본문
Asbestos is a natural mineral that comes in long, thin fibres. Workers who are exposed to asbestos regularly risk developing mesothelioma and other lung diseases.
The symptoms of these diseases might not show up for decades after exposure to asbestos compensation. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a type of cancer that affects the lung's outer liner (pleura). It is the most common mesothelioma that accounts for up between 70 and 79% of diagnosed cases. People with this condition experience pain in the chest and breath shortness and may also feel a sensation of heaviness in the chest.
Exposure to Asbestos Legal, a class of minerals made of microscopic fibers, typically causes this kind of cancer. The fibers, when inhaled, cause irritation and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, so irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.
The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also experience 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. The most common jobs that expose people to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who served in the military are at a higher risk due to the frequent use of asbestos in Navy vessels and bunkers for the Army.
The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system for the pleural cancer. The stage that a patient is in at the time of diagnosis will help determine what treatment plan they will receive. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable outlook than those who are in a less advanced stage. Mesothelioma in stage four is usually spread to the liver, diaphragm or even a person's heart. This can make the cancer more difficult to treat and increase the chance of complications for patients.
Peritoneal Mesothelioma
Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum - an elongated membrane that covers the abdominal cavity as well as organs like the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma can be caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.
Like pleural mesothelioma, the symptoms can take a long time to manifest. Patients typically suffer from abdominal pain and could also experience a mass in their abdomen. This mesothelioma type can also cause nausea, weight loss, and fever. A lot of these symptoms are similar to those experienced by gastrointestinal issues, which can cause misdiagnosis.
Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. Imaging tests like X-rays and CT scans are a way to identify mesothelioma. These tests can show tumors and other symptoms of cancer that aren't apparent on an X-ray.
These test results enable doctors to diagnose mesothelioma and determine the stage. They also offer treatments. Staging is determined based on the type of cells and whether or not the tumor has spread to other areas of the body.
The most important mesothelioma risk factor is exposure to asbestos. People who have been in occupations that require asbestos, such as plumbing or electrical work, manufacturing or construction, are at greater risk of developing the disease. However, even if individuals aren't employed in these fields they may be exposed to asbestos through relatives or other sources. Therefore, anyone who believes they could be at risk should speak to a doctor. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in finding out more about their risk.
Risk Factors
Asbestos is the main risk factor in mesothelioma. It is responsible for up to 80percent of cases. Exposure to asbestos may occur as a result of military service, work, or living with someone who used to work with asbestos. When exposed to asbestos, the particles can be inhaled into the lungs and abdomen. These irritate the linings and trigger cancerous cells to develop in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.
Other risk factors include smoking, genetics, and age. People in their 40s or 50s are at a higher 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 note, too, that mesothelioma can be present in people who have been exposed to asbestos without having worked with it directly. This is referred to as indirect or secondary asbestos exposure, and is just as harmful as direct asbestos exposure.
Smoking increases the risk of developing mesothelioma since it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos litigation and have a longer period of exposure than women. Also, men are more likely to live with someone who has had asbestos exposure and bring asbestos fibers that have escaped home on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos on their clothing.
Diagnosis
It is difficult to recognize mesothelioma since its symptoms are frequently similar to other illnesses. This can lead to victims being misdiagnosed.
The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient which includes asbestos exposure. Doctors can also request an X-ray chest or CT scan to detect lumps and other abnormalities, and also to look for evidence of past asbestos exposure such as plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).
Other diagnostic tests include a magnetic resonance imaging, or MRI test, which makes use of radio waves and magnets to produce a series of precise images of inside the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. During a surgical biopsy, doctors remove a small piece of tissue from the peritoneum or pleura for further testing. A pathologist can then examine the tissue under an magnifying glass to determine if it contains cancerous cells.
The type of mesothelial cell involved as well as the benign or malignant nature of these cells as well as the location the cancer, its type and the stage of the tumour, are used to categorize the disease. Certain types of mesothelioma may be more likely to grow or spread, so it is important to have a clear diagnosis so doctors can treat the disease before it becomes out of control.
Doctors may also conduct tests in the lab on tumors to determine particular proteins, genes and 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 diagnosis can be an incredibly frightening prospect. It is crucial to remember, however, that cancer can be treated, especially at its early stages. Many people with mesothelioma live for a long time without the disease spreading to other organs of their body.
Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are too small to see or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). As time passes the irritation can lead to the formation of scar tissues, which eventually lead to tumors.
The pleura is the area that surrounds the heart and lungs and also the abdomen. Mesothelium consists of cells that respond when exposed to asbestos legal. They cause inflammation of the tissue and cause it to become scarred. These changes can cause mesothelioma cancers.
A shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all signs of pleural Msothelioma. In rare cases cancer can spread to the tissues surrounding the reproductive organs as well as the heart.
A doctor will order biopsy if imaging scans show a potential mass in the lungs or stomach. During the procedure doctors remove a small amount of fluid or tumor to allow for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and help determine the best treatment option.
There are many types of treatment for mesothelioma including chemotherapy and surgery. Most doctors utilize the combination of these methods. Patients can also benefit by enrolling in a clinical trial of new mesothelioma therapies. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated the disease.
