Hello dj
Welcome to the site. Sounds like your husband is having very similar treatment to me. I am now 27 months out of treatment and looking and feeling well. Radiation seems to be a very high mountain on day 1, but push on and it will be worth it. For me, one day at a time was the way I handled it. Boy, did I count them off. I congratulated myself every day and found laughter wonderful although I sounded very peculiar I imagine. I tried to find something positive away from cancer every day.
People here have travelled your path and are here for you both, caregiver and patient.
Best wishes and love to you from Helen
