Information about cancer is available from the sources listed below. You may wish to check for additional information at your local library or bookstore and from support groups in your community.

National Cancer Institute (NCI) The National Cancer Institute is the principal federal agency working to prevent cancer and help patients live longer and healthier lives. Drawing on the knowledge and expertise of researchers at laboratories, cancer centers, and universities across the country, NCI strives to conduct and sponsor research and translate the results into information that will continue to benefit everyone.

Cancer Information Service (CIS) The Cancer Information Service, a national information and education network, is a free public service of NCI. The CIS meets the information needs of patients, the public, and health professionals. Specially trained staff provide the latest scientific information in understandable language, as well as a list of mammography facilities organized by state. CIS staff answers questions in English and Spanish and distributes NCI materials. The toll-free telephone number for the CIS is 1-800-4-CANCER (1-800-422-6237). People with TTY equipment may call 1-800-332-8615.

PDQ People who have cancer, their families, and doctors who care for cancer patients need timely and accurate information about cancer treatment. To meet these needs, NCI developed PDQ. This computer database gives both patients and doctors quick and easy access to the latest treatment information.

To use PDQ, doctors may use an office computer or the services of a medical library. By calling the CIS at 1-800-4-CANCER, doctors and patients can get PDQ information and learn how to use this system.

American Cancer Society (ACS) The American Cancer Society is a voluntary organization with local units all over the country. It supports research, conducts educational programs, and offers support groups and many other services to patients and their families. It also provides free booklets. To obtain
information about services and activities in local areas, call the ACS's toll-free number, 1-800-ACS-2345 (1-800-227-2345) or the number listed under American Cancer Society in the white pages of the telephone book.

National Women's Health Information Center (NWHIC) The National Women's Health Information Center, sponsored by the U.S. Public Health Service's Office on Women's Health and the Department of Defense, provides a centralized point of access to women's health information from the federal government and the private sector. To obtain information on breast cancer and other topics, call the NWHIC's toll-free number, 1-800-994-WOMAN.

Since the National Cancer Program began in 1971, persistent research efforts have led to significant progress in cancer detection, diagnosis, prevention, and treatment.

These efforts have resulted in an overall decrease in cancer death rates and in more effective treatments for patients.
