ICD-O-3 Errata and Clarifications

It is very important to examine the errata pages and update printed copies of the International Classification of Diseases for Oncology, third edition, as print versions of ICD-O-3 do not include these changes and must be updated manually.

Corrections for both the soft cover and hard cover versions of ICD-O-3, and further discussion of issues that were not well-described in the print editions of ICD-O-3 can be found in:

You must use both sets of errata, Set #1 and Set #2, to have all of the corrections.
