Mesothelioma and Asbestos

Asbestos, a mineral that occurs naturally in the form of long, thin fibers. People who are exposed to asbestos risk developing lung diseases, such as mesothelioma.

The symptoms of these diseases might not show up for decades after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung lining (pleura). It is the most frequent form of mesothelioma and is responsible for 70 to 79% of diagnosed cases. The condition can cause chest discomfort, shortness of breath and a feeling of heavyness.

This kind of cancer is typically caused by exposure to asbestos, which is a collection of minerals made up of microscopic fibres. The fibers, when inhaled, cause irritation and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most frequent symptoms of pleural melanoma are chest pain and breath shortness. Patients may also suffer from chest tightness, coughing or difficulty breathing. Patients with this type of cancer have a history that includes asbestos exposure at work. Manufacturing, construction and shipbuilding are among the most frequent occupations which put people at risk chance of developing pleural mesothelioma. People who have served in the military could be at a higher risk due to the widespread asbestos use in Navy ships and bunkers used by the army.

The most common staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage that the patient is in at the time of diagnosis can help determine what treatment plan they will receive. Patients with pleural mesothelioma that is in stage three or stage four will have a less favorable outlook than those who are in a less advanced stage. Mesothelioma in stage four can be spread to the liver, heart or diaphragm. This makes it more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum -- a membrane that lines the abdominal cavity and organs like the liver and intestines. Like pleural mesothelioma, exposure to asbestos is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed annually this is less than the pleural asbestosis.

As with pleural asbestosis symptoms can take years to show. Most patients experience abdominal pain and an abdominal mass. The symptoms of this type of mesothelioma may also include nausea, weight loss and fever. A lot of these symptoms are similar to those of gastrointestinal issues, which can cause incorrect diagnosis.

Generally, doctors can find mesothelioma through an extensive health history and physical examination. They can also use imaging tests like Xrays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors and other cancer signs that are not evident on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They also offer treatments. The stage of the disease is determined based on the type of cell and whether or the cancer has spread to other areas of the body.

Asbestos exposure is the biggest risk factor. People who have been exposed to asbestos in jobs, such as plumbing or electrical work, or in manufacturing and construction, are more likely to develop the disease. However, even if people aren't employed in these areas they could be exposed to asbestos compensation through family members or other sources. Therefore, anyone who believes they could be at risk should talk to an experienced doctor. A mesothelioma expert can help those who have had a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It accounts for up to 80% of all cases. Exposure to asbestos may occur as a result of work, military service or by living with someone who is exposed to asbestos or was previously exposed to doing the same. Asbestos particles can be breathed in by people who are exposed to it. These particles can cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos claim.

Other risk factors include smoking, genetics, and age. People in their 40s and 50s are more likely to develop mesothelioma than those who are younger or older. It is because mesothelioma generally takes 20 to 60 years from the initial exposure to asbestos before the first signs of cancer appear. It is important to remember that mesothelioma can develop in people who were exposed to asbestos, but did not engage directly with it. This is referred to as secondary or indirect Asbestos Legal exposure. It can be just as harmful as direct asbestos exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more prone to. Furthermore, mesothelioma is exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to know that mesothelioma is more common in men than women. This is because men are more likely to be exposed to asbestos and endure a more exposure than women. Additionally, men are more likely to live with someone who was exposed to asbestos and bring stray asbestos fibers home on their clothes. Women are less likely to be exposed to asbestos and they are less likely to carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms are often similar to other diseases. This is why patients are sometimes mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history, including asbestos exposure. Doctors can also order an X-ray of the chest or CT scan to check for lumps or other abnormalities, and also to look for evidence of asbestos case exposure in the past 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 a magnetic resonance image or MRI test, which makes use of radio waves and magnets in order to create a series detailed images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist can then examine the tissue under a magnifying lens to determine if it contains cancerous cell.

Mesothelioma is classified based on the mesothelial type involved, whether those cells are benign or malignant and the location of the tumor, its type, and the stage of the tumor. Certain mesothelioma types have greater chance of metastasizing or spreading, so it's important to establish a clear diagnosis to ensure that the doctors can treat it prior to it becoming out of control.

Doctors may also conduct laboratory tests on a tumor to find specific proteins, genes or other elements that help them understand the cancer's characteristics and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma may be terrifying. It is important to remember that cancer can be treated particularly in its early stages. Many people with mesothelioma live for years with the disease without it spreading to other organs of their body.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos fibers, which are too small to be able to see or feel with the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). Over time, the irritation causes the formation of scar tissue which leads to changes in the structure of cells that eventually develop into tumors.

The pleura is a protective covering that surrounds the abdomen, heart, and lungs. Mesothelium is made up of cells that react to exposure to asbestos legal which causes it to become inflamed and create scar tissue. These changes can eventually lead to malignant mesothelioma tumours.

A shortness of breath, chest pain or fluid accumulation on the lungs are all signs of the pleural mesothelioma. In rare cases, the cancer can spread to the tissues surrounding the heart and reproductive organs.

A doctor will order biopsy if imaging scans show the possibility of a mass in the lungs or stomach. During the procedure, doctors take a small sample of the fluid or tumor for laboratory analysis. The results can confirm the diagnosis of mesothelioma and help determine the best treatment plan.

There are a variety of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. The majority of doctors use a combination of these methods. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatment. To learn more, patients should speak with mesothelioma specialists who have experience treating the condition.
