Dear Friends of The Cancer League,

Nearly 2 million Americans will be diagnosed with cancer in 2025 alone. Despite these staggering numbers and while research has led to groundbreaking treatments and lifesaving advances, progress is now at risk. Critical funding for cancer research has faced significant cuts, leaving scientists without the resources they need to continue promising studies.The fight against cancer is far from over, and without urgent action, we risk losing momentum at the very moment when hope has never been closer.

Please consider supporting our annual Holly Ball black tie gala, an evening dedicated to raising funds to support groundbreaking research in cancer treatment, on Friday, December 5, 2025, at the Claremont Country Club. Your support in underwriting the Holly Ball enables us to give 100% of the event’s net proceeds directly to vital cancer research projects andorganizations that help those affected by cancer. Please find information about sponsorship opportunities below.

Thank you for considering this opportunity to support us in the fight against cancer. Your support is not just a donation; it’s a way to make a real impact and bring us closer to a cure. Together, we can plant the seeds for a brighter future!

With gratitude,

LISA SAUER Chair, Holly Ball 2025
