There are many different strains of the virus, each identified with a number. HPV 16 and 18 are high-risk types that are known to significantly increase the risk of cervical, vaginal and vulvar cancer in women, as well as penile cancer in men. The strains can also cause anal cancer and throat cancer in men and women. HPV strains 16 and 18 are known to cause cervical cancer.
HPV infection is very common. In most people, the body is able to eliminate the infection on its own. But sometimes, the infection doesn't go away. A chronic or long-term infection, especially when caused by certain high-risk types of HPV, can cause cancer over time.
The HPV test is a screening test for cervical cancer, but the test doesn't tell if you have cancer. Instead, the test detects the presence of HPV, the virus that causes cervical cancer, in the system. Certain types of HPV, including types 16 and 18, increase the risk of cervical cancer.

(HPV) strains 16 and 18 are the two most common strains of HPV that lead to genital cancer.HPV is the most common sexually transmitted disease, producing more than fourteen million cases per year in the United States alone. If left untreated, HPV carries a high risk of cancer of the cervix, vagina, vulva, anus and penis. In 1983 and 1984 in Germany, doctor Harald zur Hausen discovered that two strains of HPV, HPV-16 and HPV-18, caused cervical cancer in women. At the beginning of the 21st century, pharmaceutical companies Merck & Co.
And GlaxoSmithKline created HPV vaccines that protect against HPV-16 and HPV-18, which have reduced the number of HPV infections by fifty-six percent in the U.S. UU. The discovery of HPV strains 16 and 18 allowed doctors to test for cancer-causing cell populations using the Pap smear, a diagnostic tool that collects cells from a woman's cervix to identify cancerous cases of HPV infection. By identifying cancerous strains of HPV-16 and HPV-18 and using preventive measures such as Pap smears and HPV vaccines, scientists and doctors have reduced rates of cervical and other HPV-related cancers.
While there are more than 100 types of HPV, only a dozen of them are associated with cervical disease. Genital warts are a low-risk form of HPV and do not cause cancer. We all hope that the discomfort is over after we had our Pap and HPV tests. So, hearing that you have tested positive for HPV can be a shock.
Human papillomavirus (HPV) is a sexually transmitted infection (STI), also known as sexually transmitted disease (STD). Cervical dysplasia, in which cell changes occur in the cervix at the opening of the uterus, is a more common outcome of HPV infection. When talking to your partner about your diagnosis, remember that 80% of people will have HPV at some point in their lives. This means that almost anyone who is sexually active will get at least one type of HPV during their lifetime.
HPV is spread through sexual contact and is very common in young people. Often, the test results will be positive. Infection with high-risk types of HPV (HPV-RA) that are not eliminated by the immune system can cause cervical cancer and a significant proportion of cancers of the anus, oropharynx, vagina, vulva, and penis. HPV is very common in women under 30 and most of these women will fight the virus within a few years and will never experience health problems as a result of HPV.
With its updated guidelines, WHO now encourages countries to use HPV testing for cervical screening, including HPV DNA and mRNA testing. If you get HPV 6 or HPV 11, your doctor may prescribe medications such as imiquimod (Aldara, Zyclara) or podofilox (Condylox). Condoms (“gums”) provide some protection against HPV, but do not completely prevent infection. If you test positive for HPV, your doctor has detected one or more high-risk strains of the virus on the cervical Pap test.
Cervarix is a vaccine that only protects against HPV strains 16 and 18, which mainly cause cervical cancer. In the samples, he first identified the DNA of HPV strains 6 and 11, two common types of HPV that cause genital warts. Persistent HPV infections occur when HPV DNA successfully survives in the body, leading to long-term chronic infections. .
