Mesothelioma and Asbestos

Asbestos, a mineral that naturally occurs in the form of thin, long fibers. Workers who are exposed to asbestos regularly are at risk of developing mesothelioma or other lung diseases of different types.

Symptoms of these diseases may not be evident for a long time after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that develops in the lung's outer lining (pleura). It is the most prevalent mesothelioma type, accounting for up 70 to 79% of diagnosed cases. This condition causes chest pain, breath shortness and a feeling heaviness.

This kind of cancer is often caused through exposure to asbestos, which is a grouping of minerals made up of microscopic fibres. When inhaled, these fibers can cause irritation and DNA mutations. The pleura covers the lungs and chest cavity, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Patients may have coughing problems, trouble breathing or chest tightness. Patients with this cancer have a history that includes asbestos exposure at work. The most frequent jobs that expose workers to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. Individuals who have served in the military are at a higher risk due to the extensive use asbestos in Navy vessels and bunkers in the Army.

The most common staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage that the patient is in at the time of diagnosis can help determine what treatment plan they should receive. Patients who have pleural mesothelioma which is in stage three or stage four will have a worse outlook than those who are in a less advanced stage. Mesothelioma in stage four can develop into the liver, heart or diaphragm. This makes the cancer more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lung's lining it develops in the membrane that covers the abdominal cavity, including organs such as the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. There are only 300-500 cases diagnosed annually which is lower than pleural asbestosis.

As with pleural mesothelioma symptoms can take a long time to manifest. Typically, patients are afflicted with abdominal pain as well as an abdominal mass. This mesothelioma type can also cause nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues which can lead to a misdiagnosis.

Generally, doctors can find mesothelioma through a thorough medical history and physical exam. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can reveal tumors and other indications of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also suggest treatments. The staging is determined by the cell type and whether or not the tumor has spread to other parts of the body.

The most important mesothelioma-related risk factor is asbestos exposure. People who have been exposed to asbestos in occupations, like plumbing or electrical work, or in construction, manufacturing and manufacturing, are more likely to contract the disease. Even if a person does not work in one of these fields however, they may still be exposed to asbestos through family members and other sources. Anyone who suspects that they are at risk should talk to an expert. If they have an history of exposure to asbestos attorney and mesothelioma is a concern, a specialist will assist them in learning more about the risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma, which accounts for as much as 80 percent of cases. Exposure to asbestos lawyer can occur due to work, military service or by living with a person who works with asbestos or used to do such. When exposed to asbestos case, the particles are able to be inhaled into lungs and abdomen. These particles can cause irritation to the linings, causing cancerous cells to form in the mesothelium. After exposure to asbestos mesothelioma is likely to be diagnosed between 15 and 60 years old.

Other risk factors include genetics, smoking and age. People in their 40s or 50s are more at risk of developing mesothelioma compared to those who are younger or older. It is because mesothelioma generally takes 20 to 60 years from the first time of exposure before the first signs of cancer appear. It is important to note that mesothelioma can be present in people who have been exposed to asbestos without having worked with it directly. This is referred to as indirect or secondary exposure to Asbestos Case, and it can be just as dangerous as direct exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it damages the mesothelium and makes it more susceptible to asbestos. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos and experience a more exposure than women. Men are also more likely to have lived with someone who has worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and do not typically carry asbestos on their clothes.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being frequently similar to other illnesses. This can lead to victims being wrongly diagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical background including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray to look for lumps, abnormalities, and evidence of exposure to asbestos. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels as well as a magnetic resonance imaging, or MRI, test that uses magnets and radio waves to create detailed images of the interior of the body. Another method doctors use to diagnose mesothelioma is by performing an operation called a biopsy. In a surgical biopsy doctors will remove a small piece of tissue from the pleura or the peritoneum, to be examined further. A pathologist can then look at the tissue under microscopes to determine if it has cancerous cells.

Mesothelioma can be classified based on the mesothelial type involved, whether those cells are malignant or benign and the location of the tumor, its type, and the stage of the cancer. Certain types of mesothelioma are more likely to grow or spread, so it is important to establish a definitive diagnosis so that doctors can treat the disease before it gets out of control.

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

Treatment

A diagnosis of mesothelioma can be terrifying. However, it is important to remember that the disease can be treated, particularly in its early stages. Many patients with mesothelioma survive for years with the disease without it spreading to other areas of their body.

Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibres, small enough to not be felt or observed with the naked eyes are able to become airborne and irritate the lung's lining (pleura). As time passes irritation can lead to formation of scar tissue which causes changes in the structure of cells that can eventually grow into tumors.

The pleura is the area that surrounds the heart and lungs and also the abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. These changes eventually cause mesothelioma cancers.

The symptoms of pleural mesothelioma are breathlessness, chest pain or an accumulation of fluid on the lungs (pleural effusion). In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.

A doctor may request a biopsy if imaging scans show a potential mass in the lungs or stomach. During the procedure, doctors remove a small sample of the fluid or tumor for laboratory tests. The results will confirm the diagnosis of mesothelioma and indicate the best treatment option.

There are many types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. Most doctors utilize a combination of these methods. Patients could also benefit from participating in a clinical study of new mesothelioma treatment. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated mesothelioma.
