Mesothelioma and Asbestos
Asbestos is a mineral that naturally forms in the form of long, thin fibers. Workers who are exposed
asbestos attorney on a regular basis are at risk of developing mesothelioma as well as other lung diseases of different types.
It may take decades before symptoms begin to manifest after exposure to asbestos. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer that develops in the outer lung the lining (pleura). It is the most frequent mesothelioma type and is responsible for 70 to 79% all diagnosed cases. This condition causes chest pain, shortness of breathe and a feeling of heavyness.
Exposure to asbestos, a group of minerals made of microscopic fibers, usually causes this type of cancer. Once inhaled, the fibers are absorbed into the lung and cause irritation which leads to scarring and DNA mutations. The pleura covers the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.
The most frequent symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Patients may also suffer from chest tightness and coughing, or breathing difficulties. People with this cancer have a past that includes asbestos exposure at work. The most prevalent jobs that put people at risk of pleural mesothelioma include manufacturing, construction and shipbuilding. People who were in the military are at a higher risk due to the frequent use of
asbestos settlement in Navy vessels and bunkers in the Army.
The most commonly used staging system for pleural mysothelioma has been the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at upon diagnosis will aid their doctor in determining the most effective treatment plan for them. For instance, patients suffering from mesothelioma pleural stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver and/or a person's heart. This makes it more difficult to treat and increases the risk of complications for patients.
Peritoneal Mesothelioma
Unlike pleural cancer, which forms in the lining of the lung it develops in the membrane that covers the abdominal cavity, which includes organs such as the liver and intestines. Similar to pleural mesothelioma mesothelioma can be caused by asbestos exposure. Only 300-500 cases are diagnosed annually this is less than the pleural asbestosis.
As with pleural asbestosis symptoms can take years to show. Patients generally have abdominal pain, and may also have a lump in their abdomen. This kind of mesothelioma can also cause nausea, weight loss, and fever. Many of these symptoms could be mistaken for gastrointestinal problems, leading to a misdiagnosis.
Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't visible on X-rays.
These test results enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.
Asbestos exposure is the main risk factor. People who have worked in jobs that involve asbestos, like plumbing, manufacturing, electrical work or construction, are at a higher risk of developing the disease. However, even if individuals do not work in these fields, they can still be exposed to asbestos through relatives or other sources. Anyone who believes they're at risk should talk to a doctor. A mesothelioma expert can help those who have a previous history of asbestos to find out more about their risk.
Risk Factors
Asbestos is the main risk factor in mesothelioma. It accounts for up to 80percent of cases. Exposure to asbestos can happen through work, military service, or by living with someone who works with asbestos or has previously done so. Asbestos particles are inhaled by those who are exposed to it. These particles irritate the linings, causing cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.
Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely to get mesothelioma than people younger or older. This is because mesothelioma typically lasts between 20 and 60 years from the initial exposure before symptoms of cancer begin to manifest. It is important to note that mesothelioma can develop in those who have been exposed to asbestos without having been directly exposed to it. This is known as secondary or indirect asbestos exposure, and is as dangerous as direct asbestos exposure.
Smoking increases the chance of mesothelioma since it damages mesothelium. It can also make it more vulnerable. Mesothelioma can also be caused by certain diseases, such as asbestosis and pneumonia. It is also important to note that mesothelioma is more prevalent in males than females. This is because men are more likely to work with asbestos and have more exposure than women. Men are also more likely to live with someone who had asbestos case (

asbestos claim fibers home on their clothing. Women are less likely to come into exposure to asbestos and don't typically carry asbestos around on their clothes.
Diagnosis
Mesothelioma is difficult to recognize because the symptoms often resemble other conditions. Due to this, patients are often wrongly diagnosed.
NYU Langone doctors will perform physical examinations and document the patient's medical background, including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray in order to look for lumps, abnormalities, and evidence of exposure to asbestos. These include plaques in the pleura, thickened pleura and calcium deposits.
Other diagnostic tests include a magnetic resonance scan, or MRI test, which makes use of radio waves and magnets in order to produce a series of precise images of inside the body. Another way for doctors to detect mesothelioma is to perform a surgical biopsy. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum for further testing. A pathologist can then examine the tissue under an magnifying glass to determine whether it contains cancerous cell.
The type of mesothelial cells involved and the benign or malignant nature of those cells as well as the location the cancer, its type and the stage of the tumour, are used to categorize the disease. Certain types of mesothelioma may be more likely to develop metastasis or spread which is why it is crucial to establish a definitive diagnosis so doctors can treat the disease before it goes out of control.
Doctors can also run laboratory tests on a tumor to find specific genes, proteins and other factors that help them understand the characteristics of the cancer and determine a treatment. These results are referred to as staging.
Treatment
A diagnosis of mesothelioma can be terrifying. It is important to keep in mind that cancer can be treated particularly in its initial stages. Many mesothelioma patients live for years without the disease spreading to other organs of their body.
Exposure to asbestos can cause mesothelioma by a variety of mechanisms. Asbestos fibers, too small to be able to see or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). Over time, the irritation leads to the formation of scar tissues that eventually result in tumors.
The pleura covers the lungs and heart, as well as the abdomen.
