A-list celebrities seem to be opening up about their medical issues.
Several weeks ago, actress Angelina Jolie wrote a thoughtful essay for the New York Times about her difficult decision to undergo a double mastectomy.
And now, in a less moving but still very personal announcement, Michael Douglas has implied to a Guardian reporter that he performs a lot of oral sex on his wife.
In an interview with the Guardian, Douglas was asked about the throat cancer that he suffered from back in 2010. Douglas explained that he got the cancer from HPV, or human papillomavirus, an extremely common sexually transmitted disease.
As for the HPV, he says he got that by performing oral sex. "This particular cancer is caused by HPV, which actually comes about from cunnilingus," he said.
Perhaps not wanting to make it look like he was blaming his wife — fellow actor Catherine Zeta-Jones — for the cancer, he then added: "And if you have [throat cancer], cunnilingus is also the best cure for it."
It's true that HPV does cause throat cancer, as NBC points out in its news article titled, "Michael Douglas is right, HPV can cause throat cancer."
But is cunnilingus to blame? Experts simply don't know the answer to that question because it hasn't been studied enough. The UK's National Health Service explains that "there is very little research" that compares the risks of performing cunnilingus vs. performing fellatio when it comes to contracting HPV.
However, researchers do know that HPV-related throat cancer is twice as common in men than in women, and is more common in heterosexual men than in homosexual men. This suggests that cunnilingus is a bigger risk factor for contracting HPV than fellatio, a stark contradiction to most STDs in which fellatio is usually the bigger risk.
So Douglas can't prove that he's right about the exact cause of his HPV, but research suggests that he might be.
