Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of thin, long fibres. Workers who are exposed to asbestos regularly are at risk of developing mesothelioma as well as other types of lung diseases.

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

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that affects the outer lung liner (pleura). It is the most prevalent mesothelioma form and accounts for 70% to 79% of all diagnosed cases. Patients suffering from this condition feel chest pain and breathlessness and may also feel an ache or heaviness in the chest.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, typically causes this kind of cancer. These fibers, when inhaled cause irritation and DNA mutations. The pleura covers the chest cavity and lungs, so these irritations can affect both the lungs and the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Some patients have coughing problems, trouble breathing or chest tightness. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of pleural mesothelioma include 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 bunkers in the Army.

The most common staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that a patient is at when they are diagnosed will aid their doctor in determining the most appropriate treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a less favorable outlook than those in a less advanced stage. Stage four mesothelioma is often spread to the diaphragm, the liver or even the heart of a patient. This makes the cancer 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 it develops in a membrane that surrounds the abdominal cavity, including organs like the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. It is estimated that only 300-500 cases are diagnosed annually, which is less than pleural asbestosis.

As with pleural mesothelioma symptoms may take years to appear. Most patients suffer from abdominal pain and an abdominal mass. The symptoms of this kind of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as gastrointestinal issues, leading to a false diagnosis.

Doctors can identify mesothelioma by looking over the medical history of the patient and conducting a physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal cancerous tumors or other signs of cancer that aren't visible on X-rays.

These test results enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatments. The staging is determined by the type of cells and whether or the cancer has spread to other parts of the body.

The most important mesothelioma risk factor is exposure to asbestos. People who have been exposed to asbestos in jobs, such as electrical or plumbing work, or in construction, manufacturing and manufacturing are more likely to develop the disease. However, even if people aren't employed in these areas they could be exposed to asbestos attorney through family members or through other sources. Anyone who believes they may be at risk should talk to a doctor. If they have any history of exposure to asbestos lawyer and mesothelioma is a concern, a specialist will help them find out more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma making up as much as 80 percent of all cases. Exposure to asbestos can happen due to military service, work, or living with people who have worked with asbestos legal - here.,. Asbestos particles can be breathed in by those who are exposed to it. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. After asbestos exposure mesothelioma can be diagnosed between 15 and 60 years.

Other risk factors include smoking, genetics, and age. People in their 40s or 50s are at a higher risk of developing mesothelioma as compared to people who are younger or more. Mesothelioma can take between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to remember that mesothelioma may be present in those who have been exposed to asbestos without having worked with it directly. This is known as indirect or secondary exposure to asbestos. It can be just as dangerous as direct exposure.

Smoking can increase the likelihood of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more prone to asbestos. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to know that mesothelioma is more common for men than women. This is due to men being 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 been exposed to asbestos, and to carry asbestos settlement fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos around on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms are often similar to other diseases. Because of this, victims are sometimes mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient, including asbestos exposure. Doctors can also order an X-ray chest or CT scan to detect 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 formation of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram which examines the heart and blood vessels, and a magnetic resonance imaging, or MRI test, which makes use of magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is yet another method doctors use to diagnose mesothelioma. When a biopsy is performed doctors will remove a small piece of tissue from pleura or the peritoneum, to be examined further. A pathologist then examines the tissue with a magnifying lens to determine whether it contains cancerous cells.

The type of mesothelial cell involved, the malignant or benign nature of these cells and the location, type and stage of the tumour, are used to categorize the disease. Some types of mesothelioma have greater chance of metastasizing or spreading therefore it is essential to determine the type of mesothelioma to ensure that the doctors can treat it before it gets out-of-control.

Doctors may also conduct laboratory tests on a tumor to identify specific genes, proteins, or other factors which can help them identify the cancer's characteristics and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma can be frightening. But, it is crucial to remember that the cancer can be treated, particularly in its earlier stages. A lot of people suffering from mesothelioma live with the disease for many years without it expanding.

Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibres, too small to be felt or observed by naked eyes can be airborne and irritate the lining of the lung (pleura). Over time the irritation causes the formation of scar tissue and eventually tumors.

The pleura is a protective covering that protects the abdomen, heart, and lungs. Mesothelium consists of cells that react to exposure to asbestos, causing it to inflame and develop scar tissue. These changes eventually lead to malignant mesothelioma tumours.

The signs of pleural mesothelioma can include breathlessness, chest pain or an accumulation of fluid in the lung (pleural effusion). In rare instances cancer can spread to the tissues surrounding the reproductive organs as well as the heart.

If imaging scans reveal an area of concern in the lungs or stomach the doctor will request a biopsies. In the course of the procedure, doctors remove some of the fluid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment plan.

There are a variety of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize a combination of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma therapies. To learn more about the trials, patients should speak with mesothelioma experts who have experience treating the condition.
