A wide variety of hpv types can cause genital warts, but types 6 and 11 together account for about 90 of all cases.
Immunological control is hpv type-specific, meaning an individual may become resistant to one hpv type while remaining susceptible to other types. In one study, infection by hpv types 2, 27, and 57 was found in people with warts, while infection by hpv types 1, 2, 63, and 27 was found in people with clinically normal skin. 21 Types of warts include: Common warts are usually found on the hands and feet, but can also occur in other areas, such as the elbows or knees. Common warts have a characteristic cauliflower -like surface and are typically slightly raised above the surrounding skin. Cutaneous hpv types can cause genital warts but are not associated with the development of cancer.

About 10 of adults also suffer from recurring skin warts. Citation needed All hpvs are believed to be capable of establishing long-term "latent" infections in small numbers of stem cells present in the skin. Although these latent infections may never be fully eradicated, immunological control is thought to block the appearance of symptoms such as warts.
3 to be most effective, they should be used before an infection occurs and are therefore recommended between the ages of nine and. 1 Cervical cancer screening, such as with the papanicolaou test (pap) or looking at the cervix after using acetic acid, can detect early cancer or abnormal cells that may develop into cancer. 1 This allows for early treatment which results in better outcomes. 1 Screening has reduced both the number and deaths from cervical cancer in the developed world. 10 Warts can be removed by freezing. 4 hpv is the most common sexually transmitted infection globally.

lead to precancerous lesions. If untreated, these lesions may progress to cervical cancer, but this progression usually takes many years. Symptoms of cervical cancer tend to appear only after the cancer has reached an advanced stage and may include: irregular, intermenstrual (between periods) or abnormal vaginal bleeding after sexual intercourse; back, leg or pelvic pain; fatigue, weight loss, loss of appetite; vaginal discomfort or odourous. More severe symptoms may arise at advanced stages. How hpv infection leads to cervical cancer. Although most hpv infections clear up on their own and most pre-cancerous lesions resolve spontaneously, there is a risk for all women that hpv infection may become chronic and pre-cancerous lesions progress to invasive cervical cancer. It takes 15 to 20 years for cervical cancer to develop in women with normal immune systems.
A small proportion of infections with certain types of hpv can persist and progress to cancer. Cervical cancer is by far the most common hpv-related disease. Nearly all cases of cervical cancer can be attributable to hpv infection. Though data on anogenital cancers other than cancer of the cervix are limited, there is an increasing body of evidence linking hpv with cancers of the anus, vulva, vagina, and penis. Although these cancers are less frequent than cancer of the cervix, their association with hpv make them potentially preventable using similar primary prevention strategies as those for cervical cancer. Non-cancer causing types of hpv (especially types 6 and 11) can cause genital warts and respiratory papillomatosis (a disease in which tumours grow in the air passages leading from the nose and mouth into the lungs).

The peak time for acquiring infection for both women and men is shortly after becoming sexually active. Hpv is sexually transmitted, but penetrative sex is not required for transmission. Skin-to-skin genital contact is a well-recognized mode of transmission. There are many types of hpv, and many do not cause problems. Hpv infections usually clear afhaalbericht up without any intervention within a few months after acquisition, and about 90 clear within 2 years.
