Mesothelioma and Asbestos

Asbestos, a mineral that occurs naturally in the form of thin, long fibers. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma as well as other types of lung diseases.

It may take decades for symptoms to show up after asbestos exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

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

This kind of cancer is typically caused by exposure to asbestos which is a collection of minerals that are made up of microscopic fibres. Once inhaled, these fibers are absorbed into the lung and cause irritation that causes scarring and DNA mutations. Pleura covers both the chest cavity and the lungs, so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest discomfort and shortness of breath. Some patients may also feel tightness in their chest and coughing, or breathing difficulties. Patients with this type of cancer have a past that includes asbestos exposure at work. Manufacturing, construction and shipbuilding are the most frequent jobs that put people at a high danger of developing pleural melanoma. People who served in the military are at a greater risk due the frequent use of asbestos in Navy vessels and bunkers in the Army.

The most popular staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage the patient is in at the time of diagnosis will help determine the treatment plan they should follow. Patients who have pleural mesothelioma which is in stage three or stage four will have a less favorable prognosis compared to those in a lower stage. Stage four mesothelioma often spreads to the diaphragm, the liver and/or a person's heart. This can make the cancer more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lung's lining, peritoneal cancer develops in a membrane that covers the abdominal cavity, which includes organs like the liver and intestines. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed each year which is lower than pleural asbestosis.

As with pleural mesothelioma symptoms can take years to show. Patients generally suffer from abdominal pain and may have a mass in their abdomen. The symptoms of this type of mesothelioma may also include nausea, weight loss and fever. A lot of these symptoms are similar to symptoms of gastrointestinal issues, which can lead to confusion in diagnosis.

The doctors can detect mesothelioma through examining the patient's medical history and conducting a physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can reveal tumors and other signs of cancer which aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage and recommend treatment options. The stage is determined by the kind of cell and if the tumor has spread.

The most significant mesothelioma risk factor is asbestos exposure. People who have been in occupations that require asbestos, like plumbing manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if a person is not employed in any of these areas, he or she can still be exposed to Asbestos case through family members and other sources. Therefore, anyone who believes they could be at risk should speak to an expert. A mesothelioma specialist can assist those who have a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma accounting for up to 80 percent of cases. Exposure to asbestos can happen as a result of work, military service or by living with someone who works with asbestos lawyer or was previously exposed to doing the same. When exposed to asbestos, particles can be breathed into the lungs and abdomen. The particles cause irritation to the linings, causing cancerous cells to develop in the mesothelium. After asbestos exposure mesothelioma is likely to occur between 15 and 60 years.

Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely to get mesothelioma than people younger or older. This is because mesothelioma usually lasts between 20 and 60 years after the initial time of exposure before cancer symptoms appear. It is important to note, too, that mesothelioma may be present in those who have been exposed to asbestos without having been directly exposed to it. This is known as indirect or secondary exposure to asbestos. It can be just as dangerous as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It can also make it more vulnerable. Mesothelioma is also aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is due to the fact that men are more likely to work with asbestos litigation and experience a more exposure than women. Men are also more likely to have lived with someone who been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos lawsuit on their clothes.

Diagnosis

Mesothelioma is a difficult disease to recognize 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 an examination and write notes on the medical history of a patient including asbestos exposure. Doctors can also request a chest X-ray or CT scan to detect lumps and other abnormalities, and also to look for evidence of previous asbestos exposure such as plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, that uses radio waves and magnets to create a series detailed images of the insides of the body. Another way for doctors to detect mesothelioma is to perform a surgical biopsy. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further testing. A pathologist can then look at the tissue under microscopes to determine whether it has cancerous cells.

Mesothelioma can be classified based on the mesothelial type involved, whether those cells are benign or malignant, and the location of the tumor, its type, and the stage of the cancer. Certain types of mesothelioma may be more likely to develop metastasis or spread which is why it is crucial to get a definite diagnosis so doctors can treat the disease before it goes out of control.

Doctors may also conduct tests in the laboratory on tumors to identify specific genes, proteins or other factors that can help them describe the characteristics of cancer and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. However, it's important to remember that the cancer is treatable, especially in its initial stages. A lot of people suffering from mesothelioma be afflicted for a long time, without spreading.

Exposure to asbestos can trigger mesothelioma through a variety of ways. Asbestos fibers that are tiny enough to be felt or observed by naked eyes are able to become airborne and irritate the lining of the lung (pleura). Over time the irritation can lead to the formation of scar tissue that eventually result in tumors.

The pleura is the area that surrounds the heart and lungs and also the abdomen. Mesothelium consists of cells that react to asbestos legal, causing it to inflame and create scar tissue. These changes eventually lead to malignant mesothelioma tumours.

The symptoms of pleural mesothelioma are breathlessness and chest pain as well as the accumulation of fluid in the lungs (pleural effusion). In rare cases cancer can spread to the tissues around the reproductive organs and the heart.

A doctor will request biopsy if scans show a potential tumor in the lungs or stomach. In the course of the procedure, doctors remove a small amount of fluid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and determine the best treatment plan.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize a combination of these treatments. Patients could also benefit from taking part in a clinical trial of new mesothelioma treatments. To learn more about the trials, patients should speak to mesothelioma specialists who have expertise in treating the condition.
