An ulcer in a tumor happens when the tumor grows so aggressively , that it is taking away space from itself to grow and then the cells squish each other to death and an ulcer occurs. This is also the reason why this will not heal by itself. Only debulking (taking as much of the tumor away surgically) or taking the whole tumor would help here. The antibiotics are given to prevent infection or fight infection of the ulcer. tumor ulcers usually are not very painful, if painful at all.
