"Smoking prevalence has dropped dramatically, and, likewise, most head and neck cancers have declined in incidence. Cancers at the base of the tongue and tonsil are increasing or have remained stagnant. We're not seeing the reduction in incidence that we would have expected," said study author Dr. Erich Sturgis, an associate professor of head and neck surgery and epidemiology at the University of Texas M.D. Anderson Cancer Center, in Houston.

The study authors suspect the reason may be orally transmitted HPV infections.

"Just as cervical cancer is the outcome of a sexually transmitted disease, as are most anal and penile cancers, people need to be aware that they can get throat or tongue cancer as the consequence of a sexually transmitted disease," said Sturgis. "Oral sex can't be considered safe sex."

... ... HAHAHAHA! Wow.
