Ovariectomy is definitely beneficial to the prognosis of breast cancer because the ovaries will no longer secrete female estrogen and progesterone periodically, especially the significant decrease of estrogen will greatly reduce the recurrence of breast cancer, and the valuable ovaries should never be removed just because of breast cancer. Especially for young women, the ovaries have irreplaceable physiological functions, which can secrete estrogen and progesterone periodically, maintain the unique female sexual characteristics, lead to regular cyclic shedding of the endometrium, and prevent cardiovascular diseases and osteoporosis, so if the ovaries are blindly removed, the losses will be more than compensated. For breast cancer patients is surgery to remove the lesion and take the necessary chemotherapy, radiotherapy and post-operative drug support, do not get pregnant again and review regularly. Keep a good attitude and eat less food containing more estrogen such as soy products and royal jelly in daily life. Unless metastasis to the pelvis, it is not necessary to remove the ovaries.
