Mesothelioma Basics

0 comments
Mesothelioma is rare type of cancer that is caused by the exposure of asbestos. Asbestos is a naturally occurring mineral that has been and is still used in various building and construction applications due to its fire-resistant and insulating properties. 

Asbestos exposure is often caused by inhalation or digestion of microscopic fibers. When the microscopic asbestos brought into the body (most typically through inhalation), the particles attach themselves to the mesothelial lining of the lungs and can also attach themselves to the lining of the heart and abdomen. 

Many construction workers, shipyard workers, Naval vessel crew, asbestos manufacturing plant workers, power plant workers and chemical plant workers (to name just a few) are typically the ones who develop Mesothelioma due to their exposure to the toxic asbestos.

People can develop Mesothelioma at any age, however, many do not see aparent symptoms until their 70's and 80's. Common therapies for Mesothelioma include radiation therapy, surgery, anticancer drugs, and chemotherapy. Though the effects of asbestos exposure are quite apparent, the United States has yet to ban the manufacture of cancer causing agent.

Symptoms of Mesothelioma of the Heart

Of the 3,000 cases of mesothelioma each year, the rarest is mesothelioma of the heart called pericardial mesothelioma. The causes of pericardial mesothelioma is still not fully understood by scientists and doctors. Many scientists believe that asbestos is inhaled and ultimately makes its way to the blood stream however this is still very much a theory.


What is known is that asbestos fibers get stuck in the pericardial membranes of the heart. Over time, the accumalation of these asbestos fibers cause changes in the cells of the pericardium often resulting in cancer. Once these cells become cancerous, the divide and multiply rapidly. As these mesothelioma cells increase in quantity, the pericardial membranes thicken resulting in tumors. This build up puts pressure on the heart.

Since pericardial mesothelioma is so rare, it has been difficult for doctors to create a list of recognizable symptoms. The problem is that symptoms of pericardial mesothelioma resemble symptoms of other heart diseases. If any of the following symptoms are occuring, it is advised that one should seek medical attention as soon as possible. Only a number of specific tests can determine whether mesothelioma of the heart is apparent.
Symptoms of mesothelioma (pericardial mesothelioma) of the heart include:
  • Heart palpitations
  • Chest pain
  • Difficulty breathing (event at rest)
  • Fever
  • Night sweats
  • Fatigue

Symptoms of Mesothelioma of the Abdomen

There are 3,000 cases of mesothelioma a year and of those cases, 10 to 20% of those cases are mesothelioma of the abdomen called peritoneal mesothelioma. Peritoneal Mesothelioma occurs in the abdomen that effect the mesothelial cells that form the peritoneum. The peritoneum is comprised of two layers that surround, support and protect organs in the abdomen.

Like the other forms of mesothelioma, peritoneal mesothelioma is not complete understood as to how it forms. Many scientist believe that peritoneal mesothelioma is caused by one of two ways. The first theory is that asbestos is ingested and find there way to the digestive organs. The other way is by inhaling the asbestos fibers. The asbestos finds its way to the peritoneal membrane through the lymphatic system.

Regardless of how the asbestos fibers find their way to the abdomen, they can not be expelled. Over time, the peritoneum thickens often resulting in cancerous tumors. Like pericardial mesothelioma (mesothelioma of the heart) or pleural mesothelioma (mesothelioma of the lungs), peritoneal mesothelioma are vague and can often be confused with other non-serious diseases. However, if you or someone you know has been exposed to asbestos in the past 20 to 50 years (or ever), and you experience of the following symptoms, it is advised that you seek the consultation of a doctor. Only tests can determine if mesothelioma is present.

Symptoms of Mesothelioma of the abdomen area include:
  • Night sweats
  • Fever
  • Weight loss that can't be explained
  • Unexplained diarrhea or constipation
  • Nausea and/or vomiting
  • Lumps under the skin on the abdomen
  • Swelling and/or pain in the abdomen
  • Anemia
  • Fatigue

Symptoms of Mesothelioma of the Lungs

Mesothelioma of the lungs is called pleural mesothelioma. Symptoms of mesothelioma may not appear for 20 to 40 years after exposure and sometimes longer. Around 3000 people are diagnosed with malignant mesothelioma each year. Roughly 2/3 of mesothelioma cases are Pleural mesothelioma. Pleural mesothelioma occurs in the lining of the lungs called the pleural membrane.


Pleural mesothelioma is caused by the inhalation of asbestos fibers. Once the asbestos fibers are brought into the lungs, they find their way to the pleural membrane. Over time, typically 20 years and more, the accumulation of these fibers begins to scare the lining of the lungs. The scaring causes tumor growth on the lungs and ultimately cancer. The cancerous cells prevent the creation of healthy cells and ultimately the pleural member thickens. As a result, lung capacity is reduced and fluid begins to fill between the pleural layers.

Symptoms of mesothelioma of the lungs (Pleural Mesothelioma) include:
  • Dry or raspy cough
  • Night sweats
  • Fever
  • Unexplained weight loss (10% or more)
  • Difficulty in swallowing
  • Fatigue
  • Persistent pain in the chest
  • Painful breathing
  • Coughing up blood
  • Wheezing
  • Shortness of breath (even during rest)
  • Lumps under the skin on the chest

Mesothelioma Diagnosis

0 comments
Unfortunately, mesothelioma is a very difficult to diagnose as it is often detected well into advance stages of the disease. Often 20 to 50 years will go by from the initial asbestos exposure until characteristics of mesothelioma are evident. Typically, patients are often diagnosed with mesothelioma 3 to 6 months of first signs of the diseases which is most often abdomenal and chest pain and breathing problems.

Patients that are suspected to mesothelioma are given a number of tests to determine whether or not the disease is present. These tests include chest X-rays, CT scan, PET scan, and/or and MRI scan. These tests will determine if and where mesothelioma is present and at what stage.

Doctors will also do tissue and fluid tests (also known as biopsy tests) to determine if cancer cells are present. These tests involve small samples of body tissue and fluids. Such tests may include:
  • Thoracoscopy test- a test that is used when pleural or pericardial mesothelioma is suspected. This test involves producing a small tissue through the chest wall via a small incision.
  • Fine Needle Aspiration test - a long, hollow needle is used to extract fluid samples from such places as the pleural membrane of the lungs.
  • Bronchoscopy and Laparoscopy test - similar to the thoracoscopy test but done in other areas of the body.
  • Mediastinoscopy test - used to to view the lymph nodes in the chest and to see the stage of cancer and whether it has spread
