Don't fall for media scare tactics.

The Indoor Tanning Association will not stand by and allow some members of the media to unfairly malign our product and the thousands of small business owners who are our members, by grossly exaggerating the risks associated with tanning beds. Because tanning beds produce the same UV light as the sun, OVEREXPOSURE and abuse of our product—just like OVEREXPOSURE to sunlight—is associated with an increased risk for some types of skin cancer. Other items in this category are red wine and salted fish. According to IARC’s report on alcohol, drinking red wine or other alcoholic beverages carries a greater cancer risk than tanning. It is completely irresponsible to compare indoor tanning with mustard gas or arsenic as so many media reports today have done.


·
Tanning beds have been categorized as “Group 1” by a group of scientists in France. “Group 1” means there is evidence that the use of tanning beds can increase the risk of skin cancer.



·
The information is not very new: sunlight is in the same category as tanning beds, and has been in that category since 1992. Just like sunlight, the light from tanning beds has UV rays that cause your skin to produce melanin.



·
Since 1992, thousands of doctors have recommended moderate exposure to sunlight for a variety of health benefits. Oprah guest Dr. Oz Mehmet and Dr. Andrew Weil are two prominent examples.



·
Being in the “Group 1” category does not say anything about the size of the risk, just that there is any risk at all. Some things in the category are very dangerous, like arsenic and mustard gas. Other substances only carry a very small risk, like red wine, beer, and salted fish.



·
News stories that say things like “tanning is as dangerous as arsenic” are flat-out wrong. The scientists have not made that kind of comparison at all, only reporters looking for a scary headline.



·
The report itself has not been made available. All the news stories are working off of a press release, and no reporters have actually read the report.



·
The IARC is a group of scientists that works with the United Nations. Their report is not a new study; it is a review of a paper from 2006, which itself was a review of 23 studies, some dating to the early 1980s. Those studies had a wide range of findings.



· Of the 23 studies:

-
5 were excluded for unusable data

-
6 had results suggesting that tanning beds actually reduce the risk of skin cancer

-
16 had results within the margin of error – In an election, experts will say that you shouldn’t trust a poll that shows one candidate ahead by 1%, with a margin of error of 5%.



·
Some news stories are including a misleading statistic: that tanning beds increase the risk of melanoma by 75%. This number comes from a study with questionable methods. The study’s authors admit that they did not adjust for factors like outside sun exposure and sun sensitivity. Even if the study is accurate, it does not mean that 75% of tanning bed users will get melanoma, it means that their relative risk is higher. Because the issue is relative risk, when the original risk is very small, a percentage increase that looks big actually translates into a very small added risk.


· To use another example, your annual risk of a fatal car accident is about 0.013%. If that risk were increased by 75%, it would be 0.023%, or about 1 in 4,500. To put that number in perspective, the increase is 10 times smaller than the OSHA guideline for “acceptable risk.”
