Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that is made up of thin, long fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases, such as mesothelioma.
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 affects the lung's outer liner (pleura). It is the most common form of mesothelioma and is responsible for 70 to 79% all diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling of weightiness.
This type of cancer typically caused by exposure to asbestos compensation, which is a collection of minerals made up of microscopic fibres. These fibers, when inhaled can cause irritation and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.
Chest pain and shortness breath are the most frequently reported symptoms. Patients may have coughing problems, trouble breathing or chest tightness. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. The most frequent jobs that expose people to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. Individuals who have served in the military are at a greater risk due to the extensive use asbestos in Navy vessels and Army bunkers.
The most common staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that the patient is in at the time of diagnosis can help determine what treatment plan they should follow. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis compared to those in a less advanced stage. Stage four mesothelioma often spreads to the diaphragm, liver or even a person's heart. This can make it more difficult to treat and raises the risk of complications for the patient.
Peritoneal Mesothelioma
As opposed to pleural mesothelioma that develops in the lung lining, peritoneal mesothelioma is found in the peritoneum -- a membrane that lines the abdominal cavity as well as organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. There are only 300-500 cases diagnosed each year which is lower than pleural asbestosis.
As with pleural asbestosis symptoms can take a long time to manifest. The majority of patients suffer from abdominal pain and a mass in the abdomen. This mesothelioma type can cause nausea, weight loss, and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a misdiagnosis.
Doctors can detect mesothelioma by reviewing the medical history of the patient and conducting a physical exam. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can show tumors and other signs of cancer that aren't visible on X-rays.
The results of these tests allow doctors to diagnose mesothelioma and determine the stage and suggest treatment options. The stage is determined by the kind of cell and if the tumor has spread.
The most significant mesothelioma-related risk factor is asbestos exposure. People who have been in occupations which require asbestos settlement, such as plumbing, manufacturing, electrical work, or construction, are at a higher risk of developing the disease. However, even if individuals aren't employed in these areas they could be exposed to asbestos through family members or other sources. Anyone who thinks they are at risk should talk to an expert. If they have a history of asbestos exposure or mesothelioma, a specialist can assist them in finding out more about their risk.
Risk Factors
Asbestos is the primary risk factor in mesothelioma. It accounts for up to the 80% of cases. Exposure to asbestos may occur due to work, military service, or by living with someone who is exposed to asbestos or was previously exposed to doing such. Asbestos particles are inhaled by those who are exposed to asbestos. These irritate the linings and can cause cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.
Other risk factors include genetics, smoking and age. The people in their 40s or 50s are more at chance of developing mesothelioma to people who are younger or more. It takes mesothelioma 20-60 years to manifest cancer symptoms after the first exposure. It is important to note that mesothelioma can be present in people who have been exposed to asbestos, but without having directly worked with it. This is referred to as secondary or indirect exposure to asbestos. It can be just as dangerous as direct exposure.
Smoking increases a person's chances of getting mesothelioma because it damages the mesothelium, which makes it more vulnerable to asbestos. In addition, mesothelioma may be exacerbated by certain illnesses like pneumonia and asbestosis. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for a longer period of time and work with asbestos for longer periods of time. Men are also more likely to live with someone who has was exposed to asbestos and bring asbestos fibers from their workplace on their clothes. Women tend to have less exposure to asbestos case and do not typically carry asbestos around on their clothing.
Diagnosis
Mesothelioma is a difficult disease to recognize because the symptoms often resemble other conditions. Because of this, victims are often wrongly diagnosed.
NYU Langone doctors will perform a physical examination and record the patient's medical background, including asbestos exposure. Doctors may also order an X-ray chest or CT scan to check for lumps and other abnormalities as well as evidence of asbestos exposure in the past like plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as pleural effusion).
Other diagnostic tests include a magnetic resonance image or MRI test, that uses radio waves and magnets in order to create a series detailed images of the inside of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum to conduct further tests. A pathologist then examines the tissue under a magnifying glass to determine if it is a cancerous cell.
The type of mesothelial cells involved as well as the benign or malignant nature of those cells as well as the location and stage of the cancer are used to categorize the disease. Certain types of mesothelioma are more likely to develop metastasis or spread which is why it is crucial to establish a definitive diagnosis so doctors can treat the disease before it gets out of control.
Doctors may also conduct tests in the lab on a tumor to find specific genes, proteins, or other factors that help them understand the characteristics of the cancer and determine a treatment. These results are referred to as staging.
Treatment
A mesothelioma diagnose can be terrifying. It is important to keep in mind, however, that cancer can be treated especially at its early stages. Many people with mesothelioma can endure the disease for a long time without spreading.
Exposure to asbestos case can trigger mesothelioma through a variety of ways. Asbestos fibers, too small to be able to see or feel with the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time the irritation causes the formation of scar tissues, which eventually lead to tumors.
The pleura covers the lungs and heart and the abdomen. Mesothelium is composed of cells that react to asbestos and cause it to enflame and develop scar tissue. In time, these changes can result in the growth of malignant mesothelioma tumors.
Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all indications of pleural Msothelioma. In rare instances the cancer may be spread to the tissues around the heart and reproductive organs.
A doctor will request biopsy if scans show the possibility of a tumor in the lungs or stomach. During the procedure doctors remove a small amount of liquid or tumor for lab tests. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment option.
There are many types of treatment for mesothelioma including surgery and chemotherapy. Most doctors utilize the combination of these treatments. Participating in clinical trials of mesothelioma treatments may be beneficial to patients. Patients can learn more by speaking with a mesothelioma doctor who has treated the disease.
