Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

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

This type of cancer typically caused by exposure to asbestos, which is a grouping of minerals made up of microscopic fibres. Once inhaled, these fibers stick inside the lung and cause irritation which results in scarring and DNA mutations. The pleura surrounds the chest cavity and lungs This means that these irritations can affect both the lungs as well as 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 who suffer from this cancer usually have an history of exposure to asbestos attorney in the workplace. Construction, manufacturing, and shipbuilding are the most common jobs that put people at high risk of developing pleural mesothelioma. People who served in the military are at a higher risk due to the frequent use of asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used to treat pleural adenocarcinoma. The stage a patient is in at diagnosis will aid their doctor in determining the best treatment plan for them. For instance, patients suffering from mesothelioma pleural stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma may spread to the liver, heart, or diaphragm. This could make the cancer more difficult to treat and increase the chances 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 as well as organs like the intestines and the liver. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma, with only about 300-500 cases diagnosed each year.

As with pleural asbestosis symptoms can take years to manifest. The majority of patients suffer from abdominal pain and an abdominal mass. Symptoms of this type of mesothelioma can also include nausea, weight loss and fever. Many of these symptoms can be mistaken for gastrointestinal problems and can lead to a mistaken diagnosis.

Generally speaking, doctors can detect mesothelioma after an extensive medical history and physical exam. They can also use imaging tests such as X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't visible on X-rays.

These test results allow doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage of the disease is determined based on the type of cell and whether or not the cancer has spread to other parts of the body.

Asbestos exposure is the main risk factor. People who have been in occupations that involve asbestos, like plumbing or manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if an individual isn't employed in one of these areas however, they may still be exposed through family members and other sources. Therefore, anyone who is concerned that they might be at risk should talk to a doctor. If they have an history of exposure to asbestos or mesothelioma, a specialist can help them find out more about their risk.

Risk Factors

Asbestos is the most significant mesothelioma-related risk factor. It is responsible for as much as 80percent of cases. Exposure to asbestos can happen due to work, military service, or living with people who have worked with asbestos lawyer. Asbestos particles are inhaled by those who are exposed to asbestos. These particles can cause irritation to the linings and cause cancerous cells to grow in the mesothelium. After exposure to asbestos mesothelioma is likely to be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics and age. People in their 40s or 50s are at a higher risk of developing mesothelioma compared to those who are younger or older. This is because mesothelioma typically lasts between 20 and 60 years after the initial time of exposure before cancer symptoms appear. It is also important to note that mesothelioma is a possibility in people who have been exposed to asbestos but didn't work with it directly. This is known as indirect or secondary exposure to asbestos legal and it can be just as dangerous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium and makes it more prone to asbestos. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is because men are more likely to work with asbestos and experience a a longer period of exposure than women. Additionally, men are more likely to live with someone who has had asbestos exposure and bring stray asbestos fibers home on their clothing. Women are less likely to come into exposure to asbestos and do not typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms can be similar to other diseases. This could lead to patients being misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors may 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 past asbestos settlement exposure such as plaques in the pleura (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 a magnetic resonance image or MRI test, which makes use of magnets and radio waves to create a series of detailed images of inside the body. A surgical biopsy is yet another method doctors use to diagnose mesothelioma. In a surgical biopsy doctors take a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist is then able to examine the tissue under a microscope to see if it has cancerous cells.

The mesothelial type involved as well as the benign or malignant nature of those cells as well as the location and stage of the tumor, are used to categorize the disease. Certain types of mesothelioma may be more likely to spread or metastasize and spread, therefore it is essential to have a clear diagnosis so doctors can treat the disease before it becomes out of control.

Doctors can also perform laboratory tests on tumors to identify specific genes, proteins or other factors that can help them describe cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. However, it's important to remember that the disease is treatable, especially in its early stages. Many mesothelioma patients live for years with the disease, without spreading to other parts of their body.

Asbestos exposure can trigger mesothelioma via various mechanisms. Asbestos fibres, tiny enough to be felt or seen with the naked eyes can be airborne, irritating the lining of the lung (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 the area that surrounds the heart and lungs, as well as the abdomen. Mesothelium is composed of cells that react to exposure to asbestos, causing it to inflame and create scar tissue. Overtime, these changes cause the development of malignant mesothelioma cancers.

Shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all signs of the pleural mesothelioma. In rare cases the cancer may be spread to the tissues around the heart and reproductive organs.

A doctor will request biopsy if imaging scans reveal a possible lung tumor or stomach. During the procedure doctors remove a small amount of fluid or tumor to allow for lab tests. The results will confirm a mesothelioma diagnosis and provide the best treatment option.

There are a variety of treatment for mesothelioma including surgery and chemotherapy. Most doctors use a combination of these treatments. Participating in clinical trials of mesothelioma treatments that are new could be beneficial for patients. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated the disease.
