Belly shots for breast cancer usually refer to ovarian function inhibitor drugs, also called menopause shots, which can be used as a method of endocrine therapy for breast cancer. The drugs commonly used in clinical practice are goserelin and leuprolide. Belly shots can inhibit ovarian function in premenopausal women and inhibit the production as well as secretion of estrogen to treat breast cancer and prevent recurrence of the disease. Breast cancer is a common malignant tumor in women. For patients with estrogen receptor-positive breast cancer, endocrine therapy is required. If the hormone level in the body is too high, it will easily cause cancer cells to spread and cause breast cancer to recur. If belly shots are given, it can effectively inhibit the production of ovarian estrogen, thus reducing the risk of recurrence and improving the survival rate of breast cancer patients. However, not everyone needs belly shots. For post-menopausal breast cancer patients, the estrogen in the body is mainly converted from androgens, and aromatase inhibitor drugs can be used. For pre-menopausal breast cancer patients, estrogen is mainly secreted by the ovaries, so anti-estrogen therapy should be given along with the inhibition of estrogen production by the ovaries.
