“Cancer is a disease in which cells in the body grow out of control. Cancer is always named for the part of the body where it starts, even if it spreads to other body parts later.When the body’s immune system can’t get rid of an HPV infection with oncogenic HPV types, it can linger over time and turn normal cells into abnormal cells and then cancer. In general, HPV is thought to be responsible for more than 90% of anal and cervical cancers, about 70% of vaginal and vulvar cancers, and 60% of penile cancers. HPV is also very common in men, and often has no symptoms. About 10% of women with HPV infection on their cervix will develop long-lasting HPV infections that put them at risk for cervical cancer.All HPV vaccines protect against at least HPV types 16 and 18, which cause the greatest risk of cervical cancer. Each year in the United States, about 11,500 new cases of cervical cancer are diagnosed and about 4,000 women die of this cancer.”
