Table of Neoplasms — B
Find the anatomical site, then read across to the column matching the behaviour the pathology report describes. One site yields six different codes depending on whether the neoplasm is malignant, in situ, benign, or of uncertain behaviour. 117 sites beginning with B.
A blank cell means the column does not apply to that site — not that the code is missing.
