Susan Butcher, a 4-time winner of the Iditarod, was diagnosed with leukemia last year. She underwent a bone marrow transplant last month in Seattle, and is currently in the early stages of recovery from that procedure. Her long-term plan is to join another 50-plus cancer survivor, Dee Dee Jonrowe, and compete in the Iditarod again.
You can follow her progress in her fight against leukemia via her web site.
