Definition A cervical polyp is a small growth on or near the surface of the cervix. The cervix is the opening between the vagina and the uterus. Cervical polyps are usually benign, or noncancerous, and rarely cause symptoms.
What is going on in the body? Cervical polyps are formed when a group of cells, such as blood vessels within the cervix, form an abnormal growth. Cervical polyps are relatively common. They are seen more often in women over 20 years of age who have given birth to many children. They are rare before puberty and after menopause.
Most cervical polyps are benign, but all should be removed and examined with a microscope. Malignant changes may occur, and cancer of the cervix may first be seen as a large polyp. The chance of malignant change in a cervical polyp is less than 1%.
What are the signs and symptoms of the condition? Many cervical polyps do not cause symptoms. They are found by chance during a routine pelvic examination. Cervical polyps may cause vague symptoms such as the following:
What are the causes and risks of the condition? It is not known what causes cervical polyps. Their growth may be aided by estrogen, a female hormone, or by chronic cervical infection, known as cervicitis. Such chronic inflammation creates more blood vessels within the cervix, which may eventually form a cervical polyp.
What can be done to prevent the condition? Little can be done to prevent cervical polyps. Routine pelvic examinations may decrease the risk of cancer of the cervix developing from the polyp.
How is the condition diagnosed? Many cervical polyps do not cause symptoms and are found by chance during a routine pelvic examination that includes a Pap smear . During a pelvic examination, the cervix, vagina, and vulva are checked for signs of changes. To do a Pap smear, a doctor uses a small spatula and a brush to gently scrape cells from the cervix. These cells are sent to a laboratory for testing.
What are the long-term effects of the condition? Since 99% of polyps are benign, there are no serious long-term problems. Vaginal bleeding patterns may be unpredictable. There is a less than 1% risk that cervical polyps may become cancerous.
What are the treatments for the condition? A cervical polyp can be removed with a simple procedure in the doctor's office. The doctor gently twists the stalk of the polyp and removes it. Removal of a polyp is called a polypectomy. Other methods include tying the base of the polyp to minimise bleeding.
Larger polyps with a thick stalk may be removed using electrical current, a procedure known as LEEP. Larger polyps may also be vaporised with laser surgery.
What are the side effects of the treatments? Removal of the polyp usually produces minimal cramping and bleeding. Following are side effects of laser surgery and LEEP:
What happens after treatment for the condition? Women who have an abnormal PAP smear accompanied by a cervical polyp will need close follow-up with pelvic examinations and PAP smears. Cervical polyps may recur if the stalk was not completely removed.
How is the condition monitored? Routine pelvic examinations are done to check for any recurrence of the cervical polyp. Any new or worsening symptoms should be reported to the doctor.
