How to diagnose mesothelioma?

by Archana Sarat

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.

Not Only Asbestos Causes Mesothelioma Lung Cancer

Mesothelioma lung cancer is usually associated with asbestos exposure. In fact there are many other risk factors that cause mesothelioma cancer. One of them is the erionite. Erionite is a naturally occurring fibrous mineral that belongs to a group of minerals called zeolites. Zeolites are hydrated aluminosilicates of the alkaline and alkaline-earth metals.
Erionite was used in the past as a noble metal-impregnated catalyst in a hydrocarbon-cracking process. It was studied for use in fertilizers and to control odors in livestock production, because of its ability to selectively adsorb molecules from air or liquids. In many countries erionite blocks were used (and may be are still used) as building material or in stucco pastes and whitewash.
Erionite was mentioned for the first time as a mesothelioma lung cancer risk factor in 1975, when Turkish government presented a study that uncovered a high incidence of a rare malignant mesothelioma in lung tissues of people in certain small villages in the Cappadocia area in Turkey’s central mountainous region. In two small villages the mesothelioma lung cancer accounted for 43% of the deaths during 23 years period of study. Erionite fibers were found in biopsies of lungs of the mesothelioma cancer afflicted people. Comparing this to a 9.7% rate of death from this disease among asbestos insulation installers shows how anomalous this condition was.
Further studies showed erionite causes similar diseases in laboratory animals. When researchers at Mt. Sinai Hospital injected rats with the same dosage of erionite that they used for asbestos, the rats didn’t live long enough to get mesothelioma cancer. At a much-reduced dose, the rats did get cancer. Erionite is probably the most toxic known mineral - a milligram of fibers in the lungs is lethal.
Today erionite is considered so hazardous that the EPA requires any one who intends to manufacture, import or process any article containing erionite to notify the E.P.A. 90 days in advance. This gives the EPA a chance to review, limit or prohibit that activity. Read the rest of article here..

Erionite is no longer mined or marketed for commercial purposes. Although other natural zeolites have many commercial uses (pet litter, soil conditioners, animal feed, waste-water treatment, gas absorbents, etc.) So potential occupational exposure to erionite occurs during the production and mining of other zeolites.

And there are questions:

Are there other mineralogical hazards like erionite and asbestos?

Should we expected mesothelioma lung cancer increases not only from asbestos exposure after another 20 - 30 years?

Mesothelioma Cancer main factors

Mesothelioma cancer can strike anyone, but appears more often in men than in women. It is a disease mainly linked to asbestos and smoke, since most people who have worked on jobs where they breathed in asbestos particles, have developed this pathology.

Experts believe that smoking does not seem to be a directly related risk for developing the disease only by its own, but its combination with asbestos exposure increases the risk of Mesothelioma, so stop smoking if you are exposed to asbestos in your workplace.

According to statistics eight out of ten of all reported cases were exposed to asbestos, however there are cases of people that have not had any exposure to the fibers of this mineral.

Therefore, the main risk factor for developing Mesothelioma can be found in asbestos, a group of fibrous metamorphic minerals which have an special resistance to fire. Asbestos have been exploited for a variety of purposes, such as industrial products, roof shingles and flooring products.

However, some uses of asbestos are banned in many countries, since it is known that the inhalation of some kinds of asbestos fibers can cause various illnesses, including Mesothelioma, lung, larynx and kidney cancer and asbestosis, a chronic lung ailment, but a non cancerous pathology.

Most asbestos fibers are invisible to the unaided human eye and the problem increases because just one asbestos fiber can become the source of hundreds of thinner and smaller fibers over time. As they get smaller and lighter, they become more mobile and more easily to be driven and carried by the air.

That is why people who work in asbestos mines and mills or producing asbestos products must wear personal protective equipment to lower their risk of exposure, according to acceptable levels of asbestos exposure in the workplace set by the Occupational Safety and Health Administration of the United States.

In order to reduce your chance of getting ill with some of the asbestos-related diseases if you are a asbestos worker, is not only to wear the proper clothes and equipment, but also take a shower and change your clothing before leaving the workplace to diminish the possibility of dust brought home on your clothing or hair.

An Introduction to Mesothelioma

Malignant mesothelioma is a rare form of cancer that affects the mesothelial cells of the serous membranes in the body. The most common form of mesothelioma, affecting the lining of the lung, is pleural mesothelioma. Two to three thousand new cases of malignant mesothelioma are diagnosed each year.

