Mesothelioma Cancer

by Ivan Chia

Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. Diagnosis begins with a review of the patient’s medical history, including any history of asbestos exposure. A complete physical examination may be performed, including x-rays of the chest or abdomen and lung function tests. A CT (or CAT) scan or an MRI may also be useful. A CT scan is a series of detailed pictures of areas inside the body created by a computer linked to an x-ray machine. In an MRI, a powerful magnet linked to a computer is used to make detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed.

A biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity. If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.

If the diagnosis is mesothelioma, the doctor will want to learn the stage (or extent) of the disease. Staging involves more tests in a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment.

Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs.

The most critical form of mesothelioma is the malignant form. Known as malignant mesothelioma, the primary causal factor is asbestos infection. According to the US National Cancer Institute, “Malignant mesothelioma is a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium).”

Mesothelioma can be classified into three types – pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. Pleural mesothelioma refers to a cancer of the lining of the lung (pleura), peritoneal mesothelioma refers to a cancer of the abdominal cavity (peritoneum) lining, and pericardial mesothelioma is a cancer that occurs in the lining that surrounds the heart (pericardium). The subtypes of mesothelioma are of three basic types, one very aggressive, one least aggressive, and one lying between the two extremes.

Malignant mesothelioma can be diagnosed through several imaging techniques. These imaging techniques enable physicians to assess mesothelioma. Once mesothelioma is suspected, patients are advised to undergo several tests, like X-ray, Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI) scans, and Positron Emission Tomography (PET) imaging. The physician may also like to undertake special mesothelioma tests like thoracoscopy, peritoneoscopy and biopsy.

Learning about the stage of mesothelioma is a critical factor that helps physicians to decide the treatment plan. If the cancer is confined to the pleura, mesothelioma is considered localized. If the cancer spreads beyond the pleura and to other parts of the body such as the lungs, abdominal cavity, lymph nodes and the chest wall, mesothelioma is considered to be in an advanced stage.

The oft used and the oldest system for determining the stages of mesothelioma is the Butchart System. The Butchart System is based on the extent of the primary tumor mass available in a patient. This system divides mesothelioma into four stages. The TNM system, a slightly advanced system over the Butchart System, determines staging through variables of tumor in mass and the spread, the lymph node involvement and metastasis. However, the latest system is known as the Brigham System, where staging is done as per the respectability and lymph node involvement. In spite of such modern techniques, a definitive diagnosis of mesothelioma still remains possible through fluid diagnosis and tissue biopsy.

Qualified medical professionals perform mesothelioma diagnosis. A wide range of tests and procedures are done to find out whether the disease is present. Mesothelioma diagnosis is a difficult procedure as the symptoms of mesothelioma are very similar to other benign diseases. This coupled with the fact that mesothelioma has a huge latency period makes patients and their doctors dismiss the symptoms of mesothelioma as signs of ageing. Only after detailed testing because of recurring symptom mesothelioma is confirmed.

Review of medical history of patient

The medical history of the patient will be reviewed in the first place. This is because the doctor will need to determine the extent and the severity of the risk factors and the symptoms of mesothelioma. Also, the doctor can find out the nature of asbestos exposure of the patient, how long and how much they were exposed. One another point the doctor will want to know is whether you were a smoker or not. This is because smokers have a higher risk of contracting mesothelioma as compared to non-smokers.

The doctor will also conduct some preliminary examinations to determine the type of mesothelioma. This can be found out by checking for fluid. When fluid is found in the chest. It is a case of pleural mesothelioma. When fluid is in the abdomen, it is a case of peritoneal mesothelioma and when fluid is in the heart, it is a case of pericardial mesothelioma.

Diagnostic tests:

CT scans, x-rays and MRIs are very useful in determining the spread of the cancer. These diagnostic image tests help to determine the stage of mesothelioma. All the methods are very useful and they help in making a more detailed diagnosis. The CT scans help in getting a 3D view of the inside body parts. Thus, the same part can be viewed from various angles. Unlike x-ray, MRI uses magnetic fields to view the body parts.

Testing fluid and samples of tissues:

In case of mesothelioma, fluid may build up in chest, abdomen or heart. In such cases, the medical professional will take a sample of this fluid and test it. The sample will be drawn via a long needle and then, it will be tested in a laboratory. The doctor in certain cases of mesothelioma may also prescribe a bronchoscopy procedure. Sometimes, certain tissue samples may be taken to perform further testing. Persons having lung cancer or pleural mesothelioma may also have lymph nodes affected by the disease. These patients may be advised to undergo a mediastinoscopy. This procedure helps the doctors to find out how far the disease has affected the lymph nodes. This will help in a better diagnosis of mesothelioma. It will also help in determining the stage of mesothelioma.

