80% of girls are infected with venereal disease virus HPV you know how much?
▌ Hpv what is the ghost?
Hpv (human papillomavirus), an episode of epidermal virus that infects the skin and mucous membranes. About 100 species, divided into two categories, low-risk type and high-risk type.
These HPVs can cause genital warts or very weak cervical cell changes. Among them, HPV 6 and 11 are the most common low-risk HPVs, and 90% are associated with genital warts.
High-risk HPV can cause abnormal changes in cervical cells. For abnormal changes in the cells if not treated in time, it may develop into cervical cancer. The 13 most common types of high-risk HPV are 16,18,31,33,35,39,45,51,52,56,58,59 and 68. Of which type 16 and type 18 are the most common, about 70% of cervical cancer are related to them. A study by the National Cancer Institute found that about 10% of women infected with HPV types 16 and 18 develop a high degree of cervical precancerous lesions (CIN 3) within 3 years of infection (about 9% of women with other high-risk HPV types 4% of cases), 20% of women develop a high degree of cervical precancerous lesions within 10 years (about 7% of other high-risk HPVs).
Continuous high-risk HPV infection is a necessary condition for cervical cancer. By detecting HPV virus early detection and comprehensive prevention and treatment of cervical cancer.
▌ How do I know if I have HPV?
Low-risk HPV infection performance:
The benign appearance on the skin is manifested as verruca-like appearance of the hand, foot, and special areas, such as the nostril neck. External genital diseases (genital warts) benign performance of visible and invisible three states, respectively, the typical performance, clinical infection, latent infection.
Typical performance: the formation of papillary tumor, cauliflower-like, granular, chicken coronal. May be multiple or single , usually soft, damp, fleshy red protrusions or flat, different sizes. Warts infected with HPV generally do not appear red or brown . It should be noted that some warts are very small, even in vitro is difficult to see through the naked eye.
Mainly occurred in: female genital, vaginal, cervix and anus around the anal canal, urethra; men's vulva, penis, testicular surface, urethra, anus, anal canal and so on. Rare in: armpits, umbilical fossa, toes, breast under the scull.
High-risk HPV infection manifestations: skin cancer and cancer.
Possible symptoms of cervical cancer:
Abnormal vaginal discharge or bleeding (especially after sexual intercourse).
Pee pain (especially if the lower abdomen is also painful).
▌ HPV is how to get infected?
HPV is a virus that is transmitted mainly through sexual transmission, close contact and indirect contact. In addition, infants may cause harm to their babies through contact with the pregnant woman's birth canal.
HPV is a sexually transmitted infection for most women, and about 80% of new women are at least infected with HPV and are completely immune to the health of their body's immune system before they cause abnormal changes in their cells, Can not be tested. Most infections can be automatically eliminated within a year or two by the autoimmune suppression, will not cause disease.
Low-risk HPV is also transmitted through close contact with the genitalia, genital warts can affect the local immunity, for high-risk HPV persistent infection to create the conditions, if infected with genital warts, active treatment should be the main test whether infected with high-risk type.
Men infected with the HPV virus, due to the particularity of the physiological structure, basically can be cleared by their own immunity. Men's transmission is basically through sexual infection, whether daily life can be infected is inconclusive. Infection with HPV by men is not a disease in itself, and most people can be cleared by their own immunity. Even low-risk genital warts can be treated, high-risk type of cancer is very rare.
Condoms have some protection, but they do not completely prevent infection because they do not cover the entire genitalia. Multiple sexual partners increase the risk of HPV infection.
▌ HPV is not sexually transmitted diseases?
HPV can be said that it is a cold in STDs. People often confuse HPV infection with other sexually transmitted diseases such as herpes and HIV. These diseases can occur simultaneously in an individual, HPV infection differs from other types of sexually transmitted diseases.
Genital HPV infection is very common and 80% of women have a chance of getting infected. Simple HPV infection does not require treatment, only when persistent infection causes cervical intraepithelial lesions only need treatment.
Currently there is no HPV test for men, can not determine exactly what time, from who infected with HPV, do not need to pursue sexual partners.
