The types of sexually transmitted HPV fall into two categories, low risk and high risk
HPV infection is common: Almost all sexually active people become infected with HPV
Most HPV infections don't cause cancer: Your immune system usually controls HPV infections, so they don't cause cancer
Persistent high-risk HPV infection can lead to cancer: Sometimes HPV infection is not successfully controlled by the
HPV vaccination can prevent cancer: The HPV vaccine protects against infection with HPV types of diseases, preventing many cases of HPV-related cancers and genital warts
Cancer caused by HPV infection
HpV infection at high risk for long-term infection can lead to cancers of parts of the body with HPV-infected cells, such as the cervix, oropharynx (the part of the throat at the back of the mouth, including the soft palate, basal part) and tonsils, anus, rectum, penis, vagina and vulva
How does HPV spread?
HPV is transmitted
Can an HPV infection cause symptoms?
High-risk HPV infection does not cause symptoms
HPV vaccination is used to prevent HPV infection
HPV vaccination provides strong protection against new HPV infections, but this vaccine does not treat HPV infections or diseases

Screening tests are tests used to check for disease when there are no symptoms
Screening for cervical cancer
cervical cancer screening test:
These screening ages and intervals are appropriate for most women:
Screen for other HPV-related cancers
There are currently no FDA-approved tests
Treatment of cellular changes caused by HPV infection
Although HPV infection itself cannot be treated, there are treatments

In women with a high risk of HPV infection with cervical cells, there are several factors that increase the duration of infection and lead to the chance of cervical precancerous cells:
