Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in thin, long fibres. People who are regularly exposed to asbestos may develop lung diseases such as mesothelioma.

The symptoms of these diseases might not be evident for a long time after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma occurs in the outer lung lining, or pleura. It is the most frequent mesothelioma type and is responsible for 70 to 79% of diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling of heavyness.

This type of cancer is usually caused by exposure to asbestos which is a collection of minerals made up of microscopic fibres. When inhaled, these fibers cling to the lungs and cause irritation that causes scarring and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs, so these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Some patients also experience coughing, difficulty breathing, or chest tightness. People who suffer from this cancer usually have an history of exposure to asbestos in the workplace. The most prevalent jobs that expose people to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. People who served in the military are at greater risk due to the widespread use of asbestos in Navy vessels and bunkers in 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 that a patient is at at diagnosis will help their doctor determine the best treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or four will suffer a more negative outlook than those in a lower stage. Mesothelioma in stage four can develop into the liver, heart, or diaphragm. This can make the cancer more difficult to treat and increase the chances of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lining of the lung it develops in the membrane that covers the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, with only about 300-500 cases diagnosed each year.

As with pleural mesothelioma symptoms can take years to show. Patients usually experience abdominal pain, and could also experience a mass in their abdomen. The symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms are similar to those of digestive problems, which can cause confusion in diagnosis.

Generally speaking, doctors can detect mesothelioma through an extensive health history and physical examination. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can detect tumors and other signs of cancer that aren't visible on X-rays.

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

Asbestos exposure is the main risk factor. People who have been in occupations that involve asbestos, like plumbing or manufacturing, electrical work, or construction, are at a higher risk of developing the disease. However, even if people aren't employed in these areas they may be exposed to asbestos through family members or other sources. For this reason, anyone who believes they could be at risk should speak to an experienced doctor. A mesothelioma specialist can assist those who have a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma accounting for up to 80 percent of cases. Exposure to asbestos can happen due to work, military service, or by living with a person who works with asbestos or used to do such. Asbestos particles are inhaled by those who are exposed to asbestos. These particles can cause irritation to the linings and cause cancerous cells to form in the mesothelium. After exposure to asbestos, mesothelioma may be diagnosed between 15 and 60 years.

Other risk factors include genetics, smoking and aging. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or more senior. This is because mesothelioma usually lasts between 20 and 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to remember that mesothelioma could develop in those who have been exposed to asbestos without having directly worked with it. This is known as indirect or secondary asbestos exposure and can be as dangerous as direct asbestos exposure.

Smoking can increase the likelihood of getting mesothelioma because it causes mesothelium damage and makes it more susceptible to Monroe Asbestos Law Firm. Mesothelioma is also aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is due to the fact that men are more likely to work with south sioux city asbestos attorney and have a longer period of exposure than women. Additionally, men are more likely to live with someone who has had asbestos exposure and bring stray asbestos fibers home on their clothes. Women are less likely to come into contact with asbestos and do not typically carry asbestos home on their clothes.

Diagnosis

It is difficult to recognize mesothelioma due to its symptoms being frequently similar to other illnesses. Because of this, victims are often mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform a physical exam and take note of the medical history of the patient which includes asbestos exposure. Doctors will also order an CT scan or chest X-ray to check for abnormalities, lumps and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels and magnetic resonance imaging, also known as MRI test that uses radio waves and magnets to create detailed images of the interior of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. A surgical biopsy is when doctors remove a small piece of tissue from the peritoneum or pleura to conduct further tests. A pathologist can then examine the tissue under microscopes to determine if it is contaminated with cancerous cells.

Mesothelioma is classified based on the type of mesothelial cells involved, whether the cells are malignant or benign and also the location of the tumor, the type, and the stage of the tumor. Certain mesothelioma types have a higher risk 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 can also run tests in the lab on a tumor to identify particular proteins, genes and other factors that can help them describe the characteristics of the cancer and determine a treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnosis can be terrifying. It is important to keep in mind that cancer can be treated, particularly in its initial stages. Many people with mesothelioma live for many years with the disease without it spreading to other areas of their body.

Exposure to asbestos can cause mesothelioma through various mechanisms. Asbestos fibers, which are small enough to not be felt or seen by naked eyes are able to become airborne, causing irritation to the lung's lining (pleura). Over time, the irritation causes the formation of scar tissue, which can cause changes in the cell structure that eventually develop into tumors.

The pleura is a protective covering that covers the abdomen, heart, and lungs. Mesothelium is composed of cells that react to asbestos and cause it to enflame and form scar tissue. As time passes, these changes result in the growth of malignant mesothelioma cancers.

The signs of pleural mesothelioma can include shortness of breath, chest pain or the accumulation of fluid on the lung (pleural effusion). In rare cases the cancer may be spread to the tissues around the heart and reproductive organs.

If scans of imaging reveal an underlying mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors will remove small amounts of the tumor or fluid for lab analysis. The results will confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are a variety of mesothelioma treatment, including surgery, chemotherapy and immunotherapy. Most doctors utilize the combination of these methods. Participating in clinical trials of mesothelioma treatments that are new could be beneficial for patients. To find out more, patients should speak to a mesothelioma specialist who has had experience treating the disease.
