1 in 4 men have genital HPV infections that cause or are linked to cancer

Nearly half of all men in the US have some type of genital human papillomavirus infection—and about 25 percent have a type linked to cancer, according to a study appearing Thursday in JAMA Oncology.

The study is the first to look at the prevalence of HPV among American men. Much of the past attention paid to HPV has focused on women, because the virus is the cause of nearly every case of cervical cancer in the US. For this reason, health experts have been recommending since 2006 that girls and young women get vaccinated against HPV.

Experts updated that recommendation to include boys and young men in 2011, but the new study shows that few are actually getting those shots—just 10 percent were vaccinated. But with the new prevalence data, the authors suggest that vaccinating men may not only prevent thousands of cancer cases, but it could also be key to stamping out cancer causing-HPV transmission overall.
