Definition
By Mayo Clinic staffUterine polyps are growths attached to inner wall of the uterus and protruding into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps. The sizes of uterine polyps range from a few millimeters — no larger than a sesame seed — to several centimeters — golf ball sized or larger. They are attached to the uterine wall by a large base or a thin stalk.
You can have one or many uterine polyps. They usually stay contained within your uterus, but occasionally, they may slip down through the opening of the uterus into your vagina. Although they can happen in younger women, uterine polyps most commonly occur in women in their 40s and 50s.
