Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that comes in thin, long fibres. People who are exposed to asbestos may develop lung diseases such as mesothelioma.
The symptoms of these diseases might not be evident for a long time after exposure to asbestos. Different types of asbestos may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma can be found in the lung's outer lining or the pleura. It is the most prevalent mesothelioma form and accounts for 70% to 79% of all diagnosed cases. Patients with this disease suffer from chest pain and breathlessness and may experience an ache or heaviness in the chest.
Exposure to asbestos, a class of minerals composed of microscopic fibers, usually causes this kind of cancer. The fibers, when inhaled cause irritation and DNA mutations. The pleura covers the lungs and chest cavity and therefore, these irritations could affect both the lungs and a person's heart. Mesothelioma symptoms typically don't show until 30 to 50 years after exposure.
The most frequent symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Some patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. Patients with this type of cancer have a past that includes asbestos compensation exposure at work. Manufacturing, construction, and shipbuilding are the most common jobs that put people at a high danger of developing pleural melanoma. Individuals who have been in the military are at a higher risk because of the extensive asbestos use in Navy ships and army bunkers.
The most commonly used staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that a patient is at at diagnosis will aid their doctor in determining the most effective treatment plan for them. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a less favorable prognosis than patients with lower stages. Stage four mesothelioma is often spread to the diaphragm, liver and/or a person's heart. This makes it more difficult to treat and raises the chance of complications for the patient.
Peritoneal Mesothelioma
In contrast to pleural cancer, which forms in the lung's lining the peritoneal cancer is a result of a membrane that covers the abdominal cavity, including organs like the liver and intestines. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed each year which is lower than the pleural asbestosis.
As with pleural asbestosis symptoms can take years to manifest. The majority of patients are afflicted with abdominal pain as well as an abdominal mass. This kind of mesothelioma can cause nausea, weight loss, and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues, leading to a false diagnosis.
Generally speaking, doctors can detect mesothelioma by conducting a thorough health history and physical exam. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors and other symptoms of cancer that aren't visible on an X-ray.
These tests enable doctors to diagnose mesothelioma and determine the stage. They also offer treatment options. Staging is determined based on the cell type and whether or whether the cancer has spread to other areas of the body.
Asbestos exposure is the main risk factor. People who have worked in asbestos-containing professions, such as electrical or plumbing work or in manufacturing and construction are more likely to develop the disease. Even if a person isn't employed in one of these areas, he or she can be exposed to asbestos through family members or other sources. Anyone who suspects that they are at risk should talk to an expert. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will help them find out more about their risk.
Risk Factors
Asbestos exposure is the primary mesothelioma risk factor, accounting for up to 80 percent of cases. Exposure to asbestos can happen due to military service, work, or living with someone who used to work with asbestos settlement. When exposed to asbestos, the particles can be breathed into the abdomen and lungs. These particles irritate the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos compensation.
Other risk factors include smoking, genetics, and age. The people in their 40s or 50s are at a higher risk of developing mesothelioma as compared to those younger or older. This is because mesothelioma usually takes 20 to 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to remember that mesothelioma may develop in people who were exposed to asbestos but did not work with it directly. This is referred to as secondary or indirect asbestos exposure. It can be as dangerous as direct asbestos legal exposure.
Smoking increases the chance of mesothelioma developing, since it damages mesothelium. It can also make it more vulnerable. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work 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 be less exposed to asbestos, and they don't usually carry asbestos on their clothes.
Diagnosis
Mesothelioma is a difficult cancer to diagnose because the symptoms are often similar to other diseases. Due to this, patients are often misdiagnosed.
The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient which includes asbestos exposure. Doctors may also request a CT scan or chest X-ray in order to look for lumps, abnormalities, and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.
Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test, which makes use of magnets and radio waves to create precise images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. In a surgical biopsy doctors will remove a small piece of tissue from the pleura or the peritoneum to be examined further. A pathologist can examine the tissue with microscopes to determine whether it contains cancerous cells.
Mesothelioma is classified based on the type of mesothelial cell involved, whether these cells are malignant or benign and the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma are more likely to spread or metastasize, so it is important to get a definite diagnosis so doctors can treat the disease before it becomes out of control.
Doctors may also conduct laboratory tests on a tumor to identify specific proteins, genes or other elements which can help them identify the cancer's characteristics and plan treatment. These results are known as staging.
Treatment
A mesothelioma diagnosis is a frightening prospect. It is important to remember, however, that cancer can be treated particularly in its initial stages. Many patients with mesothelioma survive for a long time without the disease spreading to other organs of their body.
Exposure to asbestos can cause mesothelioma through various mechanisms. Asbestos fibers, which are too small to be able to see or feel through the naked eye, can become airborne and cause irritation to the lining of the lungs (pleura). Over time the irritation causes the formation of scar tissues and eventually tumors.
The pleura is the area that surrounds the heart and lungs and also the abdomen. Mesothelium is composed of cells that react to asbestos which causes it to become inflamed and form scar tissue. These changes eventually result in malignant mesothelioma tumors.
The symptoms of pleural mesothelioma are breathing problems and chest pain, or an accumulation of fluid in the lungs (pleural effusion). In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.
A doctor will request a biopsy if imaging scans show a potential lung tumor or stomach. In the course of the procedure, doctors remove some of the fluid or tumor for laboratory testing. The results can confirm a mesothelioma diagnosis, and provide the best treatment plan.
There are many types of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize a combination of these treatments. Patients can also benefit by enrolling in a clinical trial of new mesothelioma treatments. Patients can learn more by consulting a mesothelioma specialist who has treated the condition.
