Supermodel raises awareness for pediatric cancer

Crawford's younger brother, Jeff, was a patient at University of Wisconsin Children's Hospital. The boy died of leukemia in 1975 just before his fourth birthday.

Crawford is the honorary chair of Kids with Courage, which had its fourth reunion of childhood cancer survivors Saturday in Madison.

She was also part of the three previous reunions in 1993, 1998 and 2003.

The University of Wisconsin says Crawford has been contributing time and money to the UW Pediatric Oncology program for nearly 20 years.
