HPV a cause of oropharyngeal cancer in US youth
The sexually transmitted human papillomavirus (HPV) may be behind the sharp rise in cases of throat and mouth cancers among young American adults, researchers say.
HPV, which can cause genital and anal warts, is the most commonly transmitted sexual infection in the United States. Usually, the immune system clears the infection, but in some cases the virus persists in the body. And persistent infection with certain HPV strains can eventually lead to cancer – with cervical cancer the best known.
