乳腺癌是女性最多见的恶性肿瘤之一。在我国女性中,仅次于子宫茎癌,排列第二位。但在某些地区或某些行业中进行肿瘤调查时它又占第一位。在乳腺癌患病者中男性约占10％,患病年令多在40—60岁之间。25岁以下的青年妇女很少发现患乳腺癌的。但年令超过30岁以后患病人数就迅速增多。因此提示我们中年妇女应特别注意自我保健。 Breast cancer is one of the most common malignant tumors in women. Female in our country, second only to cancer of the uterus, ranked second. But in some areas or some industries in the tumor investigation it again took the first place. Male patients account for about 10% of breast cancer patients, the prevalence of more than 40-60 years of age. Young women under the age of 25 are rarely found to have breast cancer. However, the number of sick people over the age of 30 is rapidly increasing. Therefore, we suggest that middle-aged women should pay special attention to self-care.
