Know About TNM Staging System: A Stage of Breast Cancer

 

A Brief Overview of the TNM Staging System

In order to describe the extent of damage caused by cancer in a particular person, the TNM staging system should be used. The acronym in this cancer staging system stands for tumour, lymph nodes and metastasis. Since being devised by Pierre Denoix in the 1940’s and 1950’s, the system has grown in use and it currently stands as a popular choice among doctors and health professionals in dealing with patients suffering from cancer. The system had gone through several developments in the past to improve its diagnosis capabilities. It’s now very effective in providing details about how cancer behaves and operates in a particular patient.

The Main Uses of the TNM Staging System

Know About TNM Staging System: A Stage of Breast Cancer 1) It aids doctors and medical practitioners in determining which stage the tumour should be classified in. This significantly helps them in coming up with a comprehensive and informed treatment plan. This is very important because various stages of the illness require various treatment plans. So it’s absolutely necessary that the medical staff should be as accurate as possible when identifying the cancer’s stage.

2) It provides an indication of prognosis. A prognosis is a medical term used to the predictions that doctors make based on the current state of a patient suffering from cancer. For example, a doctor can make the prognosis that a particular patient has only several months to live. Medical doctors can make these predictions only when they have subjected a patient through the TNM staging system.

3) It assists in the evaluation of treatment results. For this to happen, the patient should undergo two or more times through the staging system. The results will then be compared between two measurements to determine if the treatments have been effective or not. In essence, the TNM staging system can also be used to find out the effectiveness of certain cancer treatment procedures.

4) It allows cancer facilities from all over the world to collaborate and gather information in a more productive manner. This will ultimately open doors to better cancer research and hopefully more effective treatment procedures.

The Parameters of the TNM Staging System
1) The T parameters- This refers to the size or the extent of the diagnosed primary tumour. It can be either TX, Tis, T0, T1, T2, T3, or T4. TX means that the tumour cannot be evaluated. Tis means the cancer has not spread or has not invaded the surrounding tissue. T0 means there’s no signs of any tumour. And T1 to T4 refers to the sizes and extents of the tumour.

2) The N parameters – This refers to the degree of expansion of the tumour to regional lymph nodes. The degrees are as follows: Nx, N0, N1, N2, and N3.

3) The M parameters – This refers to the presence of what’s called distant metastasis. If the staging system registers a M0, this means that there is no distant metastasis. However, if the staging system says M1, this means that there’s a presence of distant metastasis in organs that are beyond the lymph nodes.

In conclusion, the TNM staging system is a very valuable and effective tool which should be used by more medical doctors and facilities.
