BBC NEWS | Health | Oral sex linked to throat cancer
A virus contracted through oral sex is the cause of some throat cancers, say US scientists.
HPV infection was found to be a much stronger risk factor than tobacco or alcohol use, the Johns Hopkins University study of 300 people found.
The New England Journal of Medicine study said the risk was almost nine times higher for people who reported oral sex with more than six partners.
