Oncolactation for Patients with Breast Cancer: Executive Summary from the American Society of Breast Surgeons

Helen M Johnson et al. Ann Surg Oncol. .

Abstract

Despite increasing rates of pregnancy-related and postpartum breast cancers and growing recognition of oncofertility as an important component of survivorship, few guidelines exist to guide surgical oncologists in managing lactation during or after breast cancer treatment. To address this need, the American Society of Breast Surgeons developed evidence-based oncolactation recommendations for breast cancer patients. This review outlines the management of patients with breast cancer diagnosed during pregnancy or lactation, and provides guidance regarding surgery, radiation, and systemic therapy. It also reviews strategies for supporting lactation following breast cancer treatment and discusses screening in the pregnant and lactating population.

Keywords: Breast cancer; Breastfeeding; Lactation; Oncolactation; Postpartum; Pregnancy; Screening; Survivorship.
