Bleeding in a 53-year-old woman three years after menopause may be caused by a small amount of endometrial exfoliation due to low-dose estrogen stimulation, or it may be caused by a localized problem of the cervix, such as cervical cancer. After menopause, although the ovarian function is declining, there is still a low dose of estrogen in the body to stimulate the endometrium, so it may cause a small amount of vaginal bleeding due to prolonged hormonal stimulation and endometrial hyperplasia and endometrial exfoliation, which is often treated like menstruation. The bleeding will also feel like menstruation. However, for some women, it is considered to be caused by localized cervical problems, because cervical cancer tends to occur at the perimenopausal stage and often causes irregular vaginal bleeding after menopause, so if bleeding occurs at this time, it is necessary to go to the gynecology department for internal examination and ultrasound to confirm the exact cause of bleeding. If cervical cancer is considered, colposcopic biopsy is also needed to confirm the diagnosis. Once the diagnosis of cervical cancer is confirmed, the patient will need to be hospitalized as soon as possible for surgery to remove the uterine adnexa and remove the pelvic lymph nodes, and may need radiotherapy after surgery.
