Guide for use:Help on this term

ICD-O morphology describes histology and behaviour as separate variables, recognising that there are a large number of possible combinations.

In ICD-O, morphology is a 4-digit number ranging from 8000 to 9989, and behaviour is a single digit which can be 0, 1, 2, 3, 6 or 9. 

When the morphology is unknown, record 8000 and the appropriate behaviour code. For example, a tumour of unknown morphology with a behaviour code of "3" for a malignant primary site tumour would be recorded as 8000/3.
