Which strain of hpv causes cervical cancer




















The 14 most cancer-causing HPV types include types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and However, not all infections with HPV 16 or 18 do progress to cancer. In addition, HPV 16 is strongly associated with anal cancer and throat cancer.

Current research indicates that high-risk HPV changes the host human cell but its growth needs additional triggers to cause cancer. Most HPV infections are transient and thought to clear naturally before they cause any health problems. HPV Strains. It is critically important to study cervical cancer in African populations, and to compare the results obtained to other HPV-associated cancers, such as head and neck cancers, which are being observed with increasing frequency in western populations.

Oral cancer. HPV can cause cancer of the mouth and tongue. It can also cause cancer of the oropharynx. This is the middle part of the throat, from the tonsils to the tip of the voice box.

These HPV-related cancers are rising. Other cancers. HPV is also linked to less common cancers. They include anal , penile , vaginal , and vulvar cancers. Many types of HPV have no symptoms. For women who are sexually active, there is an HPV screening test that can detect the strains of HPV most commonly linked to cervical cancer. During this test, a trained health care professional takes a sample of cells from a woman's cervix.

This sample is tested by a pathologist. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease. HPV testing can be done alone or with a Pap test. Pap tests look for any abnormal changes to the sample of cells taken from the cervix. HPV 11 can also cause changes to the cervix. Genital warts look like cauliflower-shaped bumps on your genitalia. They usually show up a few weeks or months after exposure from a sexual partner who has HPV.

You can apply these medications directly to your genital warts. It causes 50 percent of cervical cancers worldwide. HPV 16 and HPV 18 are together responsible for approximately 70 percent of all cervical cancers worldwide. HPV testing can be performed for women with a Pap test commonly known as a Pap smear , which is a screening test for cervical cancer.

If present, the test can determine whether the HPV is a low- or a high-risk type. This is because many women will have some strain of HPV by that age. Most of these will clear spontaneously without intervention.

It does mean that you could develop cervical cancer in the future, especially if you have a high-risk type of HPV.
