Mesothelioma and Other Asbestos Related Cancers People with a long exposure to asbestos are at risk of developing various kinds of cancers, including mesothelioma. These diseases have a lengthy time to develop, meaning that symptoms do not manifest for years after exposure. The risk of developing pleural and mesothelioma of the peritoneal region decreases since the first exposure. The evidence is based on six occupational cohort studies and two residential cohorts with long-term following. What is Mesothelioma? Mesothelioma is a cancer of the inner organs' linings, including the lung (pleural mesothelioma) or abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It's a rare and aggressive disease that typically begins in the chest's lining cavity, but it may also be found in the stomach's lining or other parts of the body. Asbestos exposure is the main cause of mesothelioma and the cancer is usually not able to appear until decades after the initial exposure. Those who are exposed to asbestos at work have higher chance of developing cancer than others. Asbestos fibers can be swallowed or inhaled and adhere to the lining of the organ. They irritate the lining of the organs which causes abnormal cells to grow and forming tumors. The symptoms usually don't manifest until a person has advanced mesothelioma. The most frequent exposure to asbestos occurs in the workplace in which workers handle the substance or work around it. Asbestos was used in shipbuilding, construction, auto repair and other trades. Veterans who were in the military are particularly at risk of developing mesothelioma because asbestos was used extensively on ships and bases. People with a past history of asbestos exposure need to be checked regularly, and should be aware of any unusual symptoms. If a doctor suspects mesothelioma, they may request imaging scans, such as CT scans or MRI scans to detect tumors and determine if they've grown. They can also conduct a physical exam and ask about a patient's asbestos exposure background. Certain mesothelioma cases are linked to genetic changes, and therefore some patients may benefit from genetic testing. Risk Factors Exposure to asbestos is the primary mesothelioma-related risk factor. Asbestos is a substance made up of tiny fibers that are strong and withstand heat. Asbestos was utilized in a range of manufacturing and construction products such as insulation, brakes, shingles flooring, and more. Asbestos dust is inhaled and swallowed if disturbed. In time, this may lead to irritation of the mesothelium which may eventually develop into mesothelioma. People who have an history of occupational asbestos exposure are at the greatest risk for mesothelioma. This includes those who have been employed in industries such as construction, shipbuilding, mining and automobile repair. Veterans of the military are also at risk, since many branches of military employed asbestos-based materials. Other factors that increase the risk of mesothelioma is an asbestos-related family history exposure and prior radiation therapy to the chest. In addition the mesothelioma type that is diagnosed has an impact on the risk. The most common type of mesothelioma affects the lung. Other mesothelioma forms include testicular, pericardial and peritoneal. In general mesothelioma, the risk increases with the third or fourth power of latency, which is the length of time it takes for a patient to be diagnosed. However, the risk of pleural mesothelioma shows an apparent flattening after about 40 years after exposure. Peritoneal and pericardial mesothelioma both show this trend as well. Those who have para-occupational exposure to asbestos – such as living near to an asbestos plant or eating products that contain asbestos are also at a higher risk for mesothelioma. In a study of six cities, people who were exposed to asbestos in this way had a higher risk of mesothelioma compared to those who were exposed only to occupational exposure. Symptoms Malignant mesothelioma affects the cellular linings surrounding internal organs. It is most often found in the lining of the lungs (pleura) and abdomen (peritoneum). Mesothelioma can also form in the lining around the testicles or heart. It is a rare form of cancer, and the majority of people diagnosed with mesothelioma worked in jobs which exposed them to asbestos. It could take years for symptoms of mesothelioma to develop, and the disease is not curable. Asbestos is a group of minerals with tiny microscopically-sized fibers that resist heat, chemicals, and fire. It was widely employed in a variety of industries, such as shipbuilding, manufacturing, construction and many more. Exposure to asbestos may cause mesothelioma because the fibers get stuck in tissues that line and protect organs which causes