Mesothelioma and Asbestos

Asbestos is a mineral that naturally occurs in the form of thin, long fibers. Workers who are exposed to asbestos on a regular basis risk developing mesothelioma and other lung diseases.

It may take decades before symptoms begin to manifest after asbestos attorney exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

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

Exposure to asbestos, a class of minerals made of microscopic fibers, typically causes this kind of cancer. When inhaled, these fibers cause irritation and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma symptoms typically don't show 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 suffer from chest tightness or coughing. They may also experience difficulty breathing. People with this cancer have a history that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are among the most frequent occupations which put people at risk risk of developing pleural mesothelioma. People who have worked in the military are at an especially high risk due to the frequent asbestos use in Navy vessels and army bunkers.

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 receive. Patients who have pleural mesothelioma which is in stage three or stage four will suffer a more negative outlook than those in a lower stage. Stage four mesothelioma is often spread to the liver, diaphragm and/or a person's heart. This makes it more difficult to treat and increases the likelihood of complications for patients.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which 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, asbestos exposure is the cause of peritoneal msothelioma. There are only 300-500 cases diagnosed each year which is lower than pleural asbestosis.

As with pleural mesothelioma symptoms can take years to show. Typically, patients are afflicted with abdominal pain as well as a mass in the abdomen. The symptoms of this kind of mesothelioma may also include nausea as well as weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a misdiagnosis.

Typically, doctors can identify mesothelioma after a thorough medical history and physical exam. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can detect tumors and other signs of cancer that are not evident on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also recommend treatment options. The stage of the disease is determined based on the type of cells and whether or the cancer has spread to other regions of the body.

Asbestos exposure is the most important risk factor. People who have been exposed to asbestos in professions, such as electrical or plumbing work or in construction and manufacturing, are more likely to develop the disease. Even if an individual is not employed in one of these areas however, they may still be exposed to asbestos through family members and other sources. Anyone who thinks they're at risk should consult an expert. If they have a history of asbestos exposure, a mesothelioma specialist can assist them in finding out more about their risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos can happen through work, military service, or by living with someone who is exposed to asbestos or has previously done the same. Asbestos particles can be inhaled by those who are exposed to asbestos. These particles can cause irritation to the linings of the abdomen, which causes cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and age. The people in their 40s or 50s are at greater risk of developing mesothelioma as compared to those younger or older. This is because mesothelioma typically occurs between 20 and 60 years after the initial time of exposure before the first signs of cancer appear. It is also important to note that mesothelioma may develop in people who have been exposed to asbestos case but did not engage directly with it. This is referred to as secondary or indirect exposure to asbestos. It could be as hazardous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it causes mesothelium damage and makes it more susceptible to asbestos legal (Keep Reading). Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is because men are more likely to work with asbestos and experience a a longer period of exposure than women. Men are also more likely to have lived with someone who been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come into contact with asbestos and rarely carry asbestos around on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms are often similar to other diseases. Because of this, victims are often misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history, including asbestos exposure. Doctors will also order a CT scan or chest X-ray to check for lumps, abnormalities and evidence of asbestos exposure. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart and magnetic resonance imaging, or MRI, test that uses magnets and radio waves to create precise images of the inside of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. In a surgical biopsy doctors remove a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist can then examine the tissue under an magnifying glass to determine if it is a cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether those cells are malignant or benign, and the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma may be more likely to develop metastasis or spread, so it is important to establish a definitive diagnosis so that doctors can treat the disease before it becomes out of control.

Doctors may also conduct tests in the lab on a tumor to find specific proteins, genes and other factors that can help them describe the cancer's characteristics and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. But, it is crucial to remember that the cancer is treatable, particularly in its initial stages. A lot of people suffering from mesothelioma live with the disease for many years without it expanding.

Exposure to asbestos can trigger mesothelioma via various mechanisms. asbestos compensation fibers, which are small enough to not be felt or viewed with the naked eyes are able to become airborne, causing irritation to the lung's lining (pleura). In time, the irritation leads to the formation of scar tissue and eventually tumors.

The Pleura is a covering that protects the abdomen, heart, and lungs. Mesothelium is composed of cells that react to exposure to asbestos and cause it to enflame and develop scar tissue. In time, these changes can cause the development of malignant mesothelioma tumors.

Breathing problems, chest pain or fluid accumulation on the lungs are all indications of pleural msothelioma. In rare instances cancer may spread to the tissues around the reproductive organs and the heart.

If scans of imaging reveal an underlying mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors remove tiny amounts of fluid or tumor for laboratory tests. The results can confirm the diagnosis of mesothelioma and determine the best treatment option.

There are several types of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. Most doctors rely on the combination of these methods. Participating in clinical trials for mesothelioma treatments that are new could be beneficial to patients. To find out more, patients should speak with a mesothelioma specialist who has expertise in treating the condition.
