My brother had an astrocytomas glioma removed from his right side of his brain. The doctors are suggesting radiation. The operation left him with no feeling in left arm and leg, also vision problems. The tumor was both matter and fluid and had many vessels attached to it. The doctor says some was stage 2 and some was stage 4. It was sent to two different places and took 3 weeks to get results. Will this return and what all can be done to cure this brain tumor? The doctor said the mass was about 2 inches big and had been there for many years. We are concerned that he will not regain use of his arm, leg and vision. How long can that take to return?
