Version 9 Frequently Asked Questions

AJCC Moved from Editions to Versions

The American Joint Committee on Cancer (AJCC) made an important change to how it updates and releases Cancer Staging content. The AJCC shifted from a Cancer Staging Manual to a Cancer Staging System and moved away from Editions to Versions. Updated Version 9 disease sites go into effect on January 1 following their release.
