Mesothelioma and Asbestos

Asbestos is a mineral that naturally forms in the form of long, thin fibers. People who are regularly exposed to asbestos may develop lung diseases like mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, or pleura. It is the most prevalent type of mesothelioma, making up between 70 and 79% of all diagnosed cases. The condition can cause chest discomfort, shortness of breath and a feeling of weightiness.

Exposure to asbestos, a family of minerals composed of microscopic fibers, usually causes this type of cancer. The fibers, when inhaled, cause irritation and DNA mutations. The pleura is the area that surrounds the chest cavity and lungs, so these irritations can affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most common symptoms. Patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. The most common jobs that expose people to the risk of developing pleural cancer are construction, manufacturing and shipbuilding. People who were in the military are at a greater risk due to the widespread use of asbestos in Navy vessels and bunkers for the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most common staging system used to treat the pleural cancer. The stage a patient is in at the time of diagnosis can help determine the treatment plan they should receive. Patients suffering from pleural mesothelioma who is in stage three or stage four will suffer a more negative prognosis than those who are in a less advanced stage. Mesothelioma in stage four can spread to the liver, heart, or diaphragm. This can make it more difficult to treat and increases the risk of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lung's lining, peritoneal cancer develops in a membrane that covers the abdominal cavity, including organs such as the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. There are only 300-500 cases diagnosed each year this is less than pleural asbestosis.

Like pleural mesothelioma, symptoms can take years to show. Patients usually experience abdominal pain, and may also have a lump in their abdomen. The symptoms of this kind of mesothelioma could also include nausea, weight loss and fever. Many of these symptoms can be mistaken for gastrointestinal problems and can lead to a misdiagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and performing a physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors and other symptoms of cancer that aren't visible on an X-ray.

These tests enable doctors to diagnose mesothelioma, identify the stage and recommend treatment options. Staging is determined based on the type of cell and whether or whether the cancer has spread to other parts of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have worked in jobs that require asbestos, like plumbing or manufacturing, electrical work or construction, are at a higher risk of developing the disease. Even if a person is not employed in one of these fields, he or she can be exposed to asbestos through family members and other sources. This is why anyone who suspects they may be at risk should talk to an experienced doctor. If they have any history of exposure to asbestos, a mesothelioma specialist can help them find out more about their risk.

Risk Factors

Asbestos exposure is the main mesothelioma risk factor, accounting for up to 80 percent of cases. Exposure to asbestos legal can occur due to work, military service or by living with a person who is exposed to asbestos compensation or has previously done such. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings and can cause cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos law.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. It takes mesothelioma 20-60 years to manifest cancer symptoms after the first exposure. It is important to keep in mind that mesothelioma can be present in people who have been exposed to asbestos without having worked with it directly. This is known as indirect or secondary asbestos legal exposure, and is as dangerous as direct asbestos exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more susceptible. In addition, mesothelioma may be exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in males than females. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with it. Men are also more likely to have lived with someone who has worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to be less exposed to asbestos, and don't typically carry asbestos claim on their clothes.

Diagnosis

It is difficult to identify mesothelioma because its symptoms are often similar to other conditions. This could lead to patients being wrongly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical history, including asbestos exposure. Doctors may also request an CT scan or chest X-ray in order to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques in the pleura, thickened pleura and calcium deposits.

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, which uses radio waves and magnets to create detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is by performing an operation called a biopsy. During a surgery biopsy doctors take a tiny piece of tissue from pleura or the peritoneum to be tested further. A pathologist can examine the tissue under a microscope to see if it contains cancerous cells.

The type of mesothelial cell involved as well as the benign or malignant nature of those cells, as well as the location and stage of the tumor, are used to classify the disease. Certain types of mesothelioma may be more likely to spread or metastasize and spread, therefore it is essential to have a clear diagnosis so doctors can treat the disease before it goes out of control.

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

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to keep in mind that cancer can be treated particularly in its early stages. Many people with mesothelioma can endure the disease for many years without it spreading.

Exposure to asbestos can trigger mesothelioma in a number of ways. Asbestos fibers, which are tiny enough to be felt or observed through the naked eye are able to become airborne, irritating the lung's lining (pleura). As time passes, the irritation causes the formation of scar tissue which can cause changes in the structure of cells which eventually lead to tumors.

The pleura is a protective covering that protects the lungs, heart and abdomen. Mesothelium is composed of cells that react when exposed to asbestos. They inflame the tissue and cause it to scar. As time passes, these changes cause the development of malignant mesothelioma cancers.

Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all signs of the pleural Msothelioma. In rare instances cancer can spread to the tissues that surround the reproductive organs and the heart.

A doctor will request biopsy if scans reveal a possible lung tumor or stomach. In the course of the procedure, doctors remove a small amount of fluid or tumor for lab tests. The results will confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are many types of treatment for mesothelioma, such as chemotherapy and surgery. The majority of doctors use the combination of these methods. Participating in clinical trials of mesothelioma treatments that are new could be beneficial for patients. To learn more, patients should consult mesothelioma experts who have had experience treating the disease.
