I have a white spot on the right side, top, back of my tongue.  It is circular with a hole in the middle.  it doesnt really hurt.  My mother had oral cancer so I am concerned.  She drank and smoked which I dont.
Hi, Thanks for writing in. The symptoms of an oral cancer includes one or more of the following sore that doesn't heal. A lump or thickening of the skin or lining of your mouth. A white or reddish patch on the inside of your mouth. Loose teeth. Poorly fitting dentures. Tongue pain. Jaw pain or stiffness. Difficult or painful chewing. A white area in the mouth is to be evaluated clinically for any progression in the size and appearance. Please have it examined by an ENT specialist and do not worry about cancer even if your mother had it.
