Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is made up of thin, long fibres. People who are regularly exposed to asbestos risk developing lung diseases like mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung lining (pleura). It is the most prevalent mesothelioma type and is responsible for 70 to 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 grouping of minerals comprised of microscopic fibres. The fibers, when inhaled cause irritation and DNA mutations. The pleura surrounds the lungs and chest cavity This means that these irritations can affect both the lungs and the heart of a person. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Patients may also experience chest tightness or coughing. They may also experience difficulty breathing. Patients with this type of cancer typically have previous exposure to asbestos in the workplace. The most frequent jobs that expose people to the risk of developing pleural cancer are manufacturing, construction and shipbuilding. People who have worked in the military could be at risk due to the frequent asbestos case use in Navy ships and army bunkers.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used for pleural adenocarcinoma. The stage a patient is in upon diagnosis will assist their doctor in determining the best treatment plan for them. Patients who have pleural mesothelioma which is in stage three or four will suffer a more negative outlook than those in a less advanced stage. Stage four mesothelioma may develop into the liver, heart, or diaphragm. This makes the cancer more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum - a membrane that lines the abdominal cavity and organs such as the intestines and the liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. The disease is less common than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take several years to show. Most patients are afflicted with abdominal pain as well as an abdominal mass. The symptoms of this kind of mesothelioma could also include nausea as well as weight loss and fever. Many of these symptoms could be mistaken for gastrointestinal problems, leading to a misdiagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can identify tumors and other signs of cancer that are not visible on X-rays.

These test results allow doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The stage is determined by the type of cell and whether the cancer has spread.

asbestos claim exposure is the biggest risk factor. People who have worked in jobs which require asbestos attorney, like plumbing manufacturing, electrical work or construction, are at a higher risk of developing the disease. Even if they do not work in these fields they may be exposed to asbestos through family members or other sources. This is why anyone who believes they could be at risk should speak to an expert. A mesothelioma expert can help those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It accounts for as much as the 80% of cases. Exposure to asbestos may occur through military service, work, or living with someone who used to work with asbestos. Asbestos particles can be inhaled by people who are exposed to it. These irritate the linings and can cause cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely to get mesothelioma than people younger or more senior. This is because mesothelioma usually lasts between 20 and 60 years after the initial exposure before symptoms of cancer begin to manifest. It is also important to note that mesothelioma may develop in people who were exposed to asbestos, but did not work with it directly. This is referred to as indirect or secondary asbestos exposure, and is just as harmful as direct asbestos exposure.

Smoking increases the chance of mesothelioma developing, since it damages mesothelium. It also makes it more susceptible. Furthermore, mesothelioma is exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to remember that mesothelioma occurs more frequently in males than females. Men are more likely than women to have been exposed to Asbestos Case for a longer time and to have worked with it. Men are also more likely to have lived with someone who been exposed to asbestos, and to have asbestos fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other conditions. Because of this, victims are often wrongly 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 exposure. Doctors can also order an X-ray of the chest or CT scan to check for lumps and other abnormalities, and also to look for evidence of asbestos exposure in the past such as plaques on the pleura (thickened pleura with calcium deposits) and the buildup 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 as well as a magnetic resonance imaging, or MRI test, which uses magnets and radio waves to make a series of detailed images of the interior of the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. In a surgical biopsy doctors remove a small amount of tissue from the peritoneum or pleura for further testing. A pathologist is then able to look at the tissue under microscopes to determine whether it contains cancerous cells.

The mesothelial type involved, the malignant or benign nature of these cells and the location and stage of the tumour, are used to classify the disease. Certain mesothelioma types have a higher risk of metastasizing or spreading therefore it is essential to establish a clear diagnosis so doctors can treat it before it becomes out of control.

Doctors can also perform laboratory tests on tumors to identify specific genes, proteins or other factors that can aid in describing cancer characteristics and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is crucial to remember, however, that cancer can be treated especially at its early stages. Many people with mesothelioma live for many years without the disease spreading to other parts of their body.

Exposure to asbestos can cause mesothelioma in many ways. Asbestos fibres, too small to be felt or viewed through the naked eye, can become airborne, irritating the lining of the lung (pleura). Over time the irritation causes the formation of scar tissues, which eventually lead to tumors.

The Pleura is a protective layer that protects the lungs, heart and abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. These changes eventually cause mesothelioma cancers.

The signs of pleural mesothelioma can include breathing problems, chest pain or the accumulation of fluid in the lung (pleural effusion). In rare cases, 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, a doctor will order biopsies. During the procedure doctors remove a small amount of fluid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and indicate the best treatment option.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. Most doctors utilize combinations of these treatments. Participating in clinical trials of mesothelioma treatments may be beneficial to patients. To learn more, patients should consult a mesothelioma specialist who has experience treating the condition.
