A new PSA for Style Network’s skin cancer prevention campaign is really making headlines. Maybe it has something to do with all of the women on the video going “naked” to talk about skin cancer. Meghan Mc Cain joins Tatyana Ali, Tempestt Bledsoe, CaCee Cobb, Danielle Fishel, Ashlan Gorse, Brandy and Jenn Proske to talk about prevention in the 30-second video. The thing to note is that they attest to doing their daily activities whilst nude — that is to say, whilst not wearing sunscreen. What are your thoughts about the use of this type of advertisement?

|The actual evidence is not so clear. limiting length of exposure is more important than wearing sunscreen.|
Does solar exposure, as indicated by the non-melanoma skin cancers, protect from solid cancers: vitamin D as a possible explanation.

Skin cancers are known to be associated with sun exposure, whereas sunlight through the production of vitamin D may protect against some cancers. The aim of this study was to assess whether patients with skin cancer have an altered risk of developing other cancers.
The study cohort consisted of 416,134 cases of skin cancer and 3,776,501 cases of non-skin cancer as a first cancer extracted from 13 cancer registries. 10,886 melanoma and 35,620 non-melanoma skin cancer cases had second cancers. The observed numbers (O) of 46 types of second primary cancer after skin melanoma, basal cell carcinoma or non-basal cell carcinoma, and of skin cancers following non-skin cancers were compared to the expected numbers (E) derived from the age, sex and calendar period specific cancer incidence rates in each of the cancer registries (O/E=SIR, standardised incidence ratios). Rates from cancer registries classified to sunny countries (Australia, Singapore and Spain) and less sunny countries (Canada, Denmark, Finland, Iceland, Norway, Scotland, Slovenia and Sweden) were compared to each other.
SIR of all second solid primary cancers (except skin and lip) after skin melanoma were significantly lower for the sunny countries (SIR(S)=1.03; 95% CI 0.99-1.08) than in the less sunny countries (SIR(L)=1.14; 95%CI 1.11-1.17). The difference was more obvious after non-melanoma skin cancers: after basal cell carcinoma SIR(S)/SIR(L)=0.65 (95%CI=0.58-0.72); after non-basal cell carcinoma SIR(S)/SIR(L)=0.58 (95%CI=0.50-0.67). In sunny countries, the risk of second primary cancer after non-melanoma skin cancers was lower for most of the cancers except for lip, mouth and non-Hodgkin lymphoma.
Vitamin D production in the skin seems to decrease the risk of several solid cancers (especially stomach, colorectal, liver and gallbladder, pancreas, lung, female breast, prostate, bladder and kidney cancers). The apparently protective effect of sun exposure against second primary cancer is more pronounced after non-melanoma skin cancers than melanoma, which is consistent with earlier reports that non-melanoma skin cancers reflect cumulative sun exposure, whereas melanoma is more related to sunburn.

|I agree with nudist_tj. The ad is using nudity as an attention getter, then flipping it to say "nudity is just as bad" as going out without sunscreen.|

|My wife just had a squamous-cell cancer removed from the top of her head. She has thin, formerly blond hair on her head, but this was no protection as far as the cancer was concerned. She has been instructed to wear a hat to protect her scalp. It's not an area where one would normally put sun-block.|

|I agree with you guys (nudist_tj & Sanman). The nudity part of the message is only to attract attention. They seem to try and capitalize on a fear of being naked.|
