NCCN History

On January 31, 1995, a press conference was held to announce the creation of a national alliance to develop and institute standards of care for the treatment of cancer and perform outcomes research – and so the NCCN was born. With 13 original NCCN Member Institutions, the goal was to ensure delivery of high-quality, cost-effective services to people with cancer across the country. NCCN became a developer and promoter of national programs to facilitate the fulfillment of NCCN Member Institution missions in education, research, and patient care. Now an alliance of 33 of the leading cancer centers, NCCN develops and communicates scientific, evaluative information to better inform the decision-making process between patients and physicians, ultimately improving patient outcomes.
