The Office of Cancer Complementary and Alternative Medicine (OCCAM) is an office of the National Cancer Institute (NCI) in the Division of Cancer Treatment and Diagnosis. OCCAM was founded in 1998 and is responsible for NCI’s research agenda in complementary and alternative medicine (CAM), as it relates to cancer prevention, diagnosis, treatment, and symptom management. The OCCAM differs from the National Center for Complementary and Alternative Medicine (NCCAM) in that it is exclusively focused on cancer, while the NCCAM funds a much broader program of NIH research into CAM treatments for all diseases and disorders.
