Mesothelioma and Asbestos

Asbestos, a mineral that naturally forms in the form of thin, long fibers. People who are exposed to asbestos regularly are at risk of developing mesothelioma or other lung diseases of different types.

The symptoms of these diseases might not manifest for years after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

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

Exposure to asbestos, a group of minerals comprised of microscopic fibers, usually causes this type of cancer. Once inhaled, the fibers are absorbed into the lung and cause irritation that causes scarring and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural melanoma are chest discomfort and shortness of breath. Some patients may also feel tightness in their chest, coughing or difficulty breathing. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. The most common jobs that put people at risk of developing pleural cancer are manufacturing, construction and shipbuilding. Individuals who have been in the military may be at an especially high risk because of the extensive asbestos usage in Navy ships and bunkers for the army.

The most popular staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient is in at the moment of diagnosis will determine what treatment plan they should follow. For example, patients with mesothelioma pleural stage three or four have a less favorable prognosis than those with lower stages. Mesothelioma in stage four is usually spread to the diaphragm, the liver and/or a person's heart. This makes it more difficult to treat and increase the chance of complications for the patient.

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 the liver. Like pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. There are only 300-500 cases diagnosed annually which is lower than pleural asbestosis.

As with pleural asbestosis, symptoms can take a long time to show. The majority of patients experience abdominal pain and an abdominal mass. This kind of mesothelioma can cause nausea, weight loss, and fever. A lot of these symptoms can be misinterpreted as digestive issues and can lead to a mistaken diagnosis.

Generally, doctors can find mesothelioma after an exhaustive health history and physical examination. They can also use imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal cancerous tumors or other symptoms of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They also offer treatment options. The stage is determined by the kind of cell and if the tumor has spread.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have been in occupations that involve asbestos attorney, such as plumbing or manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if a person does not work in one of these fields they could be exposed to asbestos through family members or other sources. For this reason, anyone who suspects they may be at risk should speak to an experienced doctor. A mesothelioma specialist can help those who have a experience with asbestos to understand more about their risk.

Risk Factors

asbestos lawyer exposure is the main risk factor for mesothelioma, making up as much as 80 percent of cases. Exposure to asbestos legal can happen as a result of work, military service or through living with a person who works with asbestos or used to do the same. When exposed to asbestos, particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings and can cause cancerous cells to form in the mesothelium. After asbestos exposure, mesothelioma may develop between 15 and 60 years.

Other risk factors include smoking, genetics, and the advancing age. The people in their 40s or 50s are more at chance of developing mesothelioma to those who are younger or older. It takes mesothelioma 20-60 years to show signs of cancer after the first exposure. It is important to keep in mind, too, that mesothelioma could occur in people who have been exposed to asbestos without having directly worked with it. This is known as secondary or indirect asbestos exposure, and is as hazardous as direct asbestos exposure.

Smoking can increase the likelihood of developing mesothelioma since it damages the mesothelium and makes it more susceptible to asbestos. Additionally, mesothelioma can be exacerbated by certain illnesses like asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos and experience a a longer period of exposure than women. Additionally, men are more likely to live with someone who has worked with asbestos lawsuit and carry asbestos fibers from their workplace on their clothes. Women tend to have less contact with asbestos case (click the following page) and rarely carry asbestos around on their clothes.

Diagnosis

Mesothelioma is difficult to diagnose because the symptoms are often similar to other diseases. Due to this, patients are often wrongly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient including asbestos exposure. Doctors may also request a CT scan or chest X-ray to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance scan or MRI test, which makes use of magnets and radio waves to produce a series of precise images of inside the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. In a surgical biopsy doctors remove a small piece of tissue from the pleura or peritoneum to conduct further tests. A pathologist can look at the tissue under a microscope to see if it is contaminated with cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of those cells as well as the location, type and stage of the cancer are used to classify the disease. Certain mesothelioma types have a higher chance of metastasizing or spreading therefore it is essential to get a definitive diagnosis so that doctors can treat it before it becomes out of control.

Doctors can also perform tests in the laboratory on tumors in order to determine specific genes, proteins or other factors that will help them identify the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnose can be frightening. It is important to remember, however, that cancer can be treated particularly in its initial stages. Many mesothelioma patients live for years with the disease without it spreading to other areas of their body.

Exposure to asbestos can cause mesothelioma through many mechanisms. Asbestos fibers, too small to see or feel with the naked eye, can become airborne and irritate the lung's lining (pleura). As time passes the irritation can lead to the formation of scar tissues that eventually result in tumors.

The Pleura is a protective layer that protects the lungs, heart and abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. Overtime, these changes cause the development of malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness and chest pain, or the accumulation of fluid in the lungs (pleural effusion). In rare instances, the cancer can grow to the tissues surrounding the heart and reproductive organs.

A doctor may request biopsy if scans show the possibility of a mass in the lungs or stomach. During the procedure, doctors take a small sample of the tumor or fluid for lab testing. The results will confirm the diagnosis of mesothelioma and provide the best treatment option.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. The majority of doctors employ combinations of these treatments. Participating in clinical trials for mesothelioma treatments that are new could be beneficial for patients. To learn more, patients should speak to mesothelioma experts who have experience treating the condition.
