Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally forms in the form of long, thin fibers. Workers who are exposed to asbestos on a regular basis risk developing mesothelioma and other lung diseases of different types.

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

Pleural Mesothelioma

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

Exposure to Asbestos case, a group of minerals composed of microscopic fibers causes this kind of cancer. When inhaled, these fibers are absorbed into the lungs and cause irritation that results in scarring and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural melanoma are chest pain and breath shortness. Some patients have coughing problems, trouble breathing, or chest tightness. Patients with this cancer have a history that includes asbestos attorney exposure at work. The most frequent jobs that put people at risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who were in the military are at greater risk due to the frequent use of asbestos settlement in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most common staging system for the pleural adenocarcinoma. The stage that the patient is in at the moment of diagnosis will determine what treatment plan they should follow. For instance, patients who have mesothelioma that is pleural in stage three or four have a less favorable prognosis than those in lower stages. Stage four mesothelioma often spreads to the diaphragm, liver or even the heart of a patient. This can make it more difficult to treat and raises the likelihood of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma develops in the peritoneum, it is a membrane that lines the abdominal cavity and organs like the intestines and liver. Similar to pleural mesothelioma mesothelioma is caused by asbestos legal exposure. The disease is less prevalent than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take years to show. Patients usually have abdominal pain, and may also have a lump in their abdomen. This type of mesothelioma may cause nausea, weight loss, and fever. A lot of these symptoms are similar to those experienced by digestive problems, which can cause confusion in diagnosis.

Typically, doctors can identify mesothelioma after a thorough medical history and physical exam. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can detect tumors as well as other signs of cancer that are not evident on X-rays.

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

Asbestos exposure is the biggest risk factor. People who have worked in professions that require asbestos, like plumbing manufacturing, electrical work or construction, are at increased risk of developing the disease. Even if someone does not work in one of these areas, he or she can still be exposed through family members and other sources. This is why anyone who believes they could be at risk should talk to an expert. If they have any history of exposure to asbestos or mesothelioma, a specialist can help them find out more about their risk.

Risk Factors

Asbestos is the primary risk factor for mesothelioma. It is responsible for as much as 80percent of cases. Exposure to asbestos can happen through work, military service, or living with people who have worked with asbestos. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. These particles can cause irritation to the linings and trigger cancerous cells to grow in the mesothelium. Following exposure to asbestos mesothelioma is likely to develop between 15 and 60 years old.

Other risk factors include genetics, smoking and aging. People in their 40s and 50s are at greater chance of developing mesothelioma to those who are younger or older. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is also important to note that mesothelioma is a possibility in people who have been exposed to asbestos, but did not deal with it directly. This is called secondary or indirect exposure to asbestos. It could be as hazardous as direct exposure.

Smoking increases a person's chances of getting mesothelioma because it causes mesothelium damage and makes it more prone to asbestos. Mesothelioma can also be caused by certain diseases, such as asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in males than females. This is because 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 been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women are less likely to come in contact with asbestos, and they are less likely to carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are often similar to other conditions. This is why patients are sometimes mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform a physical exam and take notes on the medical history of a patient, including asbestos exposure. Doctors may also request a CT scan or chest X-ray in order to look for lumps, abnormalities, and evidence of asbestos exposure. 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 magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is another method doctors use to diagnose mesothelioma. When a biopsy is performed, doctors remove a tiny part of tissue from the pleura or the peritoneum, to be further examined. A pathologist will then look at the tissue with an magnifying glass to determine if it contains cancerous cell.

Mesothelioma is classified based on the type of mesothelial cells involved, whether the cells are benign or malignant and also the location of the tumor, its type, and the stage of the tumor. Some types of mesothelioma have greater chance of metastasizing or spreading therefore it is essential to establish a clear diagnosis to ensure that the doctors can treat it before it becomes out of control.

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

Treatment

A mesothelioma diagnose can be terrifying. But, it is crucial to remember that the disease is treatable, particularly in its earlier stages. Many patients with mesothelioma survive for years with the disease, without spreading to other areas of their body.

asbestos lawyer exposure can trigger mesothelioma via various mechanisms. Asbestos fibers, too small to detect or feel through the naked eye, can be airborne and cause irritation to the lining of the lungs (pleura). Over time the irritation can lead to the formation of scar tissues, which eventually lead to tumors.

The pleura covers the lungs and heart and also the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos litigation. They cause inflammation of the tissue and cause it to become scarred. As time passes, these changes result in the growth of malignant mesothelioma tumors.

The signs of pleural mesothelioma can include shortness of breath, chest pain or the accumulation of fluid on the lung (pleural effusion). In rare cases, the cancer can be spread to the tissues around the heart and reproductive organs.

A doctor may request a biopsy if imaging scans reveal a possible tumor in the lungs or stomach. The procedure involves the removal of small amounts of fluid or tumor for lab tests. The results can confirm a mesothelioma diagnosis and provide the best treatment option.

There are a variety of treatment for mesothelioma such as chemotherapy and surgery. Most doctors use the combination of these treatments. Patients can also benefit by taking part in a clinical trial of new mesothelioma treatments. To learn more about the trials, patients should speak to a mesothelioma specialist who has experience treating the condition.
