Mesothelioma and Asbestos

Asbestos is a mineral that naturally occurs in the form of long, thin fibers. Workers who are exposed to asbestos legal regularly risk developing mesothelioma and other lung diseases of different types.

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

Pleural Mesothelioma

Pleural mesothelioma occurs in the outer lung lining, also known as the pleura. It is the most prevalent mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. Patients suffering from this condition feel chest pain and breathlessness and may also feel a sensation of heaviness in the chest.

Exposure to asbestos, a class of minerals composed of microscopic fibers, typically causes this kind of cancer. Once inhaled, the fibers cling to the lung and cause irritation that leads to scarring and DNA mutations. Pleura covers both the chest cavity as well as the lungs, so irritations can also affect the heart. Mesothelioma typically doesn't manifest until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural mesothelioma are chest discomfort and shortness of breath. Some patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. Patients with this cancer have a past that includes asbestos exposure at work. Manufacturing, construction and shipbuilding are among the most common occupations that put people at high chance of developing pleural mesothelioma. People who have worked in the military could be at risk due to the widespread use of asbestos in Navy ships and army bunkers.

The most common staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient is in at diagnosis will help their doctor determine the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will suffer a more negative prognosis than those in a less advanced stage. Stage four mesothelioma can develop into the liver, heart or diaphragm. This makes it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, that develops in the lung's lining it develops in a membrane that covers the abdominal cavity, including organs like the intestines and the liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed annually, which is less than pleural asbestosis.

As with pleural mesothelioma symptoms may take years to appear. Typically, patients experience abdominal pain and abdominal swelling. This type of mesothelioma may cause nausea, weight loss and fever. Many of these symptoms are similar to those experienced by gastrointestinal issues, which can lead to confusion in diagnosis.

The doctors can detect mesothelioma through reviewing the medical history of the patient and conducting a physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to detect mesothelioma. These tests can identify tumors and other signs of cancer that aren't evident on X-rays.

These test results allow doctors to diagnose mesothelioma, determine the stage of the disease and suggest treatment options. The stage of the disease is determined based on the type of cell and whether or not the cancer has spread to other parts of the body.

Asbestos exposure is the most important risk factor. People who have worked in asbestos-related professions, such as electrical or plumbing work or in construction and manufacturing, are more likely to contract the disease. However, even if people do not work in these fields they may be exposed to asbestos through family members or other sources. For this reason, anyone who is concerned that they might be at risk should speak to an experienced doctor. If they have any history of exposure to asbestos settlement, a mesothelioma specialist can help them find out more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma which accounts for as much as 80 percent of cases. Exposure to asbestos may occur due to work, military service, or by living with someone who works with asbestos or used to do the same. Asbestos particles are inhaled by those who are exposed to it. These irritate the linings and cause cancerous cells to grow in the mesothelium. Mesothelioma can take anywhere 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 at a higher risk of developing mesothelioma compared to those younger or older. It takes mesothelioma between 20 and 60 years to manifest cancer symptoms after the first exposure. It is important to remember, too, that mesothelioma may develop in those who have been exposed to asbestos without having directly worked with it. This is known as indirect or secondary exposure to asbestos, and it can be just as dangerous as direct exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It also makes it more prone to. Mesothelioma is also aggravated by certain illnesses such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is due to the fact that men are more likely to work with asbestos case (oncob2B.co.kr) and have an extended period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and do not typically carry asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to identify because the symptoms often resemble other diseases. This can lead to victims being wrongly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history, including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray to check 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 an echocardiogram which examines the blood vessels and the heart and magnetic resonance imaging, also known as MRI test, which makes use of magnets and radio waves to make a series of detailed images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. In a surgical biopsy doctors remove a small piece of tissue from the peritoneum or pleura to conduct further tests. A pathologist can then examine the tissue using a magnifying glass to determine if it contains cancerous cell.

Mesothelioma is classified according to the mesothelial type involved, whether the cells are benign or malignant, and the location of the tumor, the type, and the stage of the tumor. Some types of mesothelioma are more likely to grow or spread which is why it is crucial to have a clear diagnosis so that doctors can treat the disease before it becomes out of control.

Doctors may also conduct laboratory tests on tumors to identify specific proteins, genes, or other factors which can aid in describing the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be frightening. It is crucial to remember that cancer can be treated particularly in its initial stages. Many people with mesothelioma live for a long time with the disease, without spreading to other organs of their body.

Exposure to asbestos law can cause mesothelioma by various mechanisms. Asbestos fibers that are small enough to not be felt or seen through the naked eye can be airborne, causing irritation to the lining of the lung (pleura). In time, the irritation causes the formation of scar tissue, which leads to changes in the cell structure which eventually lead to tumors.

The pleura surrounds the lungs and heart and also the abdomen. Mesothelium is made up of cells that react to exposure to asbestos which causes it to become inflamed and develop scar tissue. Overtime, these changes cause the development of malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness and chest pain as well as a buildup of fluid in the lungs (pleural effusion). In rare cases, cancer can spread into the tissues surrounding the reproductive organs as well as the heart.

A doctor will request a biopsy if imaging scans show a potential mass in the lungs or stomach. In the course of the procedure, doctors remove small amounts of liquid or tumor for laboratory testing. The results can confirm the diagnosis of mesothelioma and indicate the best treatment option.

There are several types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. Most doctors use combinations of these treatments. Participating in clinical trials for mesothelioma treatments may be beneficial to patients. To find out more, patients should speak with mesothelioma specialists who have expertise in treating the condition.
