Why Nobody Cares About Mesothelioma And Asbestos
Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in thin, long fibres. People who are exposed to asbestos may develop lung diseases, such as mesothelioma.

The symptoms of these diseases may not manifest for years after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining, or the pleura. It is the most common form of mesothelioma and is responsible for 70 to 79% of all diagnosed cases. People with this condition suffer from chest pain and breathlessness and may experience the sensation of weight in the chest.

This type of cancer is typically caused through exposure to asbestos, which is a grouping of minerals composed of microscopic fibers. The fibers, when inhaled cause irritation and DNA mutations. The pleura surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Patients may also experience coughing, difficulty breathing, or chest tightness. People with this cancer have a past that includes asbestos exposure at work. The most frequent jobs that expose people to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. People who have served in the military could be at risk due to the widespread use of asbestos in Navy vessels and bunkers for the army.

Evanston asbestos lawsuits staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that the patient is in at the time of diagnosis will help determine what treatment plan they should receive. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a poorer prognosis than those with a lower stage. Stage four mesothelioma may spread to the liver, heart or diaphragm. This can make the cancer more difficult to treat, and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, which forms in the lining of the lung, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, including organs like the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma can be caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to manifest. The majority of patients suffer from abdominal pain and an abdominal mass. This mesothelioma type can also cause nausea, weight loss and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a false diagnosis.

Generally, doctors can find mesothelioma through an extensive health history and physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can reveal tumors, as well as other indications of cancer that aren't visible on X-rays.


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

The most important risk factor for mesothelioma is asbestos exposure. People who have worked in jobs that require asbestos, like plumbing, manufacturing, electrical work, or construction, are at increased risk of developing the disease. Even if someone is not employed in one of these areas, he or she can still be exposed through family members or other sources. For this reason, anyone who is concerned that they might be at risk should talk to a doctor. If they have any history of exposure to asbestos or mesothelioma, a specialist can help them find out more about the risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos can happen through work, military service or by living with someone who is exposed to asbestos or has previously done the same. Asbestos particles can be inhaled by those who are exposed to asbestos. They can cause irritation to the linings of the abdomen and trigger cancerous cells to develop in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to note, too, that mesothelioma could be present in those who have been exposed to asbestos, but without having worked with it directly. This is known as indirect or secondary exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It can also make it more vulnerable. Furthermore, mesothelioma is caused by certain illnesses, such as asbestosis and pneumonia. It is also important to note that mesothelioma is more common for men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who been exposed to asbestos, and to carry asbestos fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos around on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to recognize because the symptoms often resemble other diseases. This can result in patients being misdiagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take note of the medical history of the patient including asbestos exposure. Doctors may also order an X-ray chest or CT scan to look for lumps or other abnormalities, as well as evidence of asbestos exposure in the past like plaques in the pleura (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 as well as a magnetic resonance imaging, also known as MRI test that uses magnets and radio waves to make a series of detailed images of the interior of the body. Another method doctors use to diagnose mesothelioma is through an operation called a biopsy. When a biopsy is performed doctors will remove a small part of tissue from the pleura or the peritoneum to be examined further. A pathologist can examine the tissue with a microscope to see if it has cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether those cells are benign or malignant and also the location of the tumor, its type, and the stage of the tumor. Some types of mesothelioma have greater risk of spreading or metastasizing therefore it is essential to establish a clear diagnosis so that doctors can treat it prior to it becoming out of control.

Doctors may also conduct tests in the laboratory on tumors in order to determine specific proteins, genes, or other factors which can aid in describing the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnose can be terrifying. However, it's important to remember that the cancer can be treated, particularly in its earlier stages. Many people with mesothelioma can live with the disease for a long time, without expanding.

Exposure to asbestos can trigger mesothelioma via many mechanisms. Asbestos fibers, which are too small to be able to see or feel by the naked eye can become airborne and cause irritation to the lung's lining (pleura). As time passes irritation leads to formation of scar tissue which causes changes in the structure of cells which eventually lead to tumors.

The pleura is the area that surrounds the lungs and the heart and the abdomen. Mesothelium consists of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. As time passes, these changes cause the development of malignant mesothelioma cancers.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all symptoms of the pleural Msothelioma. In rare instances cancer may spread to the tissues surrounding the reproductive organs and the heart.

If imaging scans reveal an underlying mass in the lungs or stomach the doctor will request biopsies. During the procedure, doctors remove tiny amounts of tumor or fluid for lab testing. The results can confirm the diagnosis of mesothelioma and indicate the most effective treatment plan.

There are several types of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. The majority of doctors employ the combination of these treatments. Patients may also benefit from participating in a clinical study of new mesothelioma treatment. To find out more, patients should speak to a mesothelioma specialist who has experience treating the condition.
