HARRISBURG (AP) – PA U.S. Sen. Bob Casey will undergo surgery for prostate cancer, but is expected to make a full recovery. The 62-year-old Democrat said in a statement that he was diagnosed last month. “While this news came as a shock, I can report that I have an excellent prognosis, as well as the benefit of exceptional medical care and the unwavering support of my family.” He said he will undergo surgery in the coming months and is confident that treatment will allow him to continue working in the Senate “with minimal disruption.” Casey, serving his third term, has not said whether he will run for a fourth term in 2024. At 16 years in the Senate, Casey is already the longest-serving Democrat U.S. senator in PA history.
