I have a painless bump on the right side of my lower lip. It grew in size over 4 weeks from the size of a pea to twice the size. It is the colour of my lip. There is an ulcer right next to the growth. And I have accidentally bitten down on it 2-3 times.
I saw the dentist and she drained it. It contained clear pus and she assured me it is not cancerous. She prescribed a course of antibiotics (also I have slightly elevated lymphocytes) and suspects an infection.
While it has been decreasing in size the pus continues to come back and she has had to drain it 2 times so far.
Should I be worried about oral cancer?
