Study sheds light on how the sun causes skin cancer

Researchers at Dana-Farber Cancer Institute have made a discovery that could help solve a mystery in cancer biology: how a sunburn acquired during a childhood day at the beach can develop into a deadly tumor decades later. The scientists report in the Feb. 4 Proceedings of the National Academy of Sciences that the sun’s damaging ultraviolet (UV) rays target a series of biochemical signals inside the young skin cell, impairing the cell’s ability to control its proliferation. The paper currently is available on the journal’s web site.
