Endometrial polyps are tissue growths in the endometrium, or tissue lining the uterus. These polyps are usually benign, but they may be cancerous or develop into cancer in some cases.

Polyps are more likely to affect women between the ages of 40 and 50, who are entering or going through menopause. Other risk factors for polyps include obesity, high blood pressure or those on tamoxifen, a breast cancer medication.

Symptoms of polyps include heavy or irregular menstrual bleeding, abnormal bleeding between periods, bleeding in post-menopausal women, bleeding after sex and infertility. If diagnosed, endometrial polyps are typically removed during a hysteroscopy due to the risk of cancer.
