Mesothelioma and Asbestos

Asbestos, a mineral that occurs naturally in the form of thin, long fibers. People who are regularly exposed to asbestos risk developing 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 can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining or the pleura. It is the most prevalent form of mesothelioma and accounts for 70% to 79% all diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling weightiness.

Exposure to asbestos, a group of minerals made of microscopic fibers, typically causes this kind of cancer. The fibers, when inhaled cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity This means that these irritations can affect both the lungs and the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural melanoma are chest pain and shortness of breath. Patients may also experience difficulty breathing, or chest tightness. Patients with this type of cancer have a history that includes asbestos exposure at work. The most frequent jobs that expose workers to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. Individuals who have served in the military are at a greater risk due to the frequent use of asbestos in Navy vessels and Army bunkers.

The TNM (tumors lymph nodes and metastases staging system) is the most popular staging system used for the pleural cancer. The stage the patient is in at the moment of diagnosis will determine what treatment plan they will receive. Patients who have pleural mesothelioma which is in stage three or stage four will have a less favorable prognosis compared to those who are in a lower stage. Stage four mesothelioma can spread to the heart, liver or diaphragm. This can make the cancer more difficult to treat, and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Contrary to pleural cancer that develops in the lining of the lung, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, which includes organs like the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. The disease is less common than pleural mesothelioma, with just 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to show. Most patients suffer from abdominal pain and an abdominal mass. The symptoms of this kind of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms are similar to symptoms of digestive problems, which can cause misdiagnosis.

Doctors can identify mesothelioma by examining the patient's medical history and performing a physical exam. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer which aren't evident on X-rays.

The results of these tests allow doctors to diagnose mesothelioma, identify the stage of the disease and suggest treatment options. The stage is determined by the type of cell as well as whether the tumor has spread.

Asbestos exposure is the main risk factor. People who have been in occupations that require asbestos case, such as plumbing or manufacturing, electrical work or construction, are at a higher risk of developing the disease. However, even if people do not work in these areas, they can still be exposed to asbestos through family members or through other sources. Therefore, anyone who believes they could be at risk should talk to an expert. If they have a history of asbestos lawyer exposure, a mesothelioma specialist can assist them in finding out more about their risk.

Risk Factors

Asbestos is the main mesothelioma-related risk factor. It is responsible for as much as the 80% of cases. Exposure to asbestos may occur due to work, military service or by living with a person who is exposed to asbestos case or has previously done so. When exposed to asbestos, particles are able to be inhaled into lungs and abdomen. These irritate the linings and can cause cancerous cells to grow in the mesothelium. After asbestos exposure mesothelioma is likely to develop between 15 and 60 year.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are at a higher 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 note, too, that mesothelioma can develop in people who have been exposed to asbestos without having directly worked with it. This is called secondary or indirect exposure to asbestos, and it is just as harmful as direct exposure.

Smoking increases the risk of developing mesothelioma due to the fact that it causes mesothelium damage and makes it more susceptible to asbestos. In addition, mesothelioma may be worsened by certain diseases like 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 be exposed to asbestos and endure a an extended period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come exposed to asbestos and they are less likely to carry asbestos on their clothes.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are often similar to other conditions. This can result in patients being misdiagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical history, including asbestos exposure. Doctors may 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 past asbestos exposure like 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, also known as MRI, test, which uses radio waves and magnets to create precise images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. A surgical biopsy is when doctors remove a small amount of tissue from the pleura or peritoneum to conduct further tests. A pathologist will then look at the tissue using an magnifying glass to determine if it is a cancerous cell.

Mesothelioma can be classified based on the type of mesothelial cell involved, whether the cells are benign or malignant and the location, type, and stage of the cancer. Certain types of mesothelioma are at greater risk of spreading or metastasizing and it's crucial to get a definitive diagnosis to ensure that the doctors can treat it before it becomes out of control.

Doctors can also perform laboratory tests on tumors to determine specific proteins, genes, or other factors which can aid in describing cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. It is important to remember that cancer can be treated, particularly in its early stages. A lot of people suffering from mesothelioma endure the disease for many years without it spreading.

Exposure to asbestos can cause mesothelioma in a number of ways. Asbestos fibers, too small to be able to see or feel with the naked eye, can become airborne and irritate the lung's lining (pleura). Over time, the irritation leads to the formation of scar tissues and eventually tumors.

The pleura is a protective covering that protects the abdomen, heart, and lungs. Mesothelium is made up of cells that react when exposed to asbestos lawsuit. They inflame the tissue and cause it to scar. These changes can eventually cause mesothelioma cancers.

Shortness of breath, chest pain or fluid accumulation on the lungs are all indications of pleural msothelioma. In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal an underlying mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors take tiny amounts of fluid or tumor for lab analysis. The results can confirm a mesothelioma diagnosis, and provide the best treatment plan.

There are a variety of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ the combination of these treatments. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial for patients. Patients can learn more by consulting a mesothelioma expert who has treated the disease.
