cancer by 70 if not sooner-I think that it might have been the plan from the start-more breast cancer the more money-besides the modern practice of medicine and surgery have victimized women since it's beginnings as part of the Catholic Church-which has always had an all out hate campaign against women from the witch hunts to the "No Birth Control" mandate and lovely devices such as the "pear" which ripped out a woman's uterus as torture -"modern" medicine has been a vicious and relentless enemy of women since it's conception and it was all about money then too!!-what ya afraid of boys??? that women hold not only the power of creation but that of healing as well?? it's a shame that out patriarchal society now pits women against each other by judging them solely on looks and youth-making our daughters think being strippers and whores are the only ways a woman can have "power" or respect-keeping us from uniting and always at odds at each other for the approval of men-and every time a man cheats with a skkankky ho-bag he just solidifies this attitude-it's areal manipulative power trip that has cost so many women their lives even

                          The term "over diagnose" is a misnomer and a dangerous one. Reducing "over diagnoses" here actually means not testing women as much, and therefore, reducing the rate of detection and subsequent diagnosis and treatment. Over diagnosis is generally used to indicate incorrect diagnosing of a condition - not the over treatment of a correct diagnosis as is being discussed here. The diagnosis here is not wrong - the treatment is being called incorrect.

                          So by naming the problem incorrectly, one makes the proposed solution more palatable; reduced testing. Really? Sticking your head in the sand cannot be the answer. Less testing will mean less diagnosis, but also more deaths from the ones who are not caught and have an aggressive form. Shouldn't the emphasis be placed on more education about types and treatments?

                          Do not reduce the rate of over diagnosis, increase the rates of appropriate treatments through education and funding.

                          For anyone who has had women they love die from breast cancer, going back to less testing cannot be acceptable.

The research is useful by keeping the researchers out of the way of patients and the doctors that treat them. Nice job, Mette Kalager, now get back to the lab before you do some real health damage.

                          So 75-85% had an "appropriate" diagnosis... those are great odds in reality especially when dealing with cancer.

                          Not only that, it is a rerun of an article done a year or more ago. It is also dangerous and irresponsible to write an article like this.

                          The Norwegian population is less genetically diverse than that of the U.S. Some subsets of women in the U.S. are far more likely to have aggressive forms of breast cancer than others. Young women in general and young Black women in particular are likely to have more deadly forms of breast cancer.

                          There are also published articles from U.S. studies that show that breast self-examination and exams by physicians are not enough. Mammograms have to be included as well to diagnose early breast cancers. It is very hard for a woman or a physician to feel a 1 cm. lump at the back of the central part of a breast, especially in a young woman with dense breast tissue or in any woman with fibrocystic changes.

                          This article is so irresponsible in its implications that I would consider it malpractice to use it as a reason not to do mammograms in the U.S.

                            It's just a statistical study that speaks of "probability". Nothing more, nothing less. However, some folks who are posting seem to see all kinds of evil in both sides of the equation. Everyone is different.

                            My Dad had colon cancer which was treated by surgery only. Radiation and chemo was recommended, but not really pushed by his physicians - he was basically given an opinion of, "We're pretty sure we got it all via surgery, but to be on the safe side, you should consider going through radiation and /or chemo.". He declined the additional treatments and died some years after of heart failure.

                            My Mom had lung cancer, for which a lung was removed. Same diagnosis and recommendation from her doctors as for my Dad. She died 18 months later after developing a brain tumor and subsequent spread to her other organs. She told me she didn't regret passing on the more invasive treatments - she did have Gamma Knife surgery on the brain tumor.

                            My point is, there are different results. But don't give up on using a diagnostic tool, such as the mammogram, colonoscopy, or PSA. It's just that individuals need to gauge and determine for themselves what their response is going to be to the test results, taking into account the best advice of a qualified physician.

                            Interesting article, but a little misleading. Right now 1 out of 7 women over age 50 will get breast cancer. That means that 14.2% of you are going to get it. Now if every one of you received a mammogram once a year, of those diagnosed with cancer, we would still lose 10% of you, due to tumors that are growing too fast. Additionally, only 10% of the breast cancers are genetic, the rest are diagnosed in women who have no family history at all. That means that some of you are going to be very surprised about being diagnosed with cancer. So, what will be it be ladies - will you take the chance? Many say no, and get their yearly mammograms despite all the experts. Cancer is a terrible thing to have, but breast cancer survival rates are excellent now, and the chance of getting it again after you are treated is only 6%. Just think, breast cancer survivors have a less chance of getting cancer again - 6%, then the woman standing next to her being newly diagnosed - 14%. We have come a long way in survival rate with this terrible disease.

