Eight-year-old Andy Dunn of McMinnville is feeling as tall as his big brother, Ray, an MTSU freshman, right now.The youngest Dunn, a cancer survivor thanks in part to donated blood products, will be the official kickoff kid at the MTSU-Western Kentucky football game at Floyd Stadium Oct. 6, when the American Red Cross announces the winner of this week’s Oct. 3-5 campus blood drives.“Andy is 8 years old now and had his three-year transplant birthday in June,” explains mom Dot Dunn. “All of his tests have come back with no evidence of disease. God has been very good to us.”The youngest Dunn was diagnosed with stage IV neuroblastoma in 2008 and underwent an excruciating series of tests, treatments (including a stem-cell transplant and a unique drug study) and follow-up care at Vanderbilt Children’s Hospital to help him beat the disease.
