Secretory carcinoma of breast of breast

  • Concept ID44502032
  • Concept code8502/3-C50.9

Is this correct “of breast of breast”. It is not that way in ICD-O-3 or anywhere else that I can find via Google

I see other ICD-O codes that appear redundant. “of bone of bone”, of bone of mandible". Mandible is a bone.

This happens because we combine ICD-O morphology (ductal carcinoma of breast) with topology (breast). In this case, the word “breast” is not only part of the topology, but also morphology. We will have to add another cleaning step to remove those situations. Thanks for the catch.
