I assume the fatigue is dose and length of treatment related. Last year I had radiation for stage 1 lung cancer. 3 treatments over a week. I thought I would escape the fatigue, but no it really hits you over the head- it got better over a few months.
Another peculiar thing happened- rib fractures. After 3 months I broke ribs on right side after an indoor fall- nothing serious I thought. Another 3 months later I fractured ribs on left side- by lifting something heavy. I was later told that radiation could make the ribs more susceptible to injury.
