Why are we doing this? In 2004, my brother Dennis – at the young age of six – was diagnosed with acute myeloid leukemia (AML). Though chemotherapy forced the cancer into remission, it soon returned and he was in a battle for his life. After months of waiting and with only a one in 40,000 chance of finding a stem cell donor match, we learned of an adult match that would save my brother’s life. Dennis has been in remission for nearly ten years; in fact after five years in remission, he's now considered to be cured.
