Mesothelioma and Asbestos

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

It could take a long time for symptoms to appear after exposure to asbestos. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung the lining (pleura). It is the most prevalent mesothelioma form and is responsible for 70 to 79% all diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of weightiness.

Exposure to asbestos, a group of minerals comprised of microscopic fibers causes this kind of cancer. Once inhaled, the fibers are absorbed into the lung and cause irritation which results in scarring and DNA mutations. Pleura surrounds 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 common symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Patients may have coughing problems, trouble breathing, or chest tightness. People with this cancer often have previous exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most prevalent occupations that put people at high chance of developing pleural mesothelioma. Individuals who have been in the military could be at a higher risk because of the extensive asbestos use in Navy vessels and army bunkers.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage the patient is in at the time of diagnosis will help determine the treatment plan they should follow. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis than those in a lower stage. Stage four mesothelioma can develop into the liver, heart, or diaphragm. This makes the cancer more difficult to treat, and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma is found in the peritoneum - an elongated membrane that covers the abdominal cavity and organs such as the intestines and liver. As with pleural mesothelioma exposure to asbestos lawyer is the cause of peritoneal mesothelioma. It is estimated that only 300-500 cases are diagnosed each year, which is less than pleural asbestosis.

Like pleural mesothelioma, the symptoms can take a long time to manifest. Patients usually suffer from abdominal pain and could also experience a mass in their abdomen. Symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms are similar to symptoms of digestive issues, which could lead to misdiagnosis.

Doctors can identify mesothelioma by examining the patient's medical history and conducting a physical exam. They can also use imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can reveal tumors as well as other signs of cancer that aren't evident on X-rays.

These test results allow doctors to diagnose mesothelioma, identify the stage of the disease and suggest treatment options. The stage of the disease is determined based on the cell type and whether or not the cancer has spread to other regions of the body.

The most significant mesothelioma risk factor is asbestos exposure. People who have worked in professions that require asbestos, like plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if someone isn't employed in any of these areas, he or she can be exposed to asbestos to asbestos through family members and other sources. Anyone who suspects that they are at risk should talk to an expert. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in finding out more about the risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos can happen due to work, military service, or by living with someone who is exposed to asbestos or has previously done such. Asbestos particles can be inhaled by those who are exposed to asbestos. These irritate the linings and cause cancerous cells to form in the mesothelium. After exposure to asbestos mesothelioma can occur between 15 and 60 years old.

Other risk factors include smoking, genetics, and age. The people in their 40s or 50s are at greater chance of developing mesothelioma to people who are younger or more. Mesothelioma can take between 20 and 60 years to show signs of cancer after the first exposure. It is important to note, too, that mesothelioma may occur in those who have been exposed to asbestos without having directly worked with it. This is referred to as indirect or secondary exposure to asbestos, and it is just as harmful as direct exposure.

Smoking increases the chance of mesothelioma since it damages mesothelium. It can also make it more vulnerable. Additionally, mesothelioma can be caused by certain illnesses, such as pneumonia and asbestosis. It is also important to remember that mesothelioma occurs more frequently in males than females. Men are more likely than women to have been exposed to asbestos for a longer time and work with it. Men are also more likely to live with someone who has worked with asbestos and carry asbestos fibers from their workplace on their clothes. Women tend to have less contact with asbestos and don't typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to recognize because the symptoms often resemble other diseases. This is why patients are often misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical history, including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray 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 an echocardiogram, which examines the heart and blood vessels, and a magnetic resonance imaging, also known as MRI test, which uses radio waves and magnets to create precise images of the inside of the body. Another way for doctors to detect mesothelioma is through a surgical biopsy. During a surgical biopsy, doctors remove a small piece of tissue from the peritoneum or pleura for further analysis. A pathologist is then able to look at the tissue under microscopes to determine whether it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cell involved, whether those cells are malignant or benign, and the location of the tumor, its type, and the stage of the cancer. Some types of mesothelioma have an increased chance of metastasizing or spreading and it's crucial to get a definitive diagnosis so that doctors can treat it prior to it becoming out-of-control.

Doctors may also conduct tests in the lab on tumors to determine specific proteins, genes and other factors which can help them identify the cancer's characteristics and plan treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. However, it is important to keep in mind that the cancer is treatable, particularly in its earlier stages. Many patients with mesothelioma survive for many years without the disease spreading to other parts of their body.

Exposure to asbestos lawsuit can trigger mesothelioma in a number of ways. Asbestos fibers, which are too small to see or feel by the naked eye can be airborne and cause irritation to the lung's lining (pleura). In time, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura surrounds the heart and lungs and the abdomen. Mesothelium consists of cells that react to exposure to asbestos which causes it to become inflamed and develop scar tissue. These changes can cause mesothelioma cancers.

The signs of pleural mesothelioma can include shortness of breath, chest pain or the accumulation of fluid on the lung (pleural effusion). In rare instances, cancer can spread into the tissues surrounding the reproductive organs and heart.

If imaging scans show an area of concern in the lungs or stomach doctors will recommend biopsies. The procedure involves the removal of some of the liquid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are many types of treatment for mesothelioma, such as chemotherapy and surgery. Most doctors utilize an amalgamation of these techniques. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial to patients. To find out more, patients should consult mesothelioma specialists who have experience treating the condition.
