Mesothelioma and Asbestos

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

It could take a long time for symptoms to show up after asbestos settlement exposure. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, or pleura. It is the most frequent mesothelioma type, accounting for up 70 to 79% of all diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling heaviness.

Exposure to asbestos, a group of minerals composed of microscopic fibers, usually causes this kind of cancer. The fibers, when inhaled can cause irritation and DNA mutations. The pleura covers the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may have coughing problems, trouble breathing or chest tightness. Patients with this type of cancer have a history that includes asbestos exposure at work. The most prevalent jobs that expose people to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who have served in the military may be at a higher risk because of the extensive asbestos usage in Navy vessels and bunkers used by the army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has at diagnosis will help their doctor determine the most appropriate treatment plan for them. For instance, patients suffering from a pleural mesothelioma in stage three or four have a less favorable prognosis than patients with lower stages. Stage four mesothelioma can spread to the heart, liver or diaphragm. This makes the cancer more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to 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 liver and intestines. Similar to pleural mesothelioma, exposure to asbestos case (learn more about nongfag.go.th) is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed annually, which is less than the pleural asbestosis.

As with pleural asbestosis symptoms can take several years to manifest. Most patients experience abdominal pain and an abdominal mass. The symptoms of this type of mesothelioma could also include nausea or weight loss, as well as fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues, leading to a false diagnosis.

Doctors can identify mesothelioma by looking over the medical history of the patient and performing a physical exam. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can show cancerous tumors or other indications of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma and establish the stage. They can also recommend treatment options. The staging is determined by the type of cells and whether or the cancer has spread to other parts of the body.

The most significant risk factor for mesothelioma is exposure to asbestos legal. People who have been in occupations which require asbestos, such as plumbing, manufacturing, electrical work or construction, are at a higher risk of developing the disease. However, even if people do not work in these fields they could be exposed to asbestos through family members or other sources. Therefore, anyone who is concerned that they might be at risk should talk to an expert. If they have any 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 the main risk factor for mesothelioma, accounting for up to 80 percent of all cases. Exposure to asbestos can happen due to military service, work, or living with someone who used to work with asbestos law. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. They can cause irritation to the linings of the abdomen and trigger cancerous cells to grow 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 age. The people in their 40s or 50s are at greater risk of developing mesothelioma as compared to people who are younger or more. Mesothelioma can take between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is also important to note that mesothelioma may develop in people who were exposed to asbestos compensation but didn't engage directly with it. This is referred to as indirect or secondary exposure to asbestos and it can be just as dangerous as direct exposure.

Smoking increases the risk of developing mesothelioma since it damages the mesothelium and makes it more vulnerable to asbestos. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos compensation for a longer time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come into contact with asbestos and do not typically carry asbestos around on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are frequently similar to other illnesses. This is why patients are sometimes mistakenly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background, including asbestos exposure. Doctors may also order an X-ray of the chest or CT scan to detect lumps or other abnormalities, as well as evidence of past asbestos exposure such as pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, that uses radio waves and magnets in order to create a series detailed images of the insides of the body. A surgical biopsy is another method for doctors to identify mesothelioma. When a biopsy is performed doctors take a tiny part of tissue from the pleura or the peritoneum to be examined further. A pathologist can then examine the tissue using a magnifying lens to determine if it contains cancerous cell.

The mesothelial type involved and the benign or malignant nature of those cells as well as the location and stage of the tumour, are used to categorize the disease. Certain types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to establish a definitive diagnosis so doctors can treat the disease before it becomes out of control.

Doctors may also conduct tests in the lab on tumors to identify specific proteins, genes, or other factors which can aid in describing the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to keep in mind, however, that cancer can be treated, particularly in its early stages. Many mesothelioma patients live for many years without the disease spreading to other areas of their body.

Exposure to asbestos may cause mesothelioma in a number of ways. Asbestos fibers, which are too small to see or feel through the naked eye, can become airborne and cause irritation to the lining of the lungs (pleura). In time irritation leads to formation of scar tissue, which can cause changes in the cell structure that can eventually grow into tumors.

The pleura surrounds the heart and lungs and the abdomen. Mesothelium consists of cells that react to asbestos which causes it to become inflamed and form scar tissue. These changes can eventually result in malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness, chest pain or a buildup of fluid in the lungs (pleural effusion). In rare instances the cancer may be spread to the tissues around the heart and reproductive organs.

If imaging scans show an area of concern in the stomach or lungs the doctor will request a biopsies. During the procedure, doctors take tiny amounts of tumor or fluid for lab analysis. The results can confirm a mesothelioma diagnosis, and provide the most effective treatment plan.

There are several types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors use combinations of these treatments. Patients could also benefit from enrolling in a clinical trial of new mesothelioma therapies. To learn more, patients should consult a mesothelioma specialist who has had experience treating the disease.
