Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining or pleura. It is the most common type of mesothelioma, making up between 70 and 79% of all diagnosed cases. Patients suffering from this condition suffer from chest pain and breathlessness, and they may feel a sensation of heaviness in the chest.

Exposure to asbestos, a family of minerals comprised of microscopic fibers causes this kind of cancer. Once inhaled, these fibers are absorbed into the lung and cause irritation which causes scarring and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Some patients also experience coughing, difficulty breathing or chest tightness. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Manufacturing, construction and shipbuilding are the most prevalent jobs that put people at high risk of developing pleural mesothelioma. 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 commonly used staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage the 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 stage four will have a worse prognosis compared to those in a lower stage. Stage four mesothelioma often spreads to the liver, diaphragm or even the heart of a patient. This can make the cancer more difficult to treat, and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum - a membrane that lines the abdominal cavity and organs such as the liver and intestines. Similar to pleural mesothelioma mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed annually which is lower than pleural asbestosis.

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

Generally speaking, doctors can detect mesothelioma after a thorough health history and physical examination. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can reveal tumors and 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 and recommend treatment options. The staging is determined by the type of cells and whether or not the tumor has spread to other areas 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 areas they could be exposed to asbestos through family members or other sources. Therefore, anyone who believes they could be at risk should talk to an expert. A mesothelioma specialist can help those who have had a history with asbestos case to learn 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 happen through military service, work, or living with those who worked with asbestos. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings and can cause cancerous cells to develop in the mesothelium. Following exposure to asbestos mesothelioma can be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics and the advancing age. People in their 40s or 50s are at a higher chance of developing mesothelioma to those younger or older. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind that mesothelioma can develop in those who have been exposed to asbestos without having worked with it directly. This is known as indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be caused by certain diseases, such as asbestosis and pneumonia. It is also important to note that mesothelioma is more prevalent in males than females. Men are more likely than women to have been exposed to asbestos for a longer period of time and to work with asbestos for longer periods of time. Men are also more likely to have lived with someone who been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to be exposed to asbestos and they are less likely to bring asbestos compensation home on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms are often similar to other conditions. This could lead to patients being incorrectly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient which includes asbestos - simply click the up coming post, exposure. Doctors will also order 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 imaging, 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 yet another way for doctors to diagnose mesothelioma. When a biopsy is performed doctors will remove a small piece of tissue from the pleura or the peritoneum to be further examined. A pathologist can then examine the tissue under microscopes to determine if it is contaminated with cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether these cells are malignant or benign, and the location of the tumor, the type, and the stage of the cancer. Some types of mesothelioma have an increased risk of spreading or metastasizing, so it's important to establish a clear diagnosis so that doctors can treat it before it becomes out of control.

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

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to remember that cancer can be treated, particularly in its initial stages. A lot of people suffering from mesothelioma be afflicted for a long time, without expanding.

Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibers that are small enough to not be felt or viewed by naked eyes, can become airborne and irritate the lining of the lung (pleura). As time passes the irritation can lead to the formation of scar tissues and eventually tumors.

The pleura is the area that surrounds the lungs and heart and also the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. In time, these changes can cause the development of malignant mesothelioma cancers.

The symptoms of pleural mesothelioma are shortness of breath, chest pain or an accumulation of fluid on the lungs (pleural effusion). In rare instances, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal an area of concern in the lungs or stomach the doctor will request biopsies. In the course of the procedure, doctors remove a small amount of liquid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma and provide the best treatment option.

There are many types of treatment for mesothelioma, including chemotherapy and surgery. Most doctors rely on a combination of these methods. Participating in clinical trials for mesothelioma treatments may be beneficial to patients. To find out more, patients should consult mesothelioma experts who have had experience treating the disease.
