VOORHEES-- Crowds of well-wishers packed the Chick-Fil-A restaurant Tuesday to help a 12-year-old Voorhees Middle School student battling a rare form of cancer.

Brooke Mulford was diagnosed with neuroblastoma when she was 4 years old, according to the Voorhees Sun.

Brooke, a native of Salisbury, Md., now lives in Voorhees with her mother to be closer to the Children's Hospital of Philadelphia, where she is receiving treatment.

Reached Tuesday, a staffer at the restaurant said the crowds were "insane", as people lined up for a special promotion during which all proceeds were donated to Brooke's medical care. The promotion raised $17,500, the staffer said.

Brooke's family has also started a foundation benefitting research into pediatric cancer.
