A study published in yesterday's Journal of Clinical Oncology reveals that as many as 72 percent of throat tumors in men may be linked to the human papillomavirus, commonly known as HPV. The researchers hypothesize that the virus spreads predominately via oral sex, and that it may already account for more cases of throat cancer than smoking.
"The burden of cancer caused by HPV is going to shift from women to men in this decade," said Maura Gillison, an oncologist at Ohio State University and lead author of the study. "What we believe is happening is that the number of sexual partners and exposure to HPV has risen over that same time period."Here's the study's abstract.
