15 Terms Everyone Who Works In Mesothelioma And Asbestos Industry Should Know
Mesothelioma and Asbestos
Asbestos is a mineral that naturally occurs in the form of long, thin fibers. People who are exposed to asbestos may develop lung diseases such as mesothelioma.
It can take years before symptoms begin to manifest after exposure to asbestos. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma, a form of cancer, that affects the outer lung the lining (pleura). It is the most common mesothelioma that accounts for up 70% to 79% of all diagnosed cases. Patients with this disease feel chest pain and breathlessness, and they may feel the sensation of weight in the chest.
Exposure to asbestos, a class of minerals composed of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled can cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity, so these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.
The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Some patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. People with this cancer often have previous exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most frequent occupations that put people at a high risk of developing pleural mesothelioma. People who were in the military are at a higher risk due to the widespread use of asbestos in Navy vessels and Army bunkers.
The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system for pleural adenocarcinoma. The stage that a patient is at upon 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 poorer prognosis than those in a lower stage. Stage four mesothelioma may be spread to the heart, liver or diaphragm. This can make it more difficult to treat and increases the risk of complications for the patient.

Peritoneal Mesothelioma
Contrary to pleural cancer which is found in the lining of the lung it develops in a membrane that surrounds the abdominal cavity, which includes organs such as the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. Only 300-500 cases are diagnosed each year this is less than the pleural asbestosis.
As with pleural asbestosis symptoms can take a long time to manifest. Typically, patients suffer from abdominal pain and an abdominal mass. Symptoms of this type of mesothelioma could also include nausea as well as weight loss and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues, leading to a false diagnosis.
Generally speaking, doctors can detect mesothelioma by conducting an extensive health history and physical examination. They can also use imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can detect tumors and other signs of cancer which aren't visible on X-rays.
These tests enable doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.
Asbestos exposure is the biggest risk factor. People who have been in occupations that require asbestos, like plumbing or manufacturing, electrical work or construction, are at increased risk of developing 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 believes they're at risk should speak with a doctor. If they have a history of asbestos exposure and mesothelioma is a concern, a specialist will assist them in learning more about the risk.
Risk Factors
Asbestos exposure is the primary mesothelioma risk factor, making up as much as 80 percent of cases. Exposure to asbestos can occur as a result of military service, work or living with those who worked with asbestos. When exposed to asbestos, small 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. After asbestos exposure mesothelioma can develop between 15 and 60 year.
Other risk factors include smoking, genetics and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or more senior. This is because mesothelioma typically lasts between 20 and 60 years from the initial time of exposure before the first signs of cancer appear. It is also important to know that mesothelioma may develop in those who were exposed to asbestos, but did not deal with it directly. This is known as secondary or indirect asbestos exposure and can be just as harmful as direct asbestos exposure.
Smoking can increase the likelihood of getting mesothelioma because it damages the mesothelium, which makes it more susceptible to asbestos. Nashville asbestos lawyer is also aggravated by certain illnesses such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more prevalent in males than females. Men are more likely than women to have been exposed to asbestos for a longer period of time and to have worked with it. Men are also more likely to live with someone who was exposed to asbestos and bring asbestos fibers from their workplace on their clothes. Women tend to have less contact with asbestos and rarely carry asbestos on their clothing.
Diagnosis
It is difficult to recognize mesothelioma due to its symptoms being often similar to other diseases. Due to this, patients are often mistakenly diagnosed.
NYU Langone doctors will perform physical examinations and document the patient's medical background including asbestos exposure. Doctors can also order a chest X-ray or CT scan to detect lumps and other abnormalities and also to look for evidence of previous asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the formation of fluid between the lung and chest wall (known as the pleural effusion).
Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart and magnetic resonance imaging, or MRI, test, which makes use of radio waves and magnets to make a series of detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing an operation called a biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the pleura or peritoneum for further testing. A pathologist can examine the tissue under a microscope to see if it is contaminated with cancerous cells.
The mesothelial type involved, the malignant or benign nature of those cells as well as the location the cancer, its type and the stage of the cancer are used to categorize the disease. Some types of mesothelioma have greater risk of metastasizing or spreading therefore it is essential to get a definitive diagnosis to ensure that the doctors can treat it prior to it becoming out-of-control.
Doctors can also run laboratory tests on tumors to determine specific proteins, genes, or other factors which can help them identify the cancer's characteristics and plan treatment. These results are known as staging.
Treatment
A mesothelioma diagnose can be frightening. It is crucial to remember, however, that cancer can be treated particularly in its early stages. Many patients with mesothelioma endure the disease for a long time, without spreading.
Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibers, which are too small to detect or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). As time passes irritation can lead to formation of scar tissue, which causes changes in the cell structure which eventually lead to tumors.
The pleura covers the lungs and heart, as well as the abdomen. Mesothelium is composed of cells that react to exposure to asbestos, causing it to inflame and develop scar tissue. Overtime, these changes cause the development of malignant mesothelioma tumors.
A shortness of breath, chest pain or fluid accumulation on the lungs are all symptoms of pleural msothelioma. In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.
If imaging scans show an underlying mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors remove tiny amounts of tumor or fluid for lab testing. The results will confirm the diagnosis of mesothelioma and provide the best treatment option.
There are many types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. Most doctors use a combination of these treatments. Patients could also benefit from enrolling in a clinical trial of new mesothelioma therapies. Patients can learn more about the trials by consulting a mesothelioma specialist who has treated the condition.
