According to new research, Human Papillomavirus (HPV) may be responsible for the development of oral cancer in men to a greater extent than previously thought. Statistics show that in the past four decades, incidence of oral cancer caused by HPV has risen to a point where it now equals the incidence of oral cancer caused by alcohol and tobacco, widely regarded as the primary factors contributing to the development of oral and esophageal cancer.

If this trend continues, HPV will surpass alcohol and tobacco as the primary cause of oral cancer in men. Study co-author, Dr. Maura Gillison of Johns Hopkins University, said “We need to start having a discussion about those cancers other than cervical cancer that may be affected in a positive way by the vaccine…”

Gardasil was approved for use in girls in 2007, as a vaccine against HPV, one of the causes of cervical cancer. It has been reported that Merck & Co is considering applying for an FDA approval to administer the vaccine to boys, as well.
