What We Do

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.

Encouraging Prevention

We help you take steps to prevent cancer or find it at its earliest, most treatable stage.

Providing Support

We’re here for you every second of every day, to help you through every step of your cancer experience.

Making a Difference

Today, almost 1,700 people in the US will die of cancer. That adds up to more than 600,000 Americans dying of cancer this year alone. That’s why, with our 1.5 million volunteers, we are taking action.

Fighting for What’s Right

We work with lawmakers to pass laws to defeat cancer and rally communities worldwide to join our mission.

Access to Care

We're working every day to free the world from the pain and suffering from cancer, but we can't continue our progress while millions of underinsured and uninsured Americans don't have access to lifesaving cancer care.

Fostering Innovation

We fund and conduct lifesaving research that helps us better understand, prevent, and find cures for cancer.

Supporting Multicultural Communities

The American Cancer Society supports multicultural communities in a variety of ways to help reduce the risk of cancer.

Cancer Stories

Read stories of real people who have survived cancer and the positive impact the American Cancer Society had on their cancer journey.

Advancing Health Equity – Addressing Cancer Disparities

No one should be disadvantaged in their fight against cancer because of how much money they make, the color of their skin, their sexual orientation, their gender identity, their disability status, or where they live.

Contact Us

We are available 24 hours day, 7 days a week, at 1-800-227-2345 and through this website.
