Prevent skin cancer

Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight.

There are three major types of skin cancer — basal cell carcinoma, squamous cell carcinoma and melanoma. 皮肤癌（皮肤细胞的异常生长）最常发生在暴露于阳光下的皮肤上。 但这种常见的癌症也可能发生在通常不暴露在阳光下的皮肤区域。

皮肤癌主要分为三种类型：基底细胞癌、鳞状细胞癌和黑色素瘤。
