Hi, I'm a junior in high school and I recently noticed a lump in my mouth and it hurts a bit. I've been smoking ciggarettes for about a year and a half. I also smoked marijuana frequently and drank alcohol a couple of times. I looked up the symptoms of oral cancer and it sounded like I had a couple of them. A sore in my mouth, a whitish patch, and also my two top front teeth are making a small gap between them. I took off my braces about a year ago. Can anyone tell me if its possible that I have oral cancer at 16? Thanks in advance
