The chances of developing cancer from postmenopausal bleeding are around 5% to 10%, depending on the individual. Postmenopausal bleeding can be caused by a variety of reasons. Diseases related to the vagina and uterus can lead to postmenopausal bleeding, and cancers such as endometrial cancer can also cause postmenopausal bleeding. It is important to note that endometrial cancer usually develops in the postmenopausal age group, often with irregular vaginal bleeding after menopause, and the probability of developing endometrial cancer is around 5-10%. Therefore, if irregular vaginal bleeding occurs after menopause, it is necessary to actively go to the hospital for gynecological examination to clarify the thickness of the endometrium and the specific hyperplasia of the endometrium. If necessary, diagnostic scraping should be performed according to the doctor’s prescription to guard against endometrial cancer.
