Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally occurs in the form of long, thin fibers. Workers who are exposed to asbestos regularly risk developing mesothelioma and other lung diseases of different types.

The symptoms of these diseases might not be evident for a long time after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the outer lung lining, also known as pleura. It is the most prevalent mesothelioma form and is responsible for 70 to 79% of diagnosed cases. The condition can cause chest discomfort, shortness of breath and a feeling heaviness.

Exposure to asbestos litigation, a group of minerals made of microscopic fibers, typically causes this type of cancer. The fibers, when inhaled, cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as 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 pain and shortness of breath. Patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this type of cancer have a past that includes asbestos exposure at work. The most prevalent jobs that expose workers to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. People who have served in the military may be at risk due to the widespread use of asbestos in Navy ships and bunkers for the army.

The most common staging system for pleural mysothelioma has been the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has at diagnosis will aid their doctor in determining the most appropriate treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or four will have a worse prognosis than those in a less advanced stage. Stage four mesothelioma often spreads to the diaphragm, liver or even a person's heart. This makes it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lung's lining the peritoneal cancer is a result of a membrane that surrounds the abdominal cavity, which includes organs like the liver and intestines. Similar to pleural mesothelioma and peritoneal mesothelioma is caused by asbestos exposure. There are only 300-500 cases diagnosed each year this is less than pleural asbestosis.

As with pleural asbestosis, symptoms can take a long time to manifest. Patients usually have abdominal pain, and could also experience a mass in their abdomen. Symptoms of this type of mesothelioma could also include nausea or weight loss, as well as fever. Many of these symptoms are similar to those experienced by gastrointestinal issues, which can lead to incorrect diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical exam. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can detect tumors and other cancer signs that aren't visible on X-rays.

These test results allow doctors to diagnose mesothelioma, identify the stage of the disease and suggest treatment options. The stage is determined by the kind of cell and if the cancer has spread.

Asbestos exposure is the biggest risk factor. People who have worked in jobs which require asbestos, like plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if a person does not work in one of these areas however, they may be exposed to asbestos to asbestos lawsuit through family members and other sources. For this reason, anyone who believes they could be at risk should speak to an expert. A mesothelioma specialist can assist those who have a previous history of asbestos litigation to find out more about their risk.

Risk Factors

Asbestos Legal is the main mesothelioma-related risk factor. It accounts for as much as 80percent of cases. Exposure to asbestos may occur through work, military service, or by living with someone who works with asbestos or used to do such. When exposed to asbestos, particles can be breathed into the lungs and abdomen. They can cause irritation to the linings of the abdomen and trigger cancerous cells to grow in the mesothelium. Following exposure to asbestos, mesothelioma may occur between 15 and 60 year.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely to develop mesothelioma than those who are younger or more senior. It is because mesothelioma generally takes 20 to 60 years from the initial exposure before the first signs of cancer appear. It is also important to note that mesothelioma is a possibility in people who were exposed to asbestos, but did not work with it directly. This is referred to as indirect or secondary asbestos exposure, and is just as harmful as direct asbestos exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It can also make it more vulnerable. Furthermore, mesothelioma is exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to know that mesothelioma occurs more frequently in males than females. This is because men are more likely to be exposed to asbestos and endure a a longer period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos lawsuit and to have asbestos fibers on their clothing. Women are less likely to be in contact with asbestos, and they are less likely to carry asbestos on their clothes.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being often similar to other diseases. This can result in patients being wrongly diagnosed.

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 may also request an CT scan or chest X-ray in order to look for lumps, abnormalities and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which makes use of radio waves and magnets in order to produce a series of precise images of inside the body. Another method doctors use to diagnose mesothelioma is to perform the procedure of a surgical biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist will then look at the tissue under a magnifying lens to determine if it contains cancerous cell.

The mesothelial type involved and the benign or malignant nature of these cells as well as the location and stage of the cancer are used to categorize the disease. Certain mesothelioma types have a higher risk of spreading or metastasizing and it's crucial to establish a clear diagnosis so doctors can treat it prior to it becoming out-of-control.

Doctors may also conduct tests in the laboratory on a tumor to identify specific proteins, genes and other factors that can help them describe the characteristics of the cancer and determine a treatment. These results are called staging.

Treatment

A mesothelioma diagnose can be terrifying. But, it is crucial to remember that the disease can be treated, particularly in its earlier stages. A lot of people suffering from mesothelioma endure the disease for a long time without spreading.

Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos fibers, which are too small to be felt or seen with the naked eyes can be airborne, causing irritation to the lung's lining (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 surrounds the lungs and heart and also the abdomen. Mesothelium consists of cells that react to exposure to asbestos and cause it to enflame and develop scar tissue. In time, these changes can result in the growth of malignant mesothelioma tumors.

Breathing problems, chest discomfort or fluid buildup on the lungs are all symptoms of the pleural msothelioma. In rare cases, cancer can spread into the tissues that surround the reproductive organs as well as the heart.

If scans of imaging reveal an area of concern in the stomach or lungs, a doctor will order biopsies. The procedure involves the removal of a small amount of fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. The majority of doctors employ the combination of these treatments. Patients could also benefit from enrolling in a clinical trial of new mesothelioma treatment. To find out more, patients should consult mesothelioma experts who have had experience treating the disease.
