Keenan wasn't immediately sure if he wanted to go public with his disease, but he said the doctors at Sunnybrook urged him to tell his story in order to spread awareness. He started to do so in an article posted on TSN.ca on Tuesday.
"They encouraged me to go public, to use whatever platforms I could to help build awareness because they said men just don't talk about issues like this as women do," Keenan said. "I thought about it and I said, 'If I can turn a negative into a positive, I'd be happy to tell my story.' That's why I made the decision to go public, to just try to build awareness and be an advocate of an annual checkup, which is a simple blood test to monitor your prostate or any other health issues you might have."
Keenan's cancer was found through blood tests he has been getting annually since he was 45 years old. He said his prostate-specific antigen (PSA) level had always been normal, but this year it spiked.
"So the doctor said we should get you tested, and that includes biopsies to see what's going on," Keenan said. "It doesn't necessarily mean that you do have cancer, but it's a warning. So I did have the biopsies done and they discovered cancer in my prostate.
"Shock is a strong word, so I would say I was more surprised because my levels had been great."
Keenan visited doctors in the United States and Canada to seek opinions and learn of his options. He eventually chose brachytherapy.
"It's a sneaky disease because I have all kinds of energy and had all kinds of energy before," Keenan said. "I had no idea. That's why I was surprised. I've got a pretty high level of drive in me, and I didn't have any symptoms whatsoever before. Even the day after, or the day of [the procedure], I said, 'Are you sure you operated on me because I don't feel anything, I have no pain.' "
