What causes menstrual bleeding to resume after menopause at age 60?

Postmenopausal bleeding at age 60 may be caused by ovarian lesions, uterine diseases, or other reasons. When bleeding occurs after menopause, the first step is to perform a color ultrasound, as there may be an issue with the endometrium. Other possible causes include ovarian pathology or cervical lesions. A definitive diagnosis should be established through appropriate examinations, followed by targeted treatment based on the specific underlying cause.
