Recently, I noticed a small (~.5" dia) lump in the floor of my
mouth. It is not visible from above, or below, but I can feel it. It all came in a day, I did not notice it when shaving a couple of days ago, but Friday night my jaw
was somewhat sore like I had a cramped jaw
muscle (which I get sometimes when yawning), and I felt and noticed the small lump.
Should I be concerned that this is cancerous?
