Here, a beam of light is directed on the abnormal area and the heat kills the cells. Precancer is a warning that you are at risk of developing cancer. Therefore, if your pap test suggests a precancerous change in the cervix, it is in your best interest to seek further evaluation as soon as possible. Close, careful monitoring through pap smears and colposcopy is essential in preventing precancerous lesions from progressing to invasive cancer. However, these treatments are both more complicated and more prolonged than the treatments for precancers described above.
Cure rates are also lower, depending on the extent of the cancer.
If you detect and eliminate precancerous lesions promptly, your chances for a cure are excellent. From 90-95 percent of women treated by cone biopsy, the LEEP procedure, and laser are cured. Five percent of patients need retreatment. You can reduce your risk of cervical cancer and other precancerous abnormalities by getting routine pap smears and protecting yourself against the HPV virus. If you smoke, giving up cigarettes will also cut your chances of cervical cancer.
