The American Cancer Society is a nationwide, community-based voluntary health organization dedicated to eliminating cancer as a major health problem. While most people know us for our research, we do so much more. We attack cancer from every angle. We promote healthy lifestyles to help you prevent cancer. We research cancer and its causes to find more answers and better treatments. We fight for lifesaving policy changes. We provide everything from emotional support to the latest cancer information for those who have been touched by cancer. And we do it all 24 hours a day, 7 days a week.
