Jason Mendelsohn had been married for close to 20 years and was happily raising three kids when he noticed the painless lump on his neck while shaving three years ago.
Within days, he had been diagnosed with a deadly form of cancer caused by a virus that he probably caught while in college, decades before.
Mendelsohn, now 48, is the classic victim of head and neck cancer caused by HPV, the human papillomavirus. A new study out this week shows there’s a silent epidemic of HPV-related cancers among men.
A team at the University of Florida, Baylor College of Medicine and elsewhere found that 11.5 percent of U.S. men were actively infected with oral HPV between 2011 and 2014, and 3 percent of women were. That adds up to 11 million men and 3 million women, the researchers report in the Annals of Internal Medicine.
