What is the TNM system for prostate cancer stages?

ANSWER

As they do for most cancers, doctors use the TNM system of prostate cancer stages. The prostate cancer stages are described using three different aspects of tumor growth and spread. It’s called the TNM system for tumor, nodes, and metastasis:

T -- for tumor -- describes the size of the main area of prostate cancer.

N -- for nodes -- describes whether prostate cancer has spread to any lymph nodes and to what extent.

M -- for metastasis -- means distant spread of prostate cancer, for example, to the bones or liver.

There are other ways of classifying prostate cancer, such as the Gleason system. Sometimes, the TNM system and Gleason score are combined together to describe prostate cancer stage.
