I understand your reaction but, please remember that neither Mayo nor any other physicians are responsible for decisions on your healthcare; you are. That is why they always explain the situation to you and then they wait for your decision on the options. This means that, in addition to Q&A with your physician, you need to analyze all other sources of information such as second opinions, your own research (there is an incredible amount of information available), experience of others, etc. etc. It is painstaking work and takes time but you need to do it and then you will be in a position to make the most informed decision based on your situation. Medicine is not a precise science since it deals with variable things: humans. Biology is not as precise as physics (except at the quantum level) and deals with statistics and probability! Everything in medicine has a risk/reward aspect to the decision. I wish there were an easier way to make these decisions.
