Mesothelioma and Asbestos

Asbestos is a natural mineral that comes in thin, long fibres. Workers who are exposed asbestos on a regular basis are at risk of developing mesothelioma as well as other lung diseases.

It could take a long time before symptoms begin to manifest after asbestos exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, also known as pleura. It is the most common mesothelioma form and accounts for 70% to 79% all diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of heaviness.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, typically causes this type of cancer. These fibers, when inhaled can cause irritation and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs and therefore, these irritations could affect both the lungs and a person's heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Some patients may also experience chest tightness, coughing or difficulty breathing. People with this cancer have a history that includes asbestos litigation exposure at work. The most prevalent jobs that put people at risk of developing pleural cancer are construction, manufacturing and shipbuilding. People who have served in the military are at an especially high risk because of the extensive asbestos use in Navy ships and bunkers used by the army.

The most popular staging system for pleural mysothelioma has been the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has upon diagnosis will aid their doctor in determining the best treatment plan for them. Patients who have pleural mesothelioma which is in stage three or four will suffer a more negative prognosis compared to those who are in a lower stage. Stage four mesothelioma is often spread to the diaphragm, the liver or even a person's heart. This can make the cancer more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum - an elongated membrane that covers the abdominal cavity as well as organs like the intestines and the liver. Similar to pleural mesothelioma, asbestos exposure is the primary cause of peritoneal mesothelioma. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Patients usually have abdominal pain, and may have a mass in their abdomen. This mesothelioma type can also cause nausea, weight loss and fever. Many of these symptoms are similar to those of gastrointestinal issues, which can lead to misdiagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and conducting a physical exam. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can show tumors and other indications of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatments. The stage of the disease is determined based on the cell type and whether or not the cancer has spread to other parts of the body.

Asbestos exposure is the most important risk factor. People who have been in occupations that require asbestos, such as plumbing manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if they aren't employed in these areas they may be exposed to asbestos through family members or other sources. Anyone who thinks they're at risk should consult an expert. A mesothelioma specialist can assist those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It is responsible for up to 80% of all cases. Exposure to asbestos law can happen through work, military service, or living with those who worked with asbestos. When exposed to asbestos attorney, small particles are able to be inhaled into lungs and abdomen. They can cause irritation to the linings of the abdomen and cause cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are more likely develop mesothelioma than 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 keep in mind that mesothelioma may be present in people who have been exposed to asbestos, but without having directly worked with it. This is referred to as indirect or secondary asbestos exposure, and is just as harmful as direct asbestos exposure.

Smoking increases the risk of getting mesothelioma because it causes mesothelium damage and makes it more susceptible to asbestos. Additionally, mesothelioma can be exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to know that mesothelioma is more prevalent 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 live with someone who worked with asbestos and carry asbestos fibers that have escaped home on their clothes. Women tend to have less contact with asbestos and do not typically carry asbestos lawsuit home on their clothing.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being frequently similar to other illnesses. This could lead to patients being misdiagnosed.

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

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels and magnetic resonance imaging, also known as MRI test that uses radio waves and magnets to create detailed images of the interior of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. During a surgery biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum, to be tested further. A pathologist then examines the tissue under an magnifying glass to determine if it contains cancerous cell.

The type of mesothelial cells involved, the malignant or benign nature of these cells and the location, type and stage of the cancer are used to categorize the disease. Some types of mesothelioma have greater chance of metastasizing or spreading, so it's important to establish a clear diagnosis to ensure that the doctors can treat it before it becomes out-of-control.

Doctors can also perform tests in the laboratory on tumors in order to determine specific proteins, genes, or other factors which can aid in describing cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is crucial to remember, however, that cancer can be treated, particularly in its early stages. Many mesothelioma patients live for years without the disease spreading to other organs of their body.

Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibers, too small to see or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). As time passes, the irritation causes the formation of scar tissue which can cause changes in the cell structure that eventually develop into tumors.

The pleura surrounds the lungs and heart and the abdomen. Mesothelium is composed of cells that react to exposure to asbestos which causes it to become inflamed and form scar tissue. These changes can lead to malignant mesothelioma tumours.

Symptoms of pleural mesothelioma include breathing problems and chest pain, or the accumulation of fluid in the lung (pleural effusion). In rare cases cancer can spread to the tissues that surround the reproductive organs as well as the heart.

A doctor will request biopsy if scans show the possibility of a tumor in the lungs or stomach. During the procedure doctors remove small amounts of fluid or tumor to allow for laboratory testing. The results can confirm the diagnosis of mesothelioma and provide the best treatment plan.

There are many types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ the combination of these treatments. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial for patients. Patients can learn more by consulting a mesothelioma specialist who has treated mesothelioma.
