I have one single red spot circular in look, not hard, size of a eraser, on soft palate in center of roof of mouth, no pain, only slight itch I noticed a few weeks ago..... Normally wouldn t be worried but this little spot was there in march and was smaller, it DID go away but now it s back. I am 31 years old, former pack a day smoker, quit smoking 5 months ago cold turkey, been worried. Could this be oral cancer? I took a picture but cant send on here....
