Men face higher risk of cancers linked to oral sex

Dr. D'Souza compared both men and women for her study and she concluded that, even if they both have the same number of sexual partners and perform both oral and normal sex, oral sex increased the risk of cancer in men only. Moreover, the study has also pointed out the fact that HPV infections can up the risk of throat cancer in men.

Men are more at risk of developing mouth and throat cancer linked to oral sex, which can spread human papillomavirus (HPV), one of the most common sexually transmitted infections, which according to the U.S. Centers for Disease Control and Prevention (CDC) affects more than 90 percent and 80 percent of sexually active men and women, respectively.

She said her research shows that youths are engaging in oral sex at increasingly young ages, compared to past generations. Among White men, middle aged men had the highest risk. The number of sexual partners does not seem to affect women's risk for these cancers and that women who have more vaginal sex partners appear to have lower risk for oral HPV infection.

Gypsyamber D'Souza, an epidemiology professor at the University of John Hopkins declared that approximately 2 out of 3 oral cancers that occur in the United States are caused by the HPV 16 strain of the human papillomavirus.

The number of cases of cancer linked to HPV has gone up in the recent years.

The research shows that, not only are men more likely than women to contract oral HPV infections, but that, once they are infected, men are less likely to fight off the infection, further contributing to the cancer risk.

Men who engage in oral sex with multiple sexual partners have a 22 percent change of developing mouth and throat cancer.

Although HPV infection is very common, most people are able to eliminate the virus in a few years. And the number of sexual partners is the same as in the case of the males. She said that the reason for this may be that women mount an immune response to HPV when they are first exposed vaginally, and this helps prevent them from contracting oral HPV infections. This allows them to build an immune response and they do not become infected with the virus orally. These cellular damages eventually lead to cancer.

This type of cancer has risen 225 percent in the last two decades.

New research suggests that women who have had many sexual partners are less likely to get oral cancer, meanwhile men who have had the same number of previous sexual partners are more likely to suffer from the disease.
