DITTO to everything Tina said. I was mis-diagnosed for 3 months by 2 different GPs, during which time my tongue tumor grew to the point where I lost 75% of it.

Go to see a good dentist and/or an ENT familiar with oral cancer.

And throw the cigs out...NOW, you can do it. I smoked for 40 year and if I can quit, so can you. Stopping now may keep you away from this forum forever more.

DX 12/6/10 of T3 SCC Tongue.
Surgery 1/3/11 was hemigloss & forearm free flap, midline mandibulectomy, Neck Disection-All nodes clear.
Ended rads 5/11/11. Taste buds back to about 80%. PEG removed 4/5/12, experimenting eating real food again. If I can do this, so can you !! Stay Strong.
