Photos: Lizzie Bell's burden

Lizzie Bell, a recent Salpointe Catholic High School graduate and aspiring photographer, has been in and out of hospitals since she was a baby fighting a rare disease that requires blood transfusions every two weeks.

Lizzie says she does not not want to think about leaving Tucson on June 30 and what she faces at the University of Minnesota Medical Center in Minneapolis.

It is there on July 25 that Lizzie is set to receive a potentially life-saving bone marrow transplant from an anonymous donor who perfectly matches her.
