The trouble is there are so many variables. But talking with oncologist can help considerably. You might notice the doctor leaning toward one treatment, but will also tell you other options. If he's a good doctor that is; and you have to decide that by observing and listening. We're all different, but I've not heard of many (Any?) doctors who do not always say radiation is next and just assume you will go along with it. Double negative there. Sorry. I just think doctors try to cover themselves. All of them.
