Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of long, thin fibres. People who are regularly exposed to asbestos may develop lung diseases like mesothelioma.

It could take a long time before symptoms begin to manifest after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the outer lung lining, also known as pleura. It is the most common type of mesothelioma, making up between 70 and 79% of diagnosed cases. Patients suffering from this condition experience pain in the chest and shortness of breath and may experience the sensation of weight in the chest.

This type of cancer is typically caused by exposure to asbestos litigation, which is a grouping of minerals made up of microscopic fibres. These fibers, when inhaled cause irritation and DNA mutations. The pleura covers the lungs and chest cavity This means that these irritations can affect both the lungs and a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

Chest pain and shortness breath are the most frequent symptoms. Some patients also experience coughing, difficulty breathing or chest tightness. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. Construction, manufacturing, and shipbuilding are the most prevalent jobs that put people at high risk of developing pleural mesothelioma. People who have worked in the military may be at an especially high risk due to the frequent use of asbestos in Navy vessels and bunkers for the army.

The most commonly used staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient has when they are diagnosed will help their doctor determine the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or stage four will suffer a more negative prognosis than those in a lower stage. Mesothelioma in stage four can develop into the liver, heart or diaphragm. This makes the cancer more difficult to treat and increase the chances of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lung's lining it develops in a membrane that covers the abdominal cavity, which includes organs such as the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. The disease is less prevalent than pleural mesothelioma. There are only about 300-500 cases diagnosed each year.

Like pleural mesothelioma, symptoms may take years to appear. Patients typically have abdominal pain, and may also have a lump in their abdomen. This mesothelioma type can cause nausea, weight loss, and fever. Many of these symptoms could be misinterpreted as digestive issues, leading to a mistaken diagnosis.

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

These test results allow doctors to diagnose mesothelioma and determine the stage and suggest treatment options. The stage is determined by the type of cell as well as whether the cancer has spread.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos-containing jobs, such as electrical or plumbing work or in construction, manufacturing and manufacturing are more likely to contract the disease. Even if someone does not work in one of these areas, he or she can still be exposed through family members or other sources. Anyone who thinks they are at risk should consult a doctor. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in learning more about the risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, which accounts for as much as 80 percent of all cases. Exposure to Asbestos Case may occur through military service, work, or living with people who have worked with asbestos. Asbestos particles are inhaled by people who are exposed to it. These particles can cause irritation to the linings and cause cancerous cells to develop in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or more senior. This is because mesothelioma usually occurs between 20 and 60 years from the initial time of exposure before cancer symptoms appear. It is also important to know that mesothelioma is a possibility in people who were exposed to asbestos but didn't engage directly with it. This is known as indirect or secondary asbestos exposure, and is as hazardous as direct asbestos litigation exposure.

Smoking increases the chance of mesothelioma since it damages mesothelium. It also makes it more prone to. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. 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 it. Men are also more likely to have lived with someone who had been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less exposure to asbestos and don't typically carry asbestos settlement around on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to recognize because the symptoms often resemble other diseases. Because of this, victims are often misdiagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background including asbestos law exposure. Doctors can also order an X-ray of the chest or CT scan to check for lumps and other abnormalities and also to look for evidence of previous asbestos exposure like plaques in the pleura (thickened pleura with calcium deposits) and the formation of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart and magnetic resonance imaging, or MRI, test, which 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. In a surgical biopsy doctors remove a small piece of tissue from the peritoneum or pleura to conduct further tests. A pathologist is then able to examine the tissue with microscopes to determine if it has cancerous cells.

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

Doctors can also perform tests in the laboratory on tumors in order to determine specific proteins, genes or other factors that can aid in describing cancer characteristics and determine the best treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis is an incredibly frightening prospect. However, it is important to remember that the disease can be treated, particularly in its initial stages. A lot of people suffering from mesothelioma endure the disease for a long time without spreading.

Exposure to asbestos can cause mesothelioma through a variety of mechanisms. Asbestos fibres, too small to be felt or seen by naked eyes are able to become airborne and irritate the lining of the lung (pleura). As time passes the irritation can lead to the formation of scar tissue, which eventually lead to tumors.

The Pleura is a protective layer that covers the abdomen, heart, and lungs. Mesothelium is made up of cells that react when exposed to asbestos. They inflame 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 the accumulation of fluid on the lung (pleural effusion). In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal an area of concern in the lungs or stomach doctors will recommend biopsies. In the course of the procedure, doctors remove some of the fluid or tumor to allow for laboratory testing. The results can confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are a variety of treatment for mesothelioma, including surgery and chemotherapy. Most doctors utilize combinations of these treatments. Patients could also benefit from enrolling in a clinical trial of new mesothelioma treatment. Patients can learn more about the trials by consulting a mesothelioma specialist who has treated the disease.
