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, 2025 following their release.
