Preventing Skin Cancers

There are lots of theories about preventing skin cancer, but little evidence based on human trials. Higher levels of vitamin D are needed to prevent some cancers. So, regular, moderate exposure to sunlight may yield some protection. A diet conducive to protecting healthy cells and destroying damaged cells is theorized to be beneficial. Healthy cells are protected by a diet rich in the pigments from the whole spectrum of cartenoids, esp. astaxanthin, beta-carotene, etc., together with the fern, polypodium leucotomos, along with foods that increase levels of catalase, glutathione peroxidase and superoxide dimutase enzymes. Based on animal studies, it is conjectured that caffeine consumption before endurance running may help in destroying damaged cells. This, of course, could be combined with the topical application of noni juice to prevent basal cell growth. No proof that any of this works, but I am personally not will to take the chance involved in not trying.
