Actor Michael Douglas says his throat cancer was not caused by years of heavy smoking and drinking—it was caused by a sexually transmitted disease contracted via oral sex. "Without wanting to get too specific, this particular cancer is caused by HPV [human papillomavirus], which actually comes about from cunnilingus," Douglas told the Guardian. "It's a sexually transmitted disease that causes cancer. And if you have it, cunnilingus is also the best cure for it."
A head and neck surgeon confirmed that cancer-causing HPV is a very real thing. "It has been established beyond reasonable doubt that the HPV type 16 is the causative agent in oropharyngeal cancer," he said. However, the doctor questioned Douglas' assertion that oral sex could also help cure the disease. "Maybe he thinks that more exposure to the virus will boost his immune system. But medically, that just doesn't make sense." (Read more Michael Douglas stories.)
