I never understood the concept of how an insurance company could tell a patient "you can not use the treatment your doctor prescribed which will give you the best chance of beating your cancer - but instead you have to try a cheaper drug first and fail on it - then you can try the one that might help". What they do not understand is that the first try is your best try. When you have a recurrence, the tumor is usually worse - you may be left with permanent neurological problems and even if cured at that point, your lifelong medical costs are going to be higher.
This is great news for Pennsylvania patients. We need this country wide!
