Mesothelioma and Asbestos

Asbestos, a mineral that naturally forms in the form of thin, long fibers. People who are regularly exposed to asbestos may develop lung diseases, such as mesothelioma.

Symptoms of these diseases may not show up for decades after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining or the pleura. It is the most common mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. Patients suffering from this condition suffer from chest pain and breath shortness and may experience an ache or heaviness in the chest.

Exposure to asbestos claim, a class of minerals made of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled can cause irritation and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Some patients also experience coughing, difficulty breathing or chest tightness. People with this cancer often have previous exposure to asbestos in the workplace. The most prevalent jobs that expose workers to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. Individuals who have served in the military are at a greater risk due to the widespread use of asbestos in Navy vessels and bunkers for the Army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used to treat pleural adenocarcinoma. The stage that a patient is at upon diagnosis will assist their doctor in determining the most effective treatment plan for them. 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 often spreads to the liver, diaphragm or even the heart of a patient. This could make the cancer more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lining of the lung the peritoneal cancer is a result of a membrane that surrounds the abdominal cavity, including organs like the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to show. Most patients are afflicted with abdominal pain as well as abdominal swelling. This mesothelioma type can also cause nausea, weight loss and fever. A lot of these symptoms are similar to symptoms of digestive issues, which could cause misdiagnosis.

Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical exam. They can also use imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can detect tumors and other signs of cancer that are not visible on X-rays.

These tests enable doctors to diagnose mesothelioma, determine the stage of the disease and suggest treatment options. The staging is determined by the type of cell and whether or not the cancer has spread to other areas of the body.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have worked in asbestos-containing professions, such as plumbing or electrical work, or in manufacturing and construction, are more likely to develop the disease. Even if they do not work in these areas they may be exposed to asbestos through relatives or other sources. Anyone who thinks they may be at risk should talk to an expert. If they have any history of exposure to asbestos attorney, a mesothelioma specialist can help them find out more about the risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It is responsible for up to 80percent of cases. Exposure to asbestos can happen through work, military service or through living with a person who works with asbestos or has previously done such. Asbestos particles are inhaled by those who are exposed to it. These particles irritate the linings of the lungs, causing cancerous cells to develop 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 to be diagnosed with mesothelioma compared to those who are younger or older. This is because mesothelioma usually lasts between 20 and 60 years after the initial exposure to asbestos before the first signs of cancer appear. It is also important to know that mesothelioma may develop in those who were exposed to asbestos case (a cool way to improve) but did not work with it directly. This is known as indirect or secondary exposure to asbestos, and it can be just as dangerous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it causes mesothelium damage and makes it more susceptible to asbestos. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. It is also important to remember that mesothelioma occurs more frequently in males than females. This is due to men being more likely to be exposed to asbestos and endure a an extended period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos lawsuit and rarely carry asbestos around 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.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform a physical exam and take notes on the medical history of a patient, including asbestos attorney exposure. Doctors may also request a CT scan or chest X-ray to look for lumps, abnormalities and evidence of exposure to asbestos. These include plaques in the pleura, 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, also known as MRI, test, which uses radio waves and magnets to make a series of detailed images of the inside of the body. Another way doctors can diagnose mesothelioma is by performing an operation called a biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum, to be tested further. A pathologist can then examine the tissue with microscopes to determine whether it has cancerous cells.

The type of mesothelial cell involved, the malignant or benign nature of these cells as well as the location the cancer, its type and the stage of the tumor, are used to categorize the disease. Certain mesothelioma types have greater risk of spreading or metastasizing and it's crucial to establish a clear diagnosis so doctors can treat it before it becomes out of control.

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

Treatment

A diagnosis of mesothelioma can be frightening. It is important to remember, however, that cancer can be treated, particularly in its early stages. Many patients with mesothelioma live with the disease for a long time without expanding.

Exposure to asbestos may cause mesothelioma in many ways. asbestos legal fibres, too small to be felt or observed by naked eyes are able to become airborne and irritate the lining of the lung (pleura). Over time, the irritation causes the formation of scar tissue, which causes changes in the structure of cells that eventually develop into tumors.

The pleura surrounds the lungs and heart and the abdomen. Mesothelium consists of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to become scarred. In time, these changes can lead to the development of malignant mesothelioma tumors.

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

If imaging scans reveal an underlying mass in the lungs or stomach, a doctor will order biopsies. During the procedure, doctors will remove small amounts of the fluid or tumor for laboratory tests. The results can confirm the diagnosis of mesothelioma and help determine the most effective treatment plan.

There are several types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these methods. Patients can also benefit by participating in a clinical study of new mesothelioma treatment. To learn more, patients should consult mesothelioma experts who have expertise in treating the condition.
