What Are The Stages of Mesothelioma Cancer Development?


” What Are The Stages of Mesothelioma Cancer Development?

Mesothelioma Cancer

One rare form of cancer is called Mesothelioma, a malignant tumor in the mesothelial tissues of the lungs and the abdomen, arising from the inhalation of asbestos. Because it is rare many people are unaware of this fatal disease. There are many people who go undiagnosed and die of Mesothelioma.  While there is a growing awareness of asbestos hazards  to health, too many people have not learned about Mesothelioma and therefore do not understand its cause, nature, signs and treatment. Today,  physicians find it difficult to detect Mesothelioma as its symptoms are similar to other lung diseases such as pneumonia and lung cancer. Moreover, it can take many years, decades, for a person exposed to asbestos to develop Mesothelioma.

Mesothelioma Awareness

Being unaware of Mesothelioma poses higher risks since it deters diagnosis and treatment. A person undergoing treatment must know the different stages of the cancer or the extent of the disease. Chances of recovering from Mesothelioma and the kind of treatment depend on the stage of the illness.

Mesothelioma Staging Systems

There are basically two staging systems used for Pleural Mesothelioma (lungs): TNM system and Brighan system. These staging systems are also used in other kinds of cancers; however, the first is commonly used. There is no established method in determining the stage of the Peritoneal Mesothelioma cancer (abdominal) so the TNM system is used.

The Mesothelioma TNM System

There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage 1 (one), the malignant Mesothelioma cells start to grow and multiply only one layer of the pleura. The pleura is the membrane that encloses the lungs and lines the wall of the chest cavity. However, there are some instances wherein the pericardium (membrane that covers the heart) and diaphragm cover are already affected. In this case, the cancer patient is still in stage 1 (one) Mesothelioma.

In the second stage, the two layers of the pleura are already affected by Mesothelioma. Take note, however, that in this stage, only one side of the body is affected. Normally, the pleura produces only small amount of lubricating fluid that allows easy expanding and contracting of the lungs. The excess fluid is absorbed by the blood and the lymph vessels so there’s a balance between the amount of fluid produced and removed. During the second stage Mesothelioma, fluid starts to build up between the membrane of the lungs and the membrane of the chest wall, resulting to pleural effusion. The increase in the volume of fluid produced causes shortness of breath and chest pain. Other Mesothelioma cancer patients experience dry and persistent cough. Diagnosis of the pleural effusion is achieved through a chest x-ray.

Stage 3 (three) Mesothelioma means that the malignant cells have already spread to the chest wall, esophagus and the lymph nodes on one part of the chest. The patient may suffer severe pain near the parts affected. When not treated immediately or when the Mesothelioma patient doesn’t respond well to medication, the cancer may advance to the fourth stage.

Stage 4 (four) Mesothelioma is formidable since at this stage the Mesothelioma cells have penetrated into the bloodstream and other organs in the body like the liver, the bones and the brain. The lymph nodes on the other side of the chest may also be affected by Mesothelioma in stage 4 (four).

The Mesotheloma Brighan System

Brighan staging system, on the other hand, determines whether the Mesothelioma can be surgically removed or not and whether the lymph nodes are affected or not.

Stage 1 (one) Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery.

Stage 2 (two) Mesothelioma, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells.

Stage 3 (three) Mesothelioma, the heart and chest wall are already affected; thus, surgery is no longer advisable. The lymph nodes in this stage, however, may or may not be affected.

Stage 4 (four) Mesothelioma, the final stage, cancer cells have already gone to the bloodstream and other parts of the body like the heart, brain, bone and liver. In most cases, a patient who has reached stage 4 (four) Mesothelioma only has four to twenty-four months to live.”
