So far, the most widely regarded cigarettes cause throat cancer. But recent findings indicate that the virus is spread through oral sex is now a cause
primary cancer of the throat.
Scientists who conducted the study shows that the Human Papilloma Virus (HPV) is spread during unprotected sex can cause mouth cancer is potentially lethal in recent decades.
To that end, physicians now have many calling for the boys also perform HPV vaccination as girls, to stop the spread of the HPV virus.
"HPV is transmitted through sexual intercourse is a cause larger than some oral cancer than tobacco," explained Prof. Maura Gillison of Ohio State University in Columbus, as reported by Dailymail on Monday (2/21/2011).
According to Prof. Gillison, although scientific evidence has not fully know whether the vaccine can protect people from infection with HPV that cause cancer, but so far has proven highly effective vaccine. HPV vaccine 90 percent effective in preventing viral infection which also causes cervical cancer in women.
Physicians increasingly worried that the virus is spread through sexual activity is behind the increase in cancer.
In England the incidence of throat cancer increased sharply, while in the U.S. incidence of oral cancer associated with HPV be doubled in the last 20 years.
According to Prof. Gillison, in Sweden in the 1970s, about a quarter of thyroid cancer associated with HPV, but in the mid 2000s to 90 percent figure.
"That's the most interesting data, in a population with an increased cancer tonsular or oropharynx cancer incidence we see in several places around the world, may be caused by HPV," she said.
Prof. Dr. Gillison said, someone who is infected with HPV 16, the strains of HPV virus associated with oral cancer, increasing the risk to 14 times lipta had oropharyngeal cancer (cancer of the tongue, throat or tonsils).
"The most strongly associated with oral HPV infection is the number of sexual partners who perform oral sex activity. The more sex partners you have, the more likely you are infected with oral HPV," explained Prof. Dr. Gillison.
Last year a study at Johns Hopkins University found that HPV caused a greater risk of cancer than cigarettes or alcohol.
American study on 300 participants showed that people with more than six sexual partners, nearly nine times more at risk of contracting the disease
this. While people who have had prior oral HPV infection, 32 times more likely to develop cancer.
