Abstract: Obstetrician-gynecologists are commonly the primary care physicians for many women and often play a crucial role in the diagnosis of breast cancer. Additionally, they will continue to provide follow-up care for many breast cancer survivors. This monograph focuses on the continuation of care for women with breast cancer. Current imaging modalities for the screening and diagnosis of breast cancer are addressed. Strategies for surveillance in breast cancer survivors as well as prevention strategies for patients at high risk for developing breast cancer are included. Treatment of breast cancer is multidisciplinary and encompasses the use of surgery, systemic chemotherapy, hormone therapy, and radiation therapy. Treatment-related issues such as common side effects and biological issues related to premature loss of ovarian function and reproductive issues are addressed, as are psychosocial issues unique to a diagnosis of breast cancer, including sexuality, body image changes, and fertility issues.
