Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in long, thin fibres. Workers who are exposed asbestos on a regular basis are at risk of developing mesothelioma as well as other types of lung diseases.

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 lung's outer lining, also known as pleura. It is the most common type of mesothelioma, making up 70% to 79% of diagnosed cases. People with this condition suffer from chest pain and breathlessness and may also feel the sensation of weight in the chest.

This kind of cancer is often caused by exposure to asbestos, which is a collection of minerals made up of microscopic fibres. When inhaled, these fibers, cause irritation and DNA mutations. The pleura covers the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as a person's heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Chest pain and shortness breath are the most frequently reported symptoms. Patients may also feel tightness in their chest, coughing or difficulty breathing. Patients with this type of 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. People who have served in the military are at an especially high risk due to the widespread asbestos use in Navy vessels and bunkers used by the army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage the patient is in at the moment of diagnosis will determine what treatment plan they should receive. For instance, patients who have a pleural mesothelioma in stage three or four have a worse prognosis than patients with lower stages. Stage four mesothelioma often spreads to the diaphragm, the liver and/or a person's heart. 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 lung's lining it develops in a membrane that surrounds the abdominal cavity, including organs such as the intestines and liver. As with pleural mesothelioma exposure to asbestos is the reason for peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed annually, which is less than the pleural asbestosis.

Like pleural mesothelioma, the symptoms can take a long time to manifest. Patients generally have abdominal pain, and may also have a lump in their abdomen. The symptoms of this kind of mesothelioma can also include nausea or weight loss, as well as fever. Many of these symptoms can be misinterpreted as digestive issues and can lead to a mistaken diagnosis.

Doctors can identify mesothelioma by examining the patient's medical history and performing a physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can show tumors, as well as other signs of cancer that aren't apparent on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also recommend treatments. The staging is determined by the type of cell and whether or whether the tumor has spread to other parts of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have been in occupations that require asbestos, such as plumbing, manufacturing, electrical work or construction, are at a higher risk of developing the disease. Even if an individual is not employed in any of these areas, he or she can still be exposed through family members or other sources. Anyone who suspects that they may be at risk should consult an expert. If they have a history of asbestos exposure and mesothelioma is a concern, a specialist will assist them in learning more about the risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It accounts for as much as 80% of all cases. Exposure to asbestos can occur as a result of work, military service or by living with a person who is exposed to asbestos or has previously done so. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. These particles can cause irritation to the linings and trigger cancerous cells to develop in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos legal.

Other risk factors include smoking, genetics, and the advancing age. The people in their 40s or 50s are more at chance of developing mesothelioma to people who are younger or more. This is because mesothelioma usually lasts between 20 and 60 years from the first exposure to asbestos before cancer symptoms appear. It is important to note that mesothelioma may develop in those who have been exposed to asbestos without having been directly exposed to it. This is called indirect or secondary exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the risk of mesothelioma, since it damages mesothelium. It can also make it more vulnerable. Mesothelioma is also aggravated by certain illnesses, including 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 case for longer periods of time and to have worked with asbestos for longer durations and to work with it. Additionally, men are more likely to live with someone who has was exposed to asbestos and bring asbestos law fibers that have escaped home on their clothing. Women tend to have less exposure to asbestos and rarely carry asbestos around on their clothes.

Diagnosis

It is difficult to identify mesothelioma because its symptoms are frequently similar to other illnesses. This is why patients are sometimes misdiagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical background including asbestos exposure. Doctors may also request a CT scan or chest X-ray to look for lumps, abnormalities and evidence of exposure to asbestos. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance imaging or MRI test, that uses magnets and radio waves in order to produce a series of precise images of the inside of the body. Another way for doctors to detect mesothelioma is by performing the procedure of a surgical biopsy. During a surgery biopsy, doctors remove a tiny part of tissue from the pleura or the peritoneum to be examined further. A pathologist can then examine the tissue with an magnifying glass to determine whether it contains cancerous cell.

The type of mesothelial cell involved as well as the benign or malignant nature of those cells as well as the location and stage of the tumor, are used to classify the disease. Certain types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to get a definite diagnosis to ensure that doctors are able to treat the disease before it goes out of control.

Doctors may also conduct laboratory tests on a tumor to identify particular proteins, genes and other factors that can help them describe the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be frightening. It is important to keep in mind, however, that cancer can be treated particularly in its early stages. A lot of people suffering from mesothelioma be afflicted for a long time without spreading.

Exposure to asbestos may cause mesothelioma in a number of ways. Asbestos fibers that are small enough to not be felt or observed through the naked eye are able to become airborne, causing irritation to the lung's lining (pleura). As time passes irritation can lead to formation of scar tissue, which can cause changes in the structure of cells which eventually lead to tumors.

The pleura surrounds the lungs and the heart and also the abdomen. Mesothelium is made up of cells that react to asbestos, causing it to inflame and form scar tissue. These changes eventually cause mesothelioma cancers.

The symptoms of pleural mesothelioma are breathing problems and chest pain, or the accumulation of fluid on the lungs (pleural effusion). In rare cases, the cancer can spread to the tissues surrounding the heart and reproductive organs.

A doctor will request a biopsy if imaging scans reveal a possible tumor in the lungs or stomach. During the procedure, doctors will remove a small sample of the fluid or tumor for lab analysis. The results can confirm a mesothelioma diagnosis, and indicate the best treatment option.

There are several types of mesothelioma treatment options, including surgery, chemotherapy 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 consult a mesothelioma specialist who has had experience treating the disease.
