Mesothelioma Cancer

by Pius Ephenus

Diagnosis mesothelioma is a scary subject you don’t want to talk or hear about. It is a heart wrenching news for you and your family. But fortunatelly, over the years scientist has been able through research to detect and treat mesothelioma. There are a lots sites online filled with helpful informations. There are also support groups and help mechanisms put in place for every stage of this dreadful disease. Mesothelioma disgnosis does not guaranteed a grim prognisis; therefore, in most cases early detection of the disease as with any cancer is important so that it can be treated early.

Simply put, the diagnosis of mesothelioma is the first step on a road to discovery. There are many websites to aid in the publics’ research of mesothelioma and the warning signs that lead to early diagnosis and subsequently the blessing of early treatment. It is common to treat a diagnosis of mesothelioma with surgery and chemotherapy or surgery, chemotherapy and radiation. Mesothelioma is also known as the asbestos cancer. Mesothelioma shows subtle variations from asbestosis or asbestos pleural disease. Regardless it is highly recommended if you have worked around asbestos in anyway or form that you are checked for mesothelioma on a regular basis. Early diagnosis is imperative. Some of the varied warning signs include shortness of breath as well as pain in the lower back or pain at the side of the chest. Others signs may include hoarseness, difficulty swallowing or sweating and fevers.

Prognosis defers significantly among people that have been disgnosed with mesothelioma and this depends on a number of factors. These causes have a significant impact on the speed of recovery; the size of the cancer, what part of the body it is found, and how far it has spread. And also, how the cancer cells looks under the microscope, and their respond to treatment as well as the age of the patients has direct bearings on recovery time.

There are legal issues involved with a diagnosis of mesothelioma. There are several lawsuits against companies whose employees were exposed to asbestos. These are definitely matters to be researched if you are among the individuals who qualify involvement in a lawsuit. If you are uncertain whether you qualify, you can simply fill out an online form and an attorney will be happy to talk with you. It is not necessary but there are good reasons to acquire an attorney who is knowledgeable in mesothelioma litigation.

There are speciality lawyers and law firms for mesothelioma cases. Most of these specialized attorneys have an impressive settlement record and successes in obtaining verdicts in the courtroom as opposed to settlements out of court. As in most cases, there is money to be dispersed though the monetary value of the settlements are not as important as the impact lawsuits like these will eventually make in the safety issues surrounding workplaces where potentially harmful chemicals can be inhaled or absorbed into peoples bodies.

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.

Malignant mesothelioma detection, like other cancers, can be accomplished with imaging equipment, such as x-ray machines. But once detected, mesothelioma diagnosis is difficult for a number of reasons. First, there is a very extended time period between the exposure to asbestos and the onset of the disease, sometimes as long as 50 to 60 years. Patients would often not think to tell their doctors about working in an asbestos-related job many years earlier.

Second, the typical symptoms of mesothelioma, shortness of breath and coughing, are also symptoms of many other types of lung problems, both cancerous and non-cancerous. Thus, just because a person has these symptoms, it does not in any way provide a mesothelioma diagnosis.
Third, many types of tumors can exist in the serous cavities that are not mesothelioma. These other types of tumors can be non cancerous, or benign, that originate in the tissues of the serous membranes, other than the mesothelium. Or they can be tumors that have migrated from other organs with cancerous growths due to metastases.
Mesothelioma and Imaging Technologies
X-rays and other types of imaging technologies can be used to detect tumors or effusion (build up of fluid) in the body, including mesothelioma detection. A growth in the chest cavity will show up in an X-ray or MRI analysis. But these devices cannot directly determine the type of cancer or provide a mesothelioma diagnosis. They cannot determine whether the tumor is mesothelioma or originates from some other source.

