Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in long, thin fibres. People who are regularly exposed to asbestos risk developing lung diseases like mesothelioma.

It can take years for symptoms to show up after exposure to asbestos compensation. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that occurs in the outer lung liner (pleura). It is the most frequent type of mesothelioma, making up 70 to 79% of all diagnosed cases. People with this condition suffer from chest pain and shortness of breath and may experience the sensation of weight in the chest.

This kind of cancer is usually caused by exposure to asbestos, which is a collection of minerals that are composed of microscopic fibers. The fibers, when inhaled cause irritation and DNA mutations. The pleura covers the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. Patients with this type of cancer have a history of disease that includes asbestos exposure at work. Manufacturing, construction, and shipbuilding are the most common jobs which put people at risk chance of developing pleural mesothelioma. People who have worked in the military may be at risk due to the frequent use of asbestos in Navy vessels and army bunkers.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient has at diagnosis will assist their doctor in determining the most appropriate treatment plan for them. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a worse prognosis than those with a lower stage. Mesothelioma in stage four can develop into the heart, liver or diaphragm. This can make it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lung's lining the peritoneal cancer is a result of a membrane that covers the abdominal cavity, which includes organs such as the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. There are only 300-500 cases diagnosed each year this is less than pleural asbestosis.

As with pleural mesothelioma symptoms can take years to show. The majority of patients experience abdominal pain and a mass in the abdomen. The symptoms of this kind of mesothelioma could also include nausea as well as weight loss and fever. A lot of these symptoms are similar to those experienced by gastrointestinal issues, which can cause confusion in diagnosis.

Generally speaking, doctors can detect mesothelioma after a thorough health history and physical examination. Imaging tests like X-rays and CT scans are a way to identify mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't apparent on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma, determine the stage of the disease and suggest treatment options. Staging is determined based on the type of cells and whether or not the tumor has spread to other parts of the body.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have been exposed to asbestos legal in professions, such as electrical or plumbing work or in construction and manufacturing are more likely to contract the disease. Even if a person isn't employed in one of these areas, he or she can be exposed to asbestos to asbestos through family members and other sources. For this reason, anyone who believes they could be at risk should talk to an experienced doctor. A mesothelioma expert can help those with a history with asbestos to learn more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, which accounts for as much as 80 percent of all cases. Exposure to asbestos may occur due to military service, work, or living with someone who used to work with asbestos. Asbestos particles can be breathed in by those who are exposed to it. These particles irritate the linings, 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 at greater chance of developing mesothelioma to those younger or older. Mesothelioma can take between 20 and 60 years to manifest cancer symptoms after the first exposure. It is important to remember that mesothelioma could be present in those who have been exposed to asbestos without having directly worked with it. This is known as secondary or indirect asbestos exposure, and is just as harmful as direct asbestos exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be aggravated by certain illnesses, including 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 a longer period of time and to work with it. Men are also more likely to have lived with someone who worked with asbestos, and to have asbestos Legal fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos on their clothing.

Diagnosis

It is difficult to recognize mesothelioma due to its symptoms being often similar to other diseases. Due to this, patients are sometimes wrongly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors can also order an X-ray chest or CT scan to look for lumps or other abnormalities, and also to look for evidence of previous asbestos exposure such as plaques in the pleura (thickened pleura with calcium deposits) and the formation 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, which uses radio waves and magnets to create a series detailed images of the inside of the body. A surgical biopsy is yet 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 can then examine the tissue using a magnifying lens to determine whether it contains cancerous cell.

Mesothelioma is classified based on the type of mesothelial cell involved, whether the cells are benign or malignant and the location of the tumor, its type, and the stage of the tumor. 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 may also conduct laboratory tests on a tumor to identify particular proteins, genes, or other factors that help them understand the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be frightening. But, it is crucial to remember that the disease is treatable, especially in its early stages. Many people with mesothelioma can be afflicted for many years without it spreading.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos fibres, too small to be felt or seen through the naked eye, can become airborne, causing irritation to the lining of the lung (pleura). As time passes irritation leads to formation of scar tissue, which causes changes in the structure of cells which eventually lead to tumors.

The Pleura is a protective layer that covers the lungs, heart and abdomen. Mesothelium is composed of cells that respond when exposed to asbestos claim. They cause inflammation to the tissue and cause it to scar. These changes eventually lead to malignant mesothelioma tumours.

The signs of pleural mesothelioma can include shortness of breath and chest pain, or a buildup of fluid in the lung (pleural effusion). In rare cases cancer can spread to the tissues that surround the reproductive organs as well as the heart.

A doctor will request biopsy if scans reveal a possible lung tumor or stomach. During the procedure, doctors remove a small sample of the fluid or tumor for lab testing. The results will confirm a mesothelioma diagnosis, and provide the best treatment plan.

There are a variety of treatment for mesothelioma, such as chemotherapy and surgery. Most doctors utilize a combination of these treatments. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatment. Patients can find out more by consulting a mesothelioma specialist who has treated mesothelioma.
