hello,
a canker sore is what led me to my dentist..it was so painful and it wouldnt go away. that same day i was at the perodontist he did a uv test and set up for a biopsy last thursday. I am waiting for the results. i dont know what to think. i smoked for 29 years and last year i quit smoking as a rememberance to my mother whom i lost in 2006(colon cancer). now look at me possibly facing oral cancer..what else could the spot be that my dentist saw ???
