Lexi Derringer is only 3 years old, but she is one tough cookie.
From the day she was born prematurely at 29 weeks, she has been fighting to live. She spent the first two months of her life at Kosair Hospital, and she's there again. Only this time, she has cancer.
She was diagnosed with acute lymphocytic leukemia, known as ALL, on Friday, Nov. 13. Friday the 13th is widely known as an unlucky day, but for Lexi's parents, Kevin and Christy Derringer of Campbellsville, that day was a nightmare.