Positron emission tomography (PET) is a type of diagnostic imaging scan that is used for malignant mesothelioma detection. PET scans use the emission of positrons (tiny particles that are emitted from radioactive substances) for the purpose of radiation detection.
Some medical professionals are of the impression that PET scans are the most effective method through which to definitively verify a case of mesothelioma. While they believe that standard imaging techniques like x-rays and MRIs should continue to play a role in diagnosing the disease, it is felt that positron emission tomography is becoming an increasingly valuable tool in the staging and typing of the latent asbestos cancer.
Diagnostic Surgery – Biopsy
To provide a mesothelioma diagnosis, a biopsy is needed. This biopsy then undergoes what is called diagnostic histopathology. Histopathology is a technique where the cells from the tumor are viewed under a high-powered microscope, or electron microscopy. Electron microscopy is considered the gold standard for evaluating tumor material from a biopsy. It is a highly advanced microscope that allows viewing of the tiniest elements of cell tissue.
For mesothelioma diagnosis, a pathologist (a doctor who specializes in disease detection) places the tumor cells in the electron microscope and then views the structure of the individual cells. The mesothelioma cells have a specific shape and pattern, and this allows them to be identified by a very keen pathologist. But mesothelioma cells also look similar to other types of cancer cells, such as adenocarcinoma cells, and this can make the pathologist’s job very difficult. Even with the electron microscope, the different types of mesothelioma cells can be hard to recognize. The three types of cells are epithelioid mesothelioma cancer cells, which are tubular in shape, sarcomatoid mesothelioma cancer cells, which are oval and irregularly shaped, and biphasic mesothelioma cancer cells, which are a combination of shapes. These cells can be confused with other types of cancer cells.
New Methods For Mesothelioma Detection
Due to this diagnostic confusion, much research is underway to find new methods for diagnosis. One method is to evaluate the types of compounds generated by the mesothelioma cancer cells. This is called histochemistry. Histochemical reactions have long been used to distinguish between mesothelial and other types of tumor cells. For example, mesothelial cells are known to produce specific types of carbohydrate compounds. Unfortunately, other types of cells in the body also produce these compounds.
Immunochemistry is also being used to detect mesothelioma. This area of study evaluates the presence of antibodies in the body. Certain types of antibodies are known to be associated with certain types of cancer. But mesothelial cells have no specific types of antibodies that can provide a “positive” marker. Consequently, immunochemistry allows the doctor to “eliminate” the other cancers, but does not indicate the presence of mesothelioma. These techniques offer insight into the disease and may help eliminate other diseases, but none can directly detect mesothelioma.
New Blood Tests for Mesothelioma Detection
SMR Protein: Recently, because of the difficulty in diagnosing malignant mesothelioma, research has concentrated on finding new ways to detect the presence of the disease. Researchers in Australia have found that a certain protein, called SMR or Soluble Mesothelin Related protein, is elevated in patients with mesothelioma. These researchers have suggested that a test for the presence of SMR in the blood could represent a useful marker for the diagnosis and disease progression. They feel that such a diagnosis tool could lead to earlier detection, and thus more effective treatment.
One of the most striking findings of their research was that several asbestos-exposed persons who tested positive for SMR were diagnosed with mesothelioma within three years. They suggested that evaluation of SMR may help to identify persons at risk for this deadly disease. Also, they found that SMR levels increase as mesothelioma progresses, suggesting that SMR evaluation could be used to track the progression of the disease and the effectiveness of treatment
Osteopontin Glycoprotein: In an effort to produce the first early-detection test to screen for malignant mesothelioma, researchers at Wayne State University have been studying the possible link between mesothelioma development and levels of a glycoprotein called osteopontin. Early clinical study findings of 190 patients have demonstrated a link between high levels of osteopontin and the development of malignant pleural mesothelioma.
Although the results are being viewed as preliminary, there is a great deal of excitement surrounding the potential of a blood test capable of screening for mesothelioma in its earliest stages. While there is no known cure for malignant mesothelioma, research is ongoing and certain successes have already been realized in terms of extending survival time beyond the one to two year post-diagnosis average. It is hoped that if mesothelioma specialists have more time through which to conduct treatment on a lesser developed form of the asbestos cancer, the greater a patient’s chance at potential survival.
Despite the fact that the preliminary results of the osteopontin blood test clinical trial have been met with some controversy, the National Cancer Institute (NCI) continues to sponsor additional study.
Tell Your Doctor About Asbestos Exposure
If you or a loved one has been exposed to asbestos, even if it was in the distant past, it is very important that you inform your doctor. One reason why mesothelioma is such a deadly disease is that it is detected late in the disease process. If your doctor knows of the exposure, he or she may be more aware of your symptoms or other health issues that could be used for early detection.

