Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in long, thin fibres. Workers who are regularly exposed to asbestos risk developing lung diseases, such as mesothelioma.

It could take a long time before symptoms begin to manifest after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that occurs in the lung's outer liner (pleura). It is the most prevalent mesothelioma that accounts for up 70 to 79% of all diagnosed cases. Patients with this disease experience pain in the chest and breath shortness and may also feel an ache or heaviness in the chest.

Exposure to asbestos, a group of minerals composed of microscopic fibers 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 are usually not apparent until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and breath shortness. Patients may also suffer from chest tightness and coughing, or breathing difficulties. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of pleural mesothelioma include manufacturing, construction and shipbuilding. People who were in the military are at a greater risk due the frequent use of asbestos in Navy vessels and bunkers in the Army.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that the patient is in at the moment of diagnosis will determine the treatment plan they should receive. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable outlook than those in a less advanced stage. Stage four mesothelioma can spread to the liver, heart, or diaphragm. This makes it more difficult to treat and increases 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, a membrane that lines the abdominal cavity as well as organs such as the liver and intestines. As with pleural mesothelioma asbestos exposure is the cause of peritoneal mesothelioma. The disease is less common than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take a long time to manifest. Most patients are afflicted with abdominal pain as well as an abdominal mass. The symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can cause confusion in diagnosis.

Generally speaking, doctors can detect mesothelioma after an extensive health history and physical exam. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors as well as other signs of cancer which aren't evident on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatments. 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 asbestos-related jobs, such as electrical or plumbing work, or in construction, manufacturing and manufacturing, are more likely to contract the disease. Even if an individual isn't employed in any of these areas they could be exposed to asbestos through family members or other sources. Anyone who suspects that they may be at risk should speak with a doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can assist them in learning more about the risk.

Risk Factors

Asbestos case exposure is a major risk factor for mesothelioma, which accounts for as much as 80 percent of all cases. Exposure to asbestos may occur as a result of work, military service or by living with a person who works with asbestos or was previously exposed to doing so. Asbestos particles can be inhaled by people who are exposed to it. The particles cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or more senior. This is because mesothelioma usually takes 20 to 60 years after the initial time of exposure before symptoms of cancer begin to manifest. It is important to remember that mesothelioma is a possibility in people who have been exposed to asbestos but didn't engage directly with it. This is referred to as indirect or secondary asbestos exposure, and is as hazardous as direct asbestos exposure.

Smoking increases the chance of mesothelioma developing, because it damages the mesothelium. It can also make it more vulnerable. Additionally, mesothelioma can be exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to note that mesothelioma occurs more frequently in males than females. This is because men are more likely to be exposed to asbestos and endure a a longer period of exposure than women. Men are also more likely to live with someone who has was exposed to asbestos and bring stray asbestos lawsuit fibers home on their clothes. Women are less likely to be in contact with asbestos, and they don't usually carry asbestos compensation on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms can be similar to other diseases. This is why patients are sometimes misdiagnosed.

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

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart, and a magnetic resonance imaging, or MRI, test, which makes use of magnets and radio waves to create detailed images of the interior of the body. A surgical biopsy is another method for doctors to identify mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist can then look at the tissue under microscopes to determine whether it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cell involved, whether the cells are malignant or benign, and the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma are at greater chance of metastasizing or spreading, so it's important to establish a clear diagnosis to ensure that the doctors can treat it prior to it becoming out-of-control.

Doctors can also run tests in the laboratory on a tumor to find particular proteins, genes or other elements which can help them identify the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A mesothelioma diagnose can be terrifying. It is important to keep in mind, however, that cancer can be treated, particularly in its initial stages. Many patients with mesothelioma endure the disease for a long time without spreading.

asbestos settlement exposure can cause mesothelioma through various mechanisms. Asbestos fibers, which are too small to detect or feel by the naked eye can be airborne and cause irritation to the lining of the lungs (pleura). In time, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura is the area that surrounds the lungs and heart, as well as the abdomen. Mesothelium consists of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to become scarred. Overtime, these changes result in the growth of malignant mesothelioma tumors.

A shortness of breath, chest pain or fluid accumulation on the lungs are all signs of the pleural msothelioma. In rare instances the cancer may grow to the tissues surrounding the heart and reproductive organs.

A doctor will request a biopsy if imaging scans reveal a possible lung tumor or stomach. During the procedure, doctors take tiny amounts of fluid or tumor for laboratory tests. The results will confirm a mesothelioma diagnosis, and determine the best treatment option.

There are a variety of treatment for mesothelioma including chemotherapy and surgery. Most doctors utilize the combination of these methods. Participating in clinical trials of mesothelioma treatments that are new could be beneficial for patients. Patients can find out more by consulting a mesothelioma specialist who has treated mesothelioma.
