Estrogen deprivation therapy

Estrogen deprivation therapy
Specialty	oncology/or endocrinologist

Estrogen deprivation therapy is a form of hormone therapy that is used in the treatment of breast cancer. Modalities include antiestrogens such as selective estrogen receptor modulators (SERMs) like tamoxifen, selective estrogen receptor degraders like fulvestrant, and aromatase inhibitors like anastrozole and ovariectomy.
