Glad you are doing so well after your treatment. I have found this whole site to be full of information for all stages of treatment. People here are so supportive and offer advice with grace, understanding and humour.
I am very impressed that you can walk a mile. I certainly couldn't have done that for a long time out of treatment. Listen to your body if you become overtired. Radiation affects our bone marrow and therefore our blood.
You are doing so well, please update us as you improve.
Love and light from Helen
