(WTVM/AP) - Michael Douglas' publicist is backing away from a report about what caused his throat cancer.
The Guardian reports that in an interview Douglas revealed that his throat cancer was caused by contracting the Human Papillamavirus through oral sex.
His publicist says Douglas never specifically pointed to HPV as the cause, but says the actor simply stated it was one of many possible causes.
The 68 year old was diagnosed with cancer in 2010.
He is now cancer-free after extensive chemotherapy.
