Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma occurs in the lung's outer lining also known as pleura. It is the most prevalent type of mesothelioma, making up between 70 and 79% of all diagnosed cases. Patients with this disease experience pain in the chest and shortness of breath and may also feel a sensation of heaviness in the chest.

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

The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also experience coughing, difficulty breathing or chest tightness. People with this cancer have a history that includes asbestos exposure at work. The most prevalent jobs that expose workers to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who have worked in the military are at risk because of the extensive asbestos usage in Navy vessels and bunkers for the army.

The most common staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has upon diagnosis will assist their doctor in determining the best treatment plan for them. For instance, patients who have a pleural mesothelioma in stage three or four have a less favorable prognosis than patients with a lower stage. Stage four mesothelioma often spreads to the liver, diaphragm and/or a person's heart. This makes it more difficult to treat and raises the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum - an elongated membrane that covers the abdominal cavity as well as organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma, with only about 300-500 cases diagnosed each year.

Like pleural mesothelioma, symptoms may take years to appear. The majority of patients are afflicted with abdominal pain as well as a mass in the abdomen. The symptoms of this kind of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues, leading to a mistaken diagnosis.

Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical exam. They can also utilize imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can identify tumors and other signs of cancer that aren't evident on X-rays.

These tests enable doctors to diagnose mesothelioma, identify the stage of the disease and suggest treatment options. The stage is determined by the kind of cell and if the cancer has spread.

The most important risk factor for mesothelioma is asbestos exposure. People who have worked in asbestos settlement-related jobs, such as plumbing or electrical work, or in construction and manufacturing, are more likely to contract the disease. However, even if individuals aren't employed in these fields they may be exposed to asbestos through family members or other sources. Anyone who thinks they're at risk should talk to an expert. If they have any history of exposure to asbestos, a mesothelioma specialist can help them find out more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, accounting for up to 80 percent of all cases. Exposure to asbestos can happen due to military service, work or living with someone who used to work with asbestos. asbestos compensation particles are inhaled by people who are exposed to asbestos. They can cause irritation to the linings of the abdomen and 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 to get mesothelioma than people younger or more senior. This is because mesothelioma usually lasts between 20 and 60 years after the initial exposure to asbestos before cancer symptoms appear. It is also important to note that mesothelioma may develop in those who were exposed to asbestos but didn't work with it directly. This is referred to as secondary or indirect asbestos litigation exposure, and is just as harmful as direct asbestos exposure.

Smoking can increase the likelihood of getting mesothelioma because it causes mesothelium damage and makes it more vulnerable to asbestos. Additionally, mesothelioma can be exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to know that mesothelioma is more prevalent in males than females. This is due to the fact that men are more likely to work with asbestos and experience a more exposure than women. Men are also more likely to have lived with someone who worked with asbestos and to carry asbestos fibers on their clothing. Women tend to be less exposed to asbestos and they are less likely to bring asbestos claim home on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to identify because the symptoms are often similar to other conditions. This is why patients are sometimes wrongly diagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write note of the medical history of the patient, including asbestos exposure. Doctors can 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 like plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and 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 makes use of magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is another method for doctors to identify mesothelioma. During a surgical biopsy, doctors take a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist then examines the tissue with an magnifying glass to determine if it is a cancerous cell.

Mesothelioma can be classified based on the mesothelial type involved, whether these cells are malignant or benign and the location of the tumor, its type, and the stage of the cancer. Some types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to establish a definitive diagnosis to ensure that doctors are able to treat the disease before it gets out of control.

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

Treatment

A mesothelioma diagnosis can be terrifying. However, it is important to remember that the disease can be treated, particularly in its early stages. Many people with mesothelioma live for years with the disease without it spreading to other parts of their body.

Exposure to asbestos may cause mesothelioma in many ways. Asbestos particles, which are too small to be able to see or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). Over time irritation leads to formation of scar tissue, which causes changes in the cell structure which eventually lead to tumors.

The Pleura is a protective layer that surrounds the abdomen, heart, and lungs. Mesothelium is made up of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. Overtime, these changes lead to the development of malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathlessness, chest pain or a buildup of fluid in the lung (pleural effusion). In rare instances cancer can spread to the tissues surrounding the reproductive organs and the heart.

A doctor will order biopsy if imaging scans show the possibility of a lung tumor or stomach. During the procedure doctors remove small amounts of fluid or tumor to allow for tests in the laboratory. The results can confirm a mesothelioma diagnosis and provide the best treatment plan.

There are a variety of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. Most doctors utilize an amalgamation of these techniques. Patients can also benefit by participating in a clinical study of new mesothelioma treatments. To find out more, patients should consult a mesothelioma specialist who has experience treating the condition.
