Mesothelioma and AsbestosAsbestos is a naturally occurring mineral that comes in thin, long fibres. Workers who are regularly exposed to asbestos risk developing lung diseases, such as mesothelioma.It could take a long time for symptoms to appear after exposure to asbestos. Different asbestos types can cause different symptoms.Pleural MesotheliomaPleural mesothelioma, a form of cancer, that develops in the lung's outer the lining (pleura). It is the most prevalent form of mesothelioma and accounts for 70% to 79% of diagnosed cases. This condition causes chest pain, breath shortness, and a feeling of heaviness.Exposure to asbestos, a family of minerals made of microscopic fibers, typically causes this kind of cancer. Once inhaled, the fibers stick inside the lungs and cause irritation that causes scarring and DNA mutations. The pleura surrounds the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.The most commonly reported symptoms of pleural mesothelioma include chest pain and breath shortness. Some patients may also suffer from chest tightness, coughing or difficulty breathing. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. Manufacturing, construction and shipbuilding are among the most common jobs which put people at risk danger of developing pleural melanoma. People who have served in the military could be at an especially high risk due to the widespread use of asbestos in Navy vessels and bunkers used by the army.The TNM (tumors, lymph nodes, and metastases staging system) is the most commonly used staging system for the pleural cancer. The stage that a patient is in at the moment of diagnosis will determine what treatment plan they should receive. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable outlook than those in a less advanced stage. Stage four mesothelioma may develop into the liver, heart, or diaphragm. This makes the cancer more difficult to treat and increase the risk of complications for the patient.Peritoneal MesotheliomaIn contrast to pleural cancer, that develops in the lung's lining it develops in a membrane that surrounds the abdominal cavity, including organs such as the intestines and liver. Similar to pleural mesothelioma mesothelioma can be caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.As with pleural asbestosis symptoms can take several years to show. Patients usually have abdominal pain, and could also experience a mass in their abdomen. Symptoms of this type of mesothelioma can also include nausea, weight loss and fever. Many of these symptoms could be misinterpreted as gastrointestinal issues and can lead to a mistaken diagnosis.Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. They can also use imaging tests like Xrays, CT scans and PET/CT scans to detect mesothelioma. These tests can show cancerous tumors or other symptoms of cancer that aren't apparent on an X-ray.These test results allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. The stage is determined by the type of cell as well as whether the tumor has spread.The most significant mesothelioma risk factor is asbestos exposure. People who have been in occupations that involve asbestos, like plumbing, manufacturing, electrical work, or construction, are at increased risk of developing the disease. However, even if people do not work in these areas they may be exposed to asbestos through family members or other sources. This is why anyone who believes they could be at risk should talk to a doctor. If they have any history of exposure to asbestos or mesothelioma, a specialist can help them find out more about their risk.Risk FactorsAsbestos exposure is a major risk factor for mesothelioma making up as much as 80 percent of all cases. Exposure to asbestos can occur due to work, military service, or by living with someone who works with asbestos or used to do such. When exposed to asbestos, small particles are able to be inhaled into lungs and abdomen. They can cause irritation to the linings of the abdomen and can cause cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.Other risk factors include smoking, genetics and age. People in their 40s and 50s are at a higher risk of developing mesothelioma compared to people who are younger or more. It is because mesothelioma generally takes 20 to 60 years from the initial time of exposure before cancer symptoms appear. It is important to note that mesothelioma can occur in people who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as indirect or secondary exposure to asbestos, and it is just as harmful as direct exposure.Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma is also aggravated by certain illnesses such as asbestosis and pneumonia. iowa asbestos attorney is also important to note that mesothelioma occurs more frequently for men than women. Men are more likely than women to have been exposed to asbestos for a longer time and to have worked with asbestos for longer periods of time. Men are also more likely to have lived with someone who had worked with asbestos and to have asbestos-containing fibers on their clothing. Women are less likely to come in contact with asbestos, and they are less likely to bring asbestos home on their clothes.DiagnosisIt is difficult to recognize mesothelioma because its symptoms are often similar to other conditions. Because of this, victims are sometimes wrongly diagnosed.The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take note of the medical history of the patient including asbestos exposure. Doctors can also request an X-ray chest or CT scan to look for lumps or other abnormalities, and also to look for evidence of past asbestos exposure like plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).Other diagnostic tests include a magnetic resonance image, or MRI test, that uses radio waves and magnets in order to create a series detailed images of inside the body. A surgical biopsy is yet another method for doctors to identify mesothelioma. In a surgical biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum to be examined further. A pathologist then examines the tissue using a magnifying glass to determine if it is a cancerous cell.Mesothelioma is classified according to the mesothelial type involved, whether these cells are malignant or benign and the location, type, and stage of the cancer. Certain types of mesothelioma may be more likely to grow or spread and spread, therefore it is essential to establish a definitive diagnosis so doctors can treat the disease before it gets out of control.Doctors can also run tests in the lab on a tumor to identify specific proteins, genes, or other factors that can help them describe the cancer's characteristics and plan treatment. These results are known as staging.TreatmentA mesothelioma diagnosis can be a frightening prospect. However, it's important to keep in mind that the cancer can be treated, particularly in its initial stages. A lot of people suffering from mesothelioma live with the disease for many years without it expanding.Exposure to asbestos can cause mesothelioma by a variety of mechanisms. Asbestos fibers, too small to see or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). In time the irritation causes the formation of scar tissues and eventually tumors.The pleura is the area that surrounds the heart and lungs and the abdomen. Mesothelium consists of cells that react to exposure to asbestos and cause it to enflame and create scar tissue. These changes eventually cause mesothelioma cancers.The symptoms of pleural mesothelioma are breathing problems and chest pain, or the accumulation of fluid in the lungs (pleural effusion). In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.If imaging scans reveal a possible mass in the lungs or stomach, a doctor will order a biopsies. In the course of the procedure, doctors remove small amounts of fluid or tumor to allow for laboratory testing. The results can confirm the diagnosis of mesothelioma and determine the best treatment plan.There are many types of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize an amalgamation of these techniques. Participating in clinical trials of new mesothelioma treatment may also be beneficial for patients. To learn more about the trials, patients should consult mesothelioma experts who have experience treating the condition.
