It s The Mesothelioma And Asbestos Case Study You ll Never Forget

Mesothelioma and Asbestos

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

It may take decades before symptoms begin to manifest after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining also known as the pleura. It is the most frequent type of mesothelioma, making up 70% to 79% of diagnosed cases. This condition causes chest pain, breath shortness, and a feeling of heaviness.

This type of cancer is typically caused by exposure to asbestos, which is a grouping of minerals that are comprised of microscopic fibres. Once inhaled, the fibers stick inside the lung and cause irritation which results in scarring and DNA mutations. Pleura surrounds both the chest cavity and the lungs, so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

The most common symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Some patients may also feel tightness in their chest, coughing or difficulty breathing. Patients with this type of cancer typically have a history of exposure to asbestos claim in the workplace. The most common jobs that expose workers to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who were in the military are at higher risk due to the extensive use asbestos in Navy vessels and bunkers in the Army.

The most common staging system for pleural mysothelioma has been 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 will receive. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable prognosis compared to those in a less advanced stage. Stage four mesothelioma is often spread to the diaphragm, the liver or even the heart of a patient. This makes it more difficult to treat and raises the risk of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum, an elongated membrane that covers the abdominal cavity as well as organs such as the liver and intestines. Similar to pleural mesothelioma, asbestos exposure is the reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take a long time to show. Patients generally suffer from abdominal pain and may have a mass in their abdomen. Symptoms of this type of mesothelioma may also include nausea, weight loss and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues which can lead to a false diagnosis.

Generally speaking, doctors can detect mesothelioma through a thorough health history and physical examination. They can also use imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can detect tumors and other signs of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and establish the stage. They can also recommend treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have been in occupations which require asbestos, such as plumbing or manufacturing, electrical work or construction, are at greater risk of developing the disease. However, even if individuals do not work in these fields they could be exposed to asbestos through relatives or other sources. Anyone who believes they're at risk should speak with an expert. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about their risk.

Risk Factors

asbestos litigation exposure is the main risk factor for mesothelioma which accounts for as much as 80 percent of all cases. Exposure to asbestos can occur due to military service, work or living with someone who used to work with asbestos litigation. When exposed to asbestos, small particles are able to be inhaled into lungs and abdomen. The particles cause irritation to the linings, causing cancerous cells to develop in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more at chance of developing mesothelioma to those who are younger or older. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to remember, too, that mesothelioma may occur in those who have been exposed to asbestos without having worked with it directly. This is known as indirect or secondary asbestos case exposure and can be just as harmful as direct asbestos exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more susceptible. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos for longer periods of time and work with asbestos for longer durations and to work with it. Additionally, men are more likely to live with someone who was exposed to asbestos and bring asbestos fibers from their workplace on their clothing. Women are less likely to be exposed to asbestos and don't typically bring asbestos home on their clothing.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms can be similar to other conditions. This can lead to victims being misdiagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background, including asbestos exposure. Doctors will also order an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance scan or MRI test, which makes use of radio waves and magnets in order to create a series detailed images of the inside of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. In a surgical biopsy, doctors remove a tiny piece of tissue from pleura or the peritoneum to be tested further. A pathologist can examine the tissue under a microscope to see if it has cancerous cells.

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

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

Treatment

A diagnosis of mesothelioma may be terrifying. It is important to keep in mind, however, that cancer can be treated especially at its early stages. Many patients with mesothelioma be afflicted for many years without it expanding.

Exposure to asbestos can cause mesothelioma through a variety of mechanisms. Asbestos particles, which are too small to detect or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). As time passes, the irritation causes the formation of scar tissue, which causes changes in the structure of cells that eventually develop into tumors.

The Pleura is a protective layer that surrounds the abdomen, heart, and lungs. Mesothelium is composed of cells that react to asbestos which causes it to become inflamed and develop scar tissue. As time passes, these changes lead to the development of malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathing problems and chest pain, or an accumulation of fluid in the lungs (pleural effusion). In rare cases cancer may spread to the tissues around the reproductive organs and heart.

A doctor will request biopsy if imaging scans show the possibility of a lung tumor or stomach. The procedure involves the removal of some of the fluid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and determine the best treatment plan.

There are many types of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ a combination of these treatments. Participating in clinical trials for mesothelioma treatments that are new could be beneficial for patients. To learn more about the trials, patients should speak to a mesothelioma specialist who has expertise in treating the condition.