Cancer is a disease related to the uncontrolled growth of tissue, leading to the accumulation of mass (called a tumor or lesion.) Normal cells in the body divide and grow in an orderly controlled manner. When cells grow uncontrollably and this growth invades other tissues or organs, the growths are called malignant or cancerous. When a mass of tissue, or tumor, is benign, it is relatively stable and does not invade other tissues.

Cells from malignant tumors can break away and travel to other parts of the body, usually through the bloodstream, but also through the lymph system. When these cells find new host organs, these cells can grow into tumors in the new tissue. This spreading process is called metastasis and when a cancer has reached an advanced stage to where the malignant cells are attacking other organs, it is said that the cancer tumors have metastasized. The tumors in new organs are always made up of cells similar to those of the original tumor.
Benign tumors do not metastasize. They can often times be removed through surgery and not re-occur.
Lung Cancer
Lung cancer occurs when lung tissue develops cancerous growths. Primary lung cancer is cancer that originates in the lung tissue. Secondary lung cancer is cancer that spreads, or metastasizes, from other organs.
Primary Lung Cancer
There are several different types of primary lung cancer. These are divided into two main groups:
Small Cell Lung Cancer
Non-small Cell Lung Cancer

Pleural mesothelioma is often thought of as a third type of primary lung cancer. However, it is not a lung cancer. Mesothelioma does not develop in the lungs, but in the serous membranes surrounding the lungs. As such, it does not fall into the typical categories of lung cancer. Mesothelioma can also occur in other tissues, in the lining of the abdomen, call peritoneal mesothelioma, and in the lining of the heart, pericardial mesothelioma.
Small Cell Lung Cancer
Small Cell Lung Cancer comprises approximately 20% of the primary types of lung cancer. It is called small cell cancer because the tumor cells are very small, with the cells containing almost exclusively the cell nucleus and nothing more. This type of cancer is also referred to as “oat cell” cancer. Chemotherapy is often suggested for this cancer in the early stages because of the rapid way it which it spreads. Surgery is not a good option to stop the spread early on. This type of cancer is most closely linked to smoking; non smokers rarely have it.
Non-Small Cell Cancer
Non-small cell cancer falls into these categories:
Squamous cell carcinoma
Adenocarcinoma
Large cell carcinoma
Adenosquamous cell carcinoma
Undifferentiated carcinoma
Each category of non-small cell cancer are physiologically similar and they respond to treatment differently than to small cell lung cancer.
Squamous cell carcinoma is a common type of primary lung cancer. This type of cancer is also linked to smoking and it develops from the cells than line the airways in the lungs. Squamous cells are thin, flat cells that look like fish scales. Commonly the tumor growths are located in the center of the lungs near the large airways (bronchi). It is also referred to as epidermoid carcinoma. It comprises approximately 30 to 35% of the non-small cell cancer in the US, affecting men and the elderly most frequently.
Adenocarcinoma, like squamous cell carcinoma, develops from tissues in the lung airways. But, it develops from the glandular secretory tissues. (tissues that produce mucus). It is often found in the outer airway passages, not the main bronchi, like the squamous cell variety. The incidence of this cancer is increasing. It comprises about 40% of the non-small cell lung cancer in the US and is the most common lung cancer among women.
Large cell lung cancer is named after its appearance. The cells look large and unnatural under the microscope. These types of cells grow quite quickly.
Adenosquamous carcinoma are cells that appear flat under the microscope, like the squamous cells, but derive from the glandular secretory cells, like the adenocarcinoma.
Undifferentiated carcinoma includes cancer cells that cannot be identified as one of the other groups. The cells appear abnormal under the microscope and multiply uncontrollably.
Secondary Lung Cancer
Secondary lung cancer is cancer that has spread to the lungs from other organs. Many different types of cancer spread to the lungs, because of its very high blood supply. These include breast cancer and colon cancer.
The type of cancer is very important when it comes to treatment. The different types of cancer cells respond differently to different types of chemotherapy and other therapies. When cancer cells spread from other organs to the lungs, then the lungs have to be treated for the other type of cancer, not lung cancer. This is an important distinction. For example, breast cancer that spreads to the lungs, has to be treated for breast cancer, not lung cancer.

Malignant mesothelioma is generally divided into three histological categories, or types of cells: epithelioid, sarcomatoid and biphasic mesothelioma. Within each of these mesothelioma cancer cell types, subtypes exist. Many mesothelioma patients display more than one cell type.

