Oral Sex Link to Cancer

Oral sex can lead to oral cancers. Researchers have shown that the human papilloma virus, an extremely common sexually transmitted infection long been known to cause cervical cancers, can also cause mouth cancers. Fortunately, the risk of developing oral cancer is tiny. Only around 1 in 10,000 people develop tumours each year, and most cases are probably caused by smoking and drinking. The findings could help improve treatments of oral cancers, and vaccines that protect against HPV are already being developed
