Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining or pleura. It is the most common type of mesothelioma, making up between 70 and 79% of diagnosed cases. Patients suffering from this condition suffer from chest pain and shortness of breath, and they may feel the sensation of weight in the chest.

Exposure to asbestos, a class of minerals comprised of microscopic fibers, typically causes this kind of cancer. Once inhaled, these fibers stick inside the lung and cause irritation that causes scarring and DNA mutations. Pleura covers both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

The most frequent symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also feel tightness in their chest and coughing, or breathing difficulties. People with this cancer have a past that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are the most prevalent occupations that put people at a high danger of developing pleural melanoma. People who have worked in the military may be at an especially high risk due to the frequent use of asbestos in Navy vessels and bunkers used by the army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most common staging system used to treat pleural adenocarcinoma. The stage that the patient is in at the time of diagnosis can help determine the treatment plan they will receive. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable outlook than those who are in a lower stage. Stage four mesothelioma often spreads to the diaphragm, the liver or even a person's heart. This makes the cancer more difficult to treat, and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum -- an elongated membrane that covers the abdominal cavity and organs like the intestines and liver. Similar to pleural mesothelioma mesothelioma is triggered by asbestos exposure. There are only 300-500 cases diagnosed each year this is less than pleural asbestosis.

As with pleural asbestosis symptoms can take a long time to manifest. Typically, patients are afflicted with abdominal pain as well as abdominal swelling. This mesothelioma type can cause nausea, weight loss, and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can cause incorrect diagnosis.

The doctors can detect mesothelioma through examining the patient's medical history and performing a physical examination. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors as well as other signs of cancer that are not visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also recommend treatments. Staging is determined based on the type of cell and whether or whether the cancer has spread to other areas of the body.

The most important mesothelioma risk factor is asbestos exposure. 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. However, even if people aren't employed in these fields, they can still be exposed to asbestos through relatives or other sources. Therefore, anyone who believes they could be at risk should speak to an expert. A mesothelioma expert can help those with a experience with asbestos to understand more about their risk.

Risk Factors

asbestos law exposure is a major mesothelioma risk factor, making up as much as 80 percent of cases. Exposure to asbestos can occur through military service, work or living with people who have worked with asbestos. When exposed to Asbestos legal, the particles can be breathed into the lungs and abdomen. The particles cause irritation to the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. After asbestos exposure, mesothelioma may be diagnosed between 15 and 60 years old.

Other risk factors include smoking, genetics and the advancing age. People in their 40s or 50s are at greater risk of developing mesothelioma compared to people who are younger or more. This is because mesothelioma usually occurs between 20 and 60 years from the initial exposure before symptoms of cancer begin to manifest. It is important to keep in mind that mesothelioma can be present in people who have been exposed to asbestos without having worked with it directly. This is referred to as secondary or indirect asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It can also make it more vulnerable. In addition, mesothelioma may be exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to know that mesothelioma is more common in men than women. This is because men are more likely to work with asbestos and have more exposure than women. Men are also more likely to have lived with someone who had been exposed to asbestos, and to carry asbestos fibers on their clothing. Women are less likely to come exposed to asbestos and don't typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms can be similar to other diseases. Because of this, victims are sometimes misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient including asbestos exposure. Doctors may also order a chest X-ray 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 formation of fluid between the lung and the chest wall (known as pleural effusion).

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which makes use of radio waves and magnets in order to produce a series of precise images of inside the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. During a surgery biopsy doctors will remove a small piece of tissue from the pleura or the peritoneum, to be further examined. A pathologist is then able to look at the tissue under microscopes to determine if it contains cancerous cells.

Mesothelioma is classified based on the type of mesothelial cell involved, whether those cells are malignant or benign and the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma are more likely to spread or metastasize, so it is important to have a clear diagnosis so that doctors can treat the disease before it goes out of control.

Doctors can also run laboratory tests on a tumor to identify particular proteins, genes and other factors that help them understand the cancer's characteristics 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 is treatable, especially in its early stages. A lot of people suffering from mesothelioma be afflicted for a long time without spreading.

Asbestos exposure can trigger mesothelioma via various mechanisms. asbestos attorney fibers, too small to detect or feel through the naked eye, can become airborne and cause irritation to the lung's lining (pleura). As time passes the irritation can lead to the formation of scar tissues, which eventually lead to tumors.

The pleura is the area that surrounds the lungs and heart, as well as the abdomen. Mesothelium is made up of cells that react to exposure 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 as well as the accumulation of fluid in the lung (pleural effusion). In rare instances cancer can spread to the tissues surrounding the reproductive organs as well as the heart.

If imaging scans reveal a possible mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors will remove a small sample of the fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors utilize combinations of these treatments. Participating in clinical trials of mesothelioma treatments may be beneficial to patients. To learn more, patients should speak with mesothelioma experts who have expertise in treating the condition.
