All I had was a mouth ulcer. It wasn't even particularly painful, but then my cat started acting oddly - sniffing at my mouth, pressing her head under my chin. I went to see my GP and 3 weeks later was diagnosed with carcinoma.

Sadly, my cancer had been growing for months inside the muscle of my tongue. I'd had a few odd symptoms during that time but nothing that gave me any indication it was cancer. If I hadn't gone to the doc when I did I do wonder how long I'd have waited. I've heard the stories about animals sensing cancer and other illnesses but I never really believed until now!
