Mesothelioma and Asbestos

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

The symptoms of these diseases may not show up for decades after exposure to asbestos. 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 suffer from 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. Once inhaled, these fibers cling to the lung and cause irritation which causes scarring and DNA mutations. The pleura covers 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.

Shortness of breath and chest pain are the most common symptoms. Some patients may also experience chest tightness or coughing. They may also experience difficulty breathing. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. The most prevalent jobs that expose workers to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who have worked in the military could be at an especially high risk due to the frequent asbestos law use in Navy ships and bunkers used by the army.

The most popular staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that the patient is in at the time of diagnosis can help determine what treatment plan they should receive. For example, patients with mesothelioma pleural stage three or four have a worse prognosis than those with a lower 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 increases the chance of complications for patients.

Peritoneal Mesothelioma

Contrary to pleural cancer that develops in the lung's lining it develops in the membrane that covers the abdominal cavity, including organs such as the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to manifest. Most patients suffer from abdominal pain and a mass in the abdomen. The symptoms of this type of mesothelioma may also include nausea or weight loss, as well as fever. Many of these symptoms could be mistaken for gastrointestinal problems which can lead to a mistaken diagnosis.

Typically, doctors can identify mesothelioma by conducting an exhaustive medical history and physical exam. They can also utilize imaging tests like Xrays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors and other signs of cancer that are not visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and establish the stage. They also offer treatment options. The staging is determined by the type of cells and whether or the tumor has spread to other areas of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have worked in professions that involve asbestos, like plumbing or electrical work, manufacturing or construction, are at a higher risk of developing the disease. However, even if individuals aren't employed in these fields, they can still be exposed to asbestos through family members or through other sources. This is why anyone who believes they could be at risk should speak to a doctor. If they have an history of exposure to asbestos or mesothelioma, a specialist can assist them in finding out more about their risk.

Risk Factors

asbestos claim is the primary risk factor for mesothelioma. It accounts for as much as 80percent of cases. Exposure to asbestos can happen as a result of work, military service, or by living with a person who works with asbestos legal or used to do the same. When exposed to Asbestos Legal, particles can be breathed into the lungs and abdomen. They can cause irritation to the linings of the abdomen and trigger cancerous cells to form in the mesothelium. After exposure to asbestos, mesothelioma may be diagnosed between 15 and 60 years old.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more at chance of developing mesothelioma to people who are younger or more. It takes mesothelioma 20-60 years to show signs of cancer after the first exposure. It is also important to note that mesothelioma is a possibility in those who were exposed to asbestos but did not work with it directly. This is called indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more prone to. In addition, mesothelioma may be exacerbated by certain illnesses like pneumonia and asbestosis. It is also important to know that mesothelioma occurs more frequently for men than women. This is because men are more likely to be exposed to asbestos and endure a more exposure than women. Men are also more likely to live with someone who was exposed to asbestos and bring stray asbestos fibers home on their clothes. Women are less likely to come in contact with asbestos, and they are less likely to bring asbestos home on their clothing.

Diagnosis

It is difficult to recognize mesothelioma since its symptoms are often similar to other diseases. This can lead to victims being misdiagnosed.

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write note of the medical history of the patient which includes asbestos exposure. Doctors will also order an CT scan or chest X-ray in order 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 blood vessels and the heart and magnetic resonance imaging, also known as MRI, test, which makes use of magnets and radio waves to create precise images of the inside of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist then examines the tissue using a magnifying glass to determine if it is a cancerous cells.

Mesothelioma is classified based on the mesothelial type involved, whether those cells are malignant or benign, and the location of the tumor, its type, and the stage of the tumor. Certain types of mesothelioma may be more likely to develop metastasis or spread which is why it is crucial to get a definite diagnosis so that doctors can treat the disease before it gets out of control.

Doctors can also perform tests in the lab on tumors to identify specific genes, proteins or other factors that can aid in describing the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is crucial to remember that cancer can be treated, especially at its early stages. A lot of people suffering from mesothelioma endure the disease for a long time without spreading.

Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, which are small enough to not be felt or seen through the naked eye, can become airborne, causing irritation to the lining of the lung (pleura). As time passes, the irritation causes the formation of scar tissue, which causes changes in the cell structure that can eventually grow into tumors.

The pleura is the area that surrounds the lungs and the heart and the abdomen. Mesothelium consists of cells that react to asbestos which causes it to become inflamed and create scar tissue. These changes eventually result in malignant mesothelioma tumors.

The signs of pleural mesothelioma can include shortness of breath and chest pain, or the accumulation of fluid in the lung (pleural effusion). In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

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

There are many types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. Most doctors rely on an amalgamation of these techniques. Enrolling in clinical trials of mesothelioma treatments that are new could be beneficial for patients. Patients can learn more by consulting a mesothelioma expert who has treated the disease.
