But, in order to make this comparison, we must first define the words “safe” and “tan.”“Safe” can be defined ...

A new study indicates an association between skin cancer and Bsml, a receptor gene involved in vitamin D metabolism. The study, which will be published in the journal Cancer, suggests that genetic differences in Bsml are the reason that people have different levels of vitamin D, and that this means some people may have more vitamin D-related protection against cancer ...

In Part 1 of this series, we showed that there is no causal correlation between UVR and cutaneous malignant melanoma (CMM). Instead, we showed that a weak coincidental correlation resulting from the normal and natural response by the body to UVR (an increase in the number of melanocytes in the skin after exposure) has led to the incorrect belief that ...

The answer to this question is extremely important to the indoor tanning industry because, if UVR can be scientifically proven to cause CMM in humans, the survival of the industry is in jeopardy. On the other hand, if the scientific evidence shows that exposure to sunlight, ...
