When Michael Douglas mentioned in an interview that performing oral sex could be a risk factor for the type of throat cancer he had, his comments swept the Internet. Now the Behind the Candelabra star is issuing a clarification. His remarks did serve to raise awareness about HPV's role in a certain type of oral cancer, namely those classified as oropharyngeal cancer, a cancer that affects the back third of the tongue, the soft palate, the side and back walls of the throat and the tonsils. But experts say that the clarification was in order. "Oral sex doesn't cause oral cancer," says Dr. Maura Gillison
, a head and neck medical oncologist and professor at Ohio State University Comprehensive Cancer Center. "It's a means by which to acquire an infection that rarely causes cancer."
