Which strains of hpv cause cancer




















Cervical cancer can be found early and even prevented with routine screening tests. The Pap test looks for changes in cervical cells caused by HPV infection. The HPV test looks for the infection itself. HPV can also cause cancer of the vulva , which is the outer part of the female genital organs. This cancer is much less common than cervical cancer.

Many vaginal pre-cancers also contain HPV, and these changes may be present for years before turning into cancer. If a pre-cancer is found, it can be treated, stopping cancer before it really starts. In men, HPV can cause cancer of the penis. Because almost all penile cancers start under the foreskin of the penis, they may be noticed early in the course of the disease. HPV can cause cancer of the anus in both men and women.

Screening tests for anal cancer are not routinely recommended for all people. This includes men who have sex with men, individuals who have had cervical cancer or vulvar cancer, anyone who is HIV-positive, and anyone who has had an organ transplant.

HPV is found in some mouth and throat cancers in men and women. This is true of both oncogenic and non-oncogenic HPV types. By age 50, at least 4 out of every 5 women will have been infected with HPV at one point in their lives. HPV is also very common in men, and often has no symptoms. Similarly, when high-risk HPV lingers and infects the cells of the vulva, vagina, penis, or anus, it can cause cell changes called precancers.

These cancers are much less common than cervical cancer. Much less is known about how many people with HPV will develop cancer in these areas. Skip directly to site content Skip directly to page options Skip directly to A-Z link. HPV and Cancer. Most types of HPV cause "common" warts.

These warts can grow anywhere on the body and are often found on the hands and feet. They are contagious and spread by touch, but they do not cause cancer. HPV is the most common sexually transmitted infection. Genital HPV can infect any part of the genital area, including the vulva, inside the vagina, or the penis.

It can also infect the anus and some areas of the head and neck. Some types of genital HPV cause warts that vary in size, shape, and number. These viruses rarely lead to cancer. They are known as low-risk HPV. Your body's immune system can often get rid of this infection. But some people have a lasting infection. Over time, the infection can turn normal cells into precancerous lesions or cancer. Cervical cancer.

HPV causes nearly all cervical cancers. However, most genital HPV infections will not cause cancer. Smoking can also raise the risk of cervical cancer in women with HPV. Cancer Treatment Research. Cancer Health Disparities. Childhood Cancers Research.
