Catherine Zeta Jones - Catherine Zeta-Jones Reveals Diagnosis Fury

Catherine Zeta-Jones was "furious" doctors failed to spot her husband's throat cancer.

The 40-year-old actress has spoken out about her frustration after Michael Douglas' repeated complaints of throat and ear pain did not lead to a walnut-sized tumour being discovered at the base of his tongue until three weeks ago.

She said: "It makes me furious they didn't detect it earlier. He sought every option and nothing was found."

However, the brunette beauty - who has 10-year-old son Dylan and seven-year-old daughter Carys with the actor - admits she was unsurprised when he was finally diagnosed with cancer.

She told People magazine: "It wasn't a huge shock. I knew something was up. He knew something was up."

The 'Wall Street: Money Never Sleeps' star - who also has 31-year-old son Cameron with ex-wife Diandra - admitted earlier this week he had been having throat problems for a long time before his diagnosis.

He said: "It had been bothering me for a while. I went through a litany of doctors and tests."

However, he was understanding about the length of time doctors took to discover his condition.

He said: "These things sometimes just don't show up."

The 65-year-old star - who is currently undergoing chemotherapy and radiation treatment - has previously revealed he has an 80 per cent chance of surviving cancer.
