Cervical polyps are small, elongated tumors that grow on the cervix. The cervix is the narrow canal at the bottom of the uterus that extends into the vagina. The cervix connects the uterine cavity and the upper portion of the vagina. It acts as the passageway for sperm to fertilize an egg, which could result in pregnancy. During labor, the cervix becomes thinner and wider.
The cervix is a tubelike channel that connects the uterus to the vagina. Cervical polyps are growths that usually appear on the cervix where it opens into the vagina. Polyps are usually cherry-red to reddish-purple or grayish-white. They vary in size and often look like bulbs on thin stems. Cervical polyps are usually not cancerous (benign) and can occur alone or in groups.
