A Stage IV diagnosis is not a small thing to absorb. There were moments of fear, moments of grief, and the overwhelming reality of treatment ahead. I won’t pretend it was easy — it wasn’t. But I held onto something that kept me moving forward: the belief that what I was going through could mean something for someone else.
Treatment for oral tongue cancer is intensive. It affects your ability to speak, to eat, to do the things most people take for granted every day. Recovery is slow, and some changes are lasting. But I came through it. And when I did, I knew I had work to do.
My story is not unique — and that’s exactly the problem. Thousands of Canadians are diagnosed with oral cancer every year, and many of them, like me, had symptoms that were present long before a diagnosis was made. Subtle symptoms. Easy-to-dismiss symptoms. A sore that didn’t heal. A feeling that something wasn’t quite right.
The gap between “something feels off” and “someone takes it seriously” can cost lives. I know that firsthand. So I developed the Two-Week Rule Initiative — a simple, clear message: if something in your mouth hasn’t healed in two weeks, it needs professional attention. No waiting. No assuming it will pass.
What I’m Doing About It
Today I work to get that message into dental offices, medical waiting rooms, and community spaces across Canada. I speak with healthcare professionals, connect with patients, and do everything I can to make sure the signs of oral cancer are recognized earlier — before a Stage IV diagnosis becomes someone’s reality. I am also writing Silent But Resilient, a memoir about my diagnosis, treatment, and recovery, and about what this experience taught me about the healthcare system, the human body, and the will to keep going.
If my story saves even one person from a late-stage diagnosis, this work is worth everything.
If you have a persistent oral change that hasn’t resolved in two weeks — please don’t wait. See a dental or medical professional and ask to be assessed.
