About this Website
This is the central website for the National Cancer Institute (NCI), the U.S. government’s principal agency for cancer research. NCI is mandated by U.S. law to disseminate information about cancer and cancer research. This website serves as an important means to achieving that mission.
Information about Cancer
This website offers free, credible, current, comprehensive information about cancer prevention and screening, diagnosis and treatment, research across the cancer spectrum, clinical trials, and news and links to other NCI websites.
The information on this site is science-based, authoritative, and up-to-date. Medical experts, cancer researchers, and editors review the content before it is published to the website.
The Physician Data Query (PDQ®), NCI’s comprehensive cancer information database, forms the core of the information for patients and health professionals. It is regularly updated with the latest evidence-based information. The PDQ cancer information summaries are developed and maintained by the PDQ Editorial Boards.
NCI also provides cancer information in Spanish.
Information about NCI-Supported Research
This website also provides information about NCI-supported research and NCI’s grants and training programs. We report on ongoing progress in cancer research through news releases, research articles, and NCI’s Cancer Currents blog.
This information is reviewed by subject matter experts and updated regularly.
