Smoking is commonly known as main cause of throat cancer. But recent research found that a virus that spread during oral sex is now the main cause of throat cancer.
Scientists who conducted the study shows, Human Papillomavirus (HPV) that spread during unprotected sex can cause mouth cancer which potentially deadly virus in recent decades.
Therefore, now physicians also urge teenage boys to undergo HPV vaccination as girls, to stop the spread of the HPV virus.
According to Prof. Dr. Maura Gillison of Ohio State University in Columbus, although scientific evidence has not fully know whether the vaccine can protect people from HPV infection that cause cancer, but so far the vaccine has been proven effective for preventing virus infection.
In the UK, the incidence of throat cancer increased significantly, while in the U.S. incidence of oral cancer associated with HPV was doubled in the last 20 years.
Prof. Dr. Gillison said, someone who infected with HPV 16, a strains of HPV virus associated with oral cancer, had a 14 times increased risk of developing oropharyngeal cancer – a cancer of the tongue, throat or tonsils.
“The most strongly associated with oral HPV infection is the number of sexual partners. The more sex partners you have, the more likely you are infected with oral HPV,” explained Prof. Dr. Gillison.
A study conducted in the US on 300 participants showed that a person with more than six sexual partners is nine times more likely to develop this disease. On the other hand, people who had infected with oral HPV infection, 32 times are more likely to develop cancer.
