My father, had of bitten his cheeks while asleep many time, few weeks ago he had slight growth (not tumor sort of) on his cheeks with an Angular cut till his lower lip with white patches on top. He was given medicines and some mouthwash after that there is definitely some improvement but slow and white patches are almost gone. We have sent it for biopsy as well, will get report within 10 days. It's painless and doesn't bless. No pain in neck or ears, no hoarseness and does not bleed.