irritation and damage to cells. This can lead to tumors expanding and eventually becoming cancerous. The most common type of mesothelioma is pleural mesothelioma, which develops in the lining of the lungs (pleura). It can also start in the lining of the abdomen (peritoneum) or within the membrane that surrounds the heart or testicles. Mesothelioma can also spread to the lymph nodes, causing them to expand. The majority of people diagnosed with mesothelioma are those who have a long history of exposure to asbestos, and are suffering from other diseases like chronic lung diseases. The symptoms of mesothelioma may be similar to those of other conditions and it is therefore important to visit a doctor if you observe any warning signs or symptoms. Doctors may ask about asbestos exposure in the past and conduct an examination. They may also order scans of your body or blood tests of your abdomen and chest. These tests will reveal any thickening or fluid between the lungs and chest wall. Diagnosis When asbestos fibers become stuck to the body, they could cause damage and may eventually turn into cancerous tumors. Different types of asbestos-related cancers form in various organs or tissues, and each type is diagnosed using a variety of tests. Mesothelioma develops in the lining of the chest cavity and lungs (pleura) and stomach membranes (peritoneum) or around the heart and reproductive organs. The first step in diagnosing mesothelioma is to talk with his or her doctor about their history of asbestos exposure and what symptoms they've experienced. Doctors also conduct a physical exam and order basic tests, such as blood work to determine how well the lungs function. X-rays or CT scans can aid doctors in identifying the affected area more clearly. In certain instances doctors will perform a pleural fluid test to determine if mesothelioma is responsible for the buildup of fluid. The pleural effusion may be a symptom of mesothelioma of the pleura, peritoneal mes or a less common form of mesothelioma called biphasic or mixed mesothelioma. Mesothelioma is often misdiagnosed because the symptoms resemble those of other diseases and conditions. The most common symptoms include chest pain and breathing difficulties. Pleural mesothelioma could also cause chest tightness, fatigue and a cough. Peritoneal mesothelioma can cause abdominal discomfort, swelling and distension. Testicular mesothelioma may manifest as a swollen lump that is itchy on the testicles. Researchers are studying the proteins in blood to create methods to detect mesothelioma early in its development. They are also researching a number of other tests and procedures that may enhance the accuracy of diagnostic tests, including mesothelioma imaging and MRIs. They are also looking into genetic mutations and how to determine if someone has a mesothelioma risk by looking at their family background. Treatment Asbestos is the most significant mesothelioma-related risk factor. Anyone who has worked with asbestos in the past, especially for long periods of time or in high-risk jobs such as construction, shipbuilding, electrical work, military and auto repair, are at increased risk. Exposure to asbestos triggers mesothelioma, when fibers are trapped in the tissue that lines and protects vital organs. The fibers cause DNA damage and irritation to the mesothelium, which can cause cancerous cells to grow. Symptoms of mesothelioma usually don't appear until decades after exposure. The symptoms of mesothelioma vary depending on the type of cancer and its location within the body. The majority of mesothelioma cases involve lining of the lungs (pleural mesothelioma), but it can be found in the lining of the stomach (peritoneal mesothelioma), heart (pericardial mesothelioma) or testicles (testicular mesothelioma). Mesothelioma staging helps doctors determine treatment options. The cancer is classified as stage I through stage IV with stages I and II being the earliest and most treatable. Stage III and stage IV are the later stages of cancer, and are more difficult to treat. However there are numerous options for treatment. The most prevalent mesothelioma type affects the lung linings, as well as the chest wall and the abdomen. In most cases of pleural mesothelioma asbestos exposure happened in the workplace. Most likely, asbestos was inhaled through airborne particles or inhaled through food items. Other risk factors are a family history, genetic mutations or prior radiation therapy for a different condition. If you've been exposed to asbestos and have mesothelioma symptoms it is crucial to see an expert. You may also benefit from genetic counseling. thornton asbestos law firm can assist you in filing a lawsuit against companies that have knowingly used asbestos in everyday products.
