Mayo Clinic: Tests show Gov. Dayton’s prostate cancer is ‘treatable and curable’

He's deciding on what type of treatment he'll get.

Gov. Mark Dayton's prostate cancer was caught early, so it's treatable, the Mayo Clinic says.

The governor revealed last month he was diagnosed with prostate cancer, but didn't say much about the course of treatment because he hadn't met with his doctors at the Mayo Clinic yet.

He went there this week for scheduled appointment and had "extensive diagnostic tests" done. They showed no signs that the prostate cancer had spread beyond the prostate, Linden Zakula, Dayton's deputy chief of staff, said in an email statement Thursday.

The Mayo Clinic says the cancer "was caught early and is localized, treatable and curable." Dayton is now considering two treatment options – surgery or radiation – and when he makes his decision in the next several days, his staff will let people know, Zakula said.

When announcing his cancer, Dayton stressed he's committed to finishing his term as governor. And the Mayo Clinic said Thursday he "should be able to carry on his duties serving the citizens of Minnesota without significant interruption."

Prostate cancer

Prostate cancer is one of the most common types of cancer for men, the Mayo Clinic says. How serious it is can vary – some grow slowly and stay part of the prostate gland, and don’t cause much harm; others can grow aggressively and spread quickly.

When it’s detected early, the cancer is more treatable.

The American Cancer Society says there are expected to be about 161,360 new cases of prostate cancer in the U.S. this year – resulting in about 26,730 deaths. About one in every seven men will be diagnosed with prostate cancer in their lifetime, the group says. It generally develops in older men.
