Pregnancy and Chemotherapy for Breast Cancer

During your chemotherapy treatment for breast cancer, you may stop having monthly menstrual periods. You still can get pregnant, however, so talk with your doctor about birth control. The effect of chemotherapy on an unborn baby is unknown. After your treatment is over, your ability to get pregnant will depend on your age and the types of drugs you received. If you hope to become pregnant after treatment, talk with your doctor before starting chemotherapy (see Breast Cancer and Pregnancy for more information).
