The International Classification of Diseases for Oncology (ICD-O) is a domain specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. The International Statistical Classification of Diseases and Related Health Problems (commonly known by the abbreviation ICD) is a detailed description of known diseases and injuries. ... Tumor (American English) or tumour (British English) originally means swelling, and is sometimes still used with that meaning. ... A cancer registry is a systematic collection of data about cancer and tumor diseases. ...

It is currently in its third revision.

Axes

The classification has two axes:

Morphology

The morphology axis is for the morphology of the tumor. Comparative anatomy is the study of similarities and differences in organisms. ...

This axis has additional importance, because the Systematized Nomenclature of Medicine has adopted ICD-O's classification of morphology. The Systematized Nomenclature of Medicine (SNOMED) is a multiaxial, hierarchical classification system. ...
