@colleenyoung Radiologist oncologist agreed to a 5-day radiation course stretched over two weeks time to help manage the fatigue. It is actually "Photon" radiation (I didn't realize this until after I had made the initial post). Not sure if I can change the wording in my original question or not. I had my fifth and final dose yesterday, 7/31 and am quite fatigued. Rest helps, but still no endurance to do much.
