Everyone laughs when I tell how mine was found. We had just ourchased a RV and we're getting ready to hit the road for how ever long we could when my dog started sniffing my breath then laying his head on my chest, he wouldn't leave my side and he did this over and over. I had been really sick, I had somehow caught C-diff and felt pretty bad but was getting better. But afyer days of my dog acting this way I told my husband I'm going to see about my lungs before we take off. My doctor ordered me a CT scan to appease me and 2 hours after I had it they were on the phone saying I needed a PET scan immediately. So that's how my journey started, my dog saved my life. I never did have a cough, but did have pain in the spots where the cancer was found. I just racked it up to old age aches and pains..lol I can say my dog is pampered now more than most..lol
