 But day one is just one day. At the Leukemia and Lymphoma Society, we are here to help you move past day one. On day 45, I discovered an online community who shared great tips for in-treatment care. I missed a lot of school during treatment, and LLS helped me keep up. To learn more and get help on day two, day 28, or any day, please visit LLS.org or call 1-800-955-4572.
