Mesothelioma and Other Asbestos Related Cancers

People who have a long exposure to asbestos are at risk of developing various kinds of cancers, including mesothelioma. These cancers have a long time to develop, meaning that symptoms do not appear for decades after exposure.

The risk of developing pleural and peritoneal mesothelioma declines with time since first exposure. The evidence is built on six cohort studies of occupational exposure and two residential cohorts with long-term follow-up.

What is Mesothelioma?

Mesothelioma, also known as cancer of the internal organs' linings, like the lungs (pleural) or abdomen (peritoneal) and the heart (pericardial), is a rare and invasive disease. It's a rare, aggressive disease that usually begins in the lining of the chest cavity, but it could be found in the lining of the stomach or in other areas of the body. Asbestos is the most significant cause of mesothelioma. The cancer usually doesn't show up until decades after exposure.

Workers exposed to asbestos at work have higher chances of developing the disease than other. Asbestos fibers can be breathed in or swallowed and adhere to the organ's lining. They can cause irritation to the lining and cause abnormal cells to multiply and develop into tumors. The symptoms usually don't appear until the person has advanced mesothelioma.

Most asbestos lawyer exposure occurs in industrial jobs, where workers handle the material or work near it. Asbestos is used in many trades, such as construction, shipbuilding and auto repair. Veterans who served in military are at greater risk of developing mesothelioma due to asbestos because it was commonly employed on bases and ships.

Anyone with an asbestos-related history should be screened regularly and be aware of any unusual symptoms. If the doctor suspects mesothelioma, they may request imaging tests such as CT scans, MRI or PET scans to detect tumors and determine if they have developed. They can also conduct an examination and inquire about a patient's asbestos case exposure background. Certain mesothelioma cases are linked to genetic changes, and therefore some patients might benefit from genetic tests.

Risk Factors

The exposure to asbestos is the primary risk factor of mesothelioma. Asbestos is a substance made up of tiny fibers that are tough and withstand heat. Asbestos was employed in a variety of manufacturing and construction products such as insulation, brakes, shingles, flooring and more. Asbestos dust can be inhaled and swallowed when it is disturbed. This can cause irritation of the mesothelium over time, which could eventually lead to mesothelioma.

People who have a history of occupational asbestos exposure are at highest risk of developing mesothelioma. This includes those who been employed in industries such as mining, shipbuilding and construction, as well as automotive repair. Veterans of the military are also at risk, since many branches of service used asbestos-based material.

Other factors that increase the risk of mesothelioma are a family history of asbestos law exposure and previous radiation therapy to the chest. The type of mesothelioma that is diagnosed also has a major impact on the risk. The most frequent mesothelioma that is one that affects the lung. Other mesothelioma forms include the peritoneal (pericardial), testicular, and the peritoneal.

In general mesothelioma is a cancer that increases with the third or fourth power of latency, which is the time it takes for someone to get diagnosed. However, the rate of pleural mesothelioma exhibits a slight flattening approximately 40 years of exposure. Pericardial and peritoneal mesothelioma exhibit this trend too. Exposure to asbestos that is not occupational which includes living near an asbestos plant or eating food products contaminated by asbestos can increase the risk of mesothelioma. One study of six cities showed that those who had this type of exposure were at a higher mesothelioma risk than those who only had occupational exposure.

Signs and symptoms

Malignant mesothelioma can affect the tissue of the organs' linings. Most commonly, it occurs in the lung lining and abdomen. Mesothelioma can also develop in the lining around the heart or testicles. It is a rare cancer and the majority of people diagnosed with mesothelioma worked in jobs that required exposure to asbestos. The signs of mesothelioma may take years to appear, and the condition is not curable.

Asbestos is a group of minerals that have thin microscopically-sized fibers that are resistant to heat, fire, and chemicals. It was previously widely used in construction, shipbuilding, manufacturing and many other industries. Exposure to asbestos could cause mesothelioma as the fibers can get stuck in the tissues of the lining and protect organs. This causes irritation and damages cells. This can lead to tumors growing and eventually becoming cancerous.

