Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of thin, long fibres. Workers who are regularly exposed to asbestos are at risk of developing lung diseases such as mesothelioma.

Symptoms of these diseases may not show up for decades after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining also known as the pleura. It is the most common type of mesothelioma, making up 70 to 79% of diagnosed cases. This condition causes chest pain, shortness of breathe, and a feeling of heaviness.

This kind of cancer is often caused through exposure to asbestos, which is a collection of minerals that are comprised of microscopic fibres. Once inhaled, these fibers stick inside the lung and cause irritation which results in scarring and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most common symptoms. Patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. People with this cancer have a history that includes asbestos compensation exposure at work. Construction, manufacturing and shipbuilding are the most common occupations which put people at risk risk of developing pleural mesothelioma. People who have served in the military are at a higher risk because of the extensive asbestos use in Navy ships and bunkers used by the army.

The most popular staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient is in upon diagnosis will aid their doctor in determining the most effective treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or four will have a worse prognosis than those who are in a lower stage. Stage four mesothelioma can be spread to the liver, heart, or diaphragm. This makes it more difficult to treat and increases the likelihood of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum, a membrane that lines the abdominal cavity and organs such as the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the primary reason for peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms may take years to appear. Patients typically have abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. A lot of these symptoms are similar to symptoms of digestive issues, which could result in incorrect diagnosis.

Doctors can identify mesothelioma by looking over the medical history of the patient and performing a physical examination. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors, as well as other symptoms of cancer that aren't visible on X-rays.

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 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 jobs that involve asbestos Case, such as plumbing, manufacturing, electrical work or construction, are at increased risk of developing the disease. However, even if individuals aren't employed in these fields they could be exposed to asbestos through relatives or other sources. This is why anyone who is concerned that they might be at risk should talk to an expert. A mesothelioma expert can help those with a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It accounts for up to the 80% of cases. Exposure to asbestos may occur as a result of military service, work, or living with those who worked with asbestos. Asbestos particles can be inhaled by people who are exposed to it. These irritate the linings and trigger cancerous cells to develop in the mesothelium. After exposure to asbestos mesothelioma can occur between 15 and 60 year.

Other risk factors include smoking, genetics and age. 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 occurs between 20 and 60 years from the initial exposure before the first signs of cancer appear. It is important to remember that mesothelioma may develop in people who have been exposed to asbestos litigation, but did not deal with it directly. This is referred to as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases the chance of mesothelioma developing, because it damages the mesothelium. It also makes it more prone to. Furthermore, mesothelioma is exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to remember that mesothelioma occurs more frequently in males than females. Men are more likely than women to have been exposed to asbestos for a longer time and to work with asbestos for longer periods of time. Also, men are more likely to live with someone who was exposed to asbestos and bring asbestos fibers that have escaped home on their clothes. Women are less likely to come into exposure to asbestos and do not typically carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other conditions. This can lead to victims being incorrectly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination and write note of the medical history of the patient which includes asbestos exposure. Doctors may also order an X-ray chest or CT scan to look for lumps and other abnormalities as well as evidence of past asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels, and a magnetic resonance imaging, or MRI, test, which uses magnets and radio waves to create precise images of the inside of the body. Another way doctors can diagnose mesothelioma is by performing the procedure of a surgical biopsy. In a surgical biopsy doctors take a tiny part of tissue from the pleura or the peritoneum, to be tested further. A pathologist will then look at the tissue using a magnifying glass to determine if it is a cancerous cell.

The type of mesothelial cells involved, the malignant or benign nature of the cells, as well as the location and stage of the cancer are used to categorize the disease. Certain mesothelioma types have a higher risk of metastasizing or spreading, so it's important to get a definitive diagnosis to ensure that the doctors can treat it prior to it becoming out of control.

Doctors may also conduct tests in the lab on tumors to identify specific genes, proteins or other elements that will help them identify cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be frightening. It is important to remember, however, that cancer can be treated particularly in its early stages. Many patients with mesothelioma survive for years with the disease, without spreading to other organs of their body.

Exposure to asbestos can cause mesothelioma through a variety of ways. asbestos attorney fibers, which are too small to detect or feel through the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time the irritation can lead to the formation of scar tissue, which eventually lead to tumors.

The pleura is the area that surrounds the heart and lungs and the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. In time, these changes can lead to the development of malignant mesothelioma tumors.

The signs of pleural mesothelioma can include breathlessness and chest pain, or the accumulation of fluid on the lungs (pleural effusion). In rare instances cancer can spread to the tissues around the reproductive organs and heart.

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

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors rely on the combination of these methods. Participating in clinical trials for mesothelioma treatments that are new could be beneficial for patients. Patients can learn more about the trials by consulting a mesothelioma expert who has treated the condition.
