The TNM stage system

The TNM stage system is used to describe the extent to which prostate cancer has developed and spread.

Details about staging classifications are described clearly in Assoc. Prof. Prem Rashid's excellent book "Prostate cancer - your guide to the disease, treatment options, and outcomes (3rd edition published in 2010 by Uronorth Group). On page 66 of that book the TNM system is described. That page can be downloaded from our web site
