Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in thin, long fibres. People who are exposed to asbestos regularly are at risk of developing mesothelioma or other types of lung diseases.

It can take years for symptoms to appear after asbestos exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining or the pleura. It is the most prevalent mesothelioma type and is responsible for 70 to 79% of all diagnosed cases. This condition causes chest discomfort, shortness of breath and a feeling weightiness.

Exposure to asbestos compensation, a group of minerals comprised of microscopic fibers, usually causes this type of cancer. When inhaled, these fibers stick inside the lung and cause irritation which leads to scarring and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, which means that irritations can also affect the heart. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also feel tightness in their chest and coughing, or breathing difficulties. Patients with this cancer have a past that includes asbestos exposure at work. The most common jobs that expose workers to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. Individuals who have served in the military are at a greater risk due the frequent 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 adenocarcinoma. The stage that a patient is at when they are diagnosed will aid their doctor in determining the best treatment plan for them. For instance, patients who have mesothelioma pleural stage three or four have a worse prognosis than patients with a lower stage. Stage four mesothelioma often spreads to the diaphragm, liver and/or a person's heart. This makes the cancer more difficult to treat and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum -- a membrane that lines the abdominal cavity and organs such as the intestines and liver. Similar to pleural mesothelioma, asbestos, click now, exposure is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed annually which is lower than the pleural asbestosis.

As with pleural asbestosis, symptoms can take years to show. Patients generally have abdominal pain, and may also have a lump in their abdomen. This type of mesothelioma may cause nausea, weight loss, and fever. Many of these symptoms are similar to symptoms of gastrointestinal issues, which can result in incorrect diagnosis.

Generally speaking, doctors can detect mesothelioma after an extensive medical history and physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can show cancerous tumors or other symptoms of cancer that aren't apparent on an X-ray.

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

The most important mesothelioma risk factor is exposure to asbestos. People who have worked in asbestos-containing occupations, like electrical or plumbing work, or in construction, manufacturing and manufacturing, are more likely to contract the disease. Even if they do not work in these areas they could be exposed to asbestos through relatives or other sources. Therefore, anyone who is concerned that they might be at risk should talk to an expert. 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 a major risk factor for mesothelioma making up as much as 80 percent of cases. Exposure to asbestos can occur through military service, work or living with people who have worked with asbestos. Asbestos particles can be inhaled by those who are exposed to asbestos. These irritate the linings and can cause cancerous cells to develop in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more at risk of developing mesothelioma compared to those younger or older. This is because mesothelioma usually takes 20 to 60 years after the initial exposure before the first signs of cancer appear. It is also important to note that mesothelioma is a possibility in those who were exposed to asbestos but did not deal with it directly. This is called secondary or indirect exposure to asbestos settlement, and it can be just as dangerous as direct exposure.

Smoking increases the risk of developing mesothelioma since it damages the mesothelium, which makes it more susceptible to asbestos. Furthermore, mesothelioma is worsened by certain diseases like pneumonia and asbestosis. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for a longer period of time and to work with asbestos for longer durations and to work with it. Men are also more likely to live with someone who had asbestos exposure and bring stray asbestos fibers home on their clothing. Women are less likely to come into contact with asbestos and rarely carry asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to diagnose because the symptoms often resemble other conditions. This can lead to victims being incorrectly diagnosed.

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

Other diagnostic tests include a magnetic resonance scan, or MRI test, which makes use of magnets and radio waves in order to produce a series of precise images of the insides of the body. Another way doctors can diagnose mesothelioma is through an operation called a biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist then examines the tissue using an magnifying glass to determine whether it contains cancerous cell.

The type of mesothelial cells involved and the benign or malignant nature of those cells and the location, type and stage of the tumour, are used to classify the disease. Certain types of mesothelioma are at an increased risk of metastasizing or spreading therefore it is essential to establish a clear diagnosis to ensure that the doctors can treat it before it becomes out of control.

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

Treatment

A diagnosis of mesothelioma may be frightening. However, it's important to keep in mind that the cancer is treatable, particularly in its earlier stages. Many patients with mesothelioma endure the disease for a long time, without spreading.

Exposure to asbestos can cause mesothelioma in a number of ways. Asbestos fibers, which are too small to be able to see or feel with the naked eye, can become airborne and cause irritation to the lining of the lungs (pleura). In time the irritation causes the formation of scar tissue, which eventually lead to tumors.

The Pleura is a protective layer that protects the lungs, heart and abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. In time, these changes can result in the growth of malignant mesothelioma cancers.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all signs of the pleural mesothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.

A doctor will order biopsy if imaging scans show a potential mass in the lungs or stomach. During the procedure doctors remove small amounts of fluid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and determine the best treatment plan.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors use combinations of these treatments. Patients could also benefit from enrolling in a clinical trial of new mesothelioma treatments. To learn more about the trials, patients should speak with a mesothelioma specialist who has had experience treating the disease.
