Mesothelioma and Asbestos

asbestos case (reviews over at Koshop), a natural mineral, naturally forms in the form of long, thin fibers. People who are exposed to asbestos on a regular basis are at risk of developing mesothelioma as well as other lung diseases.

It could take a long time for symptoms to show up after asbestos exposure. Different asbestos settlement types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the lung's outer lining (pleura). It is the most prevalent mesothelioma form and accounts for 70% to 79% all diagnosed cases. This condition causes chest pain, shortness of breathe and a feeling heaviness.

Exposure to asbestos, a class of minerals made of microscopic fibers, typically causes this type of cancer. Once inhaled, these fibers cling to the lung and cause irritation that results in scarring and DNA mutations. Pleura covers both the chest cavity as well as the lungs, 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 common symptoms. Some patients may also experience chest tightness, coughing or difficulty breathing. People with this cancer have a past that includes asbestos exposure at work. The most frequent jobs that expose workers to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. People who have served in the military could be at a higher risk due to the frequent asbestos use in Navy ships and bunkers used by the army.

The most common staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient is in upon diagnosis will assist their doctor in determining the best treatment plan for them. Patients who have pleural mesothelioma which is in stage three or stage four will suffer a more negative prognosis compared to those in a lower stage. Stage four mesothelioma may be spread to the heart, liver or diaphragm. This makes it more difficult to treat and raises the risk of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that is a lung-lining cancer, peritoneal mesothelioma is found in the peritoneum -- it is a membrane that lines the abdominal cavity as well as organs such as the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. There are only 300-500 cases diagnosed annually this is less than the pleural asbestosis.

Like pleural mesothelioma, the symptoms can take years to show. Patients usually have abdominal pain, and could also experience 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 can be misinterpreted as gastrointestinal issues which can lead to a misdiagnosis.

The doctors can detect mesothelioma through looking over the medical history of the patient and conducting a physical exam. Imaging tests like X-rays or CT scans can be used to detect mesothelioma. These tests can reveal tumors and other signs 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 stage is determined by the type of cell as well as whether the tumor has spread.

The most important mesothelioma risk factor is exposure to asbestos. People who have worked in jobs which require asbestos, such as plumbing or manufacturing, electrical work, or construction, are at greater risk of developing the disease. Even if someone is not employed in one of these fields however, they may still be exposed through family members and other sources. Therefore, anyone who suspects they may be at risk should speak to a doctor. A mesothelioma specialist can help those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma, making up as much as 80 percent of cases. Exposure to asbestos may occur through military service, work, or living with people who have worked with asbestos. When exposed to asbestos lawyer, particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings and cause cancerous cells to grow in the mesothelium. After asbestos exposure, mesothelioma may develop between 15 and 60 year.

Other risk factors include smoking, genetics, and the advancing 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 remember that mesothelioma can develop in those who were exposed to asbestos but didn't work with it directly. This is called indirect or secondary exposure to asbestos compensation, and it is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It can also make it more vulnerable. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in men than women. This is due to the fact that men are more likely to work with asbestos and have more exposure than women. Men are also more likely to have lived with someone who had worked with asbestos and to have asbestos-containing fibers on their clothing. Women tend to have less contact with asbestos and do not typically carry asbestos around on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma since its symptoms are often similar to other conditions. This could lead to patients being wrongly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take down a patient's medical history, including asbestos exposure. Doctors may also request a CT scan or chest X-ray to check 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 heart and blood vessels and magnetic resonance imaging, also known as MRI, test that uses magnets and radio waves to create precise images of the inside of the body. Another method doctors use to diagnose mesothelioma is to perform the procedure of a surgical biopsy. In a surgical biopsy doctors take a small amount of tissue from the peritoneum or pleura to conduct further tests. A pathologist then examines the tissue with a magnifying glass to determine if it is a cancerous cells.

The type of mesothelial cell involved, the malignant or benign nature of those cells as well as the location and stage of the tumour, are used to categorize the disease. Certain mesothelioma types have a higher risk of metastasizing or spreading, so it's important to get a definitive diagnosis so doctors can treat it before it gets out-of-control.

Doctors can also perform laboratory tests on tumors to identify specific genes, proteins or other elements that will help them identify cancer characteristics and determine the best treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to remember that cancer can be treated, particularly in its early stages. Many mesothelioma patients live for many years with the disease, without spreading to other areas of their body.

Exposure to asbestos may cause mesothelioma in many ways. Asbestos fibers that are tiny enough to be felt or viewed by naked eyes are able to become airborne, causing irritation to the lung's lining (pleura). As time passes the irritation can lead to the formation of scar tissue that eventually result in tumors.

The pleura surrounds the heart and lungs and also the abdomen. Mesothelium consists of cells that respond when exposed to asbestos litigation. They inflame the tissue and cause it to become scarred. These changes can lead to malignant mesothelioma tumours.

Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all signs of the pleural msothelioma. In rare cases cancer can spread to the tissues around the reproductive organs and heart.

If imaging scans reveal an underlying mass in the lungs or stomach, a doctor will order a biopsies. During the procedure, doctors remove small amounts of the fluid or tumor for lab analysis. The results will confirm a mesothelioma diagnosis, and indicate the best treatment option.

There are several types of mesothelioma treatment, including surgery, chemotherapy and immunotherapy. Most doctors rely on an amalgamation of these techniques. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. Patients can learn more by speaking with a mesothelioma doctor who has treated the condition.
