Mesothelioma and Asbestos

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

It can take years for symptoms to appear after exposure to asbestos. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

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

Exposure to asbestos, a group of minerals comprised of microscopic fibers, typically causes this type of cancer. When inhaled, these fibers stick inside the lungs and cause irritation that leads to scarring and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs This means that these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequent symptoms. Some patients may also experience chest tightness or coughing. They may also experience difficulty breathing. People with this cancer often have previous exposure to asbestos lawyer in the workplace. Construction, manufacturing and shipbuilding are the most frequent jobs that put people at high chance of developing pleural mesothelioma. People who have served in the military are at a higher risk because of the extensive use of asbestos in Navy ships and bunkers for 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 a patient is in at the time of diagnosis will help determine what treatment plan they should follow. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis than those who are in a less advanced stage. Mesothelioma in stage four is usually spread to the diaphragm, liver or even the heart of a patient. This can make the cancer more difficult to treat, and increase the risk of complications for patients.

Peritoneal Mesothelioma

Contrary to pleural cancer which is found in the lining of the lung it develops in a membrane that surrounds the abdominal cavity, which includes organs such as the liver and intestines. As with pleural mesothelioma asbestos exposure is the cause of peritoneal msothelioma. The disease is less common than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take years to manifest. Patients usually have abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a mistaken diagnosis.

Typically, doctors can identify mesothelioma after a thorough medical history and physical exam. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can show cancerous tumors or other indications of cancer that aren't visible on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also 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.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have been exposed to asbestos in occupations, like plumbing or electrical work, or in manufacturing and construction, are more likely to contract the disease. Even if a person is not employed in any of these areas however, they may be exposed to asbestos through family members and other sources. Anyone who suspects that they may be at risk should speak with a doctor. A mesothelioma specialist can help those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma, accounting for up to 80 percent of cases. Exposure to asbestos may occur due to military service, work, or living with those who worked with asbestos. Asbestos particles are inhaled by those who are exposed to asbestos. The particles cause irritation to the linings of the lungs, causing cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos lawsuit.

Other risk factors include genetics, smoking and aging. People in their 40s and 50s are more likely to develop mesothelioma than those who are younger or older. This is because mesothelioma usually occurs between 20 and 60 years after the initial time of exposure before the first signs of cancer appear. It is also important to know that mesothelioma is a possibility in people who have been exposed to asbestos lawyer but did not work with it directly. This is known as secondary or indirect exposure to asbestos, and it can be just as dangerous 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. It is also important to know that mesothelioma is more common for men than women. Men are more likely than women to have been exposed to asbestos for a longer period of time and to have worked with it. Also, men are more likely to live with someone who worked with asbestos and carry stray asbestos fibers home on their clothes. Women tend to have less exposure to asbestos and don't typically carry asbestos home on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are often similar to other diseases. Due to this, patients are often misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient, including asbestos exposure. Doctors may also request an CT scan or chest X-ray in order to look for lumps, abnormalities, 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 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 detailed images of the inside of the body. Another way for doctors to detect mesothelioma is through a surgical biopsy. In a surgical biopsy doctors take a tiny piece of tissue from the pleura or the peritoneum to be examined further. A pathologist will then look at the tissue under an magnifying glass to determine whether it contains cancerous cell.

The type of mesothelial cell involved, the malignant or benign nature of these cells and the location, type and stage of the cancer are used to categorize the disease. Certain types of mesothelioma are at greater chance of metastasizing or spreading, so it's important to determine the type of mesothelioma so doctors can treat it prior to it becoming out-of-control.

Doctors can also run laboratory tests on a tumor to find specific proteins, genes and other factors that help them understand the cancer's characteristics and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. But, it is crucial to remember that the disease can be treated, particularly in its earlier stages. A lot of people suffering from mesothelioma live with the disease for a long time without expanding.

Exposure to asbestos can trigger mesothelioma through a variety of ways. Asbestos fibers, too small to see or feel through the naked eye, can be airborne and cause irritation to the lung's lining (pleura). As time passes the irritation causes the formation of scar tissues and eventually tumors.

The pleura covers the lungs and the heart and the abdomen. Mesothelium consists of cells that react to exposure to Asbestos Case; Http://Www.Kdnc.Kr,, causing it to inflame and create scar tissue. Overtime, these changes cause the development of malignant mesothelioma tumors.

Breathing problems, chest discomfort or fluid buildup on the lungs are all signs of pleural Msothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.

A doctor may request biopsy if imaging scans show a potential tumor in the lungs or stomach. During the procedure, doctors remove tiny amounts of fluid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma and indicate the best treatment option.

There are a variety of treatment for mesothelioma, including surgery and chemotherapy. Most doctors use the combination of these treatments. Participating in clinical trials of new mesothelioma treatment may also be beneficial for patients. To learn more, patients should speak to mesothelioma experts who have expertise in treating the condition.
