i lost my dad to cancer a few months back, i had a small ulcer appear 4 days ago on the left side of my tongue. this is now a white patch which is very tender. i have also found 2 small lumps under my left arm (these may not be connected). iam terrified to go to the doctors, my wife made me an appointment but i cancelled it, does this sound like tongue or mouth cancer? iam 36 with a 6yo girl x
