Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that comes in thin, long fibres. People who are exposed to asbestos regularly are at risk of developing mesothelioma as well as other lung diseases.

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

Pleural Mesothelioma

Pleural mesothelioma occurs in the outer lung lining, or the pleura. It is the most frequent type of mesothelioma, making up between 70 and 79% of all diagnosed cases. The condition can cause chest pain, breath shortness, and a feeling of heaviness.

This type of cancer is usually caused by exposure to asbestos which is a collection of minerals that are composed of microscopic fibers. These fibers, when inhaled can cause irritation and DNA mutations. The pleura covers the chest cavity and lungs and therefore, these irritations could affect both the lungs and a person's heart. Mesothelioma symptoms are usually not apparent 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 have a past 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 served in the military are at a greater risk due to the widespread use of asbestos attorney in Navy vessels and bunkers in the Army.

The most common staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at when they are diagnosed will assist their doctor in determining the most effective treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis compared to those who are in a lower stage. Stage four mesothelioma is often spread to the diaphragm, the liver and/or a person's heart. This could make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum -- it is a membrane that lines the abdominal cavity as well as organs such as the intestines and liver. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. Only 300-500 cases are diagnosed annually this is less than the pleural asbestosis.

Like pleural mesothelioma, the symptoms can take years to show. Patients generally suffer from abdominal pain and may have a mass in their abdomen. The symptoms of this kind of mesothelioma may also include nausea or weight loss, as well as fever. Many of these symptoms could be misinterpreted as digestive issues which can lead to a false diagnosis.

Generally speaking, doctors can detect mesothelioma after an extensive health history and physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans 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 identify mesothelioma, and determine the stage. They can also suggest treatment options. The stage of the disease is determined based on the type of cell and whether or the cancer has spread to other parts of the body.

Asbestos exposure is the most important risk factor. People who have worked in professions that involve asbestos, such as plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. However, even if individuals aren't employed in these areas they may be exposed to asbestos through family members or through other sources. Anyone who believes they're at risk should speak with an expert. If they have a history of asbestos exposure, a mesothelioma specialist can assist them in learning more about the risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, which accounts for as much as 80 percent of cases. Exposure to asbestos can occur due to military service, work or living with people who have worked with asbestos. Asbestos particles can be breathed in by those who are exposed to it. The particles cause irritation to the linings, causing cancerous cells to form 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 develop mesothelioma than those who are younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is also important to note that mesothelioma is a possibility in people who have been exposed to asbestos but did not engage directly with it. This is known as secondary or indirect asbestos attorney exposure. It can be as dangerous as direct asbestos exposure.

Smoking increases a person's chances of getting mesothelioma because it damages the mesothelium and makes it more susceptible to asbestos. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for a longer time and to work with it. Men are also more likely to have lived with someone who worked with asbestos, and to carry asbestos compensation fibers on their clothing. Women are less likely to come into exposure to asbestos and do not typically carry asbestos around on their clothes.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being frequently similar to other illnesses. This can result in patients being wrongly diagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient, including asbestos case (please click the following webpage) exposure. Doctors will also order an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of asbestos compensation exposure. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance image, or MRI test, which makes use of radio waves and magnets to create a series detailed images of inside the body. A surgical biopsy is another method for doctors to identify mesothelioma. When a biopsy is performed, doctors remove a tiny part of tissue from the pleura or the peritoneum to be further examined. A pathologist then examines the tissue under a magnifying lens to determine whether it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether those cells are benign or malignant, and the location, type, and stage of the cancer. Certain types of mesothelioma may be more likely to develop metastasis or spread which is why it is crucial to get a definite diagnosis so that doctors can treat the disease before it goes out of control.

Doctors may also conduct laboratory tests on tumors to identify specific genes, proteins or other elements that can aid in describing cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be terrifying. It is important to remember, however, that cancer can be treated, particularly in its early stages. A lot of people suffering from mesothelioma be afflicted for many years without it spreading.

Asbestos exposure can cause mesothelioma by many mechanisms. asbestos settlement particles, which are too small to detect or feel with the naked eye, can become airborne and cause irritation to the lining of the lungs (pleura). As time passes the irritation causes the formation of scar tissue, which eventually lead to tumors.

The Pleura is a covering that protects the lungs, heart and abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They cause inflammation of the tissue and cause it to become scarred. These changes can lead to malignant mesothelioma tumours.

The signs of pleural mesothelioma can include breathlessness and chest pain, or a buildup of fluid in the lungs (pleural effusion). In rare instances the cancer may spread to the tissues surrounding 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 take small amounts of the fluid or tumor for laboratory tests. The results will confirm a mesothelioma diagnosis, and determine the most effective treatment plan.

There are many types of treatment for mesothelioma, including surgery and chemotherapy. Most doctors utilize the combination of these treatments. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatment. Patients can learn more about the trials by consulting a mesothelioma expert who has treated mesothelioma.
