JoYo -

I think if you ask fifty people diagnosed with the same or similar SCC of the tongue, you would probably get 30 different responses.....

Here's mine,

Prior to both resections my tongue felt thick and did not respond well to movement. In both cases there was a lump present.

You should not wait. have the lump checked out. Perhaps request a needle biopsy, if possible.

The numbness could be related to the lump OR just nerve re-generation

Either way, get yourself in front of an ENT. Preferably the one that knows your history and is competent in treating oral cancers.

Good Luck
