What Are The Four Stages of Mesothelioma Cancer?

David Arnold Livingston


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.Its rarity is one of the reasons why a lot of people are not aware of this kind of fatal disease. In fact, many people die of Mesothelioma undiagnosed.Although there is now a growing awareness of the hazards of asbestos to health, still many have not heard of Mesothelioma and thus, have not understood its nature, cause, signs and
treatment. Even some physicians find it hard to detect Mesothelioma because its symptoms are akin to other diseases like lung cancer and pneumonia. Furthermore, it takes decades for a patient who was exposed to asbestos to develop Mesothelioma — fifty years, at most.

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. 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.


There are three variables in the TNM system: tumor, lymph nodes and metastasis. In the earliest stage of Mesothelioma, stage I, 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 I 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 III 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. The fourth stage 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 IV.

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. In stage I Mesothelioma, the lymph nodes are not yet affected and the patient can still recover through surgery. In stage II, surgery can still be executed but some lymph nodes have already been infiltrated by the cancer cells. In stage III, 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. In the final stage, stage IV Mesothelioma, 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 IV Mesothelioma only has four to twenty-four months to live.

Mesothelioma: More About this Asbestos Cancer

By David Arnold Livingston

Cancers and other forms of diseases are usually named according to the part of the body or the internal organ where abnormal growth of malignant cells takes place. In the case of Mesothelioma, the abnormal cells grow in the mesothelium, a surface cell layer that covers and
protects most internal organs. Normally, the mesothelium produces small amount of fluid in order to lubricate its layers—one of which directly covers the organ—and allow the movement of the organs, like the expansion and contraction of the lungs.

A Mesothelioma cancer patient’s mesothelium produces too much of this lubricating fluid, thereby damaging nearby tissues and organs. The most common form of Mesothelioma is Pleural
Mesothelioma, which begins in the Pleural or Peritoneum, the membrane that lines the chest cavity and covers the lungs.
About 2,000 cases of Mesothelioma have been noted yearly in United States. This is still a rare disease to consider, although the reported incidents have scalated in the past two decades. It has been observed and proven that heavy and long exposure to asbestos is the prime cause of Mesothelioma. Asbestos is a group of minerals in strong, flexible and fibrous form. It is used in industrial products such as cement, brake linings, textiles, electrical insulation, flooring products, chemical filters, fireproofing materials and others. This explains why most Mesothelioma patients are working in construction sites, shipyards and manufacturing companies of said industrial products.
Small asbestos particles float in the air and are either inhaled or swallowed by workers or persons within the vicinity. Aside from Mesothelioma, these people can acquire asbestosis, a non-cancerous chronic lung sickness and other forms of cancer of the lungs, cancer of the larynx and kidney.

Asbestos-related Mesothelioma comprise only 70 to 80 percent of the all the reported cases of the said cancer. There are reported Mesothelioma cases wherein the patients did not have any known exposure to asbestos. Some have been exposed only for a short period of time but still developed the cancer 20 to 50 years after the exposure, like in the case of a Mesothelioma cancer patient who only washed clothes that have been exposed to asbestos. Likewise, asbestos
fibers that have been stuck in the hair strands of a factory worker can also risk the health of others whom he lives with. It is therefore important for workers exposed to asbestos to change their clothes and take a shower before leaving the workplace to prevent his family members or companions from inhaling the asbestos particles and thus, from acquiring Mesothelioma.

The Mesothelioma cancer is slow-forming. That’s why one develops the cancer so many years after the exposure to asbestos. Some develop the cancer fifty years after the exposure, which makes it hard to determine whether the person has Mesothelioma or not, especially when the patient has no knowledge of the exposure to asbestos.
Moreover, malignant Mesothelioma shows signs similar tothose of other ailments such as pneumonia. Symptoms of Pleural Mesothelioma also evident in other illnesses include: shortness of breath, persistence of cough, weight loss and chest pain. Peritoneal Mesothelioma, which affects the abdominal cavity, is indicated by swelling of and pain in the abdomen, weight loss, bowel obstruction, anemia, blood clotting abnormalities and fever.

Complete physical examination is needed to make sure one has Mesothelioma cancer. This includes xrays of the body part where the symptoms are felt or seen, CT scan and MRI. To confirm Mesothelioma, a biopsy is also performed by a surgeon or oncologist (a physician who
is specializing in the diagnosis and treatment of a cancer). The sample tissue removed by the surgeon is examined by the pathologist. Once confirmed, the doctor then finds out the extent of the cancer, which is crucial to the treatment of Mesothelioma. Although malignant, Mesothelioma when earlier diagnosed can still be treated. Most Mesothelioma patients undergo surgery, radiation therapy and chemotherapy.
