Mesothelioma and Asbestos
Asbestos, a natural mineral, occurs naturally in the form of long, thin fibers. Workers who are regularly exposed to asbestos risk developing 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 is a type of cancer that develops in the outer lung lining (pleura). It is the most common mesothelioma form and accounts for 70% to 79% all diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling of heaviness.
This type of cancer is usually caused through exposure to asbestos, which is a cluster of minerals that are composed of microscopic fibers. When inhaled, these fibers cling to the lung and cause irritation which results in scarring 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 a person's heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.
Shortness of breath and chest pain are the most frequent symptoms. Patients may also experience difficulty breathing or chest tightness. Patients with this type of cancer have a history that includes asbestos exposure at work. Manufacturing, construction and shipbuilding are among the most common occupations that put people at high chance of developing pleural mesothelioma. People who have served in the military may be at risk due to the frequent asbestos usage in Navy ships and army bunkers.
The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most popular staging system used for the pleural cancer. The stage that a patient is at upon diagnosis will help their doctor determine the most appropriate treatment plan for them. For instance, patients suffering from a pleural mesothelioma in stage three or four have a poorer prognosis than those in a lower stage. Mesothelioma in stage four can develop into the heart, liver or diaphragm. This makes it more difficult to treat and increases the risk of complications for the patient.
Peritoneal Mesothelioma
Unlike pleural cancer, which is found in the lining of the lung, peritoneal cancer develops in a membrane that covers the abdominal cavity, including organs such as the liver and intestines. Like pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.
Like pleural mesothelioma, symptoms can take a long time to manifest. Typically, patients experience abdominal pain and abdominal swelling. This type of mesothelioma may cause nausea, weight loss and fever. A lot of these symptoms are similar to those of digestive problems, which can result in confusion in diagnosis.
Typically, doctors can identify mesothelioma by conducting an extensive health history and physical examination. Imaging tests such as X-rays or CT scans are a way to detect mesothelioma. These tests can show cancerous tumors or other signs of cancer that aren't visible on X-rays.
These test results enable doctors to diagnose mesothelioma and determine the stage. They can also recommend treatments. The stage is determined by the kind of cell and if the cancer has spread.
The most significant mesothelioma risk factor is asbestos exposure. People who have worked in jobs which require asbestos, like plumbing or electrical work, manufacturing or construction, are at a higher risk of developing the disease. Even if an individual does not work in one of these areas however, they may be exposed to asbestos to asbestos litigation through family members and other sources. Anyone who suspects that they're at risk should talk to 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 a major risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos may occur due to military service, work or living with people who have worked with asbestos. When exposed to asbestos, the particles can be breathed into the abdomen and lungs. These irritate the linings and cause cancerous cells to grow in the mesothelium. After asbestos exposure mesothelioma can develop between 15 and 60 years old.
Other risk factors include smoking, genetics, and age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or more senior. This is because mesothelioma usually occurs between 20 and 60 years after 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 settlement but didn't deal with it directly. This is known as secondary or indirect Asbestos Legal exposure and can be as hazardous as direct asbestos exposure.
Smoking increases a person's chances of getting mesothelioma because it damages the mesothelium, which makes it more prone to asbestos. 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 a longer period of time and to work with asbestos for longer periods of time. Men are also more likely to have lived with someone who worked with asbestos and to carry asbestos fibers on their clothing. Women are less likely to come exposed to asbestos settlement and they don't usually carry asbestos on their clothing.
Diagnosis
Mesothelioma is difficult to diagnose because the symptoms are often similar to other conditions. This could lead to patients being incorrectly diagnosed.
The first step in diagnosing mesothelioma is for NYU Langone doctors to perform a physical exam and take notes on the medical history of a patient including asbestos exposure. Doctors may also order an X-ray chest or CT scan to detect lumps and other abnormalities, as well as evidence of asbestos exposure in the past like pleural plaques (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and the chest wall (known as pleural effusion).
Other diagnostic tests include a magnetic resonance image, or MRI test, which makes use of radio waves and magnets to produce a series of precise images of the inside of the body. Another method doctors use to diagnose mesothelioma is through a surgical biopsy. When a biopsy is performed doctors will remove a small piece of tissue from the pleura or the peritoneum to be further examined. A pathologist can then examine the tissue with microscopes to determine if it is contaminated with cancerous cells.
The type of mesothelial cells involved and the benign or malignant nature of those cells, as well as the location, type and stage of the cancer are used to classify the disease. Some types of mesothelioma have an increased 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 can also run tests in the laboratory on tumors to determine particular proteins, genes and other factors which can help them identify the characteristics of cancer and plan treatment. These results are known as staging.
Treatment
A diagnosis of mesothelioma can be a frightening prospect. It is important to keep in mind that cancer can be treated, especially at its early stages. Many patients with mesothelioma endure the disease for many years without it spreading.
Asbestos exposure can cause mesothelioma by various mechanisms. asbestos attorney fibers, which are small enough to not be felt or seen through the naked eye are able to become airborne, causing irritation to the lung's lining (pleura). In time irritation leads to formation of scar tissue which leads to changes in the cell structure that can eventually grow into tumors.
The pleura is the area that surrounds the heart and lungs, as well as the abdomen. Mesothelium is made up of cells that react to asbestos and cause it to enflame and form scar tissue. These changes can eventually result in malignant mesothelioma tumors.
The signs of pleural mesothelioma can include shortness of breath and chest pain as well as a buildup of fluid in the lung (pleural effusion). In rare cases, cancer can spread into the tissues that surround the reproductive organs and the heart.
If imaging scans show a possible mass in the stomach or lungs, a doctor will order biopsies. During the procedure, doctors will remove a small sample of the fluid or tumor for lab analysis. The results will confirm a mesothelioma diagnosis, and provide the best treatment plan.
There are many types of treatment for mesothelioma, such as chemotherapy and surgery. The majority of doctors employ combinations of these treatments. Participating in clinical trials of mesothelioma treatments may be beneficial for patients. To learn more, patients should speak with mesothelioma specialists who have experience treating the condition.
