Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally occurs in the form of long, thin fibers. Workers who are regularly exposed to asbestos may develop lung diseases such as mesothelioma.

It can take years before symptoms begin to manifest after asbestos exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung lining (pleura). It is the most prevalent type of mesothelioma, making up 70 to 79% of all diagnosed cases. People with this condition experience pain in the chest and breath shortness and may experience a sensation of heaviness in the chest.

This type of cancer is usually caused by exposure to asbestos legal, which is a collection of minerals comprised of microscopic fibres. When inhaled, these fibers stick inside the lungs and cause irritation that results in scarring and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Some patients may also feel tightness in their chest and coughing, or breathing difficulties. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. Manufacturing, construction, and shipbuilding are the most frequent occupations that put people at a high risk of developing pleural mesothelioma. People who have worked in the military may be at a higher risk due to the widespread asbestos lawyer usage in Navy ships and army bunkers.

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

Peritoneal Mesothelioma

Contrary to pleural cancer which is found in the lining of the lung the peritoneal cancer is a result of a membrane that covers the abdominal cavity, which includes organs such as the liver and intestines. Similar to pleural mesothelioma mesothelioma is triggered by asbestos exposure. Only 300-500 cases are diagnosed annually this is less than pleural asbestosis.

Like pleural mesothelioma, the symptoms may take years to appear. The majority of patients experience abdominal pain and a mass in the abdomen. Symptoms of this type of mesothelioma could also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to those of digestive problems, which can lead to incorrect diagnosis.

Typically, doctors can identify mesothelioma after a thorough health history and physical exam. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can reveal tumors and other cancer signs which aren't evident on X-rays.

These tests enable doctors to identify mesothelioma, and determine the stage. They can also recommend treatment options. The stage of the disease is determined based on the type of cell and whether or whether the tumor has spread to other parts of the body.

The most significant mesothelioma risk factor is asbestos exposure. People who have worked in asbestos-related occupations, like plumbing or electrical work, or in construction and manufacturing are more likely to develop the disease. Even if a person does not work in one of these fields they could still be exposed through family members or other sources. Therefore, anyone who suspects they may be at risk should speak to an expert. A mesothelioma specialist can help those who have a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the main 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 works with asbestos or has previously done such. Asbestos particles can be breathed in by those who are exposed to asbestos lawyer. These particles can cause irritation to the linings of the abdomen, which causes cancerous cells to form in the mesothelium. After asbestos exposure mesothelioma is likely to develop between 15 and 60 years old.

Other risk factors include smoking, genetics and age. The people in their 40s or 50s are more at risk of developing mesothelioma compared to those younger or older. It is because mesothelioma generally lasts between 20 and 60 years after the initial exposure to asbestos compensation before cancer symptoms appear. It is important to keep in mind that mesothelioma could develop in people who have been exposed to asbestos case; click here to investigate, without having directly worked with it. This is referred to as secondary or indirect exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium, which makes it more prone to asbestos. Mesothelioma is also aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to note that mesothelioma is more common in males than females. This is due to the fact that men are more likely to be exposed to asbestos and endure a more exposure than women. Also, men are more likely to live with someone who has worked with asbestos and carry stray asbestos fibers home on their clothing. Women are less likely to come into contact with asbestos and don't typically carry asbestos home on their clothing.

Diagnosis

It is difficult to identify mesothelioma because its symptoms are often similar to other conditions. This can result in patients being misdiagnosed.

The first step to diagnose 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 may also order an X-ray chest or CT scan to check for lumps and other abnormalities as well as evidence of asbestos exposure in the past such as pleural plaques (thickened pleura with calcium deposits) and the accumulation 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, also known as MRI, test that uses magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura for further testing. A pathologist can examine the tissue under microscopes to determine whether it contains cancerous cells.

The type of mesothelial cells involved as well as the benign or malignant nature of those cells as well as the location and stage of the tumour, are used to categorize the disease. Certain mesothelioma types have an increased risk of metastasizing or spreading therefore it is essential to determine the type of mesothelioma so doctors can treat it prior to it becoming out-of-control.

Doctors can also perform tests in the laboratory on tumors in order to determine specific proteins, genes or other elements that can aid in describing cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is important to remember, however, that cancer can be treated, particularly in its initial stages. Many mesothelioma patients live for many years with the disease without it spreading to other areas of their body.

Exposure to asbestos may cause mesothelioma in a number of ways. Asbestos fibers, which are too small to detect or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). Over time, the irritation leads to the formation of scar tissues, which eventually lead to tumors.

The pleura is the area that surrounds the lungs and heart and also the abdomen. Mesothelium is made up of cells that react to exposure to asbestos, causing it to inflame and develop scar tissue. As time passes, these changes lead to the development of malignant mesothelioma tumors.

A shortness of breath, chest pain or fluid accumulation on the lungs are all indications of the pleural mesothelioma. In rare cases cancer may spread to the tissues that surround the reproductive organs and the heart.

If imaging scans show an underlying mass in the lungs or stomach doctors will recommend a biopsies. During the procedure, doctors take small amounts of the tumor or fluid for lab analysis. The results can confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. The majority of doctors use an amalgamation of these techniques. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial to patients. Patients can find out more by speaking with a mesothelioma doctor who has treated the condition.
