Guide To Mesothelioma And Asbestos: The Intermediate Guide On Mesothelioma And Asbestos

Mesothelioma and Asbestos

Asbestos is a natural mineral that comes in thin, long fibres. Workers who are regularly exposed to asbestos risk developing lung diseases like mesothelioma.

The symptoms of these diseases might not manifest for years after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, or the pleura. It is the most prevalent mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. This condition causes chest pain, shortness of breathe, and a feeling of heavyness.

Exposure to asbestos, a family of minerals composed of microscopic fibers, typically causes this kind of cancer. The fibers, when inhaled can cause irritation and DNA mutations. The pleura surrounds the lungs and chest cavity This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Some patients also experience coughing, difficulty breathing, or chest tightness. People with this cancer have a history that includes asbestos exposure at work. The most prevalent jobs that expose people to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who have worked in the military could be at risk due to the widespread asbestos usage in Navy ships and army bunkers.

The most popular staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that a patient is in at the time of diagnosis will help determine what treatment plan they should follow. Patients who have pleural mesothelioma which is in stage three or four will suffer a more negative outlook than those who are in a less advanced stage. Stage four mesothelioma often spreads to the diaphragm, liver or even a person's heart. This could make the cancer more difficult to treat and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma is found in the peritoneum -- an elongated membrane that covers the abdominal cavity as well as organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. Only 300-500 cases are diagnosed annually this is less than pleural asbestosis.

As with pleural mesothelioma symptoms can take a long time to manifest. The majority of patients experience abdominal pain and a mass in the abdomen. Symptoms of this type of mesothelioma may also include nausea, weight loss and fever. Many of these symptoms could be misinterpreted as digestive issues and can lead to a false diagnosis.

Generally, doctors can find mesothelioma after an exhaustive medical history and physical exam. Imaging tests like X-rays or CT scans are a way to detect mesothelioma. These tests can reveal tumors and other signs of cancer that aren't visible on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatments. Staging is determined based on the type of cells and whether or whether the tumor has spread to other areas of the body.

Asbestos exposure is the main risk factor. People who have worked in professions which require asbestos, like plumbing manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if a person isn't employed in any of these areas however, they may be exposed to asbestos law through family members and other sources. Anyone who suspects that they may be at risk should talk to an expert. A mesothelioma specialist can help those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, accounting for up to 80 percent of all cases. Exposure to asbestos can occur due to military service, work or living with those who worked with asbestos legal (Ecommk.Com). Asbestos particles can be breathed in by people who are exposed to asbestos compensation. These particles can cause irritation to the linings, causing cancerous cells to develop 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 and 50s are at a higher risk of developing mesothelioma as compared to those who are younger or older. Mesothelioma can take between 20 and 60 years to manifest cancer symptoms after the first exposure. It is important to remember that mesothelioma can develop in people who have been exposed to asbestos but did not deal with it directly. This is known as secondary or indirect exposure to asbestos lawsuit and it is just as harmful as direct exposure.

Smoking can increase the likelihood of developing mesothelioma since it causes mesothelium damage and makes it more susceptible to asbestos. Mesothelioma can also be caused by certain illnesses such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more prevalent in males 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 live with someone who has worked with asbestos and carry asbestos fibers that have escaped home on their clothes. Women tend to be less exposed to asbestos and they are less likely to carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to identify because the symptoms often resemble other conditions. Because of this, victims are often mistakenly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient which includes asbestos exposure. Doctors will also recommend an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques in the pleura, thickened pleura 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 uses radio waves and magnets to create precise images of the inside of the body. A surgical biopsy is yet another method doctors use to diagnose mesothelioma. When a biopsy is performed doctors take a tiny part of tissue from the pleura or the peritoneum, to be further examined. A pathologist can examine the tissue under microscopes to determine if it is contaminated with 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 tumor, are used to classify the disease. Certain types of mesothelioma are more likely to grow or spread, so it is important to have a clear diagnosis to ensure that doctors are able to treat the disease before it goes out of control.

Doctors can also run tests in the laboratory on a tumor to find specific genes, proteins and other factors which can help them identify the cancer's characteristics and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. However, it's important to remember that the cancer is treatable, especially in its early stages. Many patients with mesothelioma live with the disease for a long time, without spreading.

Exposure to asbestos may cause mesothelioma in many ways. Asbestos fibres, small enough to not be felt or seen with the naked eyes, can become airborne, causing irritation to the lung's lining (pleura). As time passes, the irritation leads to the formation of scar tissue and eventually tumors.

The Pleura is a covering that protects the lungs, heart and abdomen. Mesothelium is made up of cells that react to exposure to asbestos, causing it to inflame and form scar tissue. These changes eventually result in malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness, chest pain or an accumulation of fluid in the lung (pleural effusion). In rare instances the cancer may spread to the tissues surrounding the heart and reproductive organs.

A doctor will request biopsy if scans show the possibility of a mass in the lungs or stomach. In the course of the procedure, doctors remove a small amount of liquid or tumor for tests in the laboratory. The results can confirm a mesothelioma diagnosis and determine the best treatment plan.

There are a variety of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors use combinations of these treatments. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial to patients. To learn more, patients should speak to a mesothelioma specialist who has experience treating the condition.
