Mesothelioma~What Types of Injuries Are Caused By Asbestos?

When a person breathes asbestos, fibers can become lodged in the lungs. Once there, they can cause scarring. Asbestos fibers can also cause mesothelioma and lung cancer. The knowledge that asbestos can cause these fatal diseases has been known by many corporations since the 1920's.

The specific disease types associated with asbestos exposure include:

Mesothelioma
Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum. It is caused by asbestos exposure, it is not caused by smoking. It can occur 10 to 50 or more years after exposure.

Asbestosis
Asbestos can scar the lung and the lining of the lung. This scarring is known as asbestosis or interstitial fibrosis. If enough scarring occurs, it can impair the elasticity of the lungs and hamper their ability to exchange gases. As a result, there is inadequate oxygen intake to the blood. This impairment leads to shortness of breath. Over time, the breathing capacity can diminish and in some cases, become fatal.

Asbestosis, like other asbestos diseases, is a disease of latency -- it takes 10 to 40 years after exposure to asbestos for a person to become sick.

There is no known cure for asbestosis.

Lung Cancer
Asbestos also causes lung cancer. A person who does not smoke can get lung cancer from being to exposed to asbestos. If you smoked in the past or are presently smoking, and have been diagnosed with lung cancer, asbestos may also be a cause of your cancer. For smokers, asbestos and tobacco act together, greatly increasing the risk of lung cancer. The combination of smoking and asbestos can increase the risk of developing lung cancer.

Lung cancer, depending on its severity and the medical history of the individual, may be treated.

What is Asbestos?

Mesothelioma~What is Asbestos?

Asbestos is a naturally occurring rock form of magnesium silicate. It as mined by corporations fur use in a variety of products such as gaskets, rope packing, brake linings, pipe covering, joint compounds, cement, roofing materials and other insulation products. Click here for a list of asbestos containing products.

There are six types of asbestos - three of which have been used commercially. These are white (chrysotile), blue (crocidolite) and brown (amosite) asbestos. Over 90% of all asbestos ever used was the white asbestos.

During the installation, repair, maintenance, renovation and removal of asbestos materials, the products were cut, scraped, sanded and otherwise altered. Some materials, such as cements, were mixed at job sites using raw asbestos fibers. These processes created dust, which was breathed in by the laborers working with and around these materials. Dust from these products also traveled throughout buildings and factories and ships, and remained airborne for weeks. When swept, these materials were re-suspended in the air, where they were breathed in again by workers in the vicinity.

The dangers of asbestos were known to the companies that made these products as early as the 1920s. However, asbestos was sold and used without warnings up until the 1980s -- when most asbestos products were banned in the United States and other countries. Alternative materials were available that could have been used in place of asbestos.

A wide array of workers were exposed to asbestos including shipyard workers, factory workers, pipefitters, sheet metal workers, plumbers, laborers, machinists, mechanics, powerhouse workers, and electricians. One cloud of dust from asbestos products can contain millions or billions of fibers, and even a small amount of asbestos can cause lung damage. Mesothelioma has been diagnosed in family members of workers exposed to asbestos, learn more.

Often, individuals won't recall how they were exposed to asbestos, and may believe that they were not exposed to asbestos at all. A careful examination and review of a person's work and life history often reveals exposures to asbestos products that may not be readily apparent.

Mesothelioma Symptoms

The onset of mesothelioma symptoms is usually very slow, and may not appear until 30 to 50 years after exposure to asbestos. The following symptoms are frequently reported by those with mesothelioma, but are also associated with other medical conditions.

The following symptomatic responses MAY BE caused by mesothelioma. This information is provided for your information only, and should NOT take the place of a full medical diagnosis. If you are experiencing any of the below symptoms, consult your doctor right away.

Symptoms of Pleural Mesothelioma

* Pleural Effusions
One of the most common symptoms of mesothelioma is a pleural effusion, or an accumulation of fluid between the lining of the lung and the chest cavity. As the volume of fluid increases, shortness of breath, known as "dyspnea", and sometimes pain may occur.

