Mesothelioma and Asbestos Exposure

Malignant mesothelioma is a type of cancer that affects the lining of organs within. Asbestos exposure is the main risk factor.

Asbestos is a heat and fire-resistant mineral fiber used in a variety of occupations until it was banned in the 1970s. Miner, construction workers shipyard workers, factory workers, and veteran employees are at the greatest risk of exposure.

What is Mesothelioma?

The mesothelium acts as a protective lining that covers the various organs in the body. Malignant mesothelioma is most commonly located in the lungs and abdomen. It can also develop in the lining of the heart (pericardium) or in the testes. Each year, mesothelioma gets diagnosed in a few thousand Americans. The only cause that is known for this rare cancer is exposure to asbestos. Asbestos was once a popular fibrous material in American industries due to its low price and fire resistance. It was used to construct homes, buildings and automobiles. Workers who handled, removed or cut the material may have been exposed. Exposure to asbestos could cause mesothelioma to develop for decades after exposure.

The initial signs of mesothelioma typically resemble those of other diseases like lung cancer, making it difficult to determine. These early symptoms can include breathing problems, chest pain and a persistent cough. As the disease progresses more serious symptoms, including fatigue and weight loss, could develop.

There are four types of mesothelioma, and each type has a different prognosis. The most prevalent type is pleural. It affects linings of the lungs (pleura) and the chest cavity. Other mesothelioma types include peritoneal (pericardial) testicular and the peritoneal. Each type has its own distinctive symptoms, but all types are defined by an inflamed, malignant tumor that surrounds vital organs and disrupts their function.

If a doctor suspects mesothelioma, they will request a biopsy to look for cancerous cells. A tissue sample is taken from the affected area and examined under a microscope. If cancer is discovered the patient is diagnosed with epithelioid mesothelioma or sarcomatoid. Epithelioid mesothelioma accounts for 70% to 80percent of mesothelioma cases, and is more responsive to treatment. Sarcomatoid mesothelioma, on the other hand, accounts for less than 10% of mesothelioma diagnoses and has a lower prognosis than epithelioid mesothelioma.

Anyone who has been in contact with asbestos is at risk of developing mesothelioma. Certain groups are at greater risk of developing mesothelioma more than others. These include those who work in the asbestos industry, veterans of the military and those who have mesothelioma in their family. People who have had radiation treatments related to asbestos are also at risk of developing mesothelioma.

Mesothelioma Signs and Symptoms

Mesothelioma develops in the tissue that line and protect internal organs including the lung (pleura) and abdomen (peritoneum). The exposure to asbestos in the workplace increases the chance of developing mesothelioma. Pleural mesothelioma is by far the most frequent mesothelioma type. It affects the lining in the lungs.

Asbestos fibers can cause irritation to the mesothelium, and over time, the cells become damaged. The genetic changes that happen cause the cells to become malignant and form tumors. Symptoms of mesothelioma vary and can include coughing chest pain, and difficulty breathing. Other symptoms include nausea and fatigue. Weight loss is another symptom. Mesothelioma is a rare type of cancer it can take anywhere between 10 to 60 years to show its first symptoms. The symptoms are often mistaken for other illnesses like pneumonia or the flu. Mesothelioma can be difficult to recognize because it is rare, and its symptoms are similar to other diseases.

Doctors typically do not connect mesothelioma and asbestos exposure until the mesothelioma is at a late stage. The doctor will inquire about the patient's previous asbestos exposure and perform a physical exam. Imaging scans are used by doctors to help diagnose mesothelioma and rule out other diseases.

The physician may also recommend scans for blood and imaging for the chest or abdomen. The imaging tests can include CT scans, MRI, PET scans, or X-rays. A biopsy can be requested by the doctor to confirm the diagnosis of mesothelioma and to determine what kind of mesothelioma is present. The biopsy may be an exploratory procedure or a minimally-invasive procedure.

During the procedure, doctors take out small amounts of mesothelium and search for mesothelioma. The majority of mesothelioma diagnoses are epithelioid cells. The sarcomatoid type is less responsive to treatment and has shorter life expectancy. The epithelioid type is more responsive to treatment and has a better chance of survival. The biphasic form is a mixture of the first two types and accounts for 30 to 40% of all mesothelioma diagnosis.

Causes of Mesothelioma

Mesothelioma typically occurs in the lung linings and the abdomen. It can also be found in the linings of the heart or the pericardium. About 3000 people are diagnosed with mesothelioma each year. It is the only known cancer caused by asbestos. It takes between 20 and 50 years for mesothelioma growth after exposure.

Asbestos is a mineral that occurs naturally that is heat-resistant, has properties. For many years, it was used in many American industries because it was cheap and fire-resistant. The asbestos industry was particularly lucrative for the construction industry, as it was employed to insulate and strengthen vehicles, ships, buildings and other items. People who worked in the construction industry were most at risk for exposure to asbestos.

Workers who handled or removed asbestos were exposed to sharp fibers that could cause serious health problems. These fibers can be easily inhaled or swallowed and can irritate the mesothelium. As time passes the irritation causes scar tissue, which could result in tumors.

Different mesothelioma types affect different areas of the body. Pleural mesothelioma has the highest prevalence that affects the lining of the chest cavity and the lungs. It is the most prevalent type of mesothelioma and can cause symptoms like breathing problems or pain. Mesothelioma may also affect the lining of the abdominal cavity, causing symptoms like pain, swelling, or digestive problems. It can also affect linings of the heart, causing distinctive symptoms like chest pain or palpitations.

Mesothelioma symptoms can be mistaken with other illnesses. It is important to see your doctor if any of these symptoms are present. Your doctor will do an examination of your body and may request imaging scans to check for any abnormalities. These tests include CT scans MRIs and PET scanners. These tests can help doctors see if any mesothelioma-related changes are present within your body.

Mesothelioma may not be contagious however, family members of asbestos-related patients have a higher chance of developing the disease. This is because those who were exposed to asbestos often brought home asbestos fibers on their clothing hair, skin and even their hair. These individuals could inhale asbestos fibers. Secondary asbestos case exposure is the term used to describe this type of secondhand asbestos exposure.

Treatment for Mesothelioma

Mesothelioma, like other cancers is a result of cells in the human body begin to grow in uncontrolled ways. They also reproduce and spread to other parts of the body, leading to tumors (masses) to form.

The primary risk factor for mesothelioma is exposure asbestos case. Asbestos was a fibrous mineral used in construction, among other industries, before it was banned in the 1970s. When exposed, the tiny fibres can be inhaled and ingested. They can then be encased within the linings of certain organs, causing mesothelioma.

Mesothelioma is most common in people who have worked with asbestos legal. This includes those who are responsible for removing or handling it. However blue-collar workers and family members of asbestos-related workers are also at risk. Workers may bring asbestos law fibers back home on their clothing. Family members may inhale asbestos fibers when they clean their clothes.

Although mesothelioma can be found in a small percentage of cases, it is important to see a physician for any symptoms that may be related to the disease. These include chest pain, breathing difficulties or a persistent cough. The doctor will inquire about your medical history, and ask if you've ever been exposed to asbestos. The doctor may also perform an X-ray of the chest and a physical exam to look for mesothelioma. Other tests include a computed-tomography scan (CT), positron-emission tomography, or magnetic resonance imaging.

If mesothelioma is diagnosed, your doctor will talk with you about treatment options. This could include chemo, surgery or radiation. The type of mesothelioma and how it has advanced will determine what treatments are available.
