Mesothelioma and Other Asbestos Related Cancers People who have a history of asbestos exposure are at risk of developing several types of cancers, including mesothelioma. These cancers have a time-of-resistance of many years, meaning that symptoms may not appear until decades after exposure. The risk of developing pleural and mesothelioma peritoneal diminishes with time since first exposure. Evidence is based upon two residential and six occupational cohort studies with long-term follow-up. What is Mesothelioma? Mesothelioma is cancer of the inner organs' linings which include the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It's a rare and aggressive disease that usually begins in the chest's lining cavity, but it may also occur in the lining of the stomach or in other parts of the body. Asbestos exposure is the most common cause of mesothelioma, and the cancer usually doesn't develop until a long time after the initial exposure. Workers exposed to asbestos while at work are at higher chances of getting the disease than others. Asbestos fibers can be inhaled or swallowed and adhere to the organ's lining. They irritate the lining of the organs and cause abnormal cells to grow and form tumors. The symptoms typically don't show until a person is diagnosed with advanced mesothelioma. Exposure to asbestos most often occurs in jobs in the industrial sector where workers handled the material or were in close proximity to it. Asbestos was employed in shipbuilding, construction, auto repair and other trades. Veterans who served in the military are at particular risk of developing mesothelioma because asbestos was widely used on bases and ships. People with an history of exposure to asbestos should have regular checkups and be aware of any unusual symptoms. If a doctor suspects mesothelioma, they may request imaging scans like CT scans or MRI scans to look for tumors and determine if they've spread. They can also conduct a physical exam and ask about a patient's exposure to asbestos background. Some cases of mesothelioma can be caused by genetic changes. Therefore, some patients may benefit from genetic testing. Risk Factors Exposure to asbestos is the main risk factor of mesothelioma. Asbestos is a substance made up of tiny fibers that are durable and resistant to heat. Asbestos was once used in a wide variety of manufacturing and construction products including insulation, brakes, shingles flooring, and more. Asbestos dust can be breathed in and swallowed when disturbed. Over time, this can cause irritation of the mesothelium which can ultimately develop into mesothelioma. Mesothelioma is most common in those with had a history of occupational exposure to asbestos. This includes people who have been employed in industries such as mining, shipbuilding and construction, as well as auto repair. Veterans of the military are also at risk, since many branches of service used asbestos-based material. A family history of asbestos and radiation therapy for chest cancer are additional factors that increase the risk of mesothelioma. Furthermore, the mesothelioma type that is diagnosed has an impact on the risk. The most common mesothelioma type affects the lung. Other mesothelioma types include peritoneal, pericardial and testicular. In general mesothelioma, the risk increases with the third to fourth power of latency – which is the time it takes for a patient to get diagnosed. However, the incidence of pleural mesothelioma has a slight flattening around 40 years after exposure. Peritoneal and pericardial mesothelioma show the same trend. People who have a para-occupational exposure to asbestos – such as living close to an asbestos plant or consuming products that contain asbestos are also at a higher risk for mesothelioma. A study of six cities revealed that those with this kind of exposure had a greater mesothelioma rate than those who only had occupational exposure. Signs and symptoms Malignant mesothelioma can affect the tissue of the organs' linings. It is most often seen in the lining of the lungs (pleura) and abdomen (peritoneum). Mesothelioma can also develop in the lining of the testicles or the heart. It is a rare cancer and most people diagnosed with mesothelioma worked in positions that exposed them to asbestos. It can take decades for mesothelioma-related symptoms to manifest and the disease is not curable. Asbestos is one of the minerals with thin microscopically-sized fibers that are resistant to fire, chemicals and heat. It was widely used in many industries, including shipbuilding manufacturing, construction and many more. Exposure to asbestos may cause mesothelioma because asbestos fibers can become stuck in the tissues that line and protect organs. This causes irritation and damages cells. This can cause tumors to expand and eventually develop into cancerous. The most common form of mesothelioma occurs in the wall (pleura) of the lungs. It can also develop in the lining of the heart or testicles, or the abdominal lining (peritoneum). Mesothelioma can also spread to lymph nodes, which causes swelling of the lymph nodes. Most people diagnosed with mesothelioma are victims of exposure to asbestos and are also suffering from other ailments like chronic pulmonary disease. Mesothelioma symptoms can be similar to the symptoms of other diseases, and you should consult a doctor in the event that any worrying or persistent symptoms persist. Doctors will ask about your past asbestos exposure and may conduct a physical examination. They may also request imaging scans or blood tests of your chest and abdomen. These tests can detect any fluid or thickening between the lungs and chest wall. Diagnosis Asbestos fibers that are entangled on the body can cause damage and may eventually grow into cancerous tumours. Different types of asbestos-related cancers develop in various organs or tissues, and each type can be identified using different tests. Mesothelioma forms in the lining of the chest cavity and the lungs (pleura) and stomach membranes (peritoneum) or around the heart and reproductive organs. The first step to diagnose mesothelioma is to talk with their doctor about their history of asbestos exposure and the 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 or CT scans can help doctors see the affected area better. In certain instances, doctors use a Pleural Fluid Test to determine whether mesothelioma is causing the fluid buildup. The pleural effusion may be a symptom of mesothelioma of the pleura, peritoneal mes or a less common form of mesothelioma known as biphasic or mixed mesothelioma. The mesothelioma symptoms are often not properly diagnosed, because they are similar to the symptoms of other diseases. The most commonly reported symptoms are difficulty breathing and chest pain. Pleural mesothelioma can also cause fatigue, chest tightness and a cough. Peritoneal mesothelioma can cause abdominal discomfort swelling, distension and pain. santa fe asbestos lawyer may manifest as a swollen or itchy lump on the testicles. Researchers are studying the proteins in the blood to develop ways to identify mesothelioma at an early stage. They are also researching various other tests and procedures which could improve the accuracy of diagnosis. This includes mesothelioma scans and MRIs. They are also studying genetic mutations and ways to determine if a person is at risk of developing mesothelioma by looking at their family history. Treatment Asbestos is the primary risk factor for mesothelioma. People who have worked with asbestos, particularly in high-risk occupations such as construction, electrical work or auto repair, shipbuilding and military service, are at risk. Exposure to asbestos may cause mesothelioma when the fibers get stuck in the tissue that lines vital organs and protects them. The fibers cause DNA damage and irritation to the mesothelium, which causes cancerous cells to grow. The signs of mesothelioma generally don't appear until decades after exposure. The symptoms differ based on the type of mesothelioma and the location it occurs within the body. The majority of mesothelioma cases involve lung lining (pleural mesothelioma), but it can also occur 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 to stage IV, with stages I and II being the earliest and the most manageable. Stage III and IV are the more advanced stages of cancer that are more difficult to treat, however there are still a variety of treatment options available. The most frequent mesothelioma form affects the lung linings and chest wall and the abdomen. In most cases of pleural mesothelioma asbestos exposure was a result of the workplace. This is most likely because of breathing in asbestos particles from the air or ingesting the cancerous substance through the food chain. Other risk factors are a genetic mutation in the family or previous radiation therapy for a different ailment. It is important to consult an expert if you experience symptoms of mesothelioma or were exposed to asbestos. You may also benefit from genetic counseling. In some cases, a mesothelioma specialist can assist you in filing an action against companies that have knowingly used asbestos in their everyday products.
