The American Cancer Society is a leading cancer-fighting organization dedicated to ending cancer for everyone. It improves the lives of people with cancer and their families by combating cancer through advocacy, research, and patient support, ensuring that everyone has an opportunity to prevent, detect, treat, and survive cancer. Key initiatives include providing free lodging at Hope Lodge facilities and lodging grants, offering transportation to treatment through the Road to Recovery program and transportation grants, and developing resources like the ACS CARES™ mobile app.

They also focus on risk reduction through healthy lifestyle promotion, tobacco cessation, HPV prevention, and recommended cancer screenings. Support extends to families and caregivers, and the organization engages volunteers and fundraisers through events like Relay For Life and Making Strides Against Breast Cancer. Furthermore, the American Cancer Society conducts and funds high-impact research across various scientific disciplines to find better treatments, uncover causes, and improve patients' quality of life.
