I think that you get one chance to decide something in your journey, and that is to pick the best cancer institution and team that you can find, afford, or that your insurance will pay for. After that we have to put ourselves in their hands.
For me, even with a strong science background, I went with opinions of others who were experts in the field, to find the right hospital. I don't think that I was capable of asking the right questions, nor was I capable of understanding the answers.
Respectfully, 99.9% of us are not physicists - anyone that is, is going to have to dumb down the answers for us to get us the basic understanding of things, and then, your case is really unique and cannot be compared side by side with any other case that is exactly the same. I get more than most, the desire to understand all this, and I question everything. But at some point you have to say these are smart, current people in knowledge, with the latest technologies at their disposal, and they and the institution have stellar ratings when looked at by other critical sources. I think anyone who believes that they can get up to speed on radiation technologies enough to have an intelligent conversation with the planning physicist, in which they could actually be a productive part of it all, and afterwards make a decision to do A or B is kidding themselves.
We have lost a couple people here that got caught up in multiple opinions and wasted lots of time traveling from place to place. Not suggesting that you are one of those people. But at some point in time, cancer treatment becomes less something that we can actually contribute to, and more a leap of faith with people that we put our trust in after evaluating not what they are going to do, but the doctors themselves. I think at at top rated cancer center, like an NCI designated CCC teaching institution, which has multiple teams of doctors, and very strict protocols and oversight, it would be hard not to get the best plan and treatments.
Picking the institution and team is the one thing you have a choice in. We are not going to tell doctors how to treat us for the most part. Our desire for control anything in this situation in particular is a castle built on sand.
