Tifani Hodges is a grateful mother. When her son, Tristin Ross, was three years old, he was diagnosed with stage IV neuroblastoma. His treatment included a bone marrow transplant. Then, at the age of five, Tristin developed acute myelogenous leukemia (AML) - a fast-growing cancer of the blood and bone marrow. In the past five years, he has received two cord blood transplants at Children's Hospital of Pittsburgh of UPMC. Today, Tristin is a healthy, active 10-year-old, with no restrictions, who likes to ride his bike and play outside from dawn to dusk. Tristin's family will forever be thankful to the generous mothers who chose to donate their babies' cord blood to potentially give someone - in this case, Tristin - a second chance at life.
