TNM classification is the nomenclature that is used to describe cancer progression: T=Tumour, which has subcategories depending on the size; N=Node, which is the number of lymph nodes affected; M=Metastases, which describes how many other, secondary tumours have arisen since the primary tumour was detected. This nomenclature is standardized to ensure that clinicians worldwide use the same terms. This volume provides the international standard for the description of the anatomical extent of cancer to assist physicians in treatment planning and evaluation of results: prognosis; information exchange; and measuring changes in screening and patient care efforts. This pocket size book contains all of the information clinicians need to know to classify a tumour in any patient. New terminology is clearly marked so that owners of previous editions can see where changes have occurred in the classification.
