Mesothelioma and Asbestos
Asbestos, a mineral that naturally occurs in the form of thin, long fibers. Workers who are regularly exposed to asbestos may develop lung diseases, such as mesothelioma.
It can take years before symptoms begin to manifest after exposure to asbestos. Different types of asbestos can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer of the lung's outer lining, or pleura. It is the most prevalent mesothelioma that accounts for up 70% to 79% of diagnosed cases. This condition causes chest pain, breath shortness and a feeling of heavyness.
Exposure to asbestos, a group of minerals made of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled, cause irritation and DNA mutations. The pleura surrounds the chest cavity and lungs This means that these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.
The most common symptoms of pleural melanoma are chest pain and shortness of breath. Patients may have coughing problems, trouble breathing, or chest tightness. Patients with this type of cancer have a history that includes asbestos exposure at work. The most frequent jobs that expose people to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. People who were in the military are at a greater risk due the extensive use asbestos in Navy vessels and Army bunkers.
The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used to treat pleural adenocarcinoma. The stage a patient has upon diagnosis will help their doctor determine the best treatment plan for them. For example, patients with a pleural mesothelioma in stage three or four have a worse prognosis than patients with lower stages. Stage four mesothelioma is often spread to the liver, diaphragm or even the heart of a patient. This could make the cancer more difficult to treat and increase the risk of complications for the patient.
Peritoneal Mesothelioma
Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum - it is a membrane that lines the abdominal cavity and organs like the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the cause of peritoneal mesothelioma. The disease is less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.
Like pleural mesothelioma, the symptoms may take years to appear. Typically, patients experience abdominal pain and an abdominal mass. The symptoms of this kind of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can lead to confusion in diagnosis.
Typically, doctors can identify mesothelioma after an extensive health history and physical examination. They can also utilize imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal cancerous tumors or other symptoms of cancer that aren't apparent on an X-ray.
These tests enable doctors to diagnose mesothelioma and determine the stage. They also offer treatments. The stage is determined by the type of cell as well as whether the tumor has spread.
The most important mesothelioma risk factor is exposure to asbestos. People who have worked in professions which require asbestos, like plumbing, manufacturing, electrical work, or construction, are at greater risk of developing the disease. However, even if people do not work in these fields, they can still be exposed to asbestos through family members or other sources. Anyone who believes they are at risk should speak with an expert. If they have a history of asbestos exposure or mesothelioma, a specialist can assist them in finding out more about their risk.
Risk Factors
Asbestos is the most significant mesothelioma-related risk factor. It is responsible for as much as 80percent of cases. Exposure to asbestos may occur through work, military service, or by living with someone who is exposed to asbestos or has previously done such. Asbestos particles are inhaled by those who are exposed to asbestos. The particles cause irritation to the linings of the lungs, causing cancerous cells to develop in the mesothelium. After exposure to asbestos mesothelioma is likely to develop between 15 and 60 years.
Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or more senior. This is because mesothelioma usually takes 20 to 60 years after the initial exposure before cancer symptoms appear. It is important to keep in mind, too, that mesothelioma may occur in those who have been exposed to asbestos without having been directly exposed to it. This is referred to as indirect or secondary asbestos exposure, and is as hazardous as direct asbestos exposure.
Smoking increases the chance of mesothelioma since it damages mesothelium. It also makes it more prone to. Mesothelioma can also be aggravated by certain illnesses such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos for a longer time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come into exposure to asbestos and don't typically carry asbestos around on their clothes.
Diagnosis
It is difficult to identify mesothelioma due to its symptoms being often similar to other conditions. plano asbestos law firm to this, patients are sometimes wrongly diagnosed.
NYU Langone doctors will perform an examination of the body and document the patient's medical background, including asbestos exposure. Doctors may also request a CT scan or chest X-ray in order to look for lumps, abnormalities and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.
Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI, test, which makes use of radio waves and magnets to make a series of detailed images of the inside of the body. Another way for doctors to detect mesothelioma is by performing an operation called a biopsy. In a surgical biopsy doctors take a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist then examines the tissue with an magnifying glass to determine if it is a cancerous cells.
Mesothelioma is classified according to the type of mesothelial cells involved, whether those cells are malignant or benign, and the location of the tumor, the type, and the stage of the tumor. Certain types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to have a clear diagnosis so doctors can treat the disease before it becomes out of control.
Doctors can also perform tests in the lab on tumors to identify specific proteins, genes, or other factors which will help them identify cancer characteristics and plan treatment. These results are called staging.
Treatment
A mesothelioma diagnosis is terrifying. However, it's important to keep in mind that the cancer is treatable, particularly in its early stages. Many mesothelioma patients live for a long time with the disease without it spreading to other parts of their body.
Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibres, too small to be felt or observed with the naked eyes are able to become airborne and irritate the lining of the lung (pleura). In time irritation can lead to formation of scar tissue, which can cause changes in the cell structure that eventually develop into tumors.
The pleura is the area that surrounds the lungs and heart and also the abdomen. Mesothelium is composed of cells that react to asbestos, causing it to inflame and create scar tissue. As time passes, these changes result in the growth of malignant mesothelioma tumors.
A shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all signs of pleural msothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.
A doctor will request a biopsy if imaging scans show a potential tumor in the lungs or stomach. During the procedure, doctors will remove small amounts of the tumor or fluid for lab testing. The results can confirm a mesothelioma diagnosis, and indicate the best treatment plan.
There are several types of mesothelioma treatment, including surgery, chemotherapy and immunotherapy. Most doctors use the combination of these treatments. Participating in clinical trials of mesothelioma treatments that are new could be beneficial for patients. Patients can find out more by consulting a mesothelioma specialist who has treated mesothelioma.
