Sen. Christopher J. Dodd (D-Conn.) underwent surgery for prostate cancer and was recuperating at a New York hospital. Dr. Peter Scardino of Memorial Sloan-Kettering Cancer Center said the surgery was successful and Dodd was resting comfortably.
"It is anticipated that he will be able to return to full activity within a few weeks," Scardino said in a statement released by Dodd's office.
Dodd, 65, is expected to remain at the hospital for a few days before returning home to Connecticut.
The five-term Democrat announced last month that he had been diagnosed with an early, treatable stage of cancer.
