Three highly qualified experts in the same specialty may highlight different nuances of your situaiton and weigh available treatment options differently. Sometimes, one of the experts may have a dissenting view. We call it "minority report", as in a movie "Minority Report" with Tom Cruise. A dissenting view, when it exists, matters greatly for you, because it may lead to additional steps to clarify a diagnosis at a deeper level. It may challenge the default assumptions for diagnosis and treatment. You always want to hear a minority report, just like Tom Cruise did in that movie. On the other hand, all three perfect experts may render similar opinions on the diagnosis and preferred treatment options for you. Then it gives you an extra degree of confidence in a planned treatment. That is a lot of value too.
