Marcia Wallace of Bob Newhart Show fame was honored by the Roswell Park Cancer Institute Saturday in Buffalo, N.Y., for helping educate Americans about the importance of early cancer detection and inspiring others through her 20 years as a breast cancer survivor.

Wallace, who voices schoolteacher Edna Krabappel on The Simpsons, said she keeps up a steady pace of speaking engagements to promote vigilance even in an age of improved cancer testing and treatment.

In accepting the Gilda Radner Courage Award, she said she was fortunate to catch her cancer at an early stage and encourages people to "use all the tools" to give themselves the same advantage.
