Mesothelioma and Asbestos

Asbestos is a mineral that occurs naturally in the form of long, thin fibers. People who are exposed to asbestos risk developing lung diseases, such as mesothelioma.

It can take years for symptoms to show up after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, also known as pleura. It is the most frequent type of mesothelioma, making up between 70 and 79% of diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling of heavyness.

This type of cancer is typically caused by exposure to asbestos, which is a collection of minerals that are composed of microscopic fibers. The fibers, when inhaled can cause irritation and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs, so these irritations can affect both the lungs and the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 year after exposure.

The most frequent symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also experience coughing, difficulty breathing or chest tightness. Patients with this cancer have a past that includes asbestos exposure at work. The most common jobs that expose people to the risk of developing pleural cancer are manufacturing, construction and shipbuilding. People who have served in the military could be at a higher risk due to the widespread asbestos usage in Navy vessels and bunkers used by the army.

The most popular staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that the patient is in at the time of diagnosis can help determine the treatment plan they should follow. For instance, patients who have mesothelioma that is pleural in stage three or four have a poorer prognosis than patients with lower stages. Stage four mesothelioma may develop into the liver, heart or diaphragm. This could make the cancer more difficult to treat and increase the chances of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that develops in the lung lining, peritoneal mesothelioma forms in the peritoneum - a membrane that lines the abdominal cavity and organs like the intestines and liver. As with pleural mesothelioma asbestos lawyer exposure is the primary cause of peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to manifest. Patients generally have abdominal pain, and could also experience a mass in their abdomen. The symptoms of this kind of mesothelioma may also include nausea, weight loss and fever. Many of these symptoms can be misinterpreted as digestive issues which can lead to a mistaken diagnosis.

The doctors can detect mesothelioma through examining the patient's medical history 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 signs of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The stage is determined by the type of cell and whether the tumor has spread.

Asbestos exposure is the most important risk factor. People who have worked in jobs which require asbestos, like plumbing or manufacturing, electrical work, or construction, are at a higher risk of developing the disease. Even if they aren't employed in these areas they could be exposed to asbestos case through relatives or other sources. This is why anyone who believes they could be at risk should speak 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 their risk.

Risk Factors

Asbestos exposure is the main mesothelioma risk factor, making up 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 such. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. The particles cause irritation to the linings of the lungs, causing cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and age. People in their 40s or 50s are at greater risk of developing mesothelioma as compared to those younger or older. It is because mesothelioma generally occurs between 20 and 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to note that mesothelioma may develop in people who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as secondary or indirect exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium and makes it more vulnerable to asbestos. Furthermore, mesothelioma is caused by certain illnesses, such as pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for a longer period of time and work with it. Men are also more likely to have lived with someone who had worked with asbestos and to have asbestos fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos home on their clothing.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms can be similar to other diseases. This could lead to patients being wrongly diagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical history including asbestos case; please click the following website, exposure. Doctors may also order a chest X-ray or CT scan to check for lumps and other abnormalities, as well as evidence of previous asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the formation of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels, and a magnetic resonance imaging, or MRI, test, which uses magnets and radio waves to make a series of detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is to perform an operation called a biopsy. In a surgical biopsy doctors remove a small piece of tissue from the pleura or peritoneum for further testing. A pathologist then examines the tissue with a magnifying lens to determine if it is a cancerous cells.

Mesothelioma is classified based on the mesothelial type involved, whether the cells are malignant or benign and the location of the tumor, its type, and the stage of the tumor. Certain mesothelioma types have greater chance of metastasizing or spreading and it's crucial to determine the type of mesothelioma so doctors can treat it before it becomes out of control.

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

Treatment

A mesothelioma diagnose can be terrifying. It is crucial to remember that cancer can be treated especially at 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 by the naked eye 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 cell structure that eventually develop into tumors.

The pleura surrounds the lungs and heart, as well as the abdomen. Mesothelium consists of cells that react to asbestos which causes it to become inflamed and create scar tissue. Overtime, these changes cause the development of malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include shortness of breath, chest pain or the accumulation of fluid in the lung (pleural effusion). In rare instances, cancer can spread into the tissues that surround the reproductive organs and the heart.

A doctor will request a biopsy if imaging scans show a potential lung tumor or stomach. The procedure involves the removal of small amounts of liquid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and determine the best treatment plan.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize an amalgamation of these techniques. Patients may also benefit from enrolling in a clinical trial of new mesothelioma therapies. Patients can learn more about the trials by consulting a mesothelioma expert who has treated the disease.