Diagnosing mesothelioma is a very complex procedure involving a lot of steps. While the first symptoms are completely misleading, the later symptoms are also not conclusive. Fluid build up in the body organs alone is not a sign of mesothelioma. Only specialized medical personnel in highly specialized laboratories can correctly determine mesothelioma. This is the reason why many mesothelioma cases go undocumented. It is necessary that all countries fund and encourage their researchers and medical professionals to find an easy and simple diagnostic procedure for mesothelioma.

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 is a serious and very aggressive form of cancer.

People who have mined asbestos, manufactured asbestos products, installed asbestos insulation, or removed asbestos may be at risk for developing mesothelioma. In addition, family members of those who have worked with asbestos, people who have lived near asbestos mines or processing plants, or anyone who has inhaled asbestos fibers may also be at risk for developing mesothelioma.

There are a range of tests and procedures used to diagnose mesothelioma. X-rays, CT scans, and/or MRI scans are performed to determine the presence of mesothelioma. If there is a positive indication of mesothelioma, or if further testing is still needed to determine the presence of mesothelioma, the scans are followed-up with a needle biopsy or an open biopsy.

Treatment options for mesothelioma vary according to age, overall health, location of the disease, and extent of the disease. Surgery, radiation therapy, and chemotherapy, alone or in combination, are standard treatment options for mesothelioma. Experimental treatments, such as those used in clinical trials, may also be an option.

Mesothelioma is a form of cancer that could have been prevented and is not the fault of the victim, but the fault of the companies that did not protect workers or others against the hazards of asbestos. Financial security for victims and their families, including compensation of medical expenses, pain and suffering, burial expenses, and after-death stability for families afflicted, may, therefore, be accessible through the law.

There are many different types of support groups, as well, available to mesothelioma patients and their families including formal groups that focus on learning about mesothelioma or dealing with feelings, informal groups, social groups, groups only for those with mesothelioma, and groups for those with mesothelioma including family members and friends. Hospitals, doctors, nurses, and other healthcare workers have, or can obtain, a listing of such groups within your local area.

The industry, the asbestos caused much suffering to many families in violations of the striking evidence that the risk from asbestos is dangerous and often deadly. The suffering could have been prevented, because the asbestos companies knew a lot more than that to the public on the subject. The companies, the protection of the industry is larger than the lives of their employees.

Back in the years 1920, a large number of medical have shown that the scars on the lungs, the asbestos workers of the company. This evidence was shown during the autopsy of workers. Asbestos companies had knowledge of it, but he has chosen to ignore the facts, because the reaction of the audience at this information would kill the industry of asbestos.

Further studies in 1930 have shown that the asbestos and youth protection workers of the company were in fact dying of lung diseases and cancer. There was sufficient evidence to secure an undeniable link between exposure to asbestos and development of mesothelioma. Unfortunately, the companies agreed that the overwhelming evidence and in a series of letters between asbestos. In this letter, the State and Heads of Government have demonstrated the extent to which the company is prepared to go to secure their own interests to protect. These letters were distributed, in the years 1930, the so-called “Sumner Simpson Papers.” In these words, the asbestos some executives were statements such as “the less as asbestos, we are better. 1940, tries to prove that asbestos exposure was harmless to save, and The industry of asbestos. Studies have shown that the exact opposite. They have shown that the risk from asbestos is in fact quite harmful, or even fatal. On the basis of these studies, which tried to force scientific societies, to change their conclusions.

Asbestos had full knowledge of the possible damage caused by asbestos exposure. The scientists, and studies have confirmed that there is a direct correlation between exposure to asbestos and an early death. Asbestos companies first try, the knowledge and the silence of the scientists who conducted the study, the harmful effects of asbestos exposure. Once the information on asbestos is ripe for the public, these companies have tried to deny that knowledge is simply that the people are working for products, which contain asbestos, are suffering. The companies have denied knowledge of the disputes. The mere fact of the matter is that the products that contain asbestos, often cause serious injuries and deaths. For this reason, the mesothelioma very valuable and are not frivolous. Lung disease, lung cancer and mesothelioma all come from the asbestos exposure. Many lives could be saved if the companies that asbestos were prepared to communicate information they have access to.
