List of MeSH codes (C18)

MeSH (Medical Subject Headings) codes are a comprehensive controlled vocabulary used by the National Library of Medicine (NLM) for indexing, cataloging, and searching for biomedical and health-related information. The "C" category within the MeSH hierarchy represents Diseases. Within the C category, "C18" specifically refers to Neoplasms (also commonly known as tumors or cancers).

Therefore, a List of MeSH codes (C18) is an extensive compilation of specific MeSH terms that describe different types of neoplasms. This list is hierarchical, meaning that it includes both broad categories of cancers and more specific subtypes, allowing for precise indexing and retrieval of relevant medical literature.

Using C18 MeSH codes is crucial for:

• Indexing medical literature: Indexers at NLM use these codes to tag articles in PubMed and other databases, ensuring accurate retrieval.
• Searching medical literature: Researchers can use these codes in PubMed and other databases to find articles specifically about particular types of neoplasms.
• Standardizing terminology: The controlled vocabulary ensures that different researchers use the same terms to describe the same diseases, improving communication and collaboration.
• Data analysis: Researchers can use MeSH codes to analyze trends in cancer research and treatment.

The complete and most up-to-date List of MeSH codes (C18) is available on the NLM website and within the MeSH browser. The list is regularly updated to reflect new discoveries and changes in medical knowledge. This list is organized hierarchically, offering increasing specificity as one navigates deeper into the tree structure. This structure allows users to find the most accurate term for a particular neoplasm based on its location, histology, and other characteristics.
