Extreme Makeover: Home Edition S07E13 - Cowan Family

At the age of five, Kori Cowan was diagnosed with a congenital blood disease affecting her immune system. Since then, her parents have made multiple trips every month to Riley Hospital in Indianapolis, where Kori meets with her doctors and receives intravenous blood infusions. Recently Kori started developing polyps in her nasal cavity and behind her eyes. She has already endured 17 operations as a result of these painful growths that have to be surgically removed. Doctors believe the polyps may be the result of environmental issues in the family's home, including an extreme mold infestation. Ryan, the oldest boy, has also fallen ill and gone to live with his biological father - tearing this close-knit family apart.
