Mesothelioma and Asbestos

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

The symptoms of these diseases might not show up for decades after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the outer lung lining, also known as the pleura. It is the most frequent mesothelioma that accounts for up between 70 and 79% of diagnosed cases. The condition can cause chest discomfort, shortness of breath and a feeling of weightiness.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, typically causes this kind of cancer. Once inhaled, these fibers are absorbed into the lung and cause irritation that leads to scarring and DNA mutations. Pleura covers both the chest cavity as well as the lungs, so irritations can also affect the heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma are chest pain and shortness of breath. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. People with this cancer have a history that includes asbestos exposure at work. The most prevalent jobs that expose people to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who were in the military are at higher risk due to the frequent use of asbestos in Navy vessels and Army bunkers.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at when they are diagnosed will assist their doctor in determining the most effective treatment plan for them. For example, patients with mesothelioma pleural stage three or four have a worse prognosis than patients with a lower stage. Stage four mesothelioma often spreads to the diaphragm, the liver or even a person's heart. This can make it more difficult to treat and increases the chance of complications for patients.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum - a membrane that lines the abdominal cavity and organs such as the intestines and the liver. Similar to pleural mesothelioma, asbestos exposure is the primary cause of peritoneal msothelioma. There are only 300-500 cases diagnosed annually this is less than pleural asbestosis.

Like pleural mesothelioma, the symptoms can take years to show. Most patients experience abdominal pain and abdominal swelling. This kind of mesothelioma can cause nausea, weight loss, and fever. Many of these symptoms can be mistaken for gastrointestinal problems which can lead to a mistaken diagnosis.

Typically, doctors can identify mesothelioma by conducting an extensive health history and physical exam. Imaging tests like X-rays and CT scans are a way to identify mesothelioma. These tests can detect tumors and other signs of cancer that are not visible on X-rays.

These test results 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 tumor has spread.

The most important mesothelioma risk factor is exposure to asbestos. People who have worked in professions which require asbestos law, such as plumbing, manufacturing, electrical work, or construction, are at a higher risk of developing the disease. Even if an individual is not employed in any of these areas they could be exposed to asbestos lawsuit through family members or other sources. Anyone who suspects that they are at risk should talk to an expert. A mesothelioma specialist can help those with a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma accounting for up to 80 percent of cases. Exposure to asbestos can happen as a result of work, military service, or through living with a person who works with asbestos or used to do the same. Asbestos particles can be breathed in by those who are exposed to asbestos claim. These irritate the linings and can cause cancerous cells to form in the mesothelium. Mesothelioma can take 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 and 50s are more likely develop mesothelioma than those who are younger or older. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind that mesothelioma may occur in those who have been exposed to asbestos, but without having worked with it directly. This is called secondary or indirect exposure to asbestos and it can be just as dangerous as direct exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium and makes it more susceptible to asbestos. In addition, mesothelioma may be caused by certain illnesses, such as pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. This is because men are more likely to work with asbestos and experience a more exposure than women. Also, men are more likely to live with someone who was exposed to asbestos case and bring Asbestos Case; Www.Daedo.Kr, fibers that have escaped home on their clothes. Women are less likely to be exposed to asbestos, and they are less likely to carry asbestos on their clothes.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being frequently similar to other illnesses. This can lead to victims being incorrectly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take down a patient's medical history including asbestos exposure. Doctors can also request an X-ray chest or CT scan to look for lumps and other abnormalities, as well as evidence of past asbestos exposure like pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI, test that uses radio waves and magnets to create detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is to perform an operation called a biopsy. When a biopsy is performed doctors will remove a small piece of tissue from pleura or the peritoneum, to be further examined. A pathologist then examines the tissue under an magnifying glass to determine if it is a 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 classify the disease. Certain types of mesothelioma are at a higher chance of metastasizing or spreading and it's crucial to determine the type of mesothelioma so that doctors can treat it prior to it becoming out-of-control.

Doctors may also conduct laboratory tests on tumors to determine specific proteins, genes or other elements that will help them identify cancer characteristics and determine the best treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnosis is a frightening prospect. It is crucial to remember, however, that cancer can be treated, particularly in its initial stages. Many patients with mesothelioma survive for a long time with the disease, without spreading to other areas of their body.

Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are tiny enough to be felt or viewed by naked eyes are able to become airborne, causing irritation to the lining of the lung (pleura). Over time, the irritation causes the formation of scar tissue, which can cause changes in the structure of cells which eventually lead to tumors.

The pleura covers the lungs and the heart and also the abdomen. Mesothelium is made up of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. These changes can result in malignant mesothelioma tumors.

A shortness of breath, chest pain or fluid accumulation on the lungs are all signs of the pleural mesothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.

If scans of imaging reveal an area of concern in the stomach or lungs, a doctor will order biopsies. During the procedure, doctors will remove small amounts of the fluid or tumor for laboratory tests. The results can confirm a mesothelioma diagnosis, and determine the most effective treatment plan.

There are many types of treatment for mesothelioma, including surgery and chemotherapy. Most doctors utilize the combination of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma treatments. To learn more about the trials, patients should speak to mesothelioma experts who have had experience treating the disease.
