Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma occurs in the lung's outer lining also known as pleura. It is the most common form of mesothelioma and accounts for 70% to 79% of diagnosed cases. This condition causes chest pain, shortness of breathe and a feeling of heaviness.

This type of cancer is typically caused by exposure to asbestos which is a collection of minerals that are made up of microscopic fibres. The fibers, when inhaled, cause irritation and DNA mutations. The pleura covers the lungs and chest cavity, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

The most frequent symptoms of pleural melanoma are chest discomfort and shortness of breath. Patients may also suffer from chest tightness and coughing, or breathing difficulties. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. The most prevalent jobs that expose people to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who have worked in the military are at an especially high risk because of the extensive asbestos usage in Navy ships and army bunkers.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient is in at diagnosis will help their doctor determine the most appropriate treatment plan for them. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a worse prognosis than patients with lower stages. Stage four mesothelioma often spreads to the diaphragm, liver and/or a person's heart. This can make it more difficult to treat and raises the risk of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum - a membrane that lines the abdominal cavity as well as organs such as the intestines and the liver. Similar to pleural mesothelioma, asbestos exposure is the primary cause of peritoneal mesothelioma. The disease is less prevalent than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Patients typically suffer from abdominal pain and may have a mass in their abdomen. The symptoms of this type of mesothelioma can also include nausea, weight loss and fever. Many of these symptoms are similar to symptoms of gastrointestinal issues, which can cause confusion in diagnosis.

The doctors can detect mesothelioma through looking over the medical history of the patient and performing a physical exam. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can detect tumors and other signs of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma, determine the stage of the disease and suggest treatment options. The staging is determined by the type of cell and whether or the cancer has spread to other areas of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have worked in asbestos-containing jobs, such as electrical or plumbing work or in manufacturing and construction, are more likely to develop the disease. Even if a person is not employed in one of these areas they could be exposed to asbestos through family members or other sources. Anyone who believes they may be at risk should talk to an expert. A mesothelioma expert can help those who have had a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the main risk factor for mesothelioma. It accounts for up to the 80% of cases. Exposure to asbestos may occur due to work, military service, or by living with a person who is exposed to asbestos or was previously exposed to doing the same. baldwin city asbestos law firm particles can be inhaled by people who are exposed to asbestos. They can cause irritation to the linings of the abdomen and cause cancerous cells to form in the mesothelium. After exposure to asbestos, mesothelioma may develop between 15 and 60 years old.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or more senior. Mesothelioma can take between 20 and 60 years to manifest cancer symptoms after the first exposure. It is important to note that mesothelioma can develop in those who have been exposed to asbestos without having directly worked with it. This is called indirect or secondary exposure to niagara falls asbestos lawsuit and it could be as hazardous as direct exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium and makes it more vulnerable to asbestos. Furthermore, mesothelioma is caused by certain illnesses, such as pneumonia and asbestosis. It is also important to know that mesothelioma is more prevalent for men than women. This is because men are more likely to work with asbestos and experience a an extended period of exposure than women. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos fibers on their clothing. Women are less likely to come into exposure to asbestos and don't typically carry asbestos on their clothing.

Diagnosis

Mesothelioma is difficult to recognize because the symptoms can be similar to other diseases. This could lead to patients being misdiagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history, including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart, and a magnetic resonance imaging, or MRI, test, which uses radio waves and magnets to create precise images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform a surgical biopsy. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist then examines the tissue with a magnifying glass to determine whether it contains cancerous cells.

Mesothelioma is classified based on the type of mesothelial cell involved, whether those cells are benign or malignant and also the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma are at greater chance of metastasizing or spreading, so it's important to get a definitive diagnosis to ensure that the doctors can treat it before it gets out-of-control.

Doctors can also run tests in the lab on a tumor to identify specific proteins, genes or other elements which can help them identify the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. It is crucial to remember, however, that cancer can be treated, especially at its early stages. A lot of people suffering from mesothelioma endure the disease for a long time, without expanding.

Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibres, too small to be felt or viewed with the naked eyes, can become airborne, causing irritation to the lung's lining (pleura). Over time the irritation can lead to the formation of scar tissues and eventually tumors.

The Pleura is a protective layer that protects the abdomen, heart, and lungs. Mesothelium is made up of cells that react to exposure to asbestos and cause it to enflame and create scar tissue. These changes can cause mesothelioma cancers.

Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all symptoms of the pleural msothelioma. In rare instances the cancer may be spread to the tissues around the heart and reproductive organs.

If imaging scans show a possible mass in the lungs or stomach the doctor will request a biopsies. During the procedure, doctors will remove small amounts of the tumor or fluid for lab tests. The results will confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

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