What is the cost of brain surgery?

Brain surgery is expensive but it depends on a lot of factors such as complications after surgery and how long your hospital stay is. I had brain surgery in November of 2006 but I had complications that left my left side weaker than my right and was required to have extensive therapy and over a month and half hospital stay. Over all, my bills have reached close to $750,000 or more. That is not including prescription costs since my surgery.
