Mesothelioma and Asbestos

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

It may take decades for symptoms to show up after asbestos exposure. Different types of asbestos may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that occurs in the outer lung lining (pleura). It is the most common mesothelioma type, accounting for up between 70 and 79% of all diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling heavyness.

Exposure to asbestos, a group of minerals composed of microscopic fibers, usually causes this type of cancer. When inhaled, these fibers, cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity, so these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. Patients with this cancer have a past that includes asbestos exposure at work. Construction, manufacturing, and shipbuilding are the most frequent occupations that put people at a high danger of developing pleural melanoma. People who were in the military are at higher risk due to the frequent use of asbestos in Navy vessels and Army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used to treat the pleural cancer. The stage that the patient is in at the time of diagnosis can help determine the treatment plan they should receive. For instance, patients suffering from mesothelioma that is pleural in stage three or four have a poorer prognosis than patients with a lower stage. Mesothelioma in stage four is usually spread to the diaphragm, liver and/or a person's heart. This can make it more difficult to treat and increase the risk of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lung's lining, peritoneal cancer develops in a membrane that covers the abdominal cavity, including organs like the liver and intestines. As with pleural mesothelioma asbestos exposure is the primary cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed each year, which is less than the pleural asbestosis.

As with pleural asbestosis symptoms can take several years to manifest. Typically, patients experience abdominal pain and abdominal swelling. The symptoms of this type of mesothelioma could also include nausea, weight loss and fever. Many of these symptoms could be mistaken for gastrointestinal problems, leading to a misdiagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and performing a physical exam. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma and establish the stage. They can also suggest treatment options. Staging is determined based on the type of cells and whether or whether the cancer has spread to other parts of the body.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos compensation-containing jobs, such as plumbing or electrical work, or in construction, manufacturing and manufacturing, are more likely to develop the disease. Even if someone is not employed in any of these areas, he or she can be exposed to asbestos to asbestos through family members and other sources. Therefore, anyone who is concerned that they might be at risk should speak to an experienced doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can help them find out more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, accounting for up to 80 percent of cases. Exposure to asbestos can occur through work, military service, or living with those who worked with asbestos. When exposed to asbestos Case, particles can be breathed into the lungs and abdomen. These particles can cause irritation to the linings of the lungs, causing cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

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

Smoking increases the risk of developing mesothelioma due to the fact that it damages the mesothelium and makes it more prone to asbestos settlement. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. This is due to men being more likely to be exposed to asbestos and endure a more exposure than women. Additionally, men are more likely to live with someone who had asbestos exposure and bring asbestos fibers from their workplace on their clothes. Women tend to have less contact with asbestos and do not typically carry asbestos around on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other diseases. This can lead to victims being incorrectly diagnosed.

The first step in identifying 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 will also order a CT scan or chest X-ray to look for lumps, abnormalities, 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 and magnetic resonance imaging, also known as MRI, test that uses radio waves and magnets to create detailed images of the interior of the body. A surgical biopsy is another method for doctors to identify mesothelioma. When a biopsy is performed, doctors remove a tiny part of tissue from the pleura or the peritoneum to be further examined. A pathologist will then look at the tissue with a magnifying lens to determine if it is a cancerous cell.

The mesothelial type involved as well as the benign or malignant nature of those cells and the location and stage of the tumor, are used to classify the disease. Some types of mesothelioma are more likely to spread or metastasize, so it is important to get a definite diagnosis so that doctors can treat the disease before it becomes out of control.

Doctors may also conduct tests in the laboratory on a tumor to find specific genes, proteins and other factors that help them understand the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

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

Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibers, too small to see or feel by the naked eye can become airborne and irritate the lining of the lungs (pleura). In time the irritation causes the formation of scar tissues, which eventually lead to tumors.

The pleura is a protective covering that surrounds the lungs, heart and abdomen. Mesothelium consists of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. These changes can eventually cause mesothelioma cancers.

A shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all signs of the pleural msothelioma. In rare cases the cancer may be spread to the tissues around the heart and reproductive organs.

If scans of imaging reveal an area of concern in the stomach or lungs, a doctor will order biopsies. During the procedure doctors remove small amounts of liquid or tumor for lab tests. The results will confirm a mesothelioma diagnosis, and determine the best treatment option.

There are a variety of treatment for mesothelioma such as chemotherapy and surgery. Most doctors rely on the combination of these methods. Participating in clinical trials of new mesothelioma treatment may also be beneficial for patients. Patients can learn more about the trials by consulting a mesothelioma expert who has treated the disease.
