A new study shows part of the reason why men are three times more likely than momen to get skin cancer. Although medical science does not know why, researchers at Ohio State University might have the answer. They found that male mice have lower levels of an important skin antioxidant than female mice. They also have higher levels of cancer-linked inflammatory cells. This skin antioxidant is called catalase. It inhabits skin cancer by cleaning up hydrogen peroxide and other DNA-damaging reactive-oxygen compounds that are formed during exposure to UVB. UVB, or ultra violet B light, is a common source of sunburn and cancer-causing skin damage. Studies show links of low catalase activity to skin cancer. Researchers say women have more natural antioxidant skin protection than men do, which is why men may be more susceptible to oxidative stress in the skin. This then raises the risk of skin cancer.
