Sen. Bill Nelson announced Thursday that he has prostate cancer and will have surgery on Monday.
The cancer was discovered early during a routine medical exam, Nelson's office said in a statement. Extensive scans showed no evidence that the cancer had spread.
The 72-year-old Democrat said the diagnosis does not affect his plan to run for re-election in 2018. He said he had no symptoms.
"I've been blessed with good health, which has allowed me the great privilege of public service, and I look forward to continuing serving our country and Florida," Nelson said.
