Mesothelioma and Asbestos

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

It may take decades before symptoms begin to manifest after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that affects the lung's outer liner (pleura). It is the most common form of mesothelioma and accounts for 70% to 79% all diagnosed cases. Patients suffering from this condition suffer from chest pain and breath shortness, and they may feel the sensation of weight in the chest.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, usually causes this kind of cancer. Once inhaled, these fibers cling to the lungs and cause irritation that results in scarring and DNA mutations. The pleura surrounds the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma include chest pain and shortness of breath. Some patients may also feel tightness in their chest and coughing, or breathing difficulties. Patients with this cancer have a past that includes asbestos exposure at work. The most frequent jobs that expose workers to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who were in the military are at greater risk due to the extensive use asbestos in Navy vessels and Army bunkers.

The TNM (tumors lymph nodes and metastases staging system) is the most popular staging system for the pleural cancer. The stage the patient is in at the time of diagnosis can help determine the treatment plan they should receive. For example, patients with mesothelioma that is pleural in stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma is often spread to the diaphragm, the liver and/or a person's heart. This makes it more difficult to treat and increases the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, which forms in the lung's lining, peritoneal cancer develops in the membrane that covers the abdominal cavity, including organs such as the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed annually, which is less than pleural asbestosis.

As with pleural asbestosis, symptoms can take several years to show. Most patients suffer from abdominal pain and a mass in the abdomen. This mesothelioma type can also cause nausea, weight loss and fever. Many of these symptoms can be misinterpreted as digestive issues and can lead to a mistaken diagnosis.

Generally speaking, doctors can detect mesothelioma by conducting an extensive health history and physical examination. Imaging tests like X-rays or CT scans can be used to identify mesothelioma. These tests can reveal cancerous tumors or other indications of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. Staging is determined based on the type of cell and whether or whether the cancer has spread to other areas of the body.

Asbestos exposure is the biggest risk factor. People who have been in occupations that involve asbestos, such as plumbing or manufacturing, electrical work, or construction, are at increased risk of developing the disease. However, even if people do not work in these fields they may be exposed to asbestos through relatives or other sources. Anyone who suspects that they are at risk should speak with an expert. A mesothelioma expert can help those who have had a experience with asbestos to understand more about their risk.

Risk Factors

asbestos law is the primary risk factor in mesothelioma. It accounts for up to 80percent of cases. Exposure to asbestos may occur through military service, work, or living with people who have worked with asbestos case (relevant web-site). When exposed to asbestos, particles can be breathed into the abdomen and lungs. The particles cause irritation to the linings of the lungs, causing cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or more senior. It is because mesothelioma generally lasts between 20 and 60 years from the first exposure before cancer symptoms appear. It is important to keep in mind that mesothelioma could occur in those who have been exposed to asbestos without having worked with it directly. This is known as secondary or indirect asbestos exposure, and is as dangerous as direct asbestos legal exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium and makes it more susceptible to asbestos. Mesothelioma is also aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to know that mesothelioma is more common in males than females. Men are more likely than women to have been exposed to asbestos for a longer period of time and to work with asbestos lawyer for longer durations and to work with it. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women tend to be less in contact with asbestos attorney, and they are less likely to carry asbestos on their clothing.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being frequently similar to other illnesses. Because of this, victims are sometimes wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical history, including asbestos exposure. Doctors can also request a chest X-ray or CT scan to check for lumps and other abnormalities, as well as evidence of asbestos exposure in the past like pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance scan or MRI test, that uses magnets and radio waves in order to create a series of detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing an operation called a biopsy. During a surgery biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum, to be tested further. A pathologist will then look at the tissue with a magnifying lens to determine if it is a cancerous cells.

The type of mesothelial cell involved and the benign or malignant nature of these cells, as well as the location and stage of the tumour, are used to categorize the disease. Certain types of mesothelioma are more likely to spread or metastasize and spread, therefore it is essential to get a definite diagnosis so doctors can treat the disease before it goes out of control.

Doctors can also run tests in the laboratory on a tumor to identify specific genes, proteins or other elements which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be terrifying. But, it is crucial to remember that the disease is treatable, particularly in its initial stages. Many mesothelioma patients live for a long time with the disease, without spreading to other areas of their body.

Asbestos exposure can cause mesothelioma by a variety of mechanisms. Asbestos fibers, too small to see or feel by the naked eye can become airborne and irritate the lining of the lungs (pleura). Over time, the irritation causes the formation of scar tissue which leads to changes in the cell structure that can eventually grow into tumors.

The pleura surrounds the heart and lungs and also the abdomen. Mesothelium is composed of cells that react to asbestos, causing it to inflame and create scar tissue. As time passes, these changes cause the development of malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathlessness, chest pain or a buildup of fluid on the lungs (pleural effusion). In rare instances cancer can spread to the tissues that surround the reproductive organs as well as the heart.

A doctor will request biopsy if imaging scans show the possibility of a lung tumor or stomach. During the procedure, doctors will remove small amounts of the tumor or fluid for lab analysis. The results can confirm the diagnosis of mesothelioma and determine the best treatment option.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize the combination of these methods. Participating in clinical trials for mesothelioma treatments that are new could be beneficial for patients. Patients can find out more by speaking with a mesothelioma doctor who has treated the condition.
