Prenatal Care during and after Breast Cancer Treatment.

Cancer associated with pregnancy is defined by diagnosis during pregnancy, lactation, or the first year after delivery. The decision about type of treatment depends on the cancer stage and gestational age. Termination of pregnancy does not seem to modify the maternal prognosis for breast cancers. Interdisciplinary meetings and discussions are needed to evaluate and balance the maternal and fetal risks. In this chapter, we discuss about how to prevent or treat maternal and fetal complications of surgery and chemotherapy in pregnancy-associated breast cancer.
