Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally forms in the form of thin, long fibers. People who are exposed to asbestos claim may develop lung diseases like mesothelioma.

It may take decades for symptoms to appear after asbestos claim legal [mouse click the following post] exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the outer lung lining, also known as the pleura. It is the most common type of mesothelioma, making up 70% to 79% of diagnosed cases. People with this condition experience pain in the chest and breath shortness and may also feel the sensation of weight in the chest.

Exposure to asbestos, a class of minerals composed of microscopic fibers, usually causes this kind of cancer. These fibers, when inhaled can cause irritation and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Some patients have coughing problems, trouble breathing or chest tightness. People with this cancer often have previous exposure to asbestos in the workplace. Construction, manufacturing, and shipbuilding are the most common jobs that put people at a high danger of developing pleural melanoma. Individuals who have served in the military are at greater risk due to the widespread use of asbestos in Navy vessels and Army bunkers.

The most common staging system for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at at diagnosis will aid their doctor in determining the best treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or four will suffer a more negative prognosis than those in a lower stage. Mesothelioma in stage four can spread to the liver, heart, or diaphragm. This can make it more difficult to treat and increases the risk of complications for patients.

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 such as the liver and intestines. Like pleural mesothelioma, exposure to asbestos settlement is the cause of peritoneal mesothelioma. There are only 300-500 cases diagnosed annually this is less than pleural asbestosis.

Like pleural mesothelioma, symptoms can take a long time to manifest. Most patients suffer from abdominal pain and abdominal swelling. This kind of mesothelioma can cause nausea, weight loss and fever. Many of these symptoms could be mistaken for gastrointestinal problems and can lead to a false diagnosis.

Doctors can detect mesothelioma by reviewing the medical history of the patient and conducting a physical exam. They can also utilize imaging tests like Xrays, 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, determine the stage and recommend treatment options. The stage is determined by the type of cell as well as whether the tumor has spread.

Asbestos exposure is the biggest risk factor. People who have been in occupations that require asbestos, such as plumbing, manufacturing, electrical work, or construction, are at greater risk of developing the disease. However, even if people do not work in these fields they could be exposed to asbestos through family members or through other sources. Anyone who believes they are at risk should talk to an expert. A mesothelioma specialist can help those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos is the main risk factor for mesothelioma. It is responsible for as much as 80percent of cases. Exposure to asbestos can occur as a result of work, military service, or through living with a person who is exposed to asbestos or used to do the same. Asbestos particles can be inhaled by people who are exposed to it. The particles cause irritation to the linings of the lungs, causing 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 genetics, smoking and aging. The people in their 40s or 50s are at a higher chance of developing mesothelioma to people who are younger or more. Mesothelioma can take between 20 and 60 years to manifest cancer symptoms after the first exposure. It is also important to note that mesothelioma is a possibility in people who were exposed to asbestos but didn't deal with it directly. This is known as secondary or indirect asbestos exposure. It can be as dangerous as direct asbestos exposure.

Smoking increases the chance of mesothelioma developing, because it damages the mesothelium. It also makes it more susceptible. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos and have more exposure than women. Additionally, men are more likely to live with someone who had asbestos exposure and bring asbestos fibers that have escaped home on their clothes. Women are less likely to come in contact with asbestos, and they are less likely to bring asbestos home on their clothes.

Diagnosis

It is difficult to identify mesothelioma since its symptoms are frequently similar to other illnesses. This is why patients are often wrongly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take down a patient's medical history, including asbestos exposure. Doctors will also recommend a CT scan or chest X-ray in order to look for lumps, abnormalities and evidence of exposure to asbestos. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart, and a magnetic resonance imaging, also known as MRI test that uses radio waves and magnets to make 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 piece of tissue from the pleura or peritoneum to conduct further tests. A pathologist can then examine the tissue using a magnifying glass to determine if it is a cancerous cell.

Mesothelioma is classified according to the type of mesothelial cells involved, whether the cells are malignant or benign, and the location of the tumor, its type, and the stage of the cancer. Certain mesothelioma types have greater chance of metastasizing or spreading and it's crucial to determine the type of mesothelioma so doctors can treat it before it gets out-of-control.

Doctors may also conduct tests in the lab on tumors to identify specific genes, proteins or other elements that can help them describe cancer characteristics and determine the best treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. It is important to keep in mind that cancer can be treated especially at its early stages. Many people with mesothelioma live for many years with the disease without it spreading to other organs of their body.

Exposure to asbestos can trigger mesothelioma in a number of ways. Asbestos fibers, which are tiny enough to be felt or observed by naked eyes can be airborne, causing irritation to the lining of the lung (pleura). As time passes irritation leads to formation of scar tissue which causes changes in the cell structure that can eventually grow into tumors.

The Pleura is a covering that surrounds the abdomen, heart, and lungs. Mesothelium consists of cells that react to exposure to asbestos, causing it to inflame and create scar tissue. These changes eventually result in malignant mesothelioma tumors.

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

A doctor will request biopsy if imaging scans show the possibility of a lung tumor or stomach. During the procedure, doctors will remove a small sample of the fluid or tumor for laboratory testing. The results can confirm a mesothelioma diagnosis, and provide the best treatment plan.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. The majority of doctors employ the combination of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma treatment. To find out more, patients should consult mesothelioma experts who have expertise in treating the condition.
