So I went to the dentist on Friday who noticed a skin tag type flap of skin on my inside of my left cheek at the top. He asked if I hurt it and I said not that I know of. He told me to come back in 2 weeks to see if it's healed if not I have to go for tests. He said it was unlikely to be sinister but obviously I can't help but worry now and these 2 weeks are scary. Is there another possible cause other than mouth cancer and are there any ways to try and heal it before my appointment.

I'm female 30.
