Hi there. So I'm concerned if I have oral cancer :(. I have had a sore bruised up gum for 4 days now, my neck hurts, my tongue is a little numb from the side my gum is bruised, my head hurts, it hurts when i swallow, and my ear hurts. I looked up these symptoms and they seem to match oral cancer. Not to mention I've had an ulcar on my lip which I've had for 2 weeks now. It doesn't run in my family, but I'm seeing the dentist tomorrow. Do you reckon it could be oral cancer? It's mainly my right side which is hurting, where the gum is. Also I'm aged 16. And the top of my mouth inside, the oral soft tissue is looking abit yellow. I'm just concerned.
