i think .. and im pretty suure , that i have oral cancer. last week i went for an xray due to chest pains. and the doctor also looked at the back of my throat. turns out i had a sinus infection. if i did have oral cancer somewhere in my mouth , would the doctor be able to tell when he looked at the back of my throat. and would something have showed up in the xrays? pleasee help . and no my doctor didnt tell me that i had oral cancer. im just assuming i do because of the symptoms i have. i have lumps on the back of my tongue that i never noticed before, and it seems like im getting things that feel like canker sores all over my mouth. plus i have this hard thing on the bottom of my mouth .its on the jaw , towards the front of my mouth. a lot of people are telling me that its probably a torus , but i worry a lot and my luck its probably
