Catherina Zeta-Jones Angry at Doctors Over Husband's Cancer Diagnosis

NEW YORK (CBS) Catherine Zeta-Jones says she's angry that doctor's didn't discover husband Michael Douglas' cancer diagnosis sooner.

Douglas is currently undergoing radiation and chemotherapy to treat a walnut-sized tumor at the base of his tongue.

The actor said he spent months seeking attention for persistent ear and throat pain, but that no cause was found until he received the cancer diagnosis in early August.

"It makes me furious they didn't detect it earlier," Zeta-Jones told People magazine in an interview published in Friday's issue. "He sought every option and nothing was found."

Douglas and Zeta-Jones have been married for 10 years and have two children together, Dylan, 10, and Carys, 7.

The actor announced his diagnosis on August 16.

Zeta-Jones told the magazine that she struggles with watching her husband become fatigued due to the radiation and chemotherapy, which Douglas said "really knocks you out."

"I know maybe I should be stronger, but emotionally I just don't want to see that," she said, later adding, "The hardest part is seeing his fatigue, because Michael is never tired."

In his first appearance following the announcement of his diagnosis, Douglas told "Late Show" host David Letterman on Tuesday that while his disease was late "stage four," the cancer remains above the neck and that means expectations are good, with an 80 percent or better chance of recovery.
