TNM staging an international standard for the staging of tumors; the systems of the American Joint Committee on Cancer and the International Union Against Cancer are now identical. Staging is according to three basic components: primary tumor (T), regional nodes (N), and metastasis (M). Subscripts are used to denote size and degree of involvement; for example, 0 indicates undetectable, and 1, 2, 3, and 4 a progressive increase in size or involvement. Thus, a tumor might be described as T1N2M0. See also cancer.

TNM stag·ing

(stāj'ing)
A system of clinicopathologic evaluation of tumors based on the extent of tumor involvement at the primary site (T, followed by a number indicating size and depth of invasion), and lymph node involvement (N) and metastasis (M), each followed by a number starting at 0 for no evident metastasis; numbers used depend on the organ involved and influence the prognosis and choice of treatment.
