Indoor tanning when young increases skin cancer risk

With beach trips and swimming expeditions planned, teens and young people may be tempted to turn to indoor tanning beds to even out their summer color.
But Dartmouth researchers have found that early exposure to the ultraviolet radiation lamps used for indoor tanning is related to an increased risk of developing basal cell carcinomas at a young age, according to a study released June 23. The research calls attention to the importance of counseling young people about the risk of indoor tanning.
“Our findings suggest that teens and young adults who seek indoor tanning may be especially vulnerable to developing basal cell carcinomas, the most common form of skin cancer, at a young age,” said lead author Professor Margaret Karagas, co-director of the Cancer Epidemiology and Chemoprevention Research Program at the Norris Cotton Cancer Center and Director of the Children’s Environmental Health and Disease Prevention Research Center at Dartmouth. “But a recent survey in New Hampshire, where our study was conducted, found that 74 percent of high schools have at least one tanning salon within 2 miles, and an additional 22 percent have easy access to a tanning salon. We need to help young people understand these risks.”
The researchers collected data on 657 participants (all under 50) who had newly diagnosed cases of basal cell carcinomas and 452 controls. The data they collected included the type of indoor tanning device used (sunlamps, tanning beds or booths), and skin sensitivity to the sun and proportion of time spent outdoors in childhood.
A higher proportion of patients with early-onset basal cell carcinomas reported indoor tanning with a tanning lamp compared to controls, and this association was present for all types of indoor tanning devices. The researchers also found that participants with early-onset basal cell carcinoma were more likely to burn rather than tan during the first hour of sun exposure in summer as compared to controls. In about 40 percent of cases, basal cell carcinomas were located on the torso (and sites other than the head and neck) and the association with indoor tanning was stronger for tumors occurring in these places.
The study notes that indoor tanning products can produce 10 to 15 times as much UV radiation as the midday sun, and supports the recommendation of medical groups, including the American Academy of Pediatrics, to minimize ultraviolet exposure, including from indoor tanning.

    I am writing in response to Mr. Hoxworth’s article on transportation costs for the poor in Vermont. I would like to suggest further research on this topic before we simply just give another handout or tax credit. The poor, may, have a higher disproportionate burden on their transportation costs than the wealthier residents of Vermont; however, they also have a lower disproportionate burden on taxes and housing. Pick your evil.
    We can simply just give every poor Vermonter an energy efficient car, gas card, free tuition, renter’s rebate, etc.…but the only way out of poverty is through the combination of education, hard work, and discipline. Education and degrees are not handed out or purchased; a person has to EARN them. This seems to be the only way out of poverty—sorry, there are no shortcuts.
    If we continue this trend of enabling, our entire state will be a welfare state.
