Country singer Wade Hayes is recovering from surgery to treat cancer. Roughstock reported the news via Twitter earlier on Friday afternoon, saying that he was diagnosed with stage IV colon cancer. The singer was a hitmaker in the late ’90s and scored five Top 5 hits, including ‘Old Enough to Know Better,’ which went to No. 1.

Just last year, Hayes performed at the the Stars Go Blue for Colon Cancer event in Nashville. The event was organized by Nashville guitarist Charlie Kelley, who is the husband of GAC host Nan Kelley. Both are cancer survivors, with Charlie fighting off colon cancer in 2008. At the time, Hayes talked about about how important it was for him to support this event.

“I feel like any time I can help with cancer research [I will], because this whole world is weird and you never know when you might need help down the road,” he told Nashville County Club. “That may sound hokey to you, but that’s the way I feel about it and I’m glad to be here.” At the time, he admitted that a close family member was also diagnosed with terminal colon cancer.

Hayes’ Facebook and Twitter pages have yet to give updates on his condition, but fans who previously heard the news have been leaving supportive words since before Thanksgiving. The only indication from the singer that something is wrong comes in the form of a recent cancellation announcement: “Due to circumstances beyond control, the November 30th show at the Fiddle & Steel Guitar Bar in Printer’s Alley has been cancelled.”
