hm. that's interesting. it's not uncommon to develop numbness at the surgical site of any surgery. sometimes this is temporary and sometimes it's permanent. my question would be how extensive your skin cancer surgery was. for example was it a small cancer the size of a pencil eraser perhaps and the surgeon just numbed it up took it off and closed up the incision with a couple of sutures? or was it a more extensive surgery possibly with general anesthesia and the doctor used a "skin flap" to close the wound? (a skin flap usually leaves a scar that has 3 or 4 lines or arms to it rather than just the single straight line of a single incision. ) if your surgery was fairly extensive you might want to follow up on that tongue numbness. it's not uncommon for a nerve to become irritated from extensive (deep) facial surgery but it would be pretty odd for this tongue numbness to be related to the surgery since it's occurring so long after the fact. still it never hurts to check it out. hope this helps!
i had a skin cancer removed from my left jaw/cheek in march. i developed a numbness in that area. . i now have the same type numbness on the left side of my tongue. should i be concerned?
