Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that comes in long, thin fibres. Workers who are exposed to asbestos regularly are at risk of developing mesothelioma or other lung diseases of different types.
The symptoms of these diseases may not manifest for years after exposure to asbestos. Different asbestos types can cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer that occurs in the outer lung the lining (pleura). It is the most frequent mesothelioma form and accounts for 70% to 79% all diagnosed cases. Patients with this disease experience pain in the chest and shortness of breath and may experience an ache or heaviness in the chest.
Exposure to asbestos, a group of minerals comprised of microscopic fibers, usually causes this type of cancer. The fibers, when inhaled can cause irritation and DNA mutations. Pleura covers both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.
Shortness of breath and chest pain are the most frequently reported symptoms. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are the most prevalent occupations that put people at high risk of developing pleural mesothelioma. People who have served in the military could be at a higher risk due to the widespread asbestos usage in Navy vessels and bunkers for the army.
The most commonly used staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has upon diagnosis will aid their doctor in determining the most effective treatment plan for them. For example, patients with a pleural mesothelioma in stage three or four have a worse prognosis than those in lower stages. Stage four mesothelioma is often spread to the diaphragm, the liver and/or a person's heart. This can make the cancer more difficult to treat and increase the risk of complications for the patient.
Peritoneal Mesothelioma
Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum, it is a membrane that lines the abdominal cavity and organs such as the intestines and the liver. Like pleural mesothelioma, asbestos exposure is the primary cause of peritoneal msothelioma. Only 300-500 cases are diagnosed annually which is lower than the pleural asbestosis.
Like pleural mesothelioma, symptoms can take years to show. Patients generally have abdominal pain, and may also have a lump in their abdomen. This mesothelioma type can cause nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a false diagnosis.
Generally, doctors can find mesothelioma after an exhaustive health history and physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors as well as other signs of cancer that are not visible on X-rays.
These test results allow doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. Staging is determined based on the cell type and whether or whether the tumor has spread to other parts of the body.
The most significant risk factor for mesothelioma is exposure to asbestos settlement. People who have been exposed to asbestos in jobs, such as plumbing or electrical work, or in construction and manufacturing, are more likely to develop the disease. However, even if individuals aren't employed in these areas they could be exposed to asbestos through relatives or other sources. For this reason, anyone who believes they could be at risk should speak to a doctor. If they have a history of asbestos exposure, a mesothelioma specialist can help them find out more about their risk.
Risk Factors
Asbestos exposure is the main risk factor for mesothelioma making up as much as 80 percent of cases. Exposure to asbestos can occur through work, military service, or through living with a person who works with asbestos law or used to do such. Asbestos particles can be inhaled by people who are exposed to asbestos. These irritate the linings and can cause cancerous cells to develop in the mesothelium. After exposure to asbestos mesothelioma is likely to occur between 15 and 60 years old.
Other risk factors include smoking, genetics and age. People in their 40s and 50s are more at chance of developing mesothelioma to those younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind, too, that mesothelioma could develop in those who have been exposed to asbestos without having worked with it directly. This is known as secondary or indirect asbestos exposure, and is just as harmful as direct asbestos exposure.
Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more susceptible. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. It is also important to know that mesothelioma is more common for men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with asbestos for longer durations and to work with it. Also, men are more likely to live with someone who has had asbestos exposure and bring asbestos fibers from their workplace on their clothing. Women are less likely to come in contact with asbestos, and they don't usually carry asbestos on their clothes.
Diagnosis
It is difficult to identify mesothelioma due to its symptoms being frequently similar to other illnesses. This is why patients are often wrongly diagnosed.
NYU Langone doctors will perform an examination of the body and document the patient's medical history including asbestos compensation exposure. Doctors will also order an CT scan or chest X-ray to check for lumps, abnormalities 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 image, or MRI test, which uses radio waves and magnets to create a series of detailed images of the insides of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. During a surgical biopsy, doctors remove a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist is then able to examine the tissue under microscopes to determine if it has cancerous cells.
Mesothelioma is classified based on the mesothelial type involved, whether these cells are benign or malignant and the location of the tumor, its type, and the stage of the tumor. Certain types of mesothelioma are at a higher chance of metastasizing or spreading, so it's important to establish a clear diagnosis so that doctors can treat it before it gets out of control.
Doctors may also conduct laboratory tests on tumors to determine specific proteins, genes or other elements that help them understand the characteristics of cancer and plan treatment. These results are known as staging.
Treatment
A mesothelioma diagnosis is terrifying. It is important to remember, however, that cancer can be treated, especially at its early stages. Many patients with mesothelioma live with the disease for a long time without spreading.
Exposure to asbestos can cause mesothelioma in many ways. Asbestos fibres, tiny enough to be felt or viewed through the naked eye can be airborne and irritate the lung's lining (pleura). As time passes the irritation causes the formation of scar tissues that eventually result in tumors.
The pleura covers the lungs and the heart and also the abdomen. Mesothelium consists of cells that react when exposed to asbestos. They inflame the tissue and cause it to scar. These changes can result in malignant mesothelioma tumors.
Shortness of breath, chest discomfort or fluid buildup on the lungs are all indications of pleural Msothelioma. In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.
A doctor will order biopsy if scans show the possibility of a lung tumor or stomach. In the course of the procedure, doctors remove small amounts of fluid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and help determine the best treatment plan.
There are a variety of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors utilize combinations of these treatments. Participating in clinical trials of new mesothelioma treatment may also be beneficial to patients. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated mesothelioma.
