pTNM

What does pTMN mean?

TNM stands for Tumour, Nodes, Metastasis. TMN is an internationally recognized staging system originally created by the American Joint Committee on Cancer. A TNM stage will be included in your pathology report if you have been diagnosed with cancer.

The TNM uses information about the tumour (T), lymph nodes, (N), and metastatic disease (M) to provide an overall cancer stage. The ‘p’ means the information was provided by your pathologist after examining your tissue sample under the microscope.

The TNM staging system provides important information about how the disease with behave over time (prognosis). Your treating doctors will combine the information in the pTNM with other medical information to determine your overall stage and plan your care.
