Sen. Christopher Dodd is recovering from what his aides call a "successful" surgery for prostate cancer.
Dodd announced last month that he had been diagnosed with an early, treatable stage of cancer. He expects to return to a full Senate schedule at the end of August.
Dodd has said that the cancer will not affect his plans to seek a sixth term next year.
He is the chairman of the Senate Banking Committee and is playing a leading role in the effort to overhaul the nation's health care system.
