Breast Cancer and Menopause

Breast cancer treatments such as chemotherapy; hormone therapy, i.e., aromatase inhibitors (including Tamoxifen, Anastrozole, Letrozole, Exemestane); or ovarian suppression, which stops the ovaries from working either permanently or temporarily, can trigger menopause symptoms. Aromatase inhibitors can, in fact, make the menopause symptoms more intense. Menopause is not a cause of breast cancer, but the risk of breast cancer increases with age.
