Bleeding a few years after menopause is an abnormal uterine bleeding, commonly known as “backward flowering”. It can be caused by malignant lesions of the cervix, inflammation of the vagina or cervix, endometrial lesions, polyps, or malignant lesions of the endometrium. Therefore, if you have postmenopausal bleeding, you should go to the hospital in time to have a gynecological examination to find out whether there are cervical polyps or vaginal inflammation causing bleeding. A cervical cancer screening test should be performed to find out if there are precancerous lesions in the cervix. Ultrasound examination should also be performed to understand the condition of the uterine adnexa and the endometrium, whether there is uneven echogenicity or abnormal thickening of the endometrium. According to the results of the examination, effective treatment should be given to the patient. If it is cervical polyp, cervical polyp removal should be performed; if it is vaginal inflammation, vaginitis treatment should be given in time; if it is some malignant lesion, surgery should be performed in time.
