Oral Contraceptives and Breast Cancer: Oral Contraceptives and Breast Cancer:Issues Related to Age, Duration of Use, Dose, and Latent Effects

摘要

The report addresses the relative risk of breast cancer associated with prolongeduse of oral contraceptives. Several studies are discussed which suggest that use of oral contraceptives may increase the risk of very early-occurring breast cancer, and that a dose-response relationship may exist between the risk of breast cancer, the age at starting, and the length of time oral contraceptives are used.
