Compared to those who have never used it, young people who use indoor tanning have a 69% higher risk of developing a type of skin cancer called basal cell carcinoma (BCC), according to a new study led by researchers from the Yale School of Public Health in the US that was published online on 12 December in the Journal of the American Academy of Dermatology.
The researchers found the risk was strongest among women and went up with every year of using indoor tanning.
A number of studies published recently shows an increase in people, particularly young women, with BCC. The researchers in this study concluded that a quarter of cases of early-onset BCC could be prevented, and as many as 43% among women, if people never used indoor tanning at all.
Senior author Susan T Mayne, professor at the School of Public Health, told the press:
"Indoor tanning was strikingly common in our study of young skin cancer patients, especially in the women, which may partially explain why 70 percent of early-onset BCCs occur in females."
Mayne said they were also "surprised to find that one-third of our study participants with BCC had already had at least one additional BCC before age 40, which is very alarming as skin cancers increase in frequency with age".
BCC is the most common type of skin cancer, it rarely spreads or kills, but it can invade surrounding tissue and cause unsightly disfigurement. Most occur on parts of the body that are repeatedly exposed to the sun, such as the head and neck, but there appears to be an increase in cases of them appearing on the torso.
For the study, Mayne and colleagues interviewed 376 patients diagnosed with BCC and 390 controls without BCC who had been diagnosed with minor, benign, skin conditions. All subjects were under 40 years of age. They answered questions about whether they had ever used indoor tanning, and if so, at what age they started, how often they used it, how long did sessions last, the number of burns received as a result of tanning, and the type of tanning machine.
Using statistical tools, they then calculated the odds of developing BCC, using those who had never used indoor tanning machines as the referent group.
The analysis showed that: Ever using an indoor tanning machine was linked to a 69% higher risk of early-onset BCC.
This link was stronger among young women, for those who developed more than one BCC, and for those whose BCCs appeared on the torso or extremities.
The risk went up in a "dose-dependent" fashion for each of three variables: each year of using indoor tanning, number of overall burns, and burns to biopsy site.
27% of early-onset BCCs, and as many as 43% in women, could be prevented if individuals never used indoor tanning machines.The researchers conclude:
"Indoor tanning was a strong risk factor for early-onset BCC, particularly among females. Indoor tanning should continue to be targeted by both policy-based and behavioral interventions, as the impact on BCC-associated morbidity may be substantial."
They say due to some of the study limitations, such as "potential recall bias of indoor tanning by patients and generalizability of the control population", the results need to be confirmed by further research.
Should these findings be confirmed, they add to recent evidence that indoor tanning is linked to melanoma, a less common but much deadlier form of skin cancer that is also increasing among young women.
First author Leah M. Ferrucci, a postdoctoral fellow at the School of Public Health, said:
"Importantly, indoor tanning is a behavior that individuals can change. In conjunction with the findings on melanoma, our results for BCC indicate that reducing indoor tanning could translate to a meaningful reduction in the incidence of these two types of skin cancer."
Estimates suggest around 30 million Americans use indoor tanning beds every year, with young women being the most common users.

It is possible to "prove" anything with statistics.
In the case of tanning bed use, it is important not to burn the skin.
Still, and according to real experts on tanning and vitamin D, it is 10 to 30 times more dangerous for health not to tan regularly than the, easily negotiable, risk of tanning too much.
Why was not the statistic of BCC among people who used tanning beds but never burned themselves, reported?
Probably it was not enough scaring, if measured at all.

Orangutans shed light on obesity in people
CHICAGO (Reuters) - In lush times, orangutans on the island of Borneo gorge themselves on forest fruits, packing on extra pounds in preparation for leaner years, when they live off leaves and bark and their own stored fat.
This behavior of overeating is all too common in humans, but rarely seen in nonhuman primates, and studying it may offer some clues about obesity and eating disorders in people, U.S. researchers said on Tuesday.
"Orangutans make very interesting models for studying human obesity because they are really the only apes and potentially the only nonhuman primates in the wild that actually store fat deposits," said Erin Vogel, an evolutionary anthropologist from Rutgers University in New Jersey, whose study appears in the journal Biology Letters.
"It's never been documented in any other species," Vogel said in a telephone interview.
Vogel and colleagues studied urine samples from Bornean orangutans laboriously collected over a period of five years by a team led Dr. Cheryl Knott, a biological anthropologist at Boston University.
"Orangutans living in this really challenging habitat are able to take advantage of these periods of incredible fruit abundance -- these masting periods, where 80 percent of the fruit on the trees are fruiting," Vogel said.
"They eat and eat and eat and they get fat," she said.
Then they go through periods of very low fruit production that can last up to eight years.
In the study, as food stores became more and more scarce, the orangutans shifted to bark and tough leaves to survive. And the team noticed changes in the apes' urine.
First, they saw ketones, a sign that the body was metabolizing fat. "It indicates they are burning this fat for energy," Vogel said.
And then they saw elevated nitrogen isotopes. These indicated that muscle cells were being broken down to obtain protein and energy.
"They have to get energy from somewhere, so they start to digest their body tissue, just like you would find in situations were humans are very impoverished, and in anorexia, where we would potentially see conditions where humans would digest their own muscles," Vogel said.
Vogel credits Knott's team for collecting the urine samples, which was no mean feat.
The team followed the orangutans from the time they woke up in their nest until the time they went to sleep.
"As soon as they wake up, they typically void -- they urinate," Vogel said.
Knott's team would be waiting underneath the tree canopy to collect these samples, either with plastic sheeting or an inverted umbrella held over their heads, which worked as both a collection device and some protection from the shower of urine.
Vogel said the study shows how orangutans have taken advantage of their ability to store fat to increase their chances of survival, but this same ability is a deficit for most humans who do not need to forage for food.
"We have this wonderful ability to store fat, and now most of us wish we didn't have it," she said.
In future studies, Vogel said she plans to look for fluctuations in the hunger-related hormones ghrelin and leptin during periods of food scarcity and abundance, as well as changes in inflammatory cell signaling chemicals known as cytokines, which are thought to play a role in obesity.
Orangutans are endangered. There are only 50,000 individuals remaining in Borneo and 7,300 in Sumatra -- the two places in the world where they can still be found in the wild.
