10 Fundamentals To Know Mesothelioma And Asbestos You Didn't Learn In School

Mesothelioma and Asbestos

Asbestos is a mineral that naturally occurs in the form of long, thin fibers. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma or other lung diseases of different types.

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

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that occurs in the lung's outer the lining (pleura). It is the most common mesothelioma that accounts for up between 70 and 79% of all diagnosed cases. The condition can cause chest pain, breath shortness and a feeling heaviness.

This kind of cancer is typically caused through exposure to asbestos, which is a cluster of minerals composed of microscopic fibers. Once inhaled, the fibers stick inside the lung and cause irritation that causes scarring and DNA mutations. Pleura is the lining of 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.

Chest pain and shortness breath are the most common symptoms. Some patients also experience difficulty breathing, or chest tightness. People with this cancer have a history of disease that includes asbestos exposure at work. The most common jobs that put people at risk of pleural mesothelioma include construction, manufacturing and shipbuilding. Individuals who have served in the military are at a higher risk due to the frequent use of asbestos in Navy vessels and bunkers for the Army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used for pleural adenocarcinoma. The stage a patient is in at the time of diagnosis will help determine what treatment plan they should receive. For  Spokane Valley asbestos lawyer , patients with mesothelioma that is pleural in stage three or four have a worse prognosis than those with a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver or even the heart of a patient. This can make it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum, it is a membrane that lines the abdominal cavity and organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed each year, which is less than pleural asbestosis.

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 can also include nausea or weight loss, as well as fever. Many of these symptoms are similar to those of digestive issues, which could result in confusion in diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and conducting a physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can show tumors, as well as other indications of cancer that aren't visible on an X-ray.

These tests enable doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the kind of cell and if the tumor has spread.

Asbestos exposure is the main risk factor. People who have worked in asbestos-related jobs, such as electrical or plumbing work, or in manufacturing and construction, are more likely to contract the disease. Even if they aren't employed in these areas, they can still be exposed to asbestos through relatives or other sources. For this reason, anyone who suspects they may be at risk should talk to an experienced doctor. A mesothelioma specialist can help those who have a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is the primary mesothelioma risk factor, making up as much as 80 percent of all cases. Exposure to asbestos can occur due to work, military service, or living with people who have worked with asbestos. When exposed to asbestos, small particles are able to be inhaled into abdomen and lungs. These particles irritate the linings of the lungs, causing cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include genetics, smoking and age. The people in their 40s or 50s are at a higher risk of developing mesothelioma as compared to those younger or older. Mesothelioma can take between 20 and 60 years to show signs of cancer after the first exposure. It is also important to know that mesothelioma is a possibility in people who have been exposed to asbestos, but did not work with it directly. This is referred to as secondary or indirect exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be caused by certain illnesses such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for longer periods of time and work with asbestos for longer periods of time. Additionally, men are more likely to live with someone who has worked with asbestos and carry asbestos fibers from their workplace on their clothes. Women tend to have less contact with asbestos and do not typically carry asbestos around on their clothing.

Diagnosis

It is difficult to recognize mesothelioma because its symptoms are often similar to other diseases. This could lead to patients being misdiagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background, including asbestos exposure. Doctors may also order an X-ray of the chest or CT scan to look for lumps or other abnormalities, and also to look for evidence of previous asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the formation 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, also known as MRI, test that uses magnets and radio waves to create detailed images of the interior of the body. Another method doctors use to diagnose mesothelioma is through the procedure of a surgical biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist can then examine the tissue under microscopes to determine whether it has cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of these cells and the location the cancer, its type and the stage of the tumour, are used to categorize the disease. Some types of mesothelioma have greater chance of metastasizing or spreading, so it's important to get a definitive diagnosis to ensure that the doctors can treat it before it becomes out of control.

Doctors may also conduct tests in the lab on a tumor to find specific proteins, genes and other factors that help them understand the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

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

Exposure to asbestos can trigger mesothelioma via many mechanisms. Asbestos fibers, which are too small to be able to see or feel with the naked eye, can become airborne and cause irritation to the lung's lining (pleura). In 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 covering that protects the lungs, heart and abdomen. Mesothelium is composed of cells that react to asbestos and cause it to enflame and develop scar tissue. Overtime, these changes cause the development of malignant mesothelioma cancers.

Symptoms of pleural mesothelioma include breathing problems and chest pain, or a buildup of fluid on the lungs (pleural effusion). In rare cases, cancer can spread into the tissues surrounding the reproductive organs as well as the heart.

If imaging scans reveal an underlying mass in the stomach or lungs doctors will recommend a biopsies. The procedure involves the removal of small amounts of liquid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and determine the best treatment option.

There are many types of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize a combination of these methods. Patients may also benefit from enrolling in a clinical trial of new mesothelioma therapies. Patients can learn more by consulting a mesothelioma expert who has treated mesothelioma.
