The American Cancer Society offers programs and services to help you during and after cancer treatment. Below are some of the resources we provide. We can also help you find other free or low-cost resources available.
What does it take to outsmart cancer? Research. We’ve invested more than $5 billion in cancer research since 1946, all to find more – and better – treatments, uncover factors that may cause cancer, and improve cancer patients’ quality of life.
We couldn’t do what we do without our volunteers and donors. Together, we’re making a difference – and you can, too. Become a volunteer, make a tax-deductible donation, or participate in a fundraising event to help us save lives.
At the American Cancer Society, we’re on a mission to free the world from cancer. Until we do, we’ll be funding and conducting research, sharing expert information, supporting patients, and spreading the word about prevention. All so you can live longer — and better.
