The National Association for Proton Therapy (NAPT) is an independent non-profit organization founded in 1990 to educate and raise public awareness about the clinical benefits of proton therapy. It serves as a resource center for patients, physicians, health care providers, insurers, academic medical centers, hospitals, cancer centers, Medicare, the U.S. Congress, health care agencies, and the news media. The NAPT’s supporting members include 40 of the nation’s leading cancer centers, a number of whom are National Cancer Institute-designated comprehensive cancer centers and National Comprehensive Care Network (NCCN) members.
