Hi, everyone! This is my first post here.

I'm Mickey, 27 years old. About three weeks ago, I got this ulcer in my mouth. Since I've always had ulcers, I didn't pay much attention to this. However, unlike the previous ones, this one doesn't hurt, and about 4days ago, it started to grow, and still doesn't hurt now. I felt it with my fingers and could feel some hard particles underneath its edge. It's now about 0.4 by 0.23 inches in an irregular shape. I have already scheduled with an oral surgeon, but it would be two weeks later! I'm now worried sick that it might be oral cancer and can't do anything right, been distracted all day long thinking about it. According to my symptoms, are there any other explanations than cancer that it might be?
