Mesothelioma and Asbestos

Asbestos, a mineral that naturally occurs in the form of long, thin fibers. People who are exposed to asbestos may develop lung diseases like mesothelioma.

It can take years for symptoms to appear after asbestos exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that occurs in the lung's outer lining (pleura). It is the most frequent mesothelioma that accounts for up 70% to 79% of diagnosed cases. The condition can cause chest pain, breath shortness, and a feeling of weightiness.

Exposure to asbestos, a group of minerals composed of microscopic fibers causes this kind of cancer. These fibers, when inhaled can cause irritation and DNA mutations. The pleura covers the lungs and chest cavity, so these irritations can affect both the lungs and the heart of a person. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and breath shortness. Some patients may also feel tightness in their chest and coughing, or breathing difficulties. People with this cancer have a history of disease that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are the most frequent occupations which put people at risk chance of developing pleural mesothelioma. Individuals who have been in the military could be at a higher risk due to the frequent use of asbestos in Navy ships and army bunkers.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient has at diagnosis will assist their doctor in determining the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a less favorable outlook than those who are in a lower stage. Stage four mesothelioma can develop into the heart, liver or diaphragm. This makes the cancer more difficult to treat and increase the risk of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lining of the lung, peritoneal cancer develops in a membrane that covers the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma, and only about 300-500 cases diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Patients usually suffer from abdominal pain and may have a mass in their abdomen. This type of mesothelioma may cause nausea, weight loss, and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a misdiagnosis.

The doctors can detect mesothelioma through reviewing the medical history of the patient and performing a physical exam. They can also utilize imaging tests like X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can identify tumors and other cancer signs that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The staging is determined by the cell type and whether or whether the cancer has spread to other areas of the body.

Asbestos exposure is the most important risk factor. People who have worked in asbestos case-containing occupations, like electrical or plumbing work, or in construction and manufacturing are more likely to develop the disease. Even if a person does not work in any of these areas they could be exposed to asbestos to asbestos settlement through family members and other sources. Therefore, anyone who believes they could be at risk should talk to an expert. A mesothelioma specialist can assist those who have a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos Case exposure is a major mesothelioma risk factor, which accounts for as much as 80 percent of all cases. Exposure to asbestos can happen due to work, military service, or living with those who worked with asbestos. Asbestos particles are inhaled by those who are exposed to it. These irritate the linings and cause cancerous cells to form in the mesothelium. Mesothelioma can 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 at a higher risk of developing mesothelioma as compared to people who are younger or more. This is because mesothelioma typically lasts between 20 and 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to remember that mesothelioma is a possibility in those who were exposed to asbestos but did not engage directly with it. This is called indirect or secondary exposure to asbestos, and it can be just as dangerous as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more prone to. In addition, mesothelioma may be exacerbated by certain illnesses like 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 longer periods of time and work with it. Men are also more likely to have lived with someone who worked with asbestos and to have asbestos fibers on their clothing. Women are less likely to be exposed to asbestos, and they don't usually bring asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult disease to diagnose because the symptoms often resemble other conditions. This is why patients are sometimes mistakenly diagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history, including asbestos exposure. Doctors may also request an CT scan or chest X-ray to check for lumps, abnormalities and evidence of exposure to asbestos attorney. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels and magnetic resonance imaging, or MRI test, which makes use of magnets and radio waves to create detailed images of the inside of the body. Another way for doctors to detect mesothelioma is by performing the procedure of a surgical biopsy. When a biopsy is performed, doctors remove a tiny part of tissue from the pleura or the peritoneum to be examined further. A pathologist can then examine the tissue with microscopes to determine whether it has cancerous cells.

The type of mesothelial cell involved as well as the benign or malignant nature of the cells and the location, type and stage of the tumour, are used to classify the disease. Certain types of mesothelioma are more likely to spread or metastasize, so it is important to get a definite diagnosis so that doctors can treat the disease before it goes out of control.

Doctors can also perform tests in the laboratory on tumors to determine specific genes, proteins or other elements that can aid in describing cancer characteristics and plan treatment. These results are called staging.

Treatment

A mesothelioma diagnose can be frightening. However, it's important to remember that the disease is treatable, especially in its early stages. A lot of people suffering from mesothelioma live with the disease for a long time, without expanding.

Exposure to asbestos can cause mesothelioma by a variety of mechanisms. asbestos litigation fibers that are small enough to not be felt or viewed with the naked eyes are able to become airborne, irritating the lining of the lung (pleura). As time passes, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura surrounds the lungs and the heart and the abdomen. Mesothelium consists of cells that react to asbestos, causing it to inflame and develop scar tissue. Overtime, these changes lead to the development of malignant mesothelioma tumors.

A shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all indications of pleural msothelioma. In rare instances, the cancer can be spread to the tissues around the heart and reproductive organs.

If scans of imaging reveal an area of concern in the stomach or lungs doctors will recommend biopsies. The procedure involves the removal of small amounts of fluid or tumor for laboratory testing. The results can confirm a mesothelioma diagnosis and provide the most effective treatment plan.

There are a variety of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these methods. Participating in clinical trials of new mesothelioma treatment may also be beneficial for patients. To find out more, patients should speak to a mesothelioma specialist who has expertise in treating the condition.
