Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that comes in thin, long fibres. Workers who are exposed asbestos regularly risk developing mesothelioma and other lung diseases of different types.

It could take a long time for symptoms to show up after asbestos exposure. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that develops in the outer lung the lining (pleura). It is the most prevalent mesothelioma type and accounts for 70% to 79% all diagnosed cases. Patients with this disease feel chest pain and shortness of breath and may also feel a sensation of heaviness in the chest.

This type of cancer usually caused by exposure to asbestos, which is a collection of minerals that are made up of microscopic fibres. These fibers, when inhaled cause irritation and DNA mutations. The pleura covers the chest cavity and lungs This means that these irritations can affect both the lungs and the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 year after exposure.

The most frequent symptoms of pleural melanoma are chest discomfort and shortness of breath. Some patients may also experience chest tightness, coughing or difficulty breathing. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most common jobs that put people at a high chance of developing pleural mesothelioma. Individuals who have been in the military may be at risk due to the frequent asbestos use in Navy ships and army bunkers.

The most common staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at at diagnosis will help their doctor determine the most effective treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will suffer a more negative prognosis than those 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 increases the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum, it is a membrane that lines the abdominal cavity and organs like the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the cause of peritoneal msothelioma. The disease is much 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. The majority of patients are afflicted with abdominal pain as well as an abdominal mass. The symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. A lot of these symptoms are similar to symptoms of digestive problems, which can lead to incorrect diagnosis.

Generally, doctors can find mesothelioma by conducting an exhaustive health history and physical exam. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can detect tumors as well as other signs of cancer which aren't visible on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatments. The stage is determined by the type of cell and whether the cancer has spread.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos-related occupations, like plumbing or electrical work, or in construction, manufacturing and manufacturing, are more likely to develop the disease. However, even if individuals do not work in these areas, they can still be exposed to asbestos legal through family members or other sources. Anyone who believes they are at risk should talk to an expert. A mesothelioma specialist can assist those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos is the primary mesothelioma-related risk factor. It is responsible for up to the 80% of cases. Exposure to asbestos can happen as a result of military service, work or living with people who have worked with asbestos compensation. When exposed to asbestos, the particles can be inhaled into the abdomen and lungs. These particles can cause irritation to the linings and can cause cancerous cells to develop in the mesothelium. Following exposure to asbestos, mesothelioma may occur between 15 and 60 years old.

Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. It is because mesothelioma generally occurs between 20 and 60 years from the first exposure before symptoms of cancer begin to manifest. It is important to remember, too, that mesothelioma could be present in those who have been exposed to asbestos without having worked with it directly. This is called indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It can also make it more vulnerable. Mesothelioma can also be caused by certain illnesses such as 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 asbestos for longer periods of time. Men are also more likely to have lived with someone who has worked with asbestos and to carry asbestos fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos on their clothing.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being often similar to other diseases. Because of this, victims are often misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos compensation exposure. Doctors can also order an X-ray of the chest or CT scan to check for lumps and other abnormalities, and also to look for evidence of previous asbestos exposure such as pleural plaques (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels, and a magnetic resonance imaging, also known as MRI, test that uses radio waves and magnets to create detailed images of the inside of the body. Another way doctors can diagnose mesothelioma is by performing an operation called a biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist can examine the tissue under microscopes to determine if it has cancerous cells.

The mesothelial type involved as well as the benign or malignant nature of these cells and the location, type and stage of the tumour, are used to categorize the disease. Certain mesothelioma types have an increased risk of metastasizing or spreading, so it's important to get a definitive diagnosis so that doctors can treat it prior to it becoming out of control.

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

Treatment

A mesothelioma diagnose can be frightening. However, it's important to remember that the cancer can be treated, particularly in its early stages. Many people with mesothelioma live for many years without the disease spreading to other parts of their body.

Exposure to asbestos can trigger mesothelioma through a variety of ways. asbestos case (web) fibers, which are too small to see or feel with the naked eye, can become airborne and irritate the lung's lining (pleura). In time irritation leads to formation of scar tissue which leads to changes in the cell structure that eventually develop into tumors.

The pleura surrounds the lungs and the heart and the abdomen. Mesothelium consists of cells that react to exposure to asbestos and cause it to enflame and create scar tissue. As time passes, these changes result in the growth of malignant mesothelioma cancers.

The signs of pleural mesothelioma can include breathing problems and chest pain, or a buildup of fluid in the lungs (pleural effusion). In rare instances the cancer may spread to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal an underlying mass in the lungs or stomach doctors will recommend biopsies. During the procedure, doctors take small amounts of the tumor or fluid for lab testing. The results can confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are a variety of treatment for mesothelioma including surgery and chemotherapy. The majority of doctors use the combination of these methods. Patients could also benefit from enrolling in a clinical trial of new mesothelioma treatments. To find out more, patients should speak to mesothelioma specialists who have experience treating the condition.
