Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally forms in the form of long, thin fibers. Workers who are exposed to asbestos settlement on a regular basis are at risk of developing mesothelioma as well as other lung diseases.

The symptoms of these diseases may not manifest for years after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, or the pleura. It is the most common type of mesothelioma, making up between 70 and 79% of all diagnosed cases. Patients with this disease feel chest pain and shortness of breath and may experience a sensation of heaviness in the chest.

This type of cancer often caused by exposure to asbestos, which is a collection of minerals made up of microscopic fibres. These fibers, when inhaled can cause irritation and DNA mutations. The pleura surrounds the chest cavity and lungs This means that these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Patients may also experience difficulty breathing, or chest tightness. People with this cancer often have a history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are among the most prevalent occupations which put people at risk risk of developing pleural mesothelioma. People who have worked in the military could be at a higher risk because of the extensive asbestos use in Navy vessels and bunkers for the army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used to treat pleural adenocarcinoma. The stage a patient is in at the time of diagnosis can help determine what treatment plan they should follow. For example, patients with a pleural mesothelioma in stage three or four have a poorer prognosis than those in a lower stage. Stage four mesothelioma often spreads to the liver, diaphragm or even a person's heart. This can make it more difficult to treat and raises the risk of complications for patients.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma is found in the peritoneum -- a membrane that lines the abdominal cavity and organs such as the liver and intestines. Similar to pleural mesothelioma, asbestos exposure is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed annually which is lower than pleural asbestosis.

As with pleural mesothelioma symptoms may take years to appear. Patients usually suffer from abdominal pain and could also experience a mass in their abdomen. This mesothelioma type can also cause nausea, weight loss and fever. Many of these symptoms can be misinterpreted as digestive issues and can lead to a false diagnosis.

Generally, doctors can find mesothelioma through an extensive health history and physical examination. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can reveal cancerous tumors or other indications of cancer that aren't apparent on an X-ray.

These test results allow doctors to diagnose mesothelioma, identify the stage 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 worked in jobs that involve asbestos, such as plumbing or manufacturing, electrical work, or construction, are at increased risk of developing the disease. Even if a person is not employed in any of these areas however, they may be exposed to asbestos through family members or other sources. Anyone who thinks they're at risk should speak with a doctor. A mesothelioma specialist can help those who have a previous history of asbestos to find out more about their risk.

Risk Factors

asbestos legal is the primary risk factor for mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos may occur through work, military service, or by living with someone who is exposed to asbestos or has previously done such. Asbestos particles can be breathed in by those who are exposed to it. The particles cause irritation to the linings, causing cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s or 50s are at greater chance of developing mesothelioma to people who are younger or more. It takes mesothelioma between 20 and 60 years to show signs of cancer after the first exposure. It is also important to note that mesothelioma is a possibility in people who have been exposed to asbestos but didn't deal with it directly. This is known as secondary or indirect asbestos exposure, and is as dangerous as direct asbestos exposure.

Smoking increases the chance of mesothelioma because it damages the mesothelium. It also makes it more susceptible. 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 settlement for longer periods of time and to work with it. Additionally, men are more likely to live with someone who had asbestos lawyer exposure and bring asbestos fibers from their workplace on their clothes. Women are less likely to come into exposure to asbestos and rarely carry asbestos around on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to identify because the symptoms can be similar to other conditions. This can result in patients being misdiagnosed.

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 as well as evidence of previous asbestos exposure such as plaques on the pleura (thickened pleura with calcium deposits) and the accumulation 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 magnets and radio waves to make a series of detailed images of the interior of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. When a biopsy is performed, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be tested further. A pathologist will then look at the tissue under a magnifying glass to determine if it contains cancerous cells.

The type of mesothelial cells involved, the malignant or benign nature of those cells as well as the location, type and stage of the cancer are used to categorize the disease. Certain types of mesothelioma are more likely to develop metastasis 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 laboratory tests on tumors in order to determine specific proteins, genes, or other factors which can help them describe cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A mesothelioma diagnose can be terrifying. It is important to remember that cancer can be treated, especially at its early stages. Many mesothelioma patients live for many years without the disease spreading to other organs of their body.

Exposure to asbestos can trigger mesothelioma via various mechanisms. asbestos settlement fibres, small enough to not be felt or observed by naked eyes, can become airborne, irritating the lung's lining (pleura). As time passes the irritation can lead to the formation of scar tissue that eventually result in tumors.

The Pleura is a protective layer that covers the lungs, heart and abdomen. Mesothelium is composed of cells that react when exposed to asbestos attorney. They cause inflammation to the tissue and cause it to become scarred. These changes eventually lead to malignant mesothelioma tumours.

The symptoms of pleural mesothelioma are breathlessness and chest pain, or an accumulation of fluid in the lungs (pleural effusion). In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

A doctor will order biopsy if imaging scans show the possibility of a tumor in the lungs or stomach. During the procedure doctors remove small amounts of fluid or tumor for lab tests. The results will confirm a mesothelioma diagnosis, and indicate the most effective treatment plan.

There are many types of treatment for mesothelioma including surgery and chemotherapy. Most doctors rely on a combination of these methods. Participating in clinical trials of new mesothelioma treatment may also be beneficial for patients. To learn more, patients should speak with mesothelioma specialists who have had experience treating the disease.
