Mesothelioma and Asbestos

Asbestos is a natural mineral that comes in thin, long fibres. People who are exposed to asbestos regularly are at risk of developing mesothelioma as well as other lung diseases.

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

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that affects the lung's outer lining (pleura). It is the most frequent mesothelioma type and is responsible for 70 to 79% of all diagnosed cases. People with this condition suffer from chest pain and breath shortness and may also feel the sensation of weight in the chest.

This kind of cancer is usually caused by exposure to asbestos which is a collection of minerals that are comprised of microscopic fibres. When inhaled, these fibers cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and shortness of breath. Some patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this cancer have a history that includes asbestos exposure at work. The most frequent jobs that put people at risk of developing pleural cancer are manufacturing, construction, and shipbuilding. People who served in the military are at a higher risk due to the extensive use asbestos case in Navy vessels and bunkers in the Army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most common staging system for the pleural cancer. The stage a patient has at diagnosis will aid their doctor in determining the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a worse outlook than those in a lower stage. Mesothelioma in stage four can be spread to the heart, liver or diaphragm. This makes the cancer more difficult to treat, and increase the risk of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, which forms in the lung's lining, peritoneal cancer develops in the membrane that covers the abdominal cavity, including organs such as the intestines and liver. Like pleural mesothelioma, asbestos exposure is the primary cause of peritoneal mesothelioma. Only 300-500 cases are diagnosed each year, which is less than pleural asbestosis.

Like pleural mesothelioma, the symptoms can take years to show. The majority of patients are afflicted with abdominal pain as well as abdominal swelling. Symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms could be mistaken for gastrointestinal problems which can lead to a misdiagnosis.

Typically, doctors can identify mesothelioma after a thorough health history and physical examination. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can detect tumors and other cancer signs which aren't evident on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the type of cell and whether the tumor has spread.

Asbestos exposure is the main risk factor. People who have worked in asbestos-related jobs, such as plumbing or electrical work, or in construction, manufacturing and manufacturing are more likely to contract the disease. However, even if individuals aren't employed in these areas they may be exposed to asbestos through family members or other sources. Anyone who believes they are at risk should speak with a doctor. A mesothelioma specialist can help those who have had a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos is the primary mesothelioma-related risk factor. It is responsible for up to the 80% of cases. Exposure to asbestos lawyer can occur due to military service, work, or living with people who have worked with asbestos. When exposed to asbestos, particles can be breathed into the abdomen and lungs. They can cause irritation to the linings of the abdomen and can cause cancerous cells to form in the mesothelium. After asbestos legal exposure mesothelioma can be diagnosed between 15 and 60 year.

Other risk factors include smoking, genetics, and age. People in their 40s and 50s are more likely to get mesothelioma than people younger or more senior. This is because mesothelioma typically lasts between 20 and 60 years from the first exposure to asbestos before the first signs of cancer appear. It is important to note that mesothelioma may develop in those who have been exposed to asbestos, but without having been directly exposed to it. This is called secondary or indirect exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more susceptible. Furthermore, mesothelioma is caused by certain illnesses, such as pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to have worked with it. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and don't typically carry asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms are often similar to other conditions. Because of this, victims are sometimes wrongly diagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical history, including asbestos exposure. Doctors can also order an X-ray of the chest or CT scan to check for lumps and other abnormalities and also to look for evidence of previous asbestos law exposure like pleural plaques (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which uses magnets and radio waves to create a series detailed images of the inside of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. During a surgery biopsy doctors take a tiny piece of tissue from the pleura or the peritoneum to be further examined. A pathologist can examine the tissue with a microscope to see if it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether the cells are malignant or benign and also the location, type, and stage of the tumor. Some types of mesothelioma are more likely to spread or metastasize which is why it is crucial to establish a definitive diagnosis to ensure that doctors are able to treat the disease before it becomes out of control.

Doctors may also conduct tests in the lab on tumors to determine specific genes, proteins or other elements which can help them identify the cancer's characteristics and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnosis is terrifying. However, it's important to remember that the disease is treatable, particularly in its earlier stages. Many mesothelioma patients live for many years without the disease spreading to other areas of their body.

Exposure to asbestos can cause mesothelioma in a number of ways. Asbestos fibers, too small to see or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). As time passes the irritation can lead to the formation of scar tissue, which eventually lead to tumors.

The pleura is the area that surrounds the lungs and the heart, as well as the abdomen. Mesothelium is composed of cells that react to exposure to asbestos compensation which causes it to become inflamed and form scar tissue. These changes can eventually cause mesothelioma cancers.

Breathing problems, chest pain or fluid accumulation on the lungs are all signs of the pleural Msothelioma. In rare cases, the cancer can spread to the tissues surrounding the heart and reproductive organs.

A doctor will request biopsy if imaging scans show the possibility of a tumor in the lungs or stomach. The procedure involves the removal of small amounts of liquid or tumor for laboratory testing. The results will confirm a mesothelioma diagnosis and provide the best treatment plan.

There are several types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. Most doctors utilize the combination of these treatments. Participating in clinical trials for new mesothelioma treatment may also be beneficial for patients. Patients can learn more about the trials by consulting a mesothelioma expert who has treated mesothelioma.
