乳腺癌是女性乳房最常见的癌肿,占女性全身各种恶性肿瘤的7—10％,仅次于子宫颈癌。据资料介绍,上海市1971年乳腺癌的发病率为18.10人/10万人口,我国每年乳腺癌的死亡率为2.61人/10万人口。乳腺癌多发在40～60岁的妇女,其中45～49岁(更年期)和60～64岁为最多,这说明乳腺癌的发生与性激素的变化有密切关系。欧美国家的乳腺癌发病率更高,如美国每年乳腺癌的新发病例约有10万人,占妇女癌肿的首位。英国、丹麦、荷兰、加拿大平均每年乳腺癌死亡率为20～30人/10万人口,而委内瑞拉只有2—3人/10万人口。经追查结果表明,生活方式与乳腺癌的发病也有关系。
Breast cancer is the most common breast cancer in women, accounting for 7-10% of all malignant tumors in women, second only to cervical cancer. According to the information, the incidence of breast cancer in Shanghai in 1971 was 18.10 people / 100,000 population. The annual breast cancer death rate in China is 2.61 people / 100,000 population. Breast cancer in women 40 to 60 years of age, of which 45 to 49 years (menopause) and 60 to 64 years of the most, indicating that the occurrence of breast cancer and sex hormone changes are closely related. The incidence of breast cancer is higher in Europe and the United States. For example, there are about 100,000 new cases of breast cancer each year in the United States, accounting for the first place for women’s cancer. The average annual breast cancer death rate in the United Kingdom, Denmark, the Netherlands and Canada is 20-30 persons / 100,000 population, while Venezuela has only 2-3 / 100,000 population. The tracing results show that the way of life and the incidence of breast cancer are also related.