                              Not a problem....when your daughter or wife is told they have an abnormal mammogram....just sit on it and see what happens. Sure don't want to be "over diagnosised". Be happy that research is being done and that people are acting on the best information that we have available today and be looking forward to the day when we cure this disease.

                              Believe it or not....doctors truly care about our patients and pain with their suffering. That is what we do.

                              My Father died from chemotherapy. Yes, he would have eventually died from the leukemia, but not nearly as fast as the poison they treated him with. He died five weeks after he was diagnosed and it was from the effects of the chemo. Had his doctors been honest with him, they would have told him the mortality rate for someone his age going through the chemo was almost 95%. The leukemia would have killed him in about 4 months, however, the chemo left him wishing for death. He died a horrible death and he should have been given every bit of information available so HE could make an informed choice.

                              Sorry about your father. I'm sure he would have preferred riding off a cliff in a glorious fiery chariot, but instead he was tortured in a hospital away from everything he enjoyed.

                              An excessive portion of health care costs are for costly near-end of life procedures. These need a re-evaluation in favor of spending money for superior care during other periods of life or an overall reduction in health insurance costs to allow more people access to medical care.

                                Over-diagnosed. Not totally sure how to apply this and therein lies the problem. I would guess then that this term could also be applied to colonscopy where polyps are removed either during the procedure or with surgery because they MAY become malignant.

                                I'm not buying this. Like susi-oh, I had a benign breat tumor, and I am grateful because I was not denied a mammogram to find this out. No rationed health care please!

                                Kudos for a brave article. The truth is, the cancer industry is literally scaring women to death. It's hard to accept the idea that some breast cancers may actually resolve on their own WITHOUT treatment. It's not about ignoring a deadly disease, it's about letting women know they're being scammed by a money making machine, and dying from treatment rather than disease. We've been victims for too long.

                                  It's Okay - it's the good kind of CANCER - it won't hurt you. This is the most ridiculous thing I've heard in a long time. Sounds to me like they can now find the cancer and it's getting to expensive for the insurance companies to treat! You try to look into the eyes of a woman with breast cancer and tell her she has cancer but it's okay, we don't think it will kill you. What cancer is next on the 'do not treat list'? Talk about death panels!

                                  This article is insane. I was diagnosed with breast cancer last year that the mammogram did not pick up but an ultrasound did. Although I was stage I, a new gene study showed the lesions to be "high risk for reoccurence", hence my decision to have mastectomies and chemo. That study did not take this gene test into account.

                                  I agree that overdiagnosis is a problem. Just read 2 excellent books by Dr. Gilbert Welch ("Should I Be Tested for Cancer: Maybe Not and Here's Why" and "Overdiagnosed") or also books by Dr. Nortin Hadler ("The Last Well Person" and "Worried Sick"). We have become a society of "worried well" and a lot of that is because of the constant barage of messages we get from the medical profession, advocacy groups and other groups with vested interests (in screening technology, pathology, etc.) which scares a lot of people. After all, we do have a for profit medical industry. A lot of it is money driven. The biggest problem I see is that people are not given all the information on the risks and benefits of screening tests. They are just sold to everyone with (sometimes) slanted statistical information. People also buy into them because of others' testemonials: early screening "saved" my life. Trouble is that lots of times cancers that were found never would have progressed and/or caused death whereas an aggressive cancer may turn up between screenings. Another misleading statistic that is quoted is the five year survival rate. If a cancer is found early, the five year survival rate is better than if it is found late. However, if a cancer is found early that person still may die within 7 years (they had a better 5 year survival rate) but that same cancer, diagnosed in someone once symptoms presented, may have only lived 2 years (thus had a poor 5 year survival rate). But both individuals died at the same time: the one who was diagnosed early just knew they had cancer longer.

                                  I agree with usa2011, also. The removal of colon polyps is in theory supposed to reduce the risk of colon cancer, which may be true. The problem I have with that is, again, little if any information is given to the patient about the true nature of polyps. If you research it you will find that the vast majority of polyps, especially the small, tubular adenomas (which are most commonly found) do not progress to cancer. Google "Hype Alert: Dr. Oz's Colonoscopy" or "Questioning Colonoscopy Evidence" from Gary Schwitzer's Health News Review blog. When you read most information about colonoscopies (mostly from gastro doctors) they make it sound like EVERY polyp will turn into cancer if it is left in the colon. This is just not true. If people were given the true facts about a lot of these screening tests they may choose to take the small risk of developing the disease versus having to get on the merry-go-round of constant medical surveillence. After all, cancer screening is optional, not mandatory, and I think a lot of people have been oversold on its benefits. We are, indeed, a society of "worried well". Not for me, thank you. I prefer to live life well and enjoy my good health without constant checking by a doctor to find something wrong with me. I will save doctors visits for when I truly need them.

