Sen. Chris Dodd is expected to announce Friday that he will be treated for early-stage prostate cancer.

(CNN) – Sen. Christopher Dodd announced Friday that he has an early form of prostate cancer, but said he is going to be fine.

"I feel fine; I'm going to be fine. We caught this early," he said at a news conference with his wife, Jackie Clegg Dodd.

He will undergo surgery after the Senate adjourns next week, Dodd said.

Dodd, 65, is expected to face a tough re-election campaign in 2010. He stated emphatically Friday he still plans to run.

"The condition was caught extremely early," said a source close to Dodd, who added that the procedure is routine, and the senator's health "is otherwise superb."

"This in no way whatsoever affects his re-election plans," said the source.

UPDATE: Dodd sent his supporters a message Friday afternoon confirming the report.
