Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that develops in the lung's outer lining (pleura). It is the most frequent mesothelioma type and is responsible for 70 to 79% of diagnosed cases. People with this condition experience pain in the chest and breathlessness, and they may feel a sensation of heaviness in the chest.

Exposure to asbestos, a class of minerals composed of microscopic fibers causes this type of cancer. When inhaled, these fibers are absorbed into the lungs and cause irritation that causes scarring and DNA mutations. The pleura covers the chest cavity and lungs This means that these irritations can 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 frequent symptoms of pleural melanoma are chest pain and breath shortness. Some patients have coughing problems, trouble breathing, or chest tightness. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most frequent occupations that put people at a high danger of developing pleural melanoma. People who served in the military are at greater risk due the widespread use of asbestos in Navy vessels and bunkers for the Army.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at the time of diagnosis will help determine what treatment plan they should receive. For instance, patients who have a pleural mesothelioma in stage three or four have a poorer prognosis than patients with lower stages. Stage four mesothelioma often spreads to the diaphragm, liver and/or a person's heart. This can make it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lung's lining it develops in a membrane that surrounds the abdominal cavity, including organs like the liver and intestines. Similar to pleural mesothelioma, asbestos exposure is the primary reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to manifest. Patients usually suffer from abdominal pain and could also experience a mass in their abdomen. This mesothelioma type can cause nausea, weight loss and fever. A lot of these symptoms are similar to those of digestive problems, which can lead to incorrect diagnosis.

Generally speaking, doctors can detect mesothelioma after an exhaustive medical history and physical exam. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. These tests can reveal tumors, as well as other symptoms of cancer that aren't apparent on an X-ray.

These test results allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. Staging is determined based on the type of cells and whether or the cancer has spread to other parts of the body.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos-related professions, such as plumbing or electrical work, or in construction and manufacturing are more likely to contract the disease. However, even if people aren't employed in these areas, they can still be exposed to asbestos case through family members or other sources. Therefore, anyone who is concerned that they might be at risk should talk to an expert. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will help them find out more about the risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, accounting for up to 80 percent of all cases. Exposure to asbestos can occur due to work, military service or by living with someone who is exposed to asbestos or was previously exposed to doing such. Asbestos particles are inhaled by people who are exposed to it. These particles irritate the linings of the abdomen, which causes cancerous cells to form in the mesothelium. After exposure to asbestos, mesothelioma may develop between 15 and 60 years.

Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or older. This is because mesothelioma typically takes 20 to 60 years after the initial exposure before the first signs of cancer appear. It is important to keep in mind that mesothelioma may 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. It can be just as harmful as direct asbestos exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It can also make it more vulnerable. In addition, mesothelioma may be exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to note that mesothelioma occurs more frequently in males than females. This is due to the fact that men are more likely to work with asbestos and experience a an extended period of exposure than women. Men are also more likely to have lived with someone who worked with asbestos, and to have asbestos legal (special info) fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos around on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma since its 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 an examination and write down a patient's medical history, including asbestos exposure. Doctors may also order an X-ray of the chest or CT scan to detect lumps and other abnormalities as well as evidence of past asbestos exposure such as pleural plaques (thickened pleura with calcium deposits) and the formation of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which uses magnets and radio waves to create a series detailed images of the inside of the body. A surgical biopsy is another method for doctors to identify mesothelioma. During a surgical biopsy, doctors remove a small piece of tissue from the pleura or peritoneum for further testing. A pathologist then examines the tissue using an magnifying glass to determine if it is a cancerous cells.

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

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

Treatment

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

Exposure to asbestos can cause mesothelioma by many mechanisms. Asbestos particles, which are too small to be able to see or feel by the naked eye can become airborne and cause irritation to the lining of the lungs (pleura). Over time, the irritation causes the formation of scar tissue, which causes changes in the cell structure which eventually lead to tumors.

The Pleura is a protective layer that protects the abdomen, heart, and lungs. Mesothelium is composed of cells that react to asbestos, causing it to inflame and develop scar tissue. As time passes, these changes result in the growth of malignant mesothelioma cancers.

A shortness of breath, chest discomfort or fluid buildup on the lungs are all signs of pleural mesothelioma. In rare instances the cancer may grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal a possible mass in the lungs or stomach the doctor will request biopsies. During the procedure, doctors will remove small amounts of the tumor or fluid for lab tests. The results can confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are a variety of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. The majority of doctors employ combinations of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma treatment. Patients can find out more by consulting a mesothelioma expert who has treated the disease.