Although each sexually transmitted disease varies, it can amplify each other if they occur simultaneously. HIVIDS reduce the immunity of women, and the risk of developing cervical cancer is increased if they are also infected with HPV.
▌ HPV prevention and detection.
There are currently two types of HPV vaccines that have been approved: Gardasil and Cervarix, which are mainly used to prevent HPV types 16 and 18 associated with 70% of cervical cancers. In addition, Gardasil prevents the two most common forms of low-risk HPV that cause genital warts, types 6 and 11. No protective effect on other carcinogenic HPV infection. In addition, vaccines protect girls and young women who have not yet been exposed to HPV. For women who have been infected, the protective effect of the vaccine is still in the research and development stage.
Maintain as few sexual partners as possible.
Condoms do not cover the entire penis and therefore can not completely avoid HPV infection. A paper published in the Journal of Medicine, TheNew England, states that sticking to condoms can actually reduce the risk of HPV infection.
Because smoking affects the body's immune system, smoking is prohibited.
And pregnant women, like folic acid and multivitamins. The latest study found that women with higher levels of folic acid (a B-family vitamin) had a lower risk of HPV infection and had a lower chance of persistent infection if they had been infected with HPV.
The digene HPPV test is the first HPV testing technology to pass both the US FDA, European CE and Chinese SFDA certification. The digeneHPV test simultaneously detects the 13 most important high-risk HPV types, HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and 68. (Although QIAGEN products can also detect low-risk HPV, they are generally not recommended for routine screening).
For women over the age of 30, we recommend routine testing of HPV and cytology. Although the age of women infected with HPV at this age decreased, but due to decreased immunity, the possibility of persistent infection increased, easy to progress to cancer, is a high incidence of cervical cancer. Accuracy up to 100% if combined screening.
Women under the age of 30, due to active sexual activity, the risk of infection is relatively high, but because of the relatively strong immune system, most are transient infections, do not need routine HPV testing. Medical experts recommend that women of any age should be tested.
In causing cervical lesions on duty, HPV infection may be latent for months or even years. If the cytology results are normal, HPV positive, there is a risk, one year after the review. If the HPV test results continue to be positive, regardless of cytological findings, further evaluation is required.
Cervical cancer is almost 100% preventable by combined screening of cytology and HPV testing on a regular basis.
▌ HPV treatment.
There are currently no antibodies or other drugs against the HPV virus. Fortunately, before the HPV virus causes the disease, it usually disappears automatically or is reduced to a lower level by the body's own immunity. If the infection persists, the current approach is also to treat HPV-induced cytological changes such as the application of aggregates, creams, lasers or other techniques to treat genital warts. Precancerous lesions of the cervix can also be surgically removed, such as LEEP (a technique that uses electrical energy) or laser treatment. If you have developed cervical cancer, usually require hysterectomy and chemotherapy.
The main treatment of genital warts are: self-medication and doctor treatment. There is no clear data to show that there is a significant difference between the two methods.
Doctor treatment methods:.
Cryotherapy, the wart frozen to eliminate.
Trichloroacetic acid, suitable for wet parts, smaller wart body.
Electrocautery surgery, burn the wart by electric current.
Laser treatment, the use of glare to wart body burning volatile, mainly for larger wart, or other methods of treatment is invalid.
Surgical resection is useful when the number of warts is small and the volume is small, or when it can not be determined whether it is a wart caused by a low-risk HPV infection.
Young women are very susceptible to HPV, but women in this age group are less likely to develop cervical cancer because of their relatively high resistance. Women over the age of 30 are less susceptible to HPV, but the virus is more likely to lurk for longer periods of time and cause abnormal changes in the cell.
Among them, HPV 6 and 11 are the most common low-risk HPVs, and 90% are associated with genital 濕疣 warts.
A study by the National Cancer Institute found that about 10% of women infected with HPV types 16 and 18 develop a high degree of cervical precancerous lesions (CIN 3) within 3 years of infection (about 9% of women with other high-risk HPV types 4% of cases), 20% of women develop a high degree of cervical precancerous lesions within 10 years (about 7% of other high-risk HPVs).
