LOS ANGELES: Michael Douglas said he would win a Nobel prize if he knew exactly what caused his throat cancer, in fresh comments Tuesday after a dispute with a British newspaper over an interview he gave.

The “Fatal Attraction” star, whose spokesman already denied he blamed his throat cancer specifically on the human papillomavirus (HPV), also said that, regardless, he was happy to raise awareness about causes of the killer disease.

“I never expected to become a poster boy for head and neck cancer,” Douglas said in comments issued by a representative.

“But, if after what started out as trying to answer a couple of questions about the suspected sources of this disease results in opening up discussion and furthering public awareness, then I’ll stand by that.”

In an interview with Britain’s Guardian newspaper, Douglas, who stars in the just-released biopic of flamboyant entertainer Liberace, “Behind The Candelabra,” said his cancer was caused by the HPV.
