Can Oral Sex Cause Cancer, Micheal Douglas says "yes"

Micheal Douglas is a well known Hollywood star. he is famous not only for his histrionic ability but for marrying a woman much younger to him , the beautiful Catherine Zeta Jones. Micheal is diagonized with throat cancer. I think he has been cured now, but the illness has led to estrangement with his wife and divorce is on the cards. Douglas has made a bizarre statement that his throat cancer was due to excessive oral sex. No doctor has corroborated this story, but Micheal talks from personal experience.

I and others can comment on this from personal experience. I wonder how many will agree with Micheal Douglas. Oral sex is man's way of paying homage to teh woman he loves. it is a form of worship. Micheal must have been fond of it, to talk so surely. But I suppose all this can be taken with a pinch of salt. At the same time the confession of a 68 year old man cannot be dismissed out of hand. However none of the sex manuals talk of this bizarre claim of Micheal Douglas. Do you my friends agree with him ?
