The<unk>  Classification of Malignant Tumors <unk>  is a globally recognised standard for classifying the extent of spread of cancer. It is a classification<unk>  of the anatomical extent of tumor cancers. It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia and tumors of the central nervous<unk> . Most common tumors have their own<unk>  classification. Sometimes also described as the AJCC<unk> .<unk>  was developed and is maintained by the Union for International Cancer Control (UICC).

In 1987, the UICC and AJCC staging<unk> s were unified into the single<unk> .<unk>  is a notation<unk>  that describes the stage of a cancer, which originates from a solid tumor, using alphanumeric codes: *T describes the size of the original (primary) tumor and whether it has invaded nearby tissue, *N describes nearby (regional) lymph nodes that are involved, *M describes distant metastasis (spread of cancer from one part of the body to another). The<unk>  for all solid tumors was devised by Pierre Denoix between 1943 and 1952, using the size and extension of the primary tumor, its lymphatic involvement, and the presence of metastases to classify the progression of cancer.
