HPV is an abbreviation of human papillomavirus and is a sexually transmitted disease caused by spherical DNA virus infection. Common symptoms are verruca vulgaris, genital warts (condyloma acuminatum), cervical cancer anal cancer, etc.
The main types of HPV are HPV1, 2, 6, 11, 16, 18, 31, 33 and 35, among which the long-term infection of HPV16 and 18 is related to female cervical cancer.
How many tumors can HPV make?
HPV exists on various mucous membranes with an infection rate as high as 80%, but why does most people not develop into a major life-threatening disease?
HPV has roughly four subtypes :
- Low-risk skin type: including HPV 1, 2, 3, 4, 7, 10, 12, 15, etc. , this type of hazard is generally considered only with common warts, flat warts, warts and other related;
- Skin risk type: including HPV 5, 8, 14, 17, 20, 36, 38. This type is associated with a number of malignant tumors, including vulva, penile, anal, prostate, bladder cancer;
- Mucosal low-risk type: such as HPV 6, 11, 13, 32, 34, 40, 42, 43, 44, 53, 54, etc., can infect the genitals,, mouth and throat, esophagus mucous membranes, generally do not think that the tumor will induce;
- High-risk types of mucosa: including HPV-16, 18, 30, 31, 33, 35, 39, this is what we have been talking about “that” HPV, it is closely related to cervical cancer, rectal cancer, oral cancer, letonsof cancer and so on.
The malignant tumors that HPV can cause at the same time include vulva, penis, anus, prostate, bladder, cervix, rectum, oral cavity, tonsil, etc.
The incidence of high-risk skin tumors is relatively low, and the incidence of mucosal high-risk cancers is relatively high. Therefore, HPV16 and 18 are the biggest destroyers to human health among HPV subtypes.
HPV infection route
- Ways of sexual transmission;
- Close contact;
- Indirect contact: through contact with infected persons’ clothing, articles for daily use, utensils, etc.
- Iatrogenic infection: medical personnel are not well protected during treatment and nursing, resulting in self-infection or transmission to patients through medical personnel;
- Mother-to-child transmission: it is the close contact of infants through the birth canal of pregnant women.

Common Mistakes of Cervical Cancer and HPV
Myth 1: Only women will be infected with HPV
Corrigendum: Men are also infected and cannot be spared.
Myth 2: HPV infected people will have obvious symptoms
Corrigendum: Most HPV infected people do not know that they have been infected and have no obvious symptoms. Some HPV infections will subside within 2 years, but not everyone is so lucky.
Myth 3: Without sex life, HPV will not be infected
Corrigendum: HPV is transmitted through sex in most cases, even people who do not have sex can be infected. Condoms help prevent infection, but they are not 100% preventable.
Myth 4: HPV Infection Cannot Be Pregnant
Corrigendum: HPV infection does not affect most pregnancies. Problems found in routine screening need to be treated under the guidance of doctors.
Myth 5: Women of any age can be tested for HPV
Corrigendum: HPV testing is recommended after the age of 30. Young women before the age of 30 have high immunity, and most HPV infections can be eliminated by their own immunity.
Myth 6: HPV infection can cause cervical cancer
Corrigendum: Not all HPV infections cause cancer. Only high-risk HPV and persistent infection can lead to cervical cancer.
Myth 7: Middle-aged and elderly people need not worry about cervical cancer
Corrigendum: The incubation period of cervical cancer usually lasts for more than ten years. If HPV infection at the age of 40 is not eliminated in time and uterine screening is not done, the virus may still exist in the cervix.
Myth 8: HPV Vaccine Can Effectively Protect Lifetime
Corrigendum: The vaccine is most effective in 10 years, and the protective power decreases year by year thereafter. Vaccines cannot prevent all HPV types that can cause cervical cancer. Vaccines should still be screened regularly.
How to Prevent Cervical Cancer Caused by HPV
Early detection, early treatment, early cure, prevention and screening are more important than treatment. Screening and prevention cannot be compared.
For any cancer that cannot be effectively prevented, reliable screening can be used to achieve early detection and treatment.
Cervical cancer is the only cancer type that has both vaccine prevention and reliable technology screening.
Both countries and individuals should pay attention to prevent this kind of cancer.