                                    Between my insurance refusing to cover a follow-up ultrasound (at all, not even 80/20), and research like this, I am opting out of mammograms. And I have a family history. This is getting more and more questionable, particularly the potential side effects of the test after years and years of it, that may actually cause or make a small cancer that otherwise would resolve to flare and actually threaten me. I think in 10 years we will look back on the crazy old days where women spent so much money on these annual breast x-rays.

                                    Couldn't agree more! The incidence of one particular type of breast cancer has increased by 328% since mammograms went into widespread use. Radiation and compression are NOT good for breast tissue.

                                      Umm...isn't a biopsy the next step after a problem mammogram? Doesn't the biopsy show the aggressiveness of the cancer? Why would anyone decide their treatment without close examination of the tissue?

                                        Because the science is very imperfect. We don't currently have a compete understanding of which cancers need to be treated and which will not be harmful if left alone. So lots of women are left believing that they "would have died if they didn't have a mammogram" when, in fact, for a significant percentage of these women, that is totally untrue. But doctors don't always know which cancers to treat and which to leave alone, and no doctor is going to tell somebody not to worry because they don't want to be sued. And what woman, having been through a painful and exhausting cancer treatment, wants to believe that it was all unnecessary? She will consider her treatment successful, not knowing it could have been successful because that particular cancer would not have progressed or caused harm.

                                        However, researchers currently have no way of knowing which women have these cases; the study showed that it's statistically probable that such cases are occurring.

                                        So, we don't know which cases are the "overdiagnosis", but we just know that statistically, they occur... Hmmm.... so logically, its better if we DON'T stop "overdiagnosis" because statistically, women who do have the life threatening illness will suffer more than not. Tough call, science. Tough call.

                                        Also, 50% of statistics are made up, anyway.

                                          Subjecting the tender tissue of the breast to compression and radiation is absurd! How many cancers were actually caused by the use of mammograms? We may never know. Relatively speaking, mammograms are cheaper than MRI diagnostics, so that's why mammograms are the diagnostic tool of choice. Cheaper...definitely not more effective. Women need to start demanding a choice in diagnostics. Until then, NO ONE better try putting my girls in a vice and shooting them full of radiation. No thanks!

                                          Call me crazy but: Find a tumour, take it out. I had a Malignant brain tumour removed 16 months ago BUT due to the size of the tumour itself I was told it had been present for more than 10 yrs and I had no symptoms until 16 months ago when I started having seizures. Now that the tumour is removed I'm not doing chemo or radiation but rather observation to assure no regrowth which is alot better for someone to "watch" it than to attack it with chemo or radiation. As others have stated, if you leave a Malignant tumour in your body to stew it could just get to worse and eventually be too late. I'm thankful my tumour presented symptoms when it did or else it could have been alot worse.

                                            The absolutely humiliating and horrifying experiences I had when told I had breast cancer was enough to swear me off allopathic medication for good. The fearmongering was the worst--and let's face it, we all die from something and not everyone gets to live to age 100! In my mind it was always all about the money, how much could they push me to do, necessary or not, and no one ever gave any time to my questions about the downside of the treatment. Is this right for everyone? Of course not--but I do object to the questionable antics of so-called health care providers.

                                                When it comes to cancer there's no guarantee. Not with treatment, blood works, scans,and certainly not with mammograms. I know several friends who have had false positives over the years. One whose mother was told she almost assuredly had breast cancer, only to find out after biopsy that it was benign. I belong to a cancer survivors network (having lost my mother to uterine cancer, a BIl to esoph. cancer and a dear friend that just completed treatment for breast cancer) You can have a mammogram, get an all clear, and 6 mos later be diag. with breast cancer. There's about 5 or 6 different types of BC and some of them are very aggressive. I also know someone whose film was misread, was told everything was fine and did indeed have BC. I'm no telling anyone to have or have not the test, just do your research, be vigilant and always get a second opinion. Nothing replaces examining your own breasts every month and looking in mirror for changes in size, shape, appearance.
