乳腺癌在世界范围内已成为妇女因癌症死亡的主要原因。据估计,在2000年,在发达国家,乳腺癌造成180,000名妇女死亡,发展中国家导致了184,000名妇女死亡。发达国家妇女患乳腺癌的风险在增加,在亚洲和非洲乳腺癌的发病率也在迅速上升。有专家分析,可能是由于社会经济和生活方式的改变(如晚育、食品结构的改变)以及一些与月经变化相关的因素导致乳腺癌的发生率上升。有人作过统计,相对于20多岁的妇女,30多岁的妇女发生乳腺癌的可能性要高10倍,40多岁的高40倍,50多岁的高60倍,
Breast cancer has become a major cause of cancer deaths in women worldwide. It is estimated that in the developed countries, 180,000 women died of breast cancer in the developed countries and 184,000 women died in developing countries. The risk of developing breast cancer among women in developed countries is increasing, and the incidence of breast cancer in Asia and Africa is also rapidly rising. Expert analysis may be due to changes in social economy and lifestyle (such as late childbirth, changes in food structure) and some factors related to menstrual changes leading to an increase in the incidence of breast cancer. Some people have made statistics. Compared with women in their 20s, women in their 30s are 10 times more likely to develop breast cancer, 40 times higher in their 40s, and 60 times higher in their 50s.
