1. Human papillomavirus (HPV) is divided into two categories: A. tumorigenic (high-risk). B. non-tumorigenic (low-risk). Few women within 30 years of age are persistently infected after new HPV infection, but women over 30 years of age are more likely to show persistent infection, consistent with the increasing incidence of high-grade squamous intraepithelial neoplasia (HSILs) with age. Repeated detection of homozygous HPV infection suggests a risk of high grade lesions. 2. The recently introduced vaccines against HPV 16 and HPV 18 only protect against approximately 70% of cervical cancers caused by HPV16 and HPV18 infections. 3. What to do if cytology is negative but HPV is positive: A. Review in 12 months. B. Colposcopy. Both cytology and HPV are negative, and screening is done once every three years. 4. Cervical cancer screening should be started at the age of 21. 5. How to treat HPV high risk positive? HPV is a more difficult STD than AIDS. 20 million people have been infected in the United States, and condoms cannot prevent it. Both men and women can be infected with HPV, and the disease can even lead to cervical cancer in women, as HPV is transmitted directly through the skin, the use of condoms can not be prevented. HPV is still a virus that cannot be cured for the time being, and is prone to spread and cause cancer. Patients are generally infected with what they want to call “cauliflower venereal warts”, and women are more likely to suffer from cervical cancer, with 4,800 women dying of cervical cancer each year in the United States. 6, high-risk HPV common treatment methods A. Physical therapy: thermal destruction. B. Surgery: removal of HPV site (cervical amputation). C. Drug therapy: general vaginal placement of interferon, oral antiviral drugs and herbal treatment D. Therapeutic vaccine: there is no effective therapeutic vaccine.
