Washington Secretary of State Kim Wyman is cancer-free.

Wyman said in a news release Thursday that she responded well to the treatment and her doctor says there's no evidence of a tumor.

“At my eight-week post-radiation check-up, the doctor found no evidence of the tumor. There will be follow-up tests to confirm that all cancer cells are dead, but this was the diagnosis we were hoping for,” Wyman said.

She was diagnosed with colon cancer in March.

Wyman also thanked everyone who provided encouragement, support and prayers over the last few months.
