Diagram showing the T stages of bladder cancer

The TNM Classification of Malignant Tumours (TNM) is a cancer staging notation system that gives codes to describe the stage of a person's cancer, when this originates with a solid tumor.

The TNM staging system 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. It has gained a wide degree of international acceptance for many solid tumor cancers, but is not applicable to diffused cancers such as leukaemia and is of limited use for other cancers such as diffuse lymphoma and ovarian cancer.
