Hello,
Postmenopausal bleeding is always concerning and deserves an evaluation. Causes of postmenopausal bleeding include endometrial polyp(s), endometrial hyperplasia (overgrowth of normal tissue) or endomterial cancer; additionally, sometimes women can have bleeding from atrophy (a too thin endometrial lining).
The evaluation for this typically involves a physical exam, a pelvic ultrasound and an endometrial biopsy (sampling of the tissue inside the uterus to assess for hyperplasia or cancer), and when the biopsy is benign (ie, not hyperplasia or cancer) and the endometrial lining is thick, evaluating the inside of the uterus by hysteroscopy or sonohysterogram for a polyp.
Best regards,
Dr. Downing
