The Neoplasm Classification consists of over 130,000 different terms for neoplasms arranged by synonymy (i.e., concept identifier) and by developmental lineage. The 130,000+ terms are distributed among approximately 5,800 different neoplasm concepts. The Neoplasm Classification has been described in a freely available BMC journal article.
Each classified neoplasm terms is designated by a code identifier consisting of the letter "C" followed by a 7 digit number.
In addition to (and following within the file) the list of classified neoplasm terms are the following supplemental lists:
- a list of unclassified cancer related terms (all identified by the same identifier, "C0000000")
- a list of unclassified terms of precancers (all identified by the same identifier, "C0000001")
- a list of classified medical syndromes associated with the co-occurrence of neoplasms in some cases, and designated by an identifier consisting of the letter "S" followed by a 7 digit number.
- a list of classified staging terms for neoplasms, each designated by an identifier consisting of the letter "ST" followed by a 7 digit number.
The total number of cancer-related terms in the file exceeds 146,000. To the best of my knowledge, this exceeds the size of any other cancer nomenclature by over 10-fold.
In June, 2014, my book, entitled Rare Diseases and Orphan Drugs: Keys to Understanding and Treating the Common Diseases was published by Elsevier. The book builds the argument that our best chance of curing the common diseases will come from studying and curing the rare diseases.
I urge you to read more about my book. There's a generous preview of the book at the Google Books site.
