Mesothelioma and Asbestos
Asbestos is a natural mineral that is found in thin, long fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases, such as mesothelioma.
Symptoms of these diseases may not show up for decades after exposure to asbestos. Different asbestos types may cause different symptoms.
Pleural Mesothelioma
Pleural mesothelioma is a cancer that occurs in the lung's outer lining (pleura). It is the most frequent mesothelioma type, accounting for up 70 to 79% of all diagnosed cases. Patients with this disease feel chest pain and breathlessness, and they may feel a sensation of heaviness in the chest.
This type of cancer is typically caused through exposure to
asbestos lawsuit, 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 results in scarring and DNA mutations. The pleura surrounds the chest cavity and lungs and therefore, these irritations could affect both the lungs as well as a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.
The most common symptoms of pleural melanoma are chest pain and shortness of breath. Some patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this cancer have a history that includes
asbestos litigation exposure at work. Construction, manufacturing and shipbuilding are the most prevalent occupations that put people at high risk of developing pleural mesothelioma. Individuals who have served in the military are at greater risk due to the widespread use of asbestos in Navy vessels and Army bunkers.
The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system for the pleural cancer. The stage a patient is in at the time of diagnosis can help determine the treatment plan they should follow. For instance, patients who have mesothelioma pleural stage three or four have a poorer prognosis than those in a lower stage. Stage four mesothelioma can spread to the liver, heart or diaphragm. This makes it more difficult to treat and increase the chance of complications for the patient.
Peritoneal Mesothelioma
Unlike pleural cancer, which forms in the lining of the lung it develops in the membrane that covers the abdominal cavity, including organs like the liver and intestines. As with pleural mesothelioma asbestos exposure is the reason for peritoneal msothelioma. The disease is less common than pleural mesothelioma, and only about 300-500 cases diagnosed each year.
Like pleural mesothelioma, the symptoms can take years to show. The majority of patients experience abdominal pain and abdominal swelling. This kind of mesothelioma can cause nausea, weight loss and fever. Many of these symptoms are similar to those of gastrointestinal issues, which can cause incorrect diagnosis.
Typically, doctors can identify mesothelioma after an exhaustive health history and physical examination. They can also utilize imaging tests like Xrays, 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.
The results of these tests allow doctors to diagnose mesothelioma, determine the stage and recommend treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.
The most important risk factor for mesothelioma is exposure to
asbestos case. People who have worked in asbestos-related professions, such as 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 they could still be exposed through family members or other sources. Anyone who thinks they are at risk should speak with an expert. A mesothelioma specialist can help those who have a history with asbestos to learn more about their risk.
Risk Factors
Asbestos exposure is the main risk factor for mesothelioma, making up as much as 80 percent of cases. Exposure to asbestos may occur due to work, military service or by living with a person who works with asbestos or used to do so. When exposed to asbestos, small particles are able to be inhaled into lungs and abdomen. These particles can cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to
asbestos lawyer.
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. It is because mesothelioma generally takes 20 to 60 years from the first exposure before symptoms of cancer begin to manifest. It is important to keep in mind, too, that mesothelioma could occur in people who have been exposed to asbestos, but without having directly worked with it. This is called indirect or secondary exposure to asbestos and it can be just as dangerous as direct exposure.
Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is due to men being more likely to be exposed to asbestos (

asbestos legal and bring asbestos fibers from their workplace on their clothes. Women tend to be less exposed to asbestos and don't typically carry asbestos on their clothes.
Diagnosis
Mesothelioma is difficult to diagnose because the symptoms are often similar to other conditions. This could lead to patients being misdiagnosed.
The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take notes on the medical history of a patient, including asbestos exposure. Doctors can also order an X-ray chest or CT scan to look for lumps and other abnormalities as well as evidence of asbestos exposure in the past like plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and the chest wall (known as the pleural effusion).
Other diagnostic tests include a magnetic resonance image, or MRI test, which uses radio waves and magnets to produce a series of precise images of the inside of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. During a surgery biopsy doctors will remove a small piece of tissue from pleura or the peritoneum to be further examined. A pathologist can examine the tissue under a microscope to see if it is contaminated with cancerous cells.
The type of mesothelial cells involved and the benign or malignant nature of these cells and the location the cancer, its type and the stage of the cancer are used to classify the disease. Certain mesothelioma types have greater risk of spreading or metastasizing, so it's important to determine the type of mesothelioma so that doctors can treat it before it becomes out-of-control.
Doctors can also perform tests in the lab on tumors to identify specific genes, proteins, or other factors which can help them describe cancer characteristics and plan treatment. These results are referred to as staging.
Treatment
A mesothelioma diagnosis is terrifying. It is important to keep in mind, however, that cancer can be treated, particularly in its initial stages. A lot of people suffering from mesothelioma live with the disease for a long time, without spreading.
Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibers, which are too small 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 leads to the formation of scar tissue and eventually tumors.
The pleura is a protective covering that surrounds the abdomen, heart, and lungs. Mesothelium is composed of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to become scarred. These changes can cause mesothelioma cancers.
A shortness of breath, chest discomfort or fluid buildup on the lungs are all indications of the pleural Msothelioma. In rare cases cancer may spread to the tissues around the reproductive organs as well as the heart.
If imaging scans reveal an area of concern in the stomach or lungs, a doctor will order a biopsies. In the course of the procedure, doctors remove small amounts of liquid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and provide the best treatment option.
There are several types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors rely on an amalgamation of these techniques. Patients may also benefit from taking part 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.
