About NAPT: The Voice of the Proton Community

The National Association for Proton Therapy (NAPT) is an independent nonprofit organization founded in 1990 to educate and increase awareness about the clinical benefits of proton therapy. Proton therapy is one of the most advanced methods of radiation treatment available today due to its unique ability to allow radiation treatment doses to be delivered to cancerous tumors while minimizing radiation exposure to healthy tissues and organs. Reducing unnecessary radiation for cancer patients results in the potential for fewer short and long term side effects.

The NAPT’s mission is to work collaboratively to;

  • educate and raise awareness of the clinical benefits of proton therapy among patients, providers, clinicians, payers, policymakers, and other stakeholders,
  • ensure patient choice and access to affordable proton therapy, and
  • encourage cooperative research and innovation to advance the appropriate and cost-effective utilization of proton therapy.

The NAPT’s supporting members include 42 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.
