Black Skin Can Be A Symptom Of Cancer Risk

Traditionally we used to believe that black skin can be caused from dying and direct exposure to ultraviolet light (UV) radiations, but it can induced skin cancer according to a recent analysis. Originally skin cancer reasons were rejected as they are likely to create pressure about having black skin. This was so because of a belief rarely fatal at age young sufficient to involve reproduction. According to a new paper that has been published in the Proceedings of the Royal Society B, has been providing evidences about black people and the albinism of parts from Africa with highest exposure degree of UV radiation. Professor Mel Greaves, Director of the Centre for Evolution and Cancer at The Institute of Cancer Research, London, said: "Charles Darwin thought variation in skin color was of no adaptive value and other investigators have dismissed cancer as a selective force in evolution. But the clinical data on people with albinism, particularly in Africa, provide a strong argument that lethal cancers may well have played a major role in early human evolution as an important factor in the development of skin rich in dark pigmentation - in eumelanin."
