Who We Are
The mission of the American Cancer Society is to improve the lives of people with cancer and their families through advocacy, research, and patient support, to ensure everyone has an opportunity to prevent, detect, treat, and survive cancer.
Cancer Information
At our National Cancer Information Center trained Cancer Information Specialists can answer questions 24 hours a day, every day of the year to empower you with accurate, up to date information to help you make educated health decisions. We connect patients, caregivers, and family members with valuable services and resources. Or ask us how you can get involved and support the fight against cancer.
In addition to the support we are providing to cancer patients who contact us via phone and chat, we’ll be helping offset feelings of isolation for families facing cancer and seeking information by offering video chat. Schedule a video chat today.
For medical questions, we encourage you to review our information with your doctor.
Online Resources
You'll find information on cancer prevention, reducing cancer risk, cancer types and treatment options, support programs and resources, and cancer research on cancer.org. We offer a personalized experience with interactive tools including online communities for patients, survivors, and caregivers.
Information is also available on volunteering, events, and donations.
