There are tumors, and then there are tumors. The particular type of cells determines the treatment.
For instance, the parietal area of the brain, where Kennedy's tumor is situated, governs the ability to speak and understand, movement on the right side of the body. One doctor describes it as high-risk real estate.
Surgery in this area can be tricky. A doctor on CNN just a bit ago said this -My father died of a malignant brain tumor, back in 1945. He had 3 craniotomies over a period of 18 months. Each time the tumor grew back, because they were unable to get out all the tumor cells."The problem with glioma is, when surgeons go in and try to work on this, it's nearly impossible to tell what is tumor and what is brain cells, because this is a tumor of the brain cells," she said. The result, sometimes, is that the surgery causes brain damage, Wright said.
