Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the lung's outer lining (pleura). It is the most common mesothelioma that accounts for up 70% to 79% of diagnosed cases. People with this condition experience pain in the chest and breathlessness and may experience an ache or heaviness in the chest.

Exposure to asbestos, a family of minerals made of microscopic fibers, usually causes this type of cancer. Once inhaled, these fibers cling to the lung and cause irritation that causes scarring and DNA mutations. Pleura covers both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Some patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this cancer have a past that includes asbestos exposure at work. The most prevalent jobs that put people at risk of pleural mesothelioma include manufacturing, construction and shipbuilding. Individuals who have been in the military could be at an especially high risk due to the frequent asbestos lawsuit use in Navy vessels and bunkers used by the army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system for pleural adenocarcinoma. The stage a patient is in when they are diagnosed will aid their doctor in determining the best treatment plan for them. For instance, patients who have mesothelioma that is pleural in stage three or four have a poorer prognosis than those with lower stages. Mesothelioma in stage four can be spread to the liver, heart, or diaphragm. This makes the cancer more difficult to treat and increase the chances of complications for patients.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum -- it is a membrane that lines the abdominal cavity and organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma is triggered by asbestos exposure. Only 300-500 cases are diagnosed annually which is lower than pleural asbestosis.

As with pleural asbestosis, symptoms can take a long time to show. Patients generally experience abdominal pain, and may have a mass in their abdomen. Symptoms of this type of mesothelioma could also include nausea as well as weight loss and fever. Many of these symptoms could be misinterpreted as gastrointestinal issues which can lead to a false diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. Imaging tests like X-rays or CT scans can be used to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer that are not visible on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They also offer treatments. The stage of the disease is determined based on the type of cells and whether or not the cancer has spread to other regions of the body.

The most important risk factor for mesothelioma is asbestos exposure. People who have worked in jobs that involve asbestos, like plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if an individual does not work in any of these areas however, they may be exposed to asbestos to asbestos through family members and other sources. Anyone who believes they're at risk should speak with an expert. A mesothelioma specialist can assist those who have a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma which accounts for as much as 80 percent of all cases. Exposure to asbestos can occur through work, military service or by living with a person who works with asbestos or has previously done the same. When exposed to asbestos, particles can be breathed into the abdomen and lungs. These irritate the linings and cause cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely to get mesothelioma than people younger or more senior. It is because mesothelioma generally occurs between 20 and 60 years after the initial exposure before the first signs of cancer appear. It is important to keep in mind, too, that mesothelioma may occur in people who have been exposed to asbestos without having directly worked with it. This is called secondary or indirect exposure to asbestos, and it is just as harmful as direct exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more susceptible to asbestos lawyer. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. It is also important to remember that mesothelioma occurs more frequently for men than women. This is due to men being more likely to be exposed to asbestos and endure a a longer period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to be exposed to asbestos and don't typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms can be similar to other diseases. Due to this, patients are sometimes mistakenly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical history, including asbestos exposure. Doctors may also request an CT scan or chest X-ray to check for lumps, abnormalities, and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, that uses magnets and radio waves in order to produce a series of precise images of the insides of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. In a surgical biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum, to be examined further. A pathologist will then look at the tissue under a magnifying glass to determine if it contains cancerous cell.

The type of mesothelial cells involved, the malignant or benign nature of those cells as well as the location, type and stage of the cancer are used to categorize the disease. Some types of mesothelioma have an increased chance of metastasizing or spreading and it's crucial to get a definitive diagnosis to ensure that the doctors can treat it prior to it becoming out of control.

Doctors may also conduct tests in the laboratory on tumors to determine particular proteins, genes and other factors which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. However, it's important to remember that the cancer is treatable, especially in its initial stages. A lot of people suffering from mesothelioma be afflicted for a long time without spreading.

Exposure to asbestos settlement can trigger mesothelioma via various mechanisms. asbestos case; More Help, particles, which are too small to see or feel by the naked eye can become airborne and irritate the lining of the lungs (pleura). In time, the irritation causes the formation of scar tissue, which can cause changes in the structure of cells which eventually lead to tumors.

The Pleura is a protective layer 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.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all symptoms of the pleural mesothelioma. In rare cases cancer can spread to the tissues around the reproductive organs as well as the heart.

A doctor will request biopsy if scans show the possibility of a tumor in the lungs or stomach. During the procedure doctors remove some of the fluid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment plan.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these treatments. Enrolling in clinical trials of mesothelioma treatments that are new could be beneficial for patients. Patients can learn more by consulting a mesothelioma expert who has treated mesothelioma.
