Mesothelioma and Asbestos

Asbestos, a mineral that naturally occurs in the form of long, thin fibers. Workers who are exposed asbestos on a regular basis are at risk of developing mesothelioma as well as other lung diseases of different types.

The symptoms of these diseases might not be evident for a long time after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the outer lung lining, or pleura. It is the most common mesothelioma type, accounting for up between 70 and 79% of all diagnosed cases. People with this condition feel chest pain and breath shortness and may experience the sensation of weight in the chest.

Exposure to asbestos, a class of minerals made of microscopic fibers causes this type of cancer. The fibers, when inhaled can cause irritation and DNA mutations. The pleura covers the lungs and chest cavity This means that these irritations can affect both the lungs as well as a person's heart. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma are chest pain and shortness of breath. Some patients also experience coughing, difficulty breathing, or chest tightness. People with this cancer often have previous exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. Individuals who have been in the military may be at a higher risk due to the frequent asbestos use in Navy ships and bunkers used by 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 that the patient is in at the time of diagnosis can help determine the treatment plan they should follow. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable prognosis compared to those who are in a less advanced stage. Stage four mesothelioma can spread to the heart, liver or diaphragm. This can make the cancer more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum, it is a membrane that lines the abdominal cavity and organs like the intestines and the liver. Similar to pleural mesothelioma mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to manifest. Patients usually suffer from abdominal pain and could also experience a mass in their abdomen. The symptoms of this kind of mesothelioma may also include nausea, weight loss and fever. Many of these symptoms are similar to symptoms of digestive problems, which can lead to confusion in diagnosis.

Doctors can detect mesothelioma by looking over the medical history of the patient and conducting a physical exam. Imaging tests such as X-rays or CT scans are a way to detect mesothelioma. These tests can identify tumors and other cancer signs which aren't evident on X-rays.

These test results enable doctors to diagnose mesothelioma and determine the stage. They can also recommend treatments. Staging is determined based on the cell type and whether or not the tumor has spread to other regions of the body.

The most significant mesothelioma risk factor is exposure to asbestos claim. People who have been exposed to asbestos in occupations, like electrical or plumbing work or in construction and manufacturing are more likely to develop the disease. Even if someone isn't employed in one of these areas however, they may still be exposed through family members or other sources. Anyone who suspects that they're at risk should speak with an expert. A mesothelioma specialist can assist those who have a history with asbestos to learn more about their risk.

Risk Factors

asbestos case (look at here) exposure is the main mesothelioma risk factor, which accounts for as much as 80 percent of all cases. Exposure to asbestos can occur through military service, work, or living with someone who used to work with asbestos law. Asbestos particles can be inhaled by those who are exposed to it. These particles can cause irritation to the linings, causing cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and age. People in their 40s or 50s are at greater risk of developing mesothelioma compared to people who are younger or more. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to note that mesothelioma could occur in people who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium, which makes it more vulnerable to asbestos. In addition, mesothelioma may be worsened by certain diseases like pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for a longer time and to have worked with asbestos law for longer periods of time. Also, men are more likely to live with someone who has was exposed to asbestos and bring asbestos fibers that have escaped home on their clothes. Women are less likely to come exposed to asbestos, and they don't usually bring asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to diagnose because the symptoms are often similar to other diseases. This can result in patients being misdiagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history including asbestos exposure. Doctors may also request a CT scan or chest X-ray to look for abnormalities, lumps 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 a magnetic resonance imaging, or MRI test that uses radio waves and magnets to create detailed images of the inside of the body. Another method doctors use to diagnose mesothelioma is through an operation called a biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the pleura or peritoneum to conduct further tests. A pathologist is then able to examine the tissue under a microscope to see if it is contaminated with cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether those cells are benign or malignant and also the location, type, and stage of the tumor. Certain types of mesothelioma are more likely to spread or metastasize, so it is important to establish a definitive diagnosis so doctors can treat the disease before it gets out of control.

Doctors may also conduct tests in the laboratory on tumors to identify specific genes, proteins or other elements that can aid in describing cancer characteristics and plan treatment. These results are called staging.

Treatment

A mesothelioma diagnose can be frightening. But, it is crucial to keep in mind that the cancer is treatable, especially in its early stages. Many people with mesothelioma live for a long time without the disease spreading to other parts of their body.

Asbestos exposure can cause mesothelioma through various mechanisms. Asbestos fibers, which are too small to be able to see or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). As time passes irritation can lead to formation of scar tissue which causes changes in the structure of cells that can eventually grow into tumors.

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

Symptoms of pleural mesothelioma include breathing problems and chest pain, or a buildup of fluid on the lung (pleural effusion). In rare cases, cancer can spread into the tissues around the reproductive organs as well as the heart.

If imaging scans reveal an area of concern in the stomach or lungs the doctor will request biopsies. During the procedure, doctors remove a small sample of the fluid or tumor for laboratory analysis. The results will confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

There are many types of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors utilize a combination of these methods. Patients can also benefit by participating in a clinical study of new mesothelioma treatments. To find out more, patients should speak to a mesothelioma specialist who has expertise in treating the condition.