* Shortness of Breath
Difficulty breathing (dyspnea) can be caused by a buildup of fluid in the pleural area of the lungs, and/or the presence of a tumor(s) in the pleural lining. Both conditions can restrict the proper functioning of the lungs, resulting in shortness of breath.

* Chest / Back Pain
A buildup of fluid in the pleural lining of the lungs can create a feeling of fullness and pressure, causing areas of localized pain in the chest cavity and sometimes in the lower back area. Chest pain occurs more often on the right side of the body, as mesothelioma affects the right lung 60% of the time. Only 5% of patients have mesothelioma in both lungs.

* Chronic Hoarseness / Difficulty Swallowing / Coughing up Blood
Chronic hoarseness, difficulty swallowing (dysphagia), and/or the coughing up of blood (hemoptysis) are symptoms that are exhibited in less than 1% of undiagnosed mesothelioma sufferers.

* Swelling of the Face and Arms
The swelling of the face or neck areas can indicate a spreading of the cancer beyond the mesothelium.

* Other reported symptoms include fever, muscle weakness and sensory loss, and nausea.

Symptoms of Peritoneal Mesothelioma

* Pain or Swelling of the Abdomen
Symptoms of peritoneal mesothelioma usually include abdominal pain and swelling due to a buildup of fluid in the abdomen (ascites).

* Bowel Obstruction
A tumor in the peritoneum membranes can exert increasing pressure on the organs in the abdomen, leading to bowel obstruction and distention.

* Weight Loss / Anemia
Abdominal pain, bowel obstruction, and the pressure exerted by the presence of a tumor(s) can lead to a loss of appetite, nausea, weight loss, anemia, and other 'wasting symptoms'.

* The presence of tumors in the peritoneal tissues of the abdomen can also cause a frequency in urination, night sweats, fever, and loss of muscle tissue.

Definition of Mesothelioma

Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and internal chest wall), but it may also occur in the peritoneum (the lining of the abdominal cavity), the heart, the pericardium (a sac that surrounds the heart) or tunica vaginalis.

A malignant tumor of the mesothelium. The mesothelium is the thin lining on the surface of the body cavities and the organs that are contained within them. Most mesotheliomas begin as one or more nodules that progressively grow to form a solid coating of tumor surrounding the lung, abdominal organs, or heart.

Mesothelioma most commonly occurs in the chest cavity and is associated with exposure to asbestos in up to 90% of cases. It has been shown that some asbestos fibers that are inhaled quickly work their way through the lung tissue and into the chest (pleural) cavity. Asbestos fibers that are swallowed have been shown to penetrate the wall of the intestine and appear in the abdominal (peritoneal) cavity.

The risk of mesothelioma increases with the intensity and duration of exposure to asbestos. It is debatable whether or not there is any safe exposure level. Mesothelioma typically does not occur for 20 to 50 years following exposure to asbestos. Some forms of asbestos, particularly crocidolite fibers, are more likely to cause mesotheliomas. There is also evidence that mesotheliomas may be caused by other agents including radiation, viruses, and man-made mineral fibers. There is no relationship to smoking.

Mesothelioma is currently difficult to treat in most cases and survival beyond two years is unusual.

Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or they have been exposed to asbestos dust and fiber in other ways. Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma. Unlike lung cancer, there is no association between mesothelioma and smoking. Compensation via asbestos funds or lawsuits is an important issue in mesothelioma (see asbestos and the law).

The symptoms of mesothelioma include shortness of breath due to pleural effusion (fluid between the lung and the chest wall) or chest wall pain, and general symptoms such as weight loss. The diagnosis may be suspected with chest X-ray and CT scan, and is confirmed with a biopsy (tissue sample) and microscopic examination. A thoracoscopy (inserting a tube with a camera into the chest) can be used to take biopsies. It allows the introduction of substances such as talc to obliterate the pleural space (called pleurodesis), which prevents more fluid from accumulating and pressing on the lung. Despite treatment with chemotherapy, radiation therapy or sometimes surgery, the disease carries a poor prognosis. Research about screening tests for the early detection of mesothelioma is ongoing.
