Mesothelioma and Asbestos

Asbestos, a mineral that naturally forms in the form of long, thin fibers. People who are exposed to asbestos regularly are at risk of developing mesothelioma as well as other types of lung diseases.

It could take a long time for symptoms to show up after asbestos compensation exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that affects the outer lung liner (pleura). It is the most common type of mesothelioma, making 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 type of cancer. When inhaled, these fibers cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Some patients may also experience chest tightness, coughing or difficulty breathing. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Manufacturing, construction and shipbuilding are among the most prevalent occupations that put people at high chance of developing pleural mesothelioma. Individuals who have been in the military are at an especially high risk because of the extensive use of asbestos claim in Navy vessels and bunkers used by the army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most popular staging system used for pleural adenocarcinoma. The stage a patient is in at the moment of diagnosis will determine what treatment plan they should follow. Patients who have pleural mesothelioma which is in stage three or four will have a less favorable prognosis compared to those who are in a lower stage. Stage four mesothelioma often spreads to the diaphragm, the liver or even the heart of a patient. This makes it more difficult to treat and increases the risk of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum -- an elongated membrane that covers the abdominal cavity and organs like the intestines and the liver. As with pleural mesothelioma exposure to asbestos is the reason for peritoneal msothelioma. The disease is less common than pleural mesothelioma, and only about 300-500 cases diagnosed each year.

As with pleural asbestosis symptoms can take years to manifest. Patients generally experience abdominal pain, and may have a mass in their abdomen. The symptoms of this type of mesothelioma can also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to those experienced by digestive problems, which can lead to incorrect diagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and performing a physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can show cancerous tumors or other signs of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage of the disease is determined based on the type of cell and whether or whether the tumor has spread to other parts of the body.

Asbestos exposure is the most important risk factor. People who have worked in professions which require asbestos, such as plumbing manufacturing, electrical work or construction, are at increased risk of developing the disease. Even if they aren't employed in these fields, they can still be exposed to asbestos through family members or other sources. For this reason, anyone who believes they could be at risk should talk to a doctor. If they have an history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in finding out more about their risk.

Risk Factors

Asbestos Case; Www.Landrich.Co.Kr, is the primary risk factor for mesothelioma. It accounts for as much as the 80% of cases. Exposure to asbestos lawyer may occur due to military service, work, or living with someone who used to work with asbestos. When exposed to asbestos, particles are able to be inhaled into lungs and abdomen. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. Following exposure to asbestos, mesothelioma may be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics and age. The people in their 40s or 50s are more at chance of developing mesothelioma to those who are younger or older. This is because mesothelioma usually lasts between 20 and 60 years from the first exposure to asbestos before cancer symptoms appear. It is also important to know that mesothelioma can develop in people who were exposed to asbestos, but did not work with it directly. This is called secondary or indirect exposure to asbestos, and it can be just as dangerous as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It can also make it more vulnerable. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is due to men being more likely to work with asbestos and experience a more exposure than women. Men are also more likely to have lived with someone who been exposed to asbestos, and to carry asbestos fibers on their clothing. Women are less likely to come into contact with asbestos and do not typically carry asbestos on their clothes.

Diagnosis

It is difficult to identify mesothelioma since its symptoms are often similar to other diseases. This is why patients are often misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history which includes asbestos exposure. Doctors will also recommend an CT scan or chest X-ray to look for lumps, abnormalities and evidence of exposure to asbestos. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, which uses magnets and radio waves in order to create a series of detailed images of the insides of the body. Another way for doctors to detect mesothelioma is through the procedure of a surgical biopsy. In a surgical biopsy doctors take a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist is then able to examine the tissue under microscopes to determine if it is contaminated with cancerous cells.

The mesothelial type involved, the malignant or benign nature of the cells as well as the location the cancer, its type and the stage of the tumor, are used to classify the disease. Certain mesothelioma types have a higher risk of metastasizing or spreading and it's crucial to get a definitive diagnosis so that doctors can treat it before it gets out-of-control.

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

Treatment

A mesothelioma diagnosis can be terrifying. It is important to keep in mind, however, that cancer can be treated, particularly in its early stages. Many patients with mesothelioma endure the disease for many years without it expanding.

Exposure to asbestos may cause mesothelioma in many ways. Asbestos particles, which are too small to be able to see or feel with the naked eye, can be airborne and cause irritation to the lung's lining (pleura). Over time the irritation causes the formation of scar tissues that eventually result in tumors.

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

Breathing problems, chest discomfort or fluid buildup on the lungs are all indications of the pleural Msothelioma. In rare cases, the cancer can be spread to the tissues around the heart and reproductive organs.

A doctor will order a biopsy if imaging scans reveal a possible lung tumor or stomach. The procedure involves the removal of some of the fluid or tumor to allow for tests in the laboratory. The results will confirm the diagnosis of mesothelioma and indicate the most effective treatment plan.

There are a variety of mesothelioma treatment, which include chemotherapy, surgery, and immunotherapy. Most doctors rely on the combination of these methods. Patients may also benefit from enrolling in a clinical trial of new mesothelioma treatment. To learn more about the trials, patients should consult a mesothelioma specialist who has expertise in treating the condition.
