Cervical cancer is caused by infection with the human papillomavirus, or HPV, which has high-risk and low-risk types. The more common types are 16, 18, 52, 53 and other high-risk viruses. For women who have had children and are sexually active, annual cervical cancer screening, including cytology and HPV testing, is recommended. If the HPV virus is detected as a high-risk type, it depends on the cytology test results to see if a cervical biopsy is needed. If a cervical biopsy is performed and a cervical precancerous lesion is identified, further cervical surgery is required. Cervical laparotomy can be done, followed by further pathology to confirm the diagnosis. If HPV infection is present but the cervical biopsy is not abnormal, vaginal medication can be used, usually without interferon to clear the virus. It should also be combined with your body’s resistance, exercise to enhance resistance, plus medication to help clear the HPV virus.
