New Swedish research, to be published next year, will provide powerful evidence that oral sex can cause mouth cancer.
That is the conclusion of researchers who have proved what has long been suspected, that the human papilloma virus, HPV, can cause oral cancers. HPV is an extremely common sexually transmitted infection.
The study was conducted at the Malmo University Faculty of Odontology in southern Sweden.
The risk, however, is tiny. Only around 1 in 10,000 people develop oral cancer each year; and most cases are probably caused by two other popular recreational pursuits: smoking and drinking.
