What is LEEP?

Loop electrosurgical excision procedure (LEEP), uses a low-voltage electrical current to remove abnormal tissues of the cervix. It has an advantage, therefore, over the destructive techniques (CO2 laser and cryocautery) in that an intact tissue sample for analysis can be obtained. LEEP also is popular because it is inexpensive, simple, and typically has few risks or side effects. LEEP is also known as large loop excision of the transformation zone (LLETZ).

This procedure is used most often for treating mild to moderate dysplasia (abnormal changes of the cells lining the cervix or precancers) that have been identified by colposcopy and/or cervical biopsy. In certain situations, severe dysplasia and noninvasive cancer that are localized and can be removed, may also be treated by LEEP.

• Pap Smear - Read about Pap smear, a test to screen for cervical cancer, and precancerous changes in the cervix. Risk factors for abnormal Pap include HPV, smoking medicaitons, and a weakened immune system.
• Cervical Cancer - Get the facts on cervical cancer causes (HPV or human papilloma virus), symptoms, diagnosis (abnormal Pap smear), prognosis, treatment, research, stages and statistics.
• Douching (Vaginal Douche) - Learn why doctors do not recommend vaginal douching. Douching increases the risk for vaginal infections, ectopic pregnancy, pelvic inflammatory disease, and other conditions.
