I had a spot on the right lateral side of my tongue. all my doctors and dentist kept insisting i was either chewing on my tongue at night when i slept, or it was lichenplanus. But they referred me to a oral surgeon and he tried some things and they didn't work. So then he took a biopsy, 2 pieces. And that was charged to my medical insurance. And it turned out to be stage 3 SCC. So if the ENT doesn't know, check with a oral surgeon. Hopefully it's a fungus, irritation or anything but cancer, but if it's cancer, this is the right place!
