I've had this pink inner cheek lump for over a year, and my last dentist did not seem at all concerned about it. However, I went for a check-up today and another dentist said that while she was not concerned, she wants to send me to a dental hospital for another look and possibly biopsy. She says it appears harmless but it needs checking because I've had it for over a year. Of course, I'm now worried it's oral cancer or cancer that's spread from somewhere else. I'm 26, don't smoke, drink lightly and don't have HPV, but I'm still very stressed out. I do have terrible health anxiety (to the point where it's made me agoraphobic.) Can anyone give me an indication of what they think the lump is?
