The national nonprofit CancerCare offers counseling, education, and practical advice to people affected by cancer. Thursday night at the Hilton New York, the organization honored three of the organization’s supporters at its 22nd annual Human Services Dinner. The event, which had as its chairman top executives from AstraZeneca, Bristol-Myers Squibb, Bloomingdale’s, and Polo Ralph Lauren, paid tribute to David Chapman, who heads the advertising agency Thomas Ferguson Associates, which manages CancerCare’s advertising on a pro-bono basis; the president of Pfizer Global Pharmaceuticals, Karen Katen, and the president of the glittering handbag empire Judith Leiber, Margaret Siegel, who is a vice president of CancerCare’s board. Last spring, Ms. Siegel introduced the Judith Leiber Children’s Art Bag, featuring children’s artwork, with proceeds benefiting the CancerCare for Kids program, which helps parents and children cope with the disease.

With an annual budget of $15 million, CancerCare serves cancer patients and survivors, caregivers, and family members. The organization employs more than 40 oncology social workers and provides continuing education to many more. “We focus on the emotional, social, and financial burdens of cancer,” the executive director of CancerCare, Diane Blum, said.

The organization has thrived under her and her colleague’s long-term leadership. Ms. Blum joined the 61-year-old organization in 1984 as director of social service, after working as a social-work supervisor at Memorial Sloan-Kettering Cancer Center and the Dana Farber Cancer Institute. The organization’s president, Paul Friedman, a senior managing director at Bear Stearns, became involved with CancerCare more than 15 years ago as a member of the junior committee.
