It is not normal to have menstruation again after eight months of menopause, which may be related to atrophic vaginitis, menopausal syndrome, endometrial cancer or cervical cancer and other reasons. 1. Atrophic vaginitis: due to the decrease of estrogen level and local resistance after menopause, vaginal inflammation may occur, with congestion or bleeding spots on vaginal mucosa and bloody leukorrhea. 2. Menopausal syndrome: when the ovarian function state fluctuates and changes, the level of sex hormone fluctuates, menstrual disorders and irregular menstrual cycle may occur, so menstruation may come back after menopause. 3. Endometrial cancer: it is epithelial tumor of endometrium, with clinical manifestation of postmenopausal vaginal bleeding, the amount of which is usually not much, or vaginal discharge, which is plasma or blood secretion. 4. Cervical cancer: contact bleeding is often seen, and postmenopausal irregular vaginal bleeding can also be seen in elderly patients. If vaginal bleeding is found after menopause, it is recommended to consult doctor in time to identify the disease that causes vaginal bleeding and follow the doctor’s prescription for treatment.
