Nail salon lamps don't raise skin cancer risk, study finds

While the risk of developing skin cancer is known to be linked with exposure to ultraviolet light, it's been less clear whether the UV lamps used in nail salons might raise the risk of skin cancer. Now, a new study suggests these lamps don't increase skin cancer risk.

In the study, researchers looked at three commonly used UV nail lamps. They measured the light, in terms of its likely carcinogenic effects, and calculated the "UV dose" that a user would receive during a 10-minute nail-drying session.

Not all ultraviolet lamps are the same — for example, people with the skin condition psoriasis may be treated with lamps, and studies have shown these "narrowband UVB" treatments raise the risk of skin cancer only minimally, compared with the more damaging rays of tanning salon lamps.

The new study showed that between 13,000 and 40,000 nail-drying sessions would be needed before a person would receive the same UV dose as a person with psoriasis who received light treatments for their condition, according to researchers Dr. Alina Markova, of the Massachusetts General Hospital in Boston, and Dr. Martin Weinstock, of Brown University. 

That's about 250 years of weekly manicures.

The findings mean that using these UV lamps "does not produce a clinically significant increased risk of developing skin cancer," the researchers wrote.

Two previous studies have looked at this question, the researchers said. In a 2009 report, researchers concluded that UV nail lamps were a risk factor in the cases of two women who developed skin cancer known as squamous cell carcinomas on the backs of their hands. In the other study, a laboratory hired by the nail salon industry tested many UV nail lamps and concluded UV light levels emitted were low and safe.

However, researchers of the new study noted that report about the two women was anecdotal, and did not include measurements of the UV light from the lamps. They also said the methods used in the industry-funded study were inappropriate.

"Dermatologists and primary-care physicians may reassure patients regarding the safety of these devices," the researchers wrote in their article, published Thursday (Dec. 6) in the Journal of Investigative Dermatology.

The lamps may not pose a problem, but do you really know what the chemicals in nail polish will do to your body?

    Was this really a concern? I mean, you have your fingertips under a UV lamp for like 30 seconds every 2-3 weeks. You get more UV exposure walking from your car to the salon. Can we all just stop panicking about UV rays. It is sunshine, people. We need it to survive.

      forget about the lamps, the noxious fumes will kill you. I get my hair cut at a place that has a nail salon attached.. I can smell the fumes from the polish on the other side of building.. it's sickening.

        The lamps are more dangerous to your eyes than to the skin by a good bit - especially the monochromatic LED curing systems used for gel nails. Don't look into the light and you're gonna be fine.

        The ones that dry regular nail polish are garden variety 40W black light tubes - totally harmless save for the usual "blue light hazard" - which has been tied to AMD and other visual problems.

        As someone pointed out - the acrylic monomer and acetone are a far bigger risk. Asian nail salon workers will be the new cancer cluster.

        Then again - I do recreationally abuse solvents and work with unshielded nuclear sources so I'll probably get cancer too.

        I recommend purchasing stock in MDS Nordion and Varian Medical systems. They both make cancer fighting solutions. I already have :D
