ST. PAUL — Minnesota Gov. Mark Dayton is recovering from surgery to treat a recent prostate cancer diagnosis.

His deputy chief of staff, Linden Zakula, said Dayton’s surgery went as planned Thursday, with the procedure ending about 11:30 a.m. Zakula said the governor is resting comfortably at the Mayo Clinic in Rochester.

Dayton revealed his diagnosis just a day after he collapsed during his State of the State address last month. His doctors have said the cancer was caught early and is treatable.

The Democratic governor expected to spend the night in the hospital but will return to his normal work schedule next week.

The cancer diagnosis is the latest health setback for Dayton. The 70-year-old governor has had several hip and back surgeries during his six years in office.
