:: Causes Of Mesothelioma ::

Mesothelioma is the growth of malignant cells in mesothelium, the thin membrane covering the body’s internal organs. This mesothelium lining covers the pleural, peritoneal and pericardial cavities. Pleura is a membrane covering the lungs and it is the most common location where mesothelioma cancer occurs also known as pleural mesothelioma. Peritoneum, the protective covering that lines the abdominal cavity may also develop malignant tumors and cause peritoneal mesothelioma.

Mesothelioma is one of the rarest cancers in the world that is caused only by exposure to asbestos. Its exposure can be direct, by inhalation of asbestos or indirect exposure in which the asbestos particles are inhaled from the clothing, hair, equipment or other articles that were previously exposed to asbestos

Causes of Mesothelioma
Asbestos is a naturally occurring fibrous mineral that is mined in different parts of the world due to its wide utility in various industries. However, it is a deadly carcinogen too and a mojor cause of mesothelioma and asbestosis.

Asbestos fibers are known to cause cancer of the mesothelium. Asbestos is the fibrous form of several minerals and hydrous silicates of magnesium found under ground. There are 3 types of asbestos, the blue one, the while one and the brown one. Of all these 3 types, the blue one also called amphibole, long and thin in structure is more carcinogenic than white or chrysolite asbestos or the brown one known as amosite.

However, in some cases the brown asbestos has also been found to cause mesothelioma. And it is for this reason that people exposed to asbestos even for a short period are vulnerable to the disease.

Pleural Mesothelioma
Asbestos fibers are very fine and easily make their way to the lungs where they settle down in the parenchyma of the lung and penetrate the pleura that later develops malignant mesothelial plaques.

Pleura, which anchors lungs to the chest cavity, is itself a double-layered membrane. The inner layer called visceral pleura surrounds the lungs, while the outer one, known as parietal pleura, forms the lining of the pleural or chest cavity. The two pleural layers are filled with a fluid that helps them to slide over each other as we breathe. As the disease progresses, the delicate pleural membranes thicken and press the lungs. A fluid secreted by the malignant cells, pleural effusion, may also collect between visceral and parietal pleurae that causes problem in breathing and other complications.

Peritoneum Mesothelioma
The asbestos fibers may also cause cancer in the peritoneum, known as peritoneal mesothelioma. This leads to thickening of the membranes surrounding abdominal organs and collection of a fluid, ascites in the abdominal cavity making it swell.

Though it is yet not clear how peritoneal mesothelioma develops, it is believed that from lungs, the asbestos fibers are transported to abdomen and its organs by the lymphatic system or they may be deposited in the gut through saliva contaminated by the asbestos fibers.

Pericardial Mesothelioma
This is the rarest type of mesothelioma cancer that comprises of only 5% of all the mesothelioma cases. Like other types of mesothelioma cancer, pericardial mesothelioma is also caused by the inhalation of asbestos dust and fibers. The lining of the chest cavity which protects the heart is known as pericardium. It is provided with a natural fluid or mucous that provide continuous lubrication to the heart so that it can work properly and perform its functions.

It is a very deadly disease that destroys the tissues around the heart and diminishes the survival chances of the patient. As the asbestos particles settle further into the lining of the chest or pericardial, the cancer spreads in the body. It destroys the heart tissues and muscles that is very hazardous to life and proves fatal for the patient.

:: Treating Mesothelioma ::

Mesothelioma is a cancerous disease that affects the serous linings of various internal organs in the human body. Among them, the lungs, heart and the stomach are widely affected.

It is estimated that each year 2,000 new cases of mesothelioma are diagnosed. The patients suffering from this cancerous disease have prior exposure to asbestos, which is considered to be the only known cause of mesothelioma. Mesotheliomic patients are often told of their short survival duration of 6 – 12 months, but doctors specialized in treating malignant mesothelioma at leading cancer centers expect more. Though mesothelioma causes immense pain and suffering to the victim, along with short life expectancy, certain treatments have resulted in the successful reduction and removal of the cancerous tumors of mesothelioma.

In this article, we will elaborate on the significant treatments available to patients suffering from the asbestos- related cancer (mesothelioma). Please be advised that only a professional doctor specializing in cancer can diagnose mesothelioma. It is recommended for patients suffering from the symptoms of mesothelioma, to consult a cancer specialist for a possible treatment. After examining medical reports and asbestos-exposure history, the doctor can announce the preliminary diagnosis. The doctor can also conduct a needle biopsy to finalize the diagnosis of malignant mesothelioma. For more relevant and latest Mesothelioma Information and diagnosing mesothelioma, check out www.mesoblog.org. Additionally, it is noteworthy that the treatment of mesothelioma depends on many factors, including the stage of the cancer, the circulation of the malignant cells, pathology reports determining the nature of the cancer cells and patient’s age and health.


Following are the mesothelioma treatment options available to the patients for treating the cancer:

•Surgery
•Chemotherapy
•Radiation or Radiotherapy
•Immunotherapy
•Clinical Trails
•Complementary Therapy
*Nutrition
*Fitness and Exercise
*Meditation and Stress Reduction

Treating mesothelioma is not an easy task. It requires immense pain endurance and patience. Nonetheless, with proper treatment and medications, along with the love and support from the family members and friends, mesothelioma can be controlled.

:: Symptoms of Mesothelioma ::

In most cases, people usually ignore the symptoms of Mesothelioma due to their generic nature. This is because the early symptoms of mesothelioma can also be the indication of other common diseases. Furthermore, researches have concluded that a patient with prior exposure to asbestos may develop mesothelioma much later in his/her life, i.e. after 20 to 40 years of asbestos encounter. Thus, many patients disregard the possibility of developing mesothelioma due to something that happened much earlier in their lives.

Mesothelioma is a cancer in which the protective linings of the body’s internal organs get affected by malignant cells. These linings include:

•Pleura: the outer lining surrounding the lungs and chest cavity;
•Peritoneum: the lining of the abdominal cavity; and
•Pericardium: a sac holding the heart.

The symptoms of mesothelioma affecting these organs can vary due to the special nature and functions of the organs. Some of these symptoms are severe, and also some of the symptoms are rare. It is, therefore, recommended to contact a physician if the symptoms prevail.
Additionally, if mesothelioma is detected at early stages, the chances for a possible cure are high.

Following are the symptoms of mesothelioma, categorized by types:

Pleural Mesothelioma Symptoms:

•Shortness of breath
•Coughing up blood
•Pain in chest
•Pleural effusions (fluid accumulation in the lung lining)
•Back pain
•Hoarseness
•Weakness
•Problem in swallowing
•Loss of appetite
•Weight loss
•Excessive coughing
•Swelling
•Paralysis
•Fever

In severe cases, a pleural mesothelioma patient can develop pneumothorax or lung cancer (lung failure). Nonetheless, some patients may show almost no symptoms.

Peritoneal Mesothelioma Symptoms:

•Swelling or mass accumulation in the abdomen
•Weight Loss
•Abdominal pain
•Bowel obstruction
•Blood clots
•Fever
•Nausea
•Vomiting
•Hernia

Pericardium Mesothelioma Symptoms:

•Chest pain
•Shortness of breath
•Cough
•Unusual heart beating
•Irregular breathing patterns

These symptoms of mesothelioma can also be the indications of other minor diseases. However, if diagnosed soon, these symptoms can help the doctors to cure the cancer at a primitive stage. Remember that only a doctor can confirm the presence of mesothelioma by examining medical reports, asbestos exposure history, MRI and/or CT scan. In some cases, a needle biopsy can also be conducted.
