"Evidence that the Sun Protects You from Melanoma
Studies show that those who spend the most time outdoors have the lowest risk of melanoma.2,3,4 This includes a review of more than 50 research papers. It revealed that people who work outside have the lowest incidence of the disease. For example, lifeguards, construction workers and farmers have much lower rates than office workers.5
Another study reviewed all the published research in the International Journal of Cancer. It also showed that people with “heavy occupational exposure” have significantly lower risk.6
A similar study was performed by researchers at the University of Sydney’s Melanoma Clinic. Their results showed that office workers develop melanoma at twice the rate of lifeguards. Those who had the lowest incidence were sunbathers!
Population studies also show an inverse relationship between sun exposure and melanoma. For example, rates of the disease are higher in Minnesota than Arizona. They are also higher in Norway than the South of France.
Then there is the inconvenient truth that melanoma lesions frequently occur on parts of the body leastexposed to sunlight. This includes the soles of the feet, under the nails, on the genitals and inside the nose and mouth.
The evidence clearly shows that those who spend more time in the sun (without burning) have less risk of melanoma. That is quite the opposite of what the anti-sun proponents would have you believe."
Does Sunscreen Cause Skin Cancer?
======================
"Findings on the anatomical site of melanoma from this study suggest a protective role for brief, regular exposure to sunlight and fit with recent laboratory studies that have shown vitamin D to suppress growth of malignant melanoma cells in tissue culture. A mechanism is proposed in which vitamin D inhibits previously initiated melanomas from becoming clinically apparent."

'The results suggest that short-term exposure to unusually intense sunlight increases the risk of melanoma, while long-term constant exposure has no effect or may decrease risk."

'"The evidence relating cutaneous malignant melanoma to previous sun exposure is now very strong. Major northern hemisphere studies consistently show increases in melanoma in association with recreational and vacation activities related to intermittent sun exposure. These studies have also recorded amounts of sun exposure from such activities. Several studies suggest an increased risk related to short periods of intensive exposure in early adult life. In contrast, regular outdoor occupation confers a decreased risk in these same studies. "
