What are cervical polyps? Cervical polyps are common growths that form in the uterine cervix. The exact reason why polyps form is not understood, but their development may be related to increased levels of estrogen. Polyps may also develop as the result of chronic inflammation in the cervical region or congestion in the cervical blood vessels. The size of the polyps varies, and some women may have multiple polyps. Cervical polyps most often occur in women over age 20 and are rare in premenstrual girls. Some women with cervical polyps have no symptoms at all, while others may have abnormal bleeding during menstruation, after sexual intercourse, or following vaginal douching. The large majority of polyps are benign (not cancerous). In rare cases, though, polyps may contain precancerous or cancerous cells. It is rare for cervical polyps to result in serious complications. However, if vaginal bleeding becomes severe, the significant loss of blood could lead to shock, which could require emergency hospitalization and blood transfusions. Symptoms of significant blood loss include light-headedness, dizziness, fainting, or difficulty breathing. The treatment of cervical polyps is removal, which can be performed in a relatively minor office procedure. Cervical polyps are rarely a serious condition, but severe vaginal bleeding can lead to significant blood loss. Seek immediate medical care (call 911) if you, or someone you are with, experience bleeding that will not stop, rapid heart rate, difficulty breathing, pale skin, or fainting. Seek prompt medical care if you are being treated for cervical polyps but mild symptoms recur or are persistent.
