I have a couple of tumors none of them really effect me, except 1. i have a giant cafe au lait spot that runs from my mid calf of my right leg up to like mid thigh and it wraps around my leg. About 3 inches under my knee there is a slightly big its not huge tumor and about 3 inches arund the tumor is all numb... But the tumor itself is sensitive it hurts if its bumped. Does any1 else have any numbness around there tumors? What does this mean?