The mission of All About Malignant Mesothelioma is to provide a one-stop resource for comprehensive, up-to-date mesothelioma information. We cover the full scope of malignant mesothelioma issues including background, history, risk factors, diagnosis, and treatment. Please recommend the site to someone who may benefit from mesothelioma information.
Introduction to Malignant Mesothelioma
Malignant mesothelioma affects the lining or membranes of certain large cavities in the body. These cavities, called the serous cavities, house certain major organs in the body including the heart, lungs, abdomen and others. The membranes that surround these cavities are called the serous membranes. They serve to protect these major organs from the friction and abrasion that occur as the organs move against each other during typical daily functioning, such as breathing and heart beating. The serous membranes derive from specialized cells called mesothelial cells. These cells form to create the mesothelium, which is the major tissue layer of the serous membranes. Cancer that occurs in the mesothelium tissue is called mesothelioma.

Malignant mesothelioma takes on three forms:
Peritoneal mesothelioma, in the peritoneum or membrane surrounding the abdomen. A rare form of peritoneal mesothelioma can also affect the male testicles, because the lining around the scrotum is an extension of the peritoneum.
Pericardial mesothelioma, in the perdicardium or lining surrounding the heart.
Pleural mesothelioma, which is the most common form of malignant mesothelioma and affects the lining of the lung cavity.
All mesotheliomas are now considered to be malignant, or cancerous. They start as a localized tumor and spread rapidly to include most of the surrounding tissues and organs. Originally, fibrous cists and other non-cancerous growths that appeared in the serous membranes were thought to be mesotheliomas and were termed “benign fibrous mesothelioma” and “multicystic mesothelioma.” These conditions are now known not to originate in the mesothelial cells, but other cells within the serous membranes. These conditions are typically localized, non-cancerous and do not spread rapidly.
Etiology of Malignant Mesothelioma
Most cases of malignant mesothelioma are associated with a previous exposure to fibrous minerals, of which asbestos is the most important. There is now indisputable evidence of the role of these fibers in the development of this disease. This has been demonstrated in animal experiments and many other experiments. Not everyone who is exposed to asbestos fibers has developed malignant mesothelioma, suggesting that other factors may also be involved.
Although malignant mesothelioma is rare, it is a serious, deadly disease. It is often in the advanced stages when it is detected, so the outlook for the patients is not as good as it is for the cancers that are detected earlier. The average survival time after detection is 1 to 2 years. This survival time also depends on the type of mesothelioma.

Mesothelioma asbestos and cancer

Many people have never heard of mesothelioma cancer, because it is rare. According to the National Cancer Institute, about 2000 new cases diagnosed in the United States each year. Compare that with 213380 cases of lung cancer predicts the Institute diagnosed in 2007.

Mesothelioma cancer begins in the fabric, mesothelieum, surrounds the lungs, stomach, heart and other organs. The mesothelieum protects these bodies with two levels and a liquid tissue, in the bodies to move. It is in the area around one of these organs, but it is often found in the chest and stomach.

Contact with asbestos is the major risk factor. Asbestos can be found in the insulation, in a number of buildings. Asbestos can also be found in the floor tiles, roof, dust and stones.

Most of the use of asbestos in the products for the construction was abandoned after 1989. But the cancer can be diagnosed, not before 20 to 50 years after exposure, because it’s much time to develop.

Therefore, the majority of cases occur in people in their late 50’s, and more. According to the American Cancer Society, the three-quarters of patients are diagnosed, are older than 65 years.

Among the other factors in the context of this situation are:

* Radiation. A document that thorium as carbon dioxide was used in the x-radiation is the cause of cancer. But, this material was not used for many years.
* Tobacco. Smoking is not directly related to this type of cancer, asbestos and smoking, but increases the risk of lung cancer, according to the American Cancer Society.
* Virus virus simien 40th This virus was found in the vaccines against polio in the mid-50’s and early years of the 60 years. Because the symptoms are not for the 20 to 50 years old, it might be some time before we know whether the virus is a risk factor.

The symptoms are different from person to person depending on where the affected tissue. All in all, the symptoms include:

* Shortness
* Pain in the chest
* Abdominal Pain
* Abdominal swelling
* Fever
* Anemia

The treatments are dependent on the patient. Many patients have surgery to remove the feed and tissue, which is affected. In severe cases, the tissue around the breast, lung or part of the diaphragm can be removed.

The doctors may recommend some patients, radiation therapy, in the high energy of radiation to kill tumors shrink and the affected cells.

Another treatment, chemotherapy, can be recommended, but it was not successful in the treatment of patients with mesothelioma. According to the American Cancer Society, the anti-angiogenesis drugs that kill these cells by their verdict supply of blood in the study.

The prognosis for patients is dark, because the disease is often from the date on which it is intended. According to the American Cancer Society, the five year survival rate is about 10 percent. Most patients survive a year after diagnosis. New therapies and clinical trials are under way to secure the survival rate of patients with cancer mesothelioma.
