The American Cancer Society (ACS)

The American Cancer Society published the Manual Of Tumor Nomenclature and Coding (MONTAC) in 1951. That early document served as the basis for a series of refinements in cancer morphology codes, including the Systematized Nomenclature Of Pathology (SNOP) and later the Systematized Nomenclature Of Medicine (SNOMED), published by the College of American Pathologists, and the International Classification of Disease for Oncology, (ICD-0-3), published by the World Health Organization.
