WAUKESHA, Wis. – Lori Williams knows a thing or two about childhood cancer. Her son Thomas is a cancer survivor and was diagnosed with leukemia when he was only 2 years old. Williams said since his diagnosis, she’s been on a mission to raise awareness about childhood cancer research. That’s why she hosted a fundraiser at Liberty Dance Center in Waukesha in partnership with the St. Baldrick’s Foundation, a charity for childhood cancer research.
