Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining or pleura. It is the most prevalent mesothelioma type, accounting for up 70% to 79% of all diagnosed cases. Patients with this disease suffer from chest pain and shortness of breath and may experience the sensation of weight in the chest.

This kind of cancer is typically caused through exposure to asbestos, which is a cluster of minerals composed of microscopic fibers. These fibers, when inhaled can cause irritation and DNA mutations. The pleura covers the lungs and chest cavity This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural mesothelioma include chest pain and shortness of breath. 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. Construction, manufacturing and shipbuilding are the most frequent occupations that put people at high chance of developing pleural mesothelioma. People who were in the military are at a greater risk due to the extensive use asbestos in Navy vessels 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 has when they are diagnosed will assist their doctor in determining the most effective treatment plan for them. Patients who have pleural mesothelioma which is in stage three or stage four will suffer a more negative prognosis than those who are in a less advanced stage. Mesothelioma in stage four is usually spread to the liver, diaphragm or even the heart of a patient. This makes it more difficult to treat and raises the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum - it is a membrane that lines the abdominal cavity as well as organs such as the liver and intestines. Similar to pleural mesothelioma and peritoneal mesothelioma is caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma, with just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take several years to show. Most patients experience abdominal pain and a mass in the abdomen. This kind of mesothelioma can cause nausea, weight loss and fever. Many of these symptoms are similar to symptoms of digestive problems, which can lead to confusion in diagnosis.

Typically, doctors can identify mesothelioma by conducting a thorough health history and physical examination. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can reveal tumors and other cancer signs which aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the kind of cell and if the cancer has spread.

The most important mesothelioma risk factor is exposure to asbestos. People who have been in occupations that require asbestos, such as plumbing manufacturing, electrical work, or construction, are at a higher risk of developing the disease. Even if they do not work in these areas they could be exposed to asbestos lawyer through relatives or other sources. This is why anyone who is concerned that they might be at risk should talk to an expert. If they have a history of asbestos case exposure and mesothelioma is a concern, a specialist will assist them in finding out more about their risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos can occur due to work, military service or through living with a person who works with asbestos or has previously done the same. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. These particles can cause irritation to the linings and cause cancerous cells to form in the mesothelium. After exposure to asbestos claim mesothelioma can develop between 15 and 60 years.

Other risk factors include smoking, genetics, and the advancing 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 before it manifests cancer symptoms after the first exposure. It is important to keep in mind that mesothelioma can be present in people who have been exposed to asbestos, but without having directly worked with it. This is called secondary or indirect exposure to asbestos. It could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma developing, because it damages the mesothelium. It also makes it more prone to. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. It is also important to note that mesothelioma is more prevalent in males than females. This is because men are more likely to work with asbestos and have an extended period of exposure than women. Additionally, men are more likely to live with someone who has worked with asbestos and carry stray asbestos fibers home on their clothes. Women tend to be less in contact with asbestos, and they don't usually carry asbestos case; full report, on their clothes.

Diagnosis

Mesothelioma is difficult to recognize because the symptoms can be similar to other conditions. 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 down a patient's medical history which includes asbestos exposure. Doctors can also request a chest X-ray or CT scan to check for lumps and other abnormalities, as well as evidence of previous asbestos exposure such as plaques in the pleura (thickened pleura with calcium deposits) and the formation of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include a magnetic resonance image, or MRI test, that uses radio waves and magnets to create a series detailed images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform the procedure of a surgical biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the pleura or peritoneum for further testing. A pathologist can look at the tissue under microscopes to determine whether it has cancerous cells.

Mesothelioma is classified based on the type of mesothelial cell involved, whether the cells are benign or malignant, and the location of the tumor, its type, and the stage of the tumor. Some types of mesothelioma are more likely to spread or metastasize which is why it is crucial to get a definite diagnosis to ensure that doctors are able to treat the disease before it becomes out of control.

Doctors can also run tests in the lab on a tumor to find particular proteins, genes, or other factors 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 frightening. It is important to keep in mind that cancer can be treated, especially at its early stages. Many patients with mesothelioma survive for many years with the disease, without spreading to other areas of their body.

Asbestos exposure can cause mesothelioma through many mechanisms. Asbestos fibers, too small to detect or feel through the naked eye, can become airborne and irritate the lining of the lungs (pleura). As time passes irritation can lead to formation of scar tissue which can cause changes in the structure of cells that eventually develop into tumors.

The pleura is the area that surrounds the lungs and heart, as well as the abdomen. Mesothelium is composed of cells that react to asbestos which causes it to become inflamed and form scar tissue. These changes eventually lead to malignant mesothelioma tumours.

Breathing problems, chest pain or fluid accumulation on the lungs are all symptoms of the pleural Msothelioma. In rare cases, cancer can spread into the tissues around the reproductive organs as well as the heart.

If imaging scans show a possible mass in the stomach or lungs, a doctor will order a biopsies. During the procedure, doctors remove tiny amounts of fluid or tumor for lab testing. The results will confirm a mesothelioma diagnosis and determine the best treatment plan.

There are many types of treatment for mesothelioma, including surgery and chemotherapy. The majority of doctors employ a combination of these treatments. Enrolling in clinical trials of mesothelioma treatments that are new could be beneficial for patients. To find out more, patients should speak with mesothelioma specialists who have experience treating the condition.
