Hi, I'm new to the board. It's really great that this is around to help people.

Ok, I am very worried here. I am 20 years old and had dipped for 2-3 years on and off after highschool. I recently quit when i found a small lump about the size of a pea on my lower inside gum just about where the gums reach the floor of the mouth. The lump is not visible but can be detected through touch. It is hard but moveable in all directions as if it is attached to the gum elastically. There is no serious pain, only a feeling of slight irritation. I am very worried. I know no one here could possibly make a diagnosis but does this sound like a mouth cancer to you? And what are the chances it is malignant vs something benign?
