Mesothelioma and Asbestos

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

The symptoms of these diseases might not manifest for years after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung lining (pleura). It is the most common mesothelioma form and is responsible for 70 to 79% of diagnosed cases. People with this condition feel chest pain and breath shortness, and they may feel the sensation of weight in the chest.

Exposure to asbestos, a group of minerals composed of microscopic fibers, usually causes this type of cancer. Once inhaled, the fibers are absorbed into the lung and cause irritation that leads to scarring and DNA mutations. The pleura surrounds the chest cavity and lungs, so these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Patients may also suffer from chest tightness, coughing or difficulty breathing. People with this cancer have a history that includes asbestos exposure at work. Construction, manufacturing, and shipbuilding are the most prevalent occupations that put people at high risk of developing pleural mesothelioma. People who were in the military are at a greater risk due to the frequent use of asbestos in Navy vessels and bunkers for the Army.

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

Peritoneal Mesothelioma

Contrary to pleural cancer that develops in the lung's lining, peritoneal cancer develops in the membrane that covers the abdominal cavity, which includes organs such as the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed each year which is lower than pleural asbestosis.

As with pleural asbestosis, symptoms can take years to manifest. Patients generally have abdominal pain, and may have a mass in their abdomen. Symptoms of this type of mesothelioma can also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to those experienced by digestive issues, which could result in incorrect diagnosis.

Generally, doctors can find mesothelioma by conducting a thorough medical history and physical exam. They can also use imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can show cancerous tumors or other symptoms of cancer that aren't visible on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. The stage is determined by the type of cell and whether the tumor has spread.

The most important risk factor for mesothelioma is asbestos exposure. People who have been in occupations that involve asbestos, such as plumbing or manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if a person isn't employed in one of these areas they could be exposed to asbestos to asbestos through family members and other sources. For this reason, anyone who is concerned that they might be at risk should talk to a doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can assist them in finding out more about their risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It accounts for as much as the 80% of cases. Exposure to asbestos can occur as a result of military service, work, or living with those who worked with asbestos. When exposed to asbestos, the particles can be inhaled into the lungs and abdomen. These particles can cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. After asbestos lawsuit exposure mesothelioma is likely to develop between 15 and 60 year.

Other risk factors include smoking, genetics and the advancing age. The people in their 40s or 50s are at greater chance of developing mesothelioma to those younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind, too, that mesothelioma can develop in people who have been exposed to asbestos without having directly worked with it. This is referred to as indirect or secondary exposure to asbestos. It is just as harmful as direct exposure.

Smoking increases the chance of mesothelioma developing, because it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos case for longer periods of time and work with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who worked with asbestos and to carry asbestos fibers on their clothing. Women are less likely to come exposed to asbestos and they don't usually carry asbestos on their clothes.

Diagnosis

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

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient which includes asbestos exposure. Doctors can also request an X-ray of the chest or CT scan to check for lumps or other abnormalities, and also to look for evidence of previous asbestos exposure like plaques in the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, that uses magnets and radio waves to create a series of detailed images of inside the body. Another way doctors can diagnose mesothelioma is to perform an operation called a biopsy. During a surgery biopsy doctors will remove a small piece of tissue from pleura or the peritoneum to be tested further. A pathologist is then able to look at the tissue under a microscope to see if it has cancerous cells.

The mesothelial type involved, the malignant or benign nature of these cells as well as the location the cancer, its type and the stage of the cancer are used to classify the disease. Some types of mesothelioma have greater risk of spreading or metastasizing and it's crucial to establish a clear diagnosis to ensure that the doctors can treat it before it gets out-of-control.

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

Treatment

A diagnosis of mesothelioma may be terrifying. However, it is important to remember that the cancer is treatable, particularly in its initial stages. Many people with mesothelioma live for years without the disease spreading to other parts of their body.

Asbestos exposure can cause mesothelioma by many mechanisms. Asbestos Legal fibers that are tiny enough to be felt or observed through the naked eye are able to become airborne, causing irritation to the lining of the lung (pleura). Over time the irritation can lead to the formation of scar tissue and eventually tumors.

The Pleura is a covering that protects the lungs, heart and abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They inflame the tissue and cause it to become scarred. These changes can eventually result in malignant mesothelioma tumors.

Breathing problems, chest discomfort or fluid buildup on the lungs are all indications of the pleural msothelioma. In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal a possible mass in the stomach or lungs doctors will recommend a biopsies. During the procedure, doctors take tiny amounts of fluid or tumor for lab testing. The results can confirm the diagnosis of mesothelioma and provide the best treatment plan.

There are many types of treatment for mesothelioma, such as chemotherapy and surgery. Most doctors use combinations of these treatments. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. To learn more, patients should speak with mesothelioma specialists who have expertise in treating the condition.
