The American Cancer Society (ACS) seeks to end cancer suffering. The not-for-profit organization is staffed by professionals and millions of volunteers at more than 900 local offices nationwide. ACS is the largest source of private cancer-research funds in the US. Some recipients of the society's total $4 billion in funding include 47 Nobel Prize laureates. In addition to research, the ACS supports detection, treatment, and education programs. The organization encourages prevention efforts through its Quit for Life antismoking campaign and the International Relay For Life. Patient services include moral support, transportation to and from treatment, and camps for children who have cancer.
