Doctors want their patients to heal. I don't doubt that. However, they treat many, and we are one. They get distracted, they get busy, they make generalizations, they make mistakes. We don't know much, but as you say, we can read and we can question. We have to.
He needed the surgery because there was a very large tumor growing on his tibia. It was his second operation to address this issue. Previously, it seemed the tumor had been removed, from a different area, but it grew back even larger. The decision was that the whole section of the tibia had to come out. As the doctor said, "That tumor is gone".
Good riddance :))
