Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in thin, long fibres. People who are regularly exposed to asbestos are at risk of developing lung diseases, such as mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung lining (pleura). It is the most frequent mesothelioma that accounts for up 70 to 79% of diagnosed cases. Patients with this disease feel chest pain and breathlessness and may experience an ache or heaviness in the chest.

This type of cancer usually caused by exposure to asbestos, which is a grouping of minerals that are comprised of microscopic fibres. Once inhaled, these fibers are absorbed into the lung and cause irritation which leads to scarring and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also feel tightness in their chest and coughing, or breathing difficulties. People with this cancer have a history of disease that includes asbestos exposure at work. Manufacturing, construction, and shipbuilding are the most common occupations that put people at high chance of developing pleural mesothelioma. People who were in the military are at a greater risk due the widespread use of asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most commonly used staging system used to treat the pleural adenocarcinoma. The stage that the patient is in at the moment of diagnosis will determine what treatment plan they should follow. For example, patients with mesothelioma pleural stage three or four have a less favorable prognosis than those with a lower stage. Stage four mesothelioma may develop into the heart, liver or diaphragm. 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 is found in the lung's lining, peritoneal cancer develops in a membrane that surrounds the abdominal cavity, including organs like the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the cause of peritoneal msothelioma. Only 300-500 cases are diagnosed each year this is less than pleural asbestosis.

As with pleural asbestosis symptoms can take years to manifest. Patients generally suffer from abdominal pain and could also experience a mass in their abdomen. This type of mesothelioma may cause nausea, weight loss and fever. Many of these symptoms are similar to those experienced by digestive issues, which could cause incorrect diagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and performing a physical exam. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can show tumors, as well as other indications of cancer that aren't apparent on an X-ray.

These tests enable 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 the cancer has spread to other regions of the body.

Asbestos exposure is the most important risk factor. People who have worked in asbestos-containing jobs, such as plumbing or electrical work, or in manufacturing and construction are more likely to contract the disease. Even if someone isn't employed in one of these areas however, they may still be exposed through family members and other sources. Anyone who thinks they're at risk should speak with an expert. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about their risk.

Risk Factors

asbestos litigation is the primary risk factor for mesothelioma. It is responsible for as much as 80% of all cases. Exposure to asbestos 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. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and aging. People in their 40s and 50s are more likely be diagnosed with mesothelioma compared to those who are younger or older. It takes mesothelioma between 20 and 60 years to manifest cancer symptoms after the first exposure. It is also important to note that mesothelioma can develop in those who were exposed to asbestos, but did not engage directly with it. This is referred to as secondary or indirect exposure to asbestos settlement and it could be as hazardous as direct exposure.

Smoking can increase the likelihood of developing mesothelioma due to the fact that it damages the mesothelium, which makes it more susceptible to asbestos. Mesothelioma can also be caused by certain illnesses 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 compensation and experience a a longer period of exposure than women. Additionally, men are more likely to live with someone who has had asbestos exposure and bring asbestos fibers that have escaped home on their clothing. Women are less likely to come into contact with asbestos and do not typically carry asbestos home on their clothes.

Diagnosis

Mesothelioma is difficult to identify because the symptoms are often similar to other conditions. This can result in patients being incorrectly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take notes on the medical history of a patient which includes asbestos exposure. Doctors can also request an X-ray chest or CT scan to look for lumps and other abnormalities and also to look for evidence of asbestos exposure in the past like pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test that uses radio waves and magnets to create precise images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform the procedure of a surgical biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum, to be further examined. A pathologist can examine the tissue under microscopes to determine if it has cancerous cells.

Mesothelioma is classified according to the type of mesothelial cells involved, whether these cells are benign or malignant, and the location, type, and stage of the tumor. Some types of mesothelioma have greater chance of metastasizing or spreading and it's crucial to get a definitive diagnosis so that doctors can treat it before it becomes out of control.

Doctors may also conduct laboratory tests on tumors to determine specific genes, proteins or other elements that will help them identify cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is important to remember that cancer can be treated, particularly in its initial stages. Many people with mesothelioma can be afflicted for a long time without spreading.

Exposure to asbestos can trigger mesothelioma in a number of ways. Asbestos fibers, which are too small to see or feel through the naked eye, can become airborne and cause irritation to the lung's lining (pleura). In time, the irritation leads to the formation of scar tissue that eventually result in tumors.

The Pleura is a covering that covers the lungs, heart and abdomen. Mesothelium is made up of cells that react when exposed to asbestos. They cause inflammation of the tissue and cause it to become scarred. In time, these changes can result in the growth of malignant mesothelioma cancers.

A shortness of breath, chest discomfort or fluid buildup on the lungs are all signs of the pleural msothelioma. In rare cases cancer can spread to the tissues surrounding the reproductive organs and the heart.

A doctor may request biopsy if scans show a potential tumor in the lungs or stomach. The procedure involves the removal of small amounts of liquid or tumor for tests in the laboratory. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize an amalgamation of these techniques. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. Patients can find out more by consulting a mesothelioma specialist who has treated the disease.
