Oral Sex Cause Cancer

Be careful with oral sex. Scientists in the United States says there is a strong link between oral sex and cancer. They are now trying to uncover why the human papillomavirus causes an increase in oral cancer cases in white men in the country.

The evidence on the relation of oral cancer and oral sex have long expressed to the researchers. Even experts find oral cancer caused by infection of human papillomavirus (HPV) is now more prevalent than tobacco use. In the U.S., between the years 1974-2007 has been an increase in oral cancer cases up to 225 percent, the majority of the white men.

"When compared with those who received oral infection or not, the biggest risk factor is the number of pairs of oral sex. The more the number of pairs, the higher the risk of developing cancer," said Maura Gllison from Ohio State University.

Previous studies mentioned, someone who had oral sex with six or more partners in his life has cancer risk 18 times higher than those of their partner less than six people.

One of the things that remains a mystery is why the increase in cases of oral cancer was found more often in white men. It takes a long time to answer it. However, experts believe the technology to detect HPV that have been used in the field of cervical cancer will help.

Currently there are 150 known different HPV types and 40 types of which can lead to sexually transmitted diseases. Some of them cause genital warts and the rest can increase the risk of cancer of the mouth, anal, vaginal, and penile.
