@marannolson, I'm sorry you weren't able to do it! It was a wonderful experience. The healing process is a bit longer. I was nervous about the side effects of the normal Radiation therapy. I'm Asthmatic and Diabetic. When this came to my attention, I was quite relieved. The only discomfort was when the tube was switched for Radiation treatment and when it was removed. Changing the dressing was a bit uncomfortable, also! My Medical Team is AWESOME! They prepared me completely. The compassion and care has been excellent! I Love Mayo Clinic!
