Mesothelioma and Asbestos

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

It may take decades before symptoms begin to manifest after asbestos exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma occurs in the lung's outer lining, also known as the pleura. It is the most common mesothelioma form and accounts for 70% to 79% of diagnosed cases. Patients suffering from this condition feel chest pain and breath shortness and may also feel a sensation of heaviness in the chest.

This type of cancer is usually caused through exposure to asbestos, which is a grouping of minerals that are composed of microscopic fibers. These fibers, when inhaled can cause irritation and DNA mutations. The pleura surrounds the chest cavity and lungs, so these irritations can affect both the lungs and the heart of a person. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most common symptoms. Some patients may also suffer from chest tightness, coughing or difficulty breathing. People with this cancer often have an history of exposure to asbestos in the workplace. The most frequent jobs that put people at risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who have worked in the military could be at a higher risk because of the extensive asbestos usage in Navy ships and bunkers for the army.

The most common staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage that the patient is in at the moment of diagnosis will determine what treatment plan they should receive. For instance, patients suffering from a pleural mesothelioma in stage three or four have a poorer prognosis than those in lower stages. Stage four mesothelioma is often spread to the diaphragm, the liver and/or a person's heart. This makes it more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum - a membrane that lines the abdominal cavity and organs like the intestines and liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed annually which is lower than the pleural asbestosis.

Like pleural mesothelioma, symptoms can take years to show. Patients typically suffer from abdominal pain and could also experience a mass in their abdomen. This mesothelioma type can also cause nausea, weight loss and fever. Many of these symptoms can be mistaken for gastrointestinal problems and can lead to a misdiagnosis.

The doctors can detect mesothelioma through looking over the medical history of the patient and performing a physical examination. They can also utilize imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors and other signs of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage and suggest treatment options. The stage of the disease is determined based on the type of cell and whether or the cancer has spread to other regions of the body.

Asbestos exposure is the biggest risk factor. People who have worked in professions that require asbestos, such as plumbing manufacturing, electrical work, or construction, are at a higher risk of developing the disease. Even if someone isn't employed in one of these fields they could still be exposed through family members and other sources. For this reason, anyone who believes they could be at risk should talk to an experienced doctor. A mesothelioma specialist can assist those who have had a experience with asbestos attorney to understand more about their risk.

Risk Factors

asbestos lawyer is the main risk factor for mesothelioma. It accounts for up to 80% of all cases. Exposure to asbestos can happen as a result of military service, work, or living with people who have worked with asbestos. Asbestos particles can be breathed in by those who are exposed to asbestos. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. After asbestos settlement exposure mesothelioma is likely to be diagnosed between 15 and 60 year.

Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or more senior. Mesothelioma can take between 20 and 60 years to show signs of cancer after the first exposure. It is important to remember that mesothelioma may develop in people who have been exposed to asbestos claim, but did not deal with it directly. This is referred to as indirect or secondary asbestos exposure, and is as dangerous as direct asbestos 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, including asbestosis and pneumonia. It is also important to know that mesothelioma is more common in men than women. This is due to the fact that men are more likely to work with asbestos and experience a a longer period of exposure than women. Men are also more likely to have lived with someone who worked with asbestos and to carry Asbestos Case fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are frequently similar to other illnesses. This is why patients are sometimes wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical history including asbestos exposure. Doctors may also request an CT scan or chest X-ray to check for abnormalities, lumps and evidence of asbestos exposure. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, which makes use of magnets and radio waves in order to produce a series of precise images of the inside of the body. A surgical biopsy is another method for doctors to identify mesothelioma. In a surgical biopsy, doctors remove a tiny piece of tissue from pleura or the peritoneum to be further examined. A pathologist can then examine the tissue under an magnifying glass to determine if it contains cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of the cells and the location and stage of the cancer are used to categorize the disease. Some types of mesothelioma have greater risk of spreading or metastasizing and it's crucial to determine the type of mesothelioma so doctors can treat it prior to it becoming out of control.

Doctors may also conduct tests in the lab on tumors to determine specific proteins, genes or other elements that will help them identify cancer characteristics and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma may be terrifying. It is important to remember, however, that cancer can be treated particularly in its initial stages. Many people with mesothelioma can live with the disease for a long time without spreading.

Asbestos exposure can trigger mesothelioma via many mechanisms. Asbestos particles, which are too small to detect or feel by the naked eye can become airborne and irritate the lung's lining (pleura). As time passes irritation can lead to formation of scar tissue which leads to changes in the structure of cells which eventually lead to tumors.

The pleura covers the lungs and the heart and also the abdomen. Mesothelium is made up of cells that react to exposure to asbestos which causes it to become inflamed and develop scar tissue. These changes can lead to malignant mesothelioma tumours.

Breathing problems, chest pain or fluid accumulation on the lungs are all indications of pleural Msothelioma. In rare instances cancer may spread to the tissues that surround the reproductive organs and the heart.

If imaging scans show a possible mass in the stomach or lungs doctors will recommend a biopsies. In the course of the procedure, doctors remove some of the liquid or tumor for lab tests. The results can confirm a mesothelioma diagnosis, and determine the most effective treatment plan.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors rely on the combination of these methods. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatment. To learn more about the trials, patients should speak to mesothelioma specialists who have had experience treating the disease.
