Solid Tumor Breast Rules

The final 2018 Solid Tumor Breast Rules have been posted and must be used for cases diagnosed 1/1/2018 forward. IMPORTANT INFORMATION: Major changes have been made to the 2018 Breast rules regarding histology coding. These comprehensive changes reflect WHO 4th Edition Breast Tumors and the 2018 In Situ Breast CAP Protocol and Invasive Breast Carcinoma CAP Protocol. The editors of the 2018 Breast rules strongly recommend you read the Breast Terms & Definitions AND the Breast H Rules as they provide detailed instructions for coding breast histologies.

Educational modules are being developed for each revised set of site rules and an email notice will be sent once they are available. Please direct questions concerning the breast rules to Ask A SEER Registrar.
