In the Nordic countries, breast cancer, is the most common malignant disease among women and the incidence has been increasing steadily for the past 30 years. The age-specific incidence curve of female breast cancer suggests that the menopause has a protective effect. Nordic studies have provided evidence of an increased breast cancer risk in women of low parity, those who have their first child late, and those who have used oral contraceptives and hormone replacement therapy for a long time.
在北欧国家，乳腺癌是女性中最常见的恶性疾病，且在过去30年中发病率一直在稳步上升。女性乳腺癌的年龄特异性发病率曲线表明，绝经具有保护作用。北欧的研究已证实，生育次数少、首次生育年龄晚、长期使用口服避孕药和激素替代疗法的女性患乳腺癌的风险会增加。
