Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that occurs in the outer lung the lining (pleura). It is the most frequent type of mesothelioma, making up 70% to 79% of diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of heaviness.

This kind of cancer is usually caused through exposure to asbestos, which is a cluster of minerals made up of microscopic fibres. The fibers, when inhaled cause irritation and DNA mutations. The pleura covers the lungs and chest cavity This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Patients may also experience chest tightness and coughing, or breathing difficulties. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are the most frequent jobs which put people at risk risk of developing pleural mesothelioma. Individuals who have served in the military are at higher risk due to the extensive use asbestos in Navy vessels and bunkers in the Army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage that a patient is in at the moment of diagnosis will determine the treatment plan they will receive. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable prognosis compared to those who are in a lower stage. Mesothelioma in stage four can be spread to the liver, heart, or diaphragm. This could make the cancer more difficult to treat, and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lung's lining it 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 claim exposure. The disease is less common than pleural mesothelioma, with just 300-500 cases being diagnosed each year.

Like pleural mesothelioma, the symptoms can take years to show. Patients typically have abdominal pain, and may have a mass in their abdomen. Symptoms of this type of mesothelioma may also include nausea, weight loss and fever. Many of these symptoms are similar to symptoms of digestive issues, which could result in misdiagnosis.

Generally, doctors can find mesothelioma by conducting a thorough health history and physical exam. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. These tests can reveal tumors, as well as other symptoms of cancer that aren't visible on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma and establish the stage. They can also recommend treatments. Staging is determined based on the type of cells and whether or whether the tumor has spread to other parts of the body.

Asbestos exposure is the most important risk factor. People who have worked in asbestos-related jobs, such as electrical or plumbing work, or in construction, manufacturing and manufacturing are more likely to contract the disease. Even if an individual does not work in any of these areas however, they may still be exposed through family members and other sources. Anyone who suspects that they may be at risk should speak with a doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can help them find out more about the risk.

Risk Factors

asbestos settlement exposure is the main risk factor for mesothelioma making up as much as 80 percent of all cases. Exposure to asbestos can happen as a result of work, military service or through living with a person who works with asbestos or was previously exposed to doing the same. Asbestos particles can be inhaled by those who are exposed to it. These irritate the linings and can cause cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. This is because mesothelioma usually takes 20 to 60 years from the first exposure before cancer symptoms appear. It is important to remember that mesothelioma can develop in people who were exposed to asbestos but didn't engage directly with it. This is known as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to note that mesothelioma occurs more frequently in men than women. Men are more likely than women to have been exposed to asbestos for a longer time and work with asbestos for longer periods of time. Men are also more likely to have lived with someone who had worked with asbestos case and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and do not typically carry Asbestos case on their clothing.

Diagnosis

Mesothelioma is a difficult disease to diagnose because the symptoms are often similar to other conditions. Due to this, patients are sometimes wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background 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 previous asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, which makes use of radio waves and magnets to create a series detailed images of inside the body. A surgical biopsy is a different way for doctors to diagnose mesothelioma. During a surgery biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum, to be further examined. A pathologist can then examine the tissue with a magnifying glass to determine if it is a cancerous cell.

The mesothelial type involved as well as the benign or malignant nature of those cells as well as the location the cancer, its type and the stage of the cancer are used to classify the disease. Some types of mesothelioma have a higher chance of metastasizing or spreading, so it's important to get a definitive diagnosis to ensure that the doctors can treat it before it gets out of control.

Doctors may also conduct tests in the lab on tumors to determine specific proteins, genes or other factors that will help them identify cancer characteristics and determine the best treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma may be frightening. It is important to keep in mind, however, that cancer can be treated, particularly in its early stages. Many patients with mesothelioma be afflicted for many years without it spreading.

Exposure to asbestos may cause mesothelioma in a number of ways. Asbestos fibres, too small to be felt or seen by naked eyes, can become airborne, causing irritation to the lining of the lung (pleura). Over time irritation leads to formation of scar tissue which can cause changes in the cell structure that eventually develop into tumors.

The pleura surrounds the lungs and heart and the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos legal. They cause inflammation to the tissue and cause it to become scarred. As time passes, these changes cause the development of malignant mesothelioma tumors.

Shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all indications of pleural msothelioma. In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.

A doctor may request biopsy if scans show a potential lung tumor or stomach. During the procedure, doctors take small amounts of the tumor or fluid for lab analysis. The results can confirm the diagnosis of mesothelioma and help determine the most effective treatment plan.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. Most doctors utilize combinations of these treatments. Patients could also benefit from participating in a clinical study of new mesothelioma therapies. To find out more, patients should speak with mesothelioma specialists who have had experience treating the disease.
