Reproductive Considerations for Patients with Early-Onset Breast Cancer.

Purpose of review: Early-onset breast cancer presents various challenges in regard to reproductive health. This review examines the current data pertaining to issues such as fertility preservation, preimplantation genetics, the impact of chemotherapy and endocrine therapy, contraception, and pregnancy in the young breast cancer population.

Recent findings: Many breast cancer treatments such as chemotherapy and endocrine therapy can be gonadotoxic or teratogenic. Multiple fertility preservation options are now available to young breast cancer patients, including embryo and oocyte preservation, ovarian tissue preservation, and ovarian suppression with GnRH agonists. In patients with known cancer germline mutations, preimplantation genetic testing is an option.

Summary: Fertility preservation and other reproductive services are expanding and offer great promise to the early-onset breast cancer community. Providers must be knowledgeable about the various options in order to better empower patients.
