Mesothelioma and Asbestos
Asbestos is a naturally occurring mineral that is found in thin, long fibres. People who are exposed to asbestos are at risk of developing lung diseases such as mesothelioma.
It could take a long time for symptoms to show up after exposure to
asbestos settlement. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer that occurs in the lung's outer the lining (pleura). It is the most frequent mesothelioma that accounts for up 70 to 79% of diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling heavyness.
This type of cancer typically caused by exposure to asbestos, which is a cluster of minerals that are made up of microscopic fibres. When inhaled, these fibers are absorbed into the lung and cause irritation that leads to scarring and DNA mutations. Pleura is the lining of both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.
The most commonly reported symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Some patients may also experience chest tightness, coughing or difficulty breathing. Patients with this type of cancer typically have previous exposure to asbestos in the workplace. Construction, manufacturing, and shipbuilding are the most common occupations that put people at high danger of developing pleural melanoma. People who were in the military are at greater risk due the frequent use of asbestos in Navy vessels and bunkers for the Army.
The most common staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has when they are diagnosed will help their doctor determine the best treatment plan for them. Patients who have pleural mesothelioma which is in stage three or stage four will have a less favorable outlook than those who are in a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver or even the heart of a patient. This can make the cancer more difficult to treat and increase the chances of complications for the patient.
Peritoneal Mesothelioma
In contrast to pleural cancer, which is found in the lung's lining it develops in the membrane that covers the abdominal cavity, which includes organs such as the intestines and liver. Similar to pleural mesothelioma mesothelioma is caused by asbestos exposure. It is estimated that only 300-500 cases are diagnosed annually which is lower than the pleural asbestosis.
Like pleural mesothelioma, symptoms may take years to appear. Patients typically experience abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma could also include nausea, weight loss and fever. Many of these symptoms are similar to those experienced by gastrointestinal issues, which can result in confusion in diagnosis.
Doctors can identify mesothelioma by looking over the medical history of the patient and performing a physical examination. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can detect tumors as well as other signs of cancer that aren't visible on X-rays.
These test results allow doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the type of cell and whether the cancer has spread.
Asbestos exposure is the main risk factor. People who have been exposed to asbestos in occupations, like electrical or plumbing work or in manufacturing and construction are more likely to contract the disease. Even if an individual isn't employed in any of these areas, he or she can still be exposed to asbestos through family members and other sources. Anyone who believes they're at risk should talk to an expert. A mesothelioma specialist can assist those who have had a history with asbestos to learn 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 claim. Asbestos particles can be breathed in by those who are exposed to it. These irritate the linings and can cause cancerous cells to form in the mesothelium. After exposure to asbestos mesothelioma can develop between 15 and 60 year.
Other risk factors include smoking, genetics, and age. People in their 40s and 50s are more likely get mesothelioma than people younger or more senior. This is because mesothelioma usually lasts between 20 and 60 years from the initial exposure before the first signs of cancer appear. It is important to remember, too, that mesothelioma could develop in people who have been exposed to asbestos, but without having worked with it directly. This is referred to as secondary or indirect exposure to
Asbestos Case. It is just as harmful as direct exposure.
Smoking increases the risk of developing mesothelioma since it damages the mesothelium and makes it more susceptible to asbestos. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is because men are more likely to work with asbestos and have an extended period of exposure than women. Men are also more likely to live with someone who has worked with
asbestos attorney and carry asbestos fibers that have escaped home on their clothing. Women are less likely to be in contact with asbestos, and they don't usually bring asbestos home on their clothing.
Diagnosis
It is difficult to diagnose mesothelioma because its symptoms are frequently similar to other illnesses. Because of this, victims are often mistakenly diagnosed.
NYU Langone doctors will perform physical examinations and document the patient's medical background including asbestos exposure. Doctors may also order an X-ray of the chest or CT scan to look for lumps and other abnormalities, and also to look for evidence of asbestos exposure in the past like plaques on 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 an echocardiogram which examines the heart and blood vessels as well as a magnetic resonance imaging, or MRI test, which uses 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 to perform 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 examine the tissue under microscopes to determine whether it has cancerous cells.
Mesothelioma is classified according to the type of mesothelial cell involved, whether these cells are malignant or benign, and the location of the tumor, its type, and the stage of the tumor. Certain types of mesothelioma may be more likely to grow or spread and spread, therefore it is essential to get a definite diagnosis so that doctors can treat the disease before it becomes out of control.
Doctors may also conduct tests in the laboratory on tumors to determine specific genes, proteins, or other factors that can help them describe the cancer's characteristics and plan treatment. These results are referred to as staging.
Treatment
A diagnosis of mesothelioma can be frightening. However, it's important to remember that the cancer is treatable, especially in its early stages. Many mesothelioma patients live for a long time with the disease without it spreading to other parts of their body.
Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are too small to see or feel with the naked eye, can be airborne and cause irritation to the lung's lining (pleura). Over time, the irritation causes the formation of scar tissue which causes changes in the structure of cells that can eventually grow into tumors.
The Pleura is a protective layer that covers the lungs, heart and abdomen. Mesothelium consists of cells that react to exposure to asbestos, causing it to inflame and form scar tissue. Overtime, these changes lead to the development of malignant mesothelioma tumors.
The symptoms of pleural mesothelioma are shortness of breath and chest pain, or the accumulation of fluid on the lung (pleural effusion). In rare cases cancer may spread to the tissues surrounding the reproductive organs and the heart.
If imaging scans reveal a possible mass in the stomach or lungs doctors will recommend a biopsies. During the procedure doctors remove some of the liquid or tumor for lab tests. The results will confirm the diagnosis of mesothelioma and provide the best treatment plan.
There are several types of mesothelioma treatment, including surgery, chemotherapy and immunotherapy. Most doctors use the combination of these treatments. Patients could also benefit from participating in a clinical study of new mesothelioma treatment. Patients can learn more by consulting a mesothelioma specialist who has treated the disease.
