Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is made up of long, thin fibres. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma or other lung diseases.

Symptoms of these diseases may not manifest for years after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining, or pleura. It is the most frequent type of mesothelioma, making up 70% to 79% of diagnosed cases. This condition causes chest pain, breath shortness, and a feeling of weightiness.

Exposure to asbestos, a group of minerals composed of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled cause irritation and DNA mutations. The pleura surrounds 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 years after exposure.

The most common symptoms of pleural melanoma are chest discomfort and shortness of breath. Patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this cancer have a past that includes asbestos exposure at work. The most frequent jobs that expose people to the risk of developing pleural mesothelioma are manufacturing, construction and shipbuilding. Individuals who have served in the military are at greater risk due the widespread use of asbestos in Navy vessels and Army bunkers.

The most popular staging method for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage that a patient is at when they are diagnosed will aid their doctor in determining the most effective treatment plan for them. For instance, patients who have mesothelioma that is pleural in stage three or four have a poorer prognosis than those in lower stages. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This makes it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lung's lining the peritoneal cancer is a result of a membrane that surrounds the abdominal cavity, including organs like the intestines and the liver. Similar to pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. There are only 300-500 cases diagnosed annually, which is less than the pleural asbestosis.

Like pleural mesothelioma, symptoms can take years to show. Most patients are afflicted with abdominal pain as well as a mass in the abdomen. This kind of mesothelioma can also cause nausea, weight loss, and fever. A lot of these symptoms can be mistaken for gastrointestinal problems which can lead to a false diagnosis.

Generally, doctors can find mesothelioma after an exhaustive health history and physical exam. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. Vimeo can reveal cancerous tumors or other symptoms of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage. They can also recommend treatment options. The stage of the disease is determined based on the cell type and whether or the cancer has spread to other parts of the body.

Asbestos exposure is the biggest risk factor. People who have worked in jobs which require asbestos, such as plumbing manufacturing, electrical work or construction, are at increased risk of developing the disease. However, even if individuals aren't employed in these fields they could 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 expert. If they have any history of exposure to asbestos or mesothelioma, a specialist can assist them in learning more about the risk.

Risk Factors

Asbestos is the most significant risk factor in mesothelioma. It accounts for up to 80percent of cases. Exposure to asbestos can happen through work, military service or through living with a person who works with asbestos or was previously exposed to doing such. Asbestos particles can be inhaled by those who are exposed to asbestos. These irritate the linings and cause cancerous cells to grow 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 age. People in their 40s and 50s are at greater risk of developing mesothelioma compared to people who are younger or more. It is because mesothelioma generally lasts between 20 and 60 years from the initial exposure before cancer symptoms appear. It is important to keep in mind, too, that mesothelioma may be present in those who have been exposed to asbestos, but without having worked with it directly. This is known as indirect or secondary exposure to asbestos. It is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more susceptible. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more common for men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and work with it. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos fibers on their clothing. Women are less likely to come into exposure to asbestos and do not typically carry asbestos around on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being frequently similar to other illnesses. Due to this, patients are sometimes wrongly diagnosed.

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

Other diagnostic tests include a magnetic resonance imaging, or MRI test, that uses radio waves and magnets in order to create a series of detailed images of the inside of the body. Another way for doctors to detect mesothelioma is through an operation called a biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist can then examine the tissue under microscopes to determine whether it has cancerous cells.

Mesothelioma is classified according to the mesothelial type involved, whether the cells are malignant or benign 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 establish a definitive diagnosis to ensure that doctors are able to treat the disease before it becomes out of control.

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

Treatment

A mesothelioma diagnose can be frightening. It is important to remember, however, that cancer can be treated, particularly in its initial stages. A lot of people suffering from mesothelioma endure the disease for many years without it spreading.

Exposure to asbestos can cause mesothelioma by many mechanisms. Asbestos fibers, which are too small to detect or feel with the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time irritation leads to formation of scar tissue which leads to changes in the structure of cells that eventually develop into tumors.

The pleura is the area that surrounds the heart and lungs and the abdomen. Mesothelium is made up of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. These changes can lead to malignant mesothelioma tumours.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all indications of the pleural Msothelioma. In rare cases cancer may spread to the tissues surrounding the reproductive organs and heart.





A doctor will order a biopsy if imaging scans show a potential mass in the lungs or stomach. During the procedure doctors remove a small amount of fluid or tumor to allow for laboratory testing. The results can confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are several types of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. Most doctors utilize a combination of these treatments. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial for patients. Patients can learn more about the trials by consulting a mesothelioma expert who has treated the condition.
