Dear Friend Carole... I know my neighbor, who's also a nurse, had a lumpectomy, lymph nodes removed to be safe, chemo and opted for radiation also to be safe. I don't recall how many radiation treatments she had but the whole process exhausted her, but her reactions weren't too bad. I can ask her if you want me to. She's a strong advocate for B.C. research and activities and I know would be more than happy to help you...Email me if you want....Love, Karen ...Many heartfelt prayers to your mom.
