Mesothelioma and Asbestos

asbestos litigation is a natural mineral that is made up of thin, long fibres. People who are exposed to asbestos regularly risk developing mesothelioma and other lung diseases.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung lining (pleura). It is the most prevalent mesothelioma form and accounts for 70% to 79% of all diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of heaviness.

Exposure to asbestos, a class of minerals composed of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled, cause irritation and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, and so irritations can also affect the 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. Some patients may also experience chest tightness, coughing or difficulty breathing. Patients with this cancer have a past that includes asbestos exposure at work. The most prevalent jobs that expose workers to the risk of developing pleural mesothelioma are construction, manufacturing and shipbuilding. People who served in the military are at a greater risk due the extensive use asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used for the pleural cancer. The stage that a patient is at when they are diagnosed will aid 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 patients with a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver or even a person's heart. This makes it more difficult to treat and raises the likelihood of complications for patients.

Peritoneal Mesothelioma

Contrary to pleural cancer that develops in the lung's lining it develops in a membrane that covers the abdominal cavity, which includes organs such as the intestines and the liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. It is estimated that only 300-500 cases are diagnosed annually this is less than pleural asbestosis.

As with pleural mesothelioma symptoms can take years to show. Most patients suffer from abdominal pain and abdominal swelling. This kind of mesothelioma can cause nausea, weight loss and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can result in incorrect diagnosis.

Doctors can detect mesothelioma by looking over the medical history of the patient and performing a physical exam. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can detect tumors and other cancer signs that are not evident on X-rays.

These test results enable doctors to diagnose mesothelioma and establish the stage. They can also recommend treatment options. The stage is determined by the type of cell and whether the cancer has spread.

Asbestos exposure is the biggest risk factor. People who have worked in asbestos-related jobs, such as plumbing or electrical work, or in manufacturing and construction are more likely to contract the disease. Even if they aren't employed in these areas they could be exposed to asbestos through family members or through other sources. Anyone who thinks they are at risk should talk to a doctor. If they have an history of exposure to asbestos and mesothelioma is a concern, a specialist will help them find out more about the risk.

Risk Factors

Asbestos exposure is a major mesothelioma risk factor, accounting for up to 80 percent of all cases. Exposure to asbestos can happen as a result of work, military service, or by living with someone who is exposed to asbestos or used to do such. Asbestos particles can be breathed in by people who are exposed to asbestos. These particles can cause irritation to the linings, causing cancerous cells to grow in the mesothelium. Following exposure to asbestos, mesothelioma may develop between 15 and 60 years old.

Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely to get mesothelioma than people younger or older. This is because mesothelioma usually occurs between 20 and 60 years after the initial exposure to asbestos before symptoms of cancer begin to manifest. It is also important to note that mesothelioma can develop in people who were exposed to asbestos but didn't deal with it directly. This is referred to as secondary or indirect asbestos exposure and can be as dangerous as direct asbestos exposure.

Smoking increases a person's chances of getting mesothelioma because it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma is also aggravated by certain illnesses such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is because men are more likely to work with asbestos case and experience a an extended period of exposure than women. Men are also more likely to have lived with someone who had been exposed to asbestos law, and to have asbestos fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos legal around on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms are often similar to other conditions. This can lead to victims being incorrectly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take down a patient's medical history, including asbestos exposure. Doctors can also order an X-ray chest or CT scan to detect lumps or other abnormalities, as well as evidence of past asbestos law exposure such as plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test that uses magnets and radio waves to make a series of precise images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform the procedure of a surgical biopsy. In a surgical biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum to be further examined. A pathologist can then examine the tissue using a magnifying lens to determine if it is a cancerous cells.

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

Doctors may also conduct tests in the laboratory 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 known as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. It is important to keep in mind, however, that cancer can be treated particularly in its early stages. Many mesothelioma patients live for a long time with the disease, without spreading to other organs of their body.

Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibers that are tiny enough to be felt or observed by naked eyes, can become airborne and irritate the lung's lining (pleura). In time irritation can lead to formation of scar tissue which causes changes in the structure of cells which eventually lead to tumors.

The pleura surrounds the heart and lungs and also the abdomen. Mesothelium consists of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to become scarred. 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 indications of the pleural mesothelioma. In rare cases cancer can spread to the tissues that surround the reproductive organs as well as the heart.

A doctor will request a biopsy if imaging scans show a potential tumor in the lungs or stomach. During the procedure, doctors take small amounts of the fluid or tumor for laboratory analysis. The results will confirm the diagnosis of mesothelioma and provide the most effective treatment plan.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these methods. Patients may also benefit from enrolling in a clinical trial of new mesothelioma treatment. Patients can learn more by speaking with a mesothelioma doctor who has treated the disease.
