ntermittent sun exposure may increase lifetime risks of certain skin cancers, research suggests.
In the
(1/26) Your Health column, Kim Painter writes that "intermittent sun exposure" is what vacationers usually experience on holiday. Yet, a "history of such brief, intense sun blasts appears to raise lifetime risks of certain skin cancers, especially the most dangerous type, melanoma, says Marianne Berwick, an epidemiologist at the University of New Mexico." In fact, "those vacation sun soaks may be more dangerous than the constant, daily sun exposure that a farmer or construction worker gets." While the "relationship between skin cancers and sun exposure is complex and riddled with controversy," the "theory that a holiday sun blast carries special risk is gaining ground," and "one compelling recent study...found that young, white English women who had vacationed in hotter countries had more moles than women who had not." Furthermore, investigators "found excess moles were concentrated on the trunk and legs -- areas less likely to get the everyday English sun."
