The 54-year-old American told Golf Channel the cancer was discovered during an appointment related to kidney stones.

“(The doctor said) it doesn’t look like any stones are in there. But unfortunately, you have bladder cancer,” Daly said.

“After I did the CT I was fixing to sip on my Diet Coke I got from McDonald’s and he said, ‘Don’t drink anything. We have to get you back in here and get this cancer out of you.’”

Daly underwent surgery to remove the cancer but said there was an 85% chance it could return, which would require more surgery.

“Luckily for me they caught it early, but bladder cancer is something that I don’t know all the details,” he said. “But it doesn’t look like it may go away. We will just see what happens. Maybe there’s a miracle.”

Daly told the website that he plans on changing two of his more unhealthy habits as he tries to fight the disease.

“I’m cutting way, way back on the Diet Coke and counting minutes before I can have a cigarette. I’m trying to quit smoking,” Daly said. “The doctors aren’t saying it’s too late. Unfortunately, it’s a cancer that keeps coming back. But I’m going to listen to them, and I’m going to try and quit smoking.

“If it comes back, it comes back. Six months to a year, if it doesn’t go away, I’m going to live my life. I’m gonna have some fun…. Well you know what, I always tell people I’ve lived one hell of a life. No matter what happens, I’m not scared to die or anything,

Daly, a five-time winner on the PGA Tour, won his two majors at the PGA Championship in 1991 and the Open in 1995.
