Marcy Scott, the promotion and marketing director at Atlanta Motor Speedway who also worked with several drivers during a long career in NASCAR, died Friday after battling breast cancer. She was 42.

AMS president Ed Clark said Scott died at her parents' home in the Atlanta suburb of Lilburn.

Scott joined the speedway in 2005 after working for several teams and sponsors, her list of drivers including Matt Kenseth, Ricky Craven and Jeff Green. Clark praised her contributions to the sport and said everyone will miss "her way of making any task fun and enjoyable."

Scott was initially diagnosed in 2009 and underwent extensive treatment, including a dozen surgeries. She revealed on her blog that the disease had returned in her brain after she fell ill in late May.
