research

In the case of Marie's tumors, it started as one tumor and recurred. Then it began to come back in as multiple tumors. And not it has seeded with many tumors growing. Why the progression from bad to worse? Is it a disease that runs a course? Is it a case of not finding the correct treatment? What information is being gained to help a future victim? I don't believe that information on benign brain tumors is being kept. I'm doubting that not much, if any, research is being done.
