You are referring to the latest news item, where English actor, Michael Douglas who is married to actress Catherine Zeta-Jones, claimed that his throat cancer was caused by HPV (Human Papillomavirus) which is transmitted through oral sex.
However the risk of developing head and neck cancers for people whose partners have HPV related cancer is very low. Throat cancers are normally caused by smoking, where the risk is 20% more than non-smokers or by heavy chronic alcohol consumption or those who suffer frequent heartburn.
It has been shown that men who have sex with men had almost 67% chance of contracting the virus and hence increase the risk of having cancer caused by the virus. STIs are preventable and most are curable, but since most STIs have no symptoms, testing is necessary to confirm its existence.
