Mesothelioma and Asbestos

Asbestos is a natural mineral that comes in long, thin fibres. People who are exposed to asbestos are at risk of developing 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 lung's outer lining, also known as the pleura. It is the most frequent mesothelioma type, accounting for up 70% to 79% of all diagnosed cases. Patients with this disease experience pain in the chest and shortness of breath and may also feel a sensation of heaviness in the chest.

This type of cancer is typically caused by exposure to asbestos legal which is a collection of minerals that are made up of microscopic fibres. When inhaled, these fibers cling to the lungs and cause irritation that leads to scarring and DNA mutations. The pleura surrounds the chest cavity and lungs and therefore, these irritations could affect both the lungs as well as a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Some patients may also suffer from chest tightness and coughing, or breathing difficulties. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. The most prevalent jobs that put people at risk of developing pleural mesothelioma are manufacturing, construction and shipbuilding. People who have served in the military could be at an especially high risk due to the widespread asbestos usage in Navy ships and army bunkers.

The most commonly used staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at the time of diagnosis will help determine the treatment plan they will receive. For example, patients with mesothelioma that is pleural in stage three or four have a poorer prognosis than those with lower stages. Stage four mesothelioma may develop into the liver, heart or diaphragm. This could make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, which is found in the lining of the lung it develops in a membrane that surrounds the abdominal cavity, which includes organs such as the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. The disease is less common than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, the symptoms can take years to show. Most patients experience abdominal pain and an abdominal mass. This type of mesothelioma may also cause nausea, weight loss, and fever. Many of these symptoms are similar to those experienced by digestive problems, which can lead to incorrect diagnosis.

Typically, doctors can identify mesothelioma by conducting an exhaustive health history and physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can detect tumors as well as other signs of cancer which aren't visible on X-rays.

These test results allow doctors to diagnose mesothelioma, determine the stage and recommend treatment options. The staging is determined by the type of cell and whether or the cancer has spread to other regions of the body.

The most important risk factor for mesothelioma is exposure to asbestos lawsuit. People who have worked in jobs that involve asbestos, like plumbing, electrical work, manufacturing or construction, are at greater risk of developing the disease. Even if a person isn't employed in one of these fields, he or she can be exposed to asbestos to asbestos through family members and other sources. For this reason, anyone who suspects they may be at risk should speak to a doctor. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about their risk.

Risk Factors

Asbestos is the main mesothelioma-related risk factor. It is responsible for up to the 80% of cases. Exposure to asbestos can happen as a result of work, military service, or living with those who worked with asbestos. When exposed to asbestos, small particles can be breathed into the lungs and abdomen. They can cause irritation to the linings of the abdomen and cause cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos case; relevant internet site,.

Other risk factors include smoking, genetics and aging. The people in their 40s or 50s are at a higher risk of developing mesothelioma as compared to people who are younger or more. It is because mesothelioma generally lasts between 20 and 60 years after the initial time of exposure before the first signs of cancer appear. It is important to note, too, that mesothelioma may occur in those who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases the risk of developing mesothelioma due to the fact that it damages the mesothelium and makes it more susceptible to asbestos. Mesothelioma can also be caused by certain diseases, such as asbestosis and pneumonia. It is also important to note that mesothelioma occurs more frequently in men than women. This is because men are more likely to be exposed to asbestos and endure a an extended period of exposure than women. Men are also more likely to have lived with someone who has worked with asbestos, and to carry asbestos fibers on their clothing. Women are less likely to come in contact with asbestos, and they are less likely to bring asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to diagnose because the symptoms often resemble other diseases. Due to this, patients are sometimes misdiagnosed.

The first step to diagnose 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 asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance imaging, or MRI test, which makes use of magnets and radio waves in order to create a series detailed images of inside the body. A surgical biopsy is a different way for doctors to diagnose mesothelioma. A surgical biopsy is when doctors remove a small amount of tissue from the peritoneum or pleura for further analysis. A pathologist will then look at the tissue using a magnifying glass to determine if it is a cancerous cells.

Mesothelioma is classified according to the type of mesothelial cells involved, whether those cells are benign or malignant, and the location, type, and stage of the cancer. Certain mesothelioma types have greater risk of spreading or metastasizing, so it's important to determine the type of mesothelioma to ensure that the doctors can treat it before it becomes out of control.

Doctors may also conduct laboratory tests on tumors to determine specific genes, proteins and other factors which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be frightening. However, it is important to keep in mind that the cancer is treatable, particularly in its earlier stages. Many patients with mesothelioma survive for years with the disease, without spreading to other organs of their body.

Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibres, tiny enough to be felt or seen by naked eyes are able to become airborne, irritating the lung's lining (pleura). In time, the irritation leads to the formation of scar tissue, which eventually lead to tumors.

The pleura covers the lungs and the heart, as well as the abdomen. Mesothelium is composed of cells that react to asbestos litigation and cause it to enflame and form scar tissue. In time, these changes can lead to the development of malignant mesothelioma tumors.

The signs of pleural mesothelioma can include breathing problems and chest pain, or the accumulation of fluid in the lung (pleural effusion). In rare cases cancer may spread to the tissues around the reproductive organs and heart.

If imaging scans show an area of concern in the lungs or stomach the doctor will request a biopsies. During the procedure doctors remove some of the fluid or tumor for lab tests. The results can confirm a mesothelioma diagnosis, and provide the best treatment plan.

There are a variety of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. Most doctors rely on a combination of these methods. Enrolling in clinical trials of mesothelioma treatments that are new could be beneficial to patients. To find out more, patients should speak to mesothelioma specialists who have experience treating the condition.
