Breast cancer is the most commonly occurring cancer in women and, until recently surpassed by lung cancer, was the leading cause of cancer-related death in women. It is the leading cause of death in women aged 39 to 44 years. The American Cancer Society has estimated that there will be 135,000 new cases of breast cancer and 42,300 breast cancer-related deaths in 1988. It is now predicted that breast cancer will develop in one out of every ten women in the United States. Given the clinical and public health significance of breast cancer, annual screening with mammography and clinical breast examination is recommended for women aged 50 and older to reduce breast cancer mortality.
乳腺癌是女性中最常见的癌症，直到最近被肺癌超越之前，一直是女性癌症相关死亡的主要原因。它是39至44岁女性死亡的主要原因。美国癌症协会估计，1988年将有135,000例乳腺癌新病例和42,300例与乳腺癌相关的死亡。现在预计美国每十名女性中就有一人会患乳腺癌。鉴于乳腺癌在临床和公共卫生方面的重要性，建议50岁及以上的女性每年进行乳房X光检查和临床乳房检查，以降低乳腺癌死亡率。
