Screen veteran Michael Douglas has revealed that it took his doctors nine months to realise that the mass in his throat was cancer.
Speaking during an interview with New York magazine the actor, who will play pianist Liberace in the HBO biopic Behind the Candelabra, said he was initially prescribed antibiotics to deal with his pain.
"I knew something was wrong," he said. "My tooth was really sore, and I thought I had an infection".
It wasn't until 2010 that another consultant confirmed the actor had cancer. "Two days later, after the biopsy, the doctor called and said I had to come in.
"He told it me it was stage-four cancer. I said, 'Stage four. Jesus.' And that was that.
"After complaining for nine months and them not finding anything, and then they told me I was stage four? That was a big day."
The Wall Street star, who is married to Catherine Zeta-Jones and has two children with the Welsh actress, is now in remission from the disease and is making his Hollywood comeback playing flamboyant pianist Liberace.
Michael's wife Catherine has also been back on screen of late, starring alongside Jude Law in the Steven Soderbergh-directed thriller Side Effects.
The Welsh star has openly discussed her own struggles with Bipolar disorder and is currently seeking additional treatment for the condition, which is associated with mood swings and extended periods of depression.
"Catherine has proactively checked into a healthcare facility," her rep told People magazine at the end of April.
A friend said her stay at the clinic was "no big problem" adding, "This was just a good time to do it. She is between projects.
"This has always been part of the plan. She would manage her health. She is vigilant about it."
