Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that comes in thin, long fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases like mesothelioma.
Symptoms of these diseases may not show up for decades after exposure to asbestos. Different asbestos types can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a type of cancer that affects the outer lung lining (pleura). It is the most common mesothelioma form and accounts for 70% to 79% of all diagnosed cases. This condition causes chest pain, shortness of breathe and a feeling heaviness.
Exposure to asbestos, a group of minerals composed of microscopic fibers causes this kind of cancer. When inhaled, these fibers, cause irritation and DNA mutations. The pleura surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as a person's heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.
The most common symptoms of pleural melanoma are chest pain and breath shortness. Patients may also experience difficulty breathing or chest tightness. Patients with this type of cancer have a history of disease that includes asbestos exposure at work. The most frequent jobs that expose workers to the risk of developing pleural mesothelioma are construction, manufacturing and shipbuilding. Individuals who have been in the military are at a higher risk due to the frequent
asbestos law use in Navy ships and bunkers for the army.
The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that a patient is at upon diagnosis will help their doctor determine the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or stage four will have a less favorable prognosis compared to those in a lower stage. Stage four mesothelioma may spread to the heart, liver or diaphragm. This can make the cancer more difficult to treat, and increase the risk of complications for the patient.
Peritoneal Mesothelioma
Unlike pleural cancer, which is found in the lung's lining the peritoneal cancer is a result of a membrane that covers the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed each year which is lower than pleural asbestosis.
As with pleural asbestosis, symptoms can take a long time to manifest. The majority of patients experience abdominal pain and an abdominal mass. Symptoms of this type of mesothelioma can also include nausea or weight loss, as well as fever. Many of these symptoms are similar to those of gastrointestinal issues, which can result in confusion in diagnosis.
Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical examination. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer that are not evident on X-rays.
These test results enable doctors to identify mesothelioma, and determine the stage. They also offer treatment options. The stage of the disease is determined based on the type of cell and whether or whether the tumor has spread to other areas of the body.
The most important mesothelioma-related risk factor is exposure to asbestos. People who have worked in asbestos,

However, even if individuals aren't employed in these areas, they can still be exposed to asbestos through relatives or other sources. Therefore, anyone who is concerned that they might be at risk should speak to an experienced doctor. If they have a history of asbestos exposure and mesothelioma is a concern, a specialist will assist them in finding out more about the risk.
Risk Factors
Asbestos exposure is a major mesothelioma risk factor, accounting for up to 80 percent of cases. Exposure to
asbestos case can occur due to work, military service, or by living with a person who is exposed to asbestos or has previously done so. When exposed to asbestos, small particles are able to be inhaled into lungs and abdomen. These particles can cause irritation to the linings and trigger cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.
Other risk factors include genetics, smoking and aging. People in their 40s or 50s are at greater risk of developing mesothelioma compared to people who are younger or more. This is because mesothelioma usually occurs between 20 and 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to note that mesothelioma may occur in people who have been exposed to asbestos, but without having directly worked with it. This is known as secondary or indirect asbestos exposure. It can be just as harmful as direct asbestos exposure.
Smoking increases the risk of mesothelioma, since it damages mesothelium. It also makes it more prone to. Additionally, mesothelioma can be exacerbated by certain illnesses like asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with asbestos for longer periods of time. Also, men are more likely to live with someone who has was exposed to asbestos and bring stray asbestos fibers home on their clothes. Women tend to have less contact with asbestos and do not typically carry asbestos around on their clothing.
Diagnosis
Mesothelioma is difficult to diagnose because the symptoms often resemble other diseases. This could lead to patients being wrongly diagnosed.
NYU Langone doctors will perform physical examinations and document the patient's medical history including
asbestos case exposure. Doctors can also order a chest X-ray or CT scan to look for lumps and other abnormalities, as well as evidence of past asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as pleural effusion).
Other diagnostic tests include an echocardiogram which examines the heart and blood vessels as well as a magnetic resonance imaging, or MRI, test that uses magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. In a surgical biopsy doctors remove a small amount of tissue from the pleura or peritoneum to conduct further tests. A pathologist is then able to look at the tissue under a microscope to see if it is contaminated with cancerous cells.
The type of mesothelial cell involved as well as the benign or malignant nature of these cells as well as the location and stage of the tumour, are used to classify the disease. Certain types of mesothelioma are more likely to spread or metastasize and spread, therefore it is essential to establish a definitive diagnosis to ensure that doctors are able to treat the disease before it gets out of control.
Doctors may also conduct tests in the laboratory on tumors to determine specific proteins, genes or other elements that can help them describe cancer characteristics and plan treatment. These results are called staging.
Treatment
A diagnosis of mesothelioma may be frightening. However, it's important to remember that the disease is treatable, especially in its early stages. Many people with mesothelioma can endure the disease for a long time, without expanding.
