Mesothelioma and Asbestos

Asbestos is a mineral that occurs naturally in the form of long, thin fibers. People who are exposed to asbestos claim regularly are at risk of developing mesothelioma or other lung diseases.

It can take years for symptoms to show up after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that occurs in the outer lung the lining (pleura). It is the most prevalent mesothelioma type and is responsible for 70 to 79% all diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of heavyness.

This kind of cancer is often caused by exposure to asbestos which is a collection of minerals that are comprised of microscopic fibres. When inhaled, these fibers stick inside the lungs and cause irritation that results in scarring and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest discomfort and shortness of breath. Patients may also experience coughing, difficulty breathing or chest tightness. Patients with this cancer have a history of disease that includes asbestos exposure at work. Construction, manufacturing, and shipbuilding are the most frequent jobs that put people at a high danger of developing pleural melanoma. People who have served in the military are at risk due to the widespread use of asbestos in Navy vessels and army bunkers.

The TNM (tumors lymph nodes 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 what treatment plan they should follow. For instance, patients who have mesothelioma that is pleural in stage three or four have a worse prognosis than those in a lower stage. Stage four mesothelioma can be spread to the liver, heart, or diaphragm. This makes the cancer more difficult to treat, and increase the chance of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, 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 and peritoneal mesothelioma can be caused by asbestos claim exposure. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take a long time to manifest. Patients usually experience abdominal pain, and could also experience a mass in their abdomen. Symptoms of this type of mesothelioma may also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to symptoms of digestive issues, which could lead to confusion in diagnosis.

Generally speaking, doctors can detect mesothelioma after an exhaustive health history and physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can show tumors, as well as other indications of cancer that aren't visible on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also suggest treatment options. Staging is determined based on the type of cell and whether or whether the cancer has spread to other regions of the body.

Asbestos exposure is the main risk factor. People who have worked in professions which require asbestos, such as plumbing, manufacturing, electrical work or construction, are at a higher risk of developing the disease. However, even if people do not work in these fields they may be exposed to asbestos through relatives or other sources. This is why anyone who suspects they may be at risk should speak to an expert. A mesothelioma specialist can assist those who have a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It is responsible for as much as the 80% of cases. Exposure to asbestos can occur as a result of work, military service, or through living with a person who works with asbestos or used to do the same. When exposed to asbestos, the particles can be breathed into the abdomen and lungs. These particles irritate the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos lawyer.

Other risk factors include genetics, smoking and aging. People in their 40s and 50s are at a higher chance of developing mesothelioma to those younger or older. It takes mesothelioma between 20 and 60 years to manifest cancer symptoms after the first exposure. It is also important to know that mesothelioma can develop in people who have been exposed to asbestos but did not deal with it directly. This is referred to as secondary or indirect asbestos exposure. It can be as dangerous as direct asbestos exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more prone to. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in men than women. This is due to the fact that men are more likely to work with asbestos and experience a a longer period of exposure than women. Men are also more likely to have lived with someone who has been exposed to asbestos case, and to have asbestos-containing fibers on their clothing. Women are less likely to be in contact with asbestos, and don't typically bring asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms are often similar to other diseases. This can lead to victims being incorrectly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient, including asbestos exposure. Doctors can also request an X-ray chest or CT scan to check for lumps and other abnormalities as well as evidence of previous asbestos exposure such as pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels, and a magnetic resonance imaging, also known as MRI, test, which uses magnets and radio waves to make a series of precise images of the inside of the body. Another method doctors use to diagnose mesothelioma is through the procedure of a surgical biopsy. In a surgical biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be examined further. A pathologist can then examine the tissue under microscopes to determine whether it has cancerous cells.

The mesothelial type involved as well as the benign or malignant nature of these cells as well as the location, type and stage of the tumour, are used to classify the disease. Certain mesothelioma types have a higher risk of spreading or metastasizing, so it's important to get a definitive diagnosis so that doctors can treat it before it becomes out-of-control.

Doctors can also run tests in the laboratory on tumors to determine specific proteins, genes and other factors that can help them describe the characteristics of the cancer and determine a treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be frightening. But, it is crucial to remember that the disease is treatable, especially in its initial stages. Many patients with mesothelioma live with the disease for a long time, without expanding.

Exposure to Asbestos Case may cause mesothelioma in a number of ways. Asbestos fibers, which are small enough to not be felt or observed by naked eyes are able to become airborne, causing irritation to the lining of the lung (pleura). In time, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura is a protective covering that covers the lungs, heart and abdomen. Mesothelium consists of cells that react to exposure to asbestos which causes it to become inflamed and form scar tissue. These changes can eventually lead to malignant mesothelioma tumours.

The symptoms of pleural mesothelioma are breathing problems and chest pain, or a buildup of fluid in the lung (pleural effusion). In rare instances, the cancer can be spread to the tissues around the heart and reproductive organs.

If imaging scans show an area of concern in the stomach or lungs the doctor will request a biopsies. During the procedure, doctors remove a small sample of the fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. Most doctors utilize a combination of these methods. Patients could also benefit from taking part in a clinical trial of new mesothelioma treatment. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated the disease.