The diagnosis of mesothelioma cannot be specifically by lung x-rays or other types of imaging, because many different types of cancer can be present in the lungs. The images show only that a tumor may be present, but does not provide an indication of whether the tumor is mesothelioma. A biopsy must be performed where the mesothelioma cancer cell types are used to distinguish mesothelioma from other types of cancer, such as lung cancer.
Epithelioid Mesothelioma Cancer
Epithelioid mesothelioma is the most common cell type, constituting approximately 50% to 70% of all malignant mesothelioma. These cells are relatively uniform in shape and have a tubular pattern with a distinct cell nucleus. The individual cells are shaped like cubes or multi-sided boxes.
Because of the similarity between adenocarcinoma and mesothelioma cancer cells, they are often confused and mesothelioma can be misdiagnosed. Inspection of the cancer cells under high-powered microscopes and identification of unique characteristics of the chemical properties of the cells can help make the proper diagnosis. Learn more about epithelioid mesothelioma cancer.

Sarcomatoid Mesothelioma Cancer
Sarcomatoid mesothelioma is the least common type of mesothelioma cancer cell and accounts for approximately 10% to 15% of malignant mesothelioma. These cells typically have more of an oval, irregular shape and the nucleus of each cell is not as visible with a microscope as the epithelioid mesothelioma cancer cells. Because of the similarity of appearance, the sarcomatoid cancer cells can also easily be confused with the more typical sarcoma cancer cells. Learn more about sarcomatoid mesothelioma cancer.
Biphasic Mesothelioma Cancer
Approximately 20% to 40% of the mesothelioma cancer cells fall into the biphasic category, which is combination of the sarcomatoid and epithelioid types. The biphasic type can occur with the two types of cells intermixed continuously throughout the tumor, or with them in specific groupings. Transitional areas between the two cell types are often present. Learn more about biphasic mesothelioma cancer.
Prognosis Based on Cell Type
The mesothelioma cancer cell type does affect the prognosis. A study conducted on 167 patients showed that patients had the following mean survival times:
epithelioid
8.5 months
sarcomatoid
7 months
biphasic
6 months
Treatment options are very similar for patients with the different cell types.

Asbestos is a natural state, the mineral fibers in the soil and mines in the world. It is so small that it can not be identified under the microscope. In the past, asbestos in a variety of products such as insulation to increase the flame-retardant properties. Exposure to asbestos, particularly the extension of the duration was associated with mesothelioma and other health problems, including lung cancer. The Mesothelioma is a rare form of cancer, the cells in the wall of the chest and abdomen. The substances in these areas, the mésothélium, and they produce a liquid lubricant, the institutions, easily and without irritation, or a wound in the chest cavity.

Asbestos fibers are on the wall of the lungs or other parts of the respiratory tract and to stay there forever. Asbestos is extremely dangerous if they are in the air. The fibers are smaller and lighter and can remain afloat for a long period and can move, which is very far from their source. Since the asbestos fibers in the air and microscopic, people can breathe asbestos fibers over many years without being aware of that. The workers in environments where the materials for the construction, in particular, the isolation, which treats are most at risk. Already in the years 1940, the workers, the risk to ignore, and deals have been suspended, the large quantities of asbestos, often for long periods of time. Occupations that are particularly affected by the high exposure to asbestos are in related fields such as mining, milling, manufacturing of asbestos tiles, and in the manufacture of products that used asbestos. The other sectors with high risks involved as possible, shipbuilding, construction, maintenance and repair of motor vehicles and any form of destruction. Today, asbestos exposure has been reduced because of the system of government. Still, however, is the démolisseurs are at risk if they damage obsolete asbestos in the old structures. This can be from 10 to 40 years for the symptoms of a disease with asbestos on the surface.

Critics have claimed that the manufacturers of asbestos knew of the dangers of asbestos exposure many years prior to warn the public about the risks to health. Despite the dangers of asbestos, substance, which is still found in thousands of products today. Because of their mobility in the air, its size and microscopic characteristics harmful, professional help is necessary in order to remove the asbestos. There are specialists to reduce services, which make it possible to withdraw asbestos, houses or other buildings. Asbestos is harmful if the structure, he is disturbed that the release of asbestos fibers into the air.

Some observers say that the responsibility asbestos relative to a product have led to more than 100 billion US dollars for claims, and more than 100 companies in bankruptcy.
