The American Cancer Society is the nationwide, community-based, voluntary health organization dedicated to eliminating cancer as a major health problem by preventing cancer, saving lives from cancer, and diminishing suffering from cancer through research, education, advocacy, and service.
At the American Cancer Society, we're on a mission to save lives.
The American Cancer Society was founded in 1913 as the American Society for the Control of Cancer. It was organized as the American Cancer Society in 1945 and has been present in Colorado since 1946. To this end the American Cancer Society is the largest source of private, nonprofit cancer research funds in the United States, offers programs and information on cancer prevention, detection, and treatment, educates policy makers on local, state, and national levels, and provides a variety of programs and services.
