Bryant Gumbel

Bryant Gumbel underwent cancer surgery two months ago to remove a malignant tumor in his lung, he announced on Tuesday's Live with Regis and Kelly.

Gumbel, who filled in for Regis Philbin, made the announcement after telling Kelly Ripa he could not dance due to the surgery and a "note from my doctor."

"They opened up my chest. They took a malignant tumor, part of my lung and some other goodies," he said. "The pathology on most of the stuff came back benign, but enough aggressive cells had escaped the tumor that it warranted some treatment."

The Real Sports host said he told few people about the treatment and even kept it from his Real Sports staff. "We told my family, obviously," he said.

Gumbel, 61, is scheduled to see his surgeon next week.

"I'm OK for the time being," he said. "I'm hoping they greenlight me to play golf again."
