What is Human Papilloma Virus?


Uterine Cervix Cancer

The human papillomavirus (HPV) is a microorganism capable of producing lesions on the cervix, of which there are several types, so-called «low risk» and «high risk», some of which are associated with the development of cervical cancer.

It is very difficult to prevent transmission of HPV. Barrier contraceptive methods are only partially effective, since the virus can exist in most of the anogenital area (including areas that are not covered by male condoms) and can remain active for years.

While there is no treatment to eradicate HPV, in most cases the infection is referred to undetectable levels. In some women, however, HPV infection persists and evolves precancerous lesions, called dysplasias. Immunocompromised women may have high risk of persistent infection.

The detectable HPV infection is more common in young women, reaching 25% of the female population 30 years are positive high-risk HPV. In most cases HPV infection is eliminated by the immune system within 16 to 24 months. In over 30 percent of Mexican women HPV infection it is in the range of 10% -13%.

The cervical cancer usually takes many years to develop; Older women are the group at highest risk and which requires more control.

It is likely that many women infected with HPV develop mild dysplasia, most of which has not progress or regression, especially among women under 30 years.

Progression to precancerous lesions detectable or can take up to 10 years.

Women over 30 who have identified them moderate or severe precancerous lesions at high risk of developing cancer.
