Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that develops in the outer lung lining (pleura). It is the most prevalent mesothelioma type, accounting for up 70 to 79% of all diagnosed cases. Patients with this disease suffer from chest pain and breathlessness and may experience the sensation of weight in the chest.

Exposure to asbestos, a class of minerals composed of microscopic fibers, usually causes this kind of cancer. When inhaled, these fibers can cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs as well as the heart of a person. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and breath shortness. Patients may have coughing problems, trouble breathing, or chest tightness. People with this cancer have a past that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are among the most prevalent occupations that put people at a high risk of developing pleural mesothelioma. Individuals who have served in the military are at greater risk due the widespread use of asbestos case (navigate to this web-site) in Navy vessels and bunkers for the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most common staging system used for pleural adenocarcinoma. The stage that the patient is in at the moment of diagnosis will determine the treatment plan they should follow. Patients with pleural mesothelioma that is in stage three or four will have a worse outlook than those in a less advanced stage. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This makes it more difficult to treat and increase the likelihood of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that develops in the lung lining, peritoneal mesothelioma develops in the peritoneum, a membrane that lines the abdominal cavity as well as organs like the intestines and the liver. Similar to pleural mesothelioma and peritoneal mesothelioma can be caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms may take years to appear. Typically, patients are afflicted with abdominal pain as well as an abdominal mass. Symptoms of this type of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms can be misinterpreted as digestive issues, leading to a false diagnosis.

Typically, doctors can identify mesothelioma through an extensive health history and physical examination. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can identify tumors and other signs of cancer that aren't evident on X-rays.

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

Asbestos exposure is the most important risk factor. People who have been in occupations which require asbestos, such as plumbing electrical work, manufacturing or construction, are at increased risk of developing the disease. Even if an individual is not employed in one of these fields however, they may still be exposed through family members or other sources. For this reason, anyone who suspects they may be at risk should talk to a doctor. If they have an history of exposure to asbestos or mesothelioma, a specialist can assist them in learning more about the risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma, which accounts for as much as 80 percent of all cases. Exposure to asbestos can occur due to work, military service, or by living with someone who is exposed to asbestos or has previously done the same. When exposed to asbestos, the particles can be inhaled into the abdomen and lungs. These particles irritate the linings of the abdomen, which causes 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 more likely be diagnosed with mesothelioma compared to those who are younger or more senior. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to keep in mind, too, that mesothelioma can develop in those who have been exposed to asbestos, but without having been directly exposed to it. This is known as indirect or secondary exposure to asbestos. It could be as hazardous as direct exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it damages the mesothelium and makes it more vulnerable to asbestos. Mesothelioma can also be caused by certain diseases, such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more common for men than women. This is due to the fact that men are more likely to work with asbestos lawsuit and have a longer period of exposure than women. Men are also more likely to have lived with someone who worked with asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come into contact with asbestos and rarely carry asbestos lawyer on their clothes.

Diagnosis

Mesothelioma is a difficult disease to diagnose because the symptoms are often similar to other diseases. Due to this, patients are sometimes wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background including asbestos exposure. Doctors can also order an X-ray chest or CT scan to check for lumps or other abnormalities, and also to look for evidence of past asbestos exposure like plaques on 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, also known as MRI, test, which makes use of radio waves and magnets to make a series of precise images of the inside of the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. A surgical biopsy is when doctors take a small amount of tissue from the pleura or peritoneum for further testing. A pathologist then examines the tissue under a magnifying glass to determine whether it contains cancerous cell.

The mesothelial type involved and the benign or malignant nature of these cells and the location and stage of the cancer are used to categorize the disease. Some types of mesothelioma have an increased risk of spreading or metastasizing therefore it is essential to determine the type of mesothelioma to ensure that the doctors can treat it before it gets out-of-control.

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

Treatment

A diagnosis of mesothelioma can be a frightening prospect. However, it is important to remember that the disease can be treated, particularly in its earlier stages. Many patients with mesothelioma survive for years with the disease without it spreading to other parts of their body.

Asbestos exposure can cause mesothelioma through many mechanisms. Asbestos fibers that are tiny enough to be felt or seen with the naked eyes are able to become airborne, irritating the lining of the lung (pleura). As time passes, the irritation leads to the formation of scar tissues and eventually tumors.

The pleura covers the lungs and heart, as well as the abdomen. Mesothelium is made up of cells that react to asbestos claim and cause it to enflame and form scar tissue. In time, these changes can result in the growth of malignant mesothelioma tumors.

Breathing problems, chest pain or fluid accumulation on the lungs are all symptoms of the pleural msothelioma. In rare instances cancer may spread to the tissues around the reproductive organs as well as the heart.

If imaging scans reveal an area of concern in the stomach or lungs the doctor will request biopsies. During the procedure, doctors take tiny amounts of fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma and determine the best treatment option.

There are a variety of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors rely on the combination of these methods. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. To learn more, patients should consult a mesothelioma specialist who has experience treating the condition.
