阳光能抗癌吗?(通讯员稿)

[ 2006-12-11 16:39 ]

我们都知道强烈的阳光辐射会导致癌症,殊不知阳光也是抗癌的自然药物。下面我们就来看看它是如何抗癌的。

Although too much exposure to the sun's ultraviolet rays can cause skin cancer, sunshine may have protective effect against some cancers, a U.S. scientist said in April. He said vitamin D, the so -called sunshine vitamin can help to slow down the speed at which cancer cells divide. It is abundant in cod liver oil, fortified milk and dairying products, and some fatty fish. The study found inverse associations between both residential and occupational exposure to sunlight and mortality from female breast and colon cancers.

Scientists found the more deaths from skin cancer in sunnier states but the number of people who died from the other cancers was lower in sunshine area. Working outdoors in a sunny climate was also associated with fewer breast and colon cancer deaths but not with the other cancers.