The most prevalent mesothelioma type is found in the tissue (pleura) of the lung. It may also begin in the abdomen's lining (peritoneum) or in the membrane that surrounds the heart or testicles. Mesothelioma can also spread to the lymph nodes, causing them to expand.

Most people who are diagnosed with mesothelioma are those who have an extensive history of exposure to asbestos and are suffering from other diseases like chronic lung diseases. Mesothelioma symptoms are similar to other diseases, so you should consult a doctor if any persistent or worrying symptoms persist. Doctors will ask you about your asbestos exposure in the past and may also conduct physical examination. They can also order scans of your body or blood tests of your chest and abdomen. These tests will reveal any signs of thickening or fluid between the lungs and chest wall.

Diagnosis

When asbestos fibers are entangled to the body, they could cause damage and could eventually turn into cancerous tumors. Asbestos-related cancers can form in various organs or tissues. Each type of cancer is identified by a specific test. Mesothelioma can develop in the linings of the chest cavity, lungs and stomach (peritoneum), or around the heart or reproductive organs.

The first step in identifying mesothelioma is to talk with their doctor about their history with asbestos exposure and what symptoms they have been experiencing. Doctors can also conduct an examination of the body and order tests to determine the health of the lungs.

X-rays and CT scans allow doctors to get a better view of the affected area. In certain cases, doctors will use an pleural effusion test in order to determine if mesothelioma, or another disease is causing the accumulation of fluid in the lungs. The pleural effusion may be a symptom of mesothelioma of the pleura, peritoneal mes or a rarer type of mesothelioma known as biphasic or mixed mesothelioma.

The mesothelioma symptoms are frequently misdiagnosed, as they resemble the symptoms of other diseases. The most common symptoms include chest pain and breathing difficulties. Pleural mesothelioma can also cause chest tightness, cough and fatigue. Peritoneal mesothelioma can cause abdominal discomfort swelling and distension. Testicular mesothelioma may manifest as a swollen or itchy lump on the testicles.

Researchers are studying the presence of certain proteins in the blood to find an approach to detect mesothelioma earlier in its development. They are also investigating several other tests and procedures which can improve diagnostic accuracy. These include mesothelioma images and MRIs. They are also researching genetic mutations and how to determine if a person has a mesothelioma-related risk by studying their family history.

Treatment

Asbestos exposure is the main risk factor for mesothelioma. People who have worked with asbestos in the past, particularly for long periods of time or in high risk jobs such as shipbuilding, electrical work military and auto repair, are at increased risk.

Exposure to asbestos triggers mesothelioma, when fibers are trapped in tissue that lines and protects vital organs. The mesothelium is irritated by the asbestos fibers and cause DNA damage that can lead to cancerous cells. The symptoms of mesothelioma typically don't appear until decades after exposure.

The symptoms of mesothelioma differ depending on the type of cancer and its location in the body. Most mesothelioma cases involve the lung lining (pleural mesothelioma) however it may also occur in the stomach's lining (peritoneal mesothelioma), heart (pericardial mesothelioma) or testicles (testicular mesothelioma).

Mesothelioma staging helps doctors determine treatment options. The disease is categorized as stages I to IV with stage I and II being the earliest stages and most treatment-able. Stage III and stage IV are the last stages of cancer, and are more difficult to treat. However there are still many options for treatment.

Pleural mesothelioma is by far the most frequent form of the disease and affects the lung lining and chest wall as well as the abdomen. In most cases of pleural mesothelioma, asbestos exposure occurred in the workplace. It was most likely due to exposure to asbestos particles in the air or ingesting the cancerous substance through the food chain.

Other risk factors include a family history of mesothelioma, genetic mutations, and previous radiation therapy for another condition. If you were exposed to asbestos and have mesothelioma symptoms it is important to see an expert. Genetic counseling can also be beneficial. A mesothelioma specialist can assist you in filing a lawsuit against companies that have knowingly used asbestos legal (in the know) in their everyday products.
