Our Global Vision As a leader in cancer control since 1913, the American Cancer Society is committed to saving lives from cancer and reducing the global threat of the disease. We combine our relentless passion with the wisdom of experience to make this vision a reality by focusing on countries with the most need and where measurable results can be achieved. We know that cancer is one of the most preventable — and the most curable — of major chronic, life-threatening diseases. We recognize tobacco as the single most preventable cause of death. We’re working to reduce the incidence of tobacco-related cancers in low- and middle-income countries with a special emphasis on sub-Saharan Africa. In collaboration with a worldwide network of partnerships, we are urging governments and international organizations to recognize that cancer is a global priority requiring an urgent response.
