I've asked doctors in person at hospitals this question: why has there been no cure found for cancer? All they have ever given me is a list of symptoms and how to treat them. "Well this causes that type of symptom and if we don't conquer that trial then this symptom will pop up...blahdy blahdy blah!" I was thinking, "what in the hell are you talking about?" I was clearly asking something specific, but they could not answer it with a straight answer.
