I am so sorry you are having such a hard time. Does your area have a state medical board where you can find information about oncologists in your area? Does your insurance carrier have a list of participating oncologists? I wonder if the websites of the local hospitals has a physician list according to medical specialty? There are a couple websites where you can find basic information about oncologists in your area. One is drscore.com. Can one of your other physicians suggest a new oncologist? In the meantime I would keep asking the radiologist questions and keep reporting your symptoms. He or she might have suggestions about how to cope with them. Keep showing up at the ER until someone helps you or refers you to a doctor who can help you.
Good luck. I have my fingers crossed for you, so don't give up.
