It would seem that oral sex causes throat cancer. This was stated by the John Hopkins University who has studied a sample of three hundred patients. The research found that those who change partner often has nine times more likely to get cancer of the throat and up to thirty-two who has had previous oral infections.
HPV, which is the main cause of the problem, it is transmitted more easily orally and its transmission rises naturally to the high number of partners, especially when faced with behavior or occasional sexual risk.
The analysis of saliva and some questions on family history and sexual behavior complete the picture: it seems that even oral sex can affect cancer risk than other risk behaviors such as alcohol and smoking.
