A new study shows the HPV vaccine may lower the risk of oral cancer in men.
In the study, no men who had received at least one dose were later found to have infections of HPV strains linked to cancer, but more than 2 percent of unvaccinated men had them.
Results were released by the American Society of Clinical Oncology.
HPV is being linked to 70 percent of cancers in the mouth and back of the throat. They are four times more prevalent in men than women.
The three-dose vaccine is recommended for males and females ages 9 to 26, but the rate of people actually getting the shots is low.
