An endometrial polyp. The endometrial (uterine) lining has the potential for rapid growth, part of the reproductive cycle, a potential that can persist into the menopause. When one part of the uterine lining grows faster than the rest, it bunches up and forms a finger-like polyp. Polyp is a generic term for this uneven growth anywhere there are mucous membranes: vocal cords, intestinal tract, nose.
In the uterus they can be the cause of abnormal (e.g. postmenopausal) bleeding and rarely can display malignant changes. During a hysteroscopy a camera is inserted through the cervical canal into the uterus. Here the camera has just entered the cervix and already the polyp is visible. A device with a rotating cutting head and suction removes the polyp in a matter of seconds.
