Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining or the pleura. It is the most frequent mesothelioma form and accounts for 70% to 79% of all diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling heaviness.

This type of cancer is usually caused by exposure to asbestos which is a collection of minerals composed of microscopic fibers. When inhaled, these fibers can cause irritation and DNA mutations. Pleura is the lining of both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural melanoma are chest discomfort and shortness of breath. Some patients also experience difficulty breathing or chest tightness. Patients with this type of cancer typically have previous exposure to asbestos in the workplace. Manufacturing, construction and shipbuilding are among the most prevalent occupations that put people at high chance of developing pleural mesothelioma. Individuals who have been in the military may be at an especially high risk because of the extensive asbestos use in Navy vessels and bunkers used by the army.

The most common staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at the moment of diagnosis will determine the treatment plan they should receive. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis than those who are in a less advanced stage. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This can make it more difficult to treat and increase the risk of complications for patients.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum -- an elongated membrane that covers the abdominal cavity as well as organs like the intestines and liver. Like pleural mesothelioma, peritoneal mesothelioma is triggered by asbestos exposure. There are only 300-500 cases diagnosed annually this is less than the pleural asbestosis.

Like pleural mesothelioma, the symptoms may take years to appear. Patients typically have abdominal pain, and could also experience a mass in their abdomen. The symptoms of this kind of mesothelioma may also include nausea as well as weight loss and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can result in incorrect diagnosis.

Typically, doctors can identify mesothelioma by conducting an extensive medical history and physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer which aren't visible on X-rays.

These test results allow doctors to diagnose mesothelioma, identify the stage of the disease and suggest treatment options. The stage is determined by the type of cell and whether the cancer has spread.

The most important mesothelioma-related risk factor is asbestos exposure. People who have been in occupations that involve asbestos, such as plumbing or electrical work, manufacturing or construction, are at increased risk of developing the disease. Even if they aren't employed in these areas they may be exposed to asbestos through family members or other sources. For this reason, anyone who suspects they may be at risk should talk to an experienced doctor. If they have an history of exposure to asbestos or mesothelioma, a specialist can assist them in learning more about the risk.

Risk Factors

Asbestos is the primary risk factor in mesothelioma. It accounts for up to 80% of all cases. Exposure to asbestos may occur through work, military service or through living with a person who works with asbestos or used to do so. When exposed to asbestos, small particles can be breathed into the abdomen and lungs. They can cause irritation to the linings of the abdomen and cause cancerous cells to grow in the mesothelium. After exposure to asbestos mesothelioma is likely to develop between 15 and 60 years.

Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are at a higher chance of developing mesothelioma to those younger or older. Mesothelioma can take between 20 and 60 years to show signs of cancer after the first exposure. It is also important to know that mesothelioma can develop in those who were exposed to asbestos but did not work with it directly. This is referred to as secondary or indirect asbestos exposure, and is as hazardous as direct Asbestos Case - Ramiefarmer68.Bravejournal.Net - exposure.

Smoking increases the chance of mesothelioma developing, as it damages the mesothelium. It also makes it more susceptible. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is because men are more likely to work with asbestos and have a longer period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos attorney, and to carry asbestos lawyer fibers on their clothing. Women are less likely to be in contact with asbestos, and they are less likely to bring asbestos home on their clothes.

Diagnosis

It is difficult to recognize mesothelioma since its symptoms are frequently similar to other illnesses. Due to this, patients are sometimes mistakenly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history including asbestos compensation exposure. Doctors can also request an X-ray of the chest or CT scan to detect 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 accumulation of fluid between the lung and the chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart and magnetic resonance imaging, also known as MRI, test, which uses radio waves and magnets to create precise images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing a surgical biopsy. When a biopsy is performed, doctors remove a tiny piece of tissue from the pleura or the peritoneum, to be tested further. A pathologist can examine the tissue under microscopes to determine whether it is contaminated with cancerous cells.

Mesothelioma is classified based on the type of mesothelial cells involved, whether those cells are malignant or benign, and the location, type, and stage of the tumor. Certain mesothelioma types have an increased risk of spreading or metastasizing therefore it is essential to determine the type of mesothelioma to ensure that the doctors can treat it before it becomes out of control.

Doctors can also perform laboratory tests on tumors to determine specific genes, proteins, or other factors which can help them describe cancer characteristics and determine the best treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnosis can be an incredibly frightening prospect. However, it's important to remember that the cancer is treatable, especially in its earlier stages. Many patients with mesothelioma survive for many years with the disease without it spreading to other organs of their body.

Exposure to asbestos may cause mesothelioma in many ways. Asbestos fibers, which are too small to be able to see or feel through the naked eye, can become airborne and irritate the lung's lining (pleura). Over time, the irritation causes the formation of scar tissue which leads to changes in the structure of cells that can eventually grow into tumors.

The Pleura is a protective layer that surrounds the abdomen, heart, and lungs. Mesothelium consists of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. These changes can result in malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathing problems and chest pain as well as a buildup of fluid in the lungs (pleural effusion). In rare cases cancer may 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 remove some of the fluid or tumor for lab tests. The results will confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

There are a variety of mesothelioma treatment options, including surgery, chemotherapy and immunotherapy. The majority of doctors use the combination of these methods. Patients may also benefit from participating in a clinical study of new mesothelioma therapies. Patients can learn more by consulting a mesothelioma specialist who has treated the condition.
