Mesothelioma and Asbestos

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

It may take decades for symptoms to show up after asbestos lawyer exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that occurs in the lung's outer lining (pleura). It is the most prevalent mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. People with this condition experience pain in the chest and breath shortness, and they may feel an ache or heaviness in the chest.

This type of cancer is often caused by exposure to asbestos which is a cluster of minerals composed of microscopic fibers. These fibers, when inhaled, cause irritation and DNA mutations. Pleura surrounds both the chest cavity and the lungs, so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma include chest pain and breath shortness. Some patients also experience coughing, difficulty breathing or chest tightness. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. Construction, manufacturing and shipbuilding are among the most common occupations that put people at high danger of developing pleural melanoma. People who have worked in the military could be at an especially high risk due to the frequent use of asbestos in Navy ships and army bunkers.

The most common staging system for pleural mysothelioma has been the TNM (tumor, lymph nodes and metastases) staging system. The stage that a patient is at at diagnosis will assist their doctor in determining the most appropriate treatment plan for them. For instance, patients suffering from a pleural mesothelioma in stage three or four have a less favorable prognosis than patients with lower stages. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This could make the cancer more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum, it is a membrane that lines the abdominal cavity as well as organs such as the intestines and liver. As with pleural mesothelioma exposure to asbestos is the cause of peritoneal mesothelioma. The disease is less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, symptoms can take years to show. Typically, patients suffer from abdominal pain and abdominal swelling. Symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms can be misinterpreted as gastrointestinal issues and can lead to a mistaken diagnosis.

Doctors can detect mesothelioma by reviewing the medical history of the patient and performing a physical examination. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can reveal tumors and other cancer signs that are not evident on X-rays.

These tests enable doctors to diagnose mesothelioma, identify the stage and recommend treatment options. The stage of the disease is determined based on the cell type and whether or the cancer has spread to other areas of the body.

Asbestos exposure is the main risk factor. People who have worked in asbestos-related occupations, like plumbing or electrical work, or in manufacturing and construction, are more likely to contract the disease. Even if an individual does not work in one of these areas, he or she can be exposed to asbestos through family members and other sources. Anyone who suspects that they're at risk should consult a doctor. If they have any history of exposure to asbestos, a mesothelioma specialist can assist them in learning more about the risk.

Risk Factors

Asbestos is the main mesothelioma-related risk factor. It accounts for up to 80percent of cases. Exposure to asbestos may occur through work, military service or through living with a person who works with asbestos or used to do such. When exposed to asbestos, the particles are able to be inhaled into lungs and abdomen. They can cause irritation to the linings of the abdomen and can cause cancerous cells to develop in the mesothelium. Mesothelioma may take 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 at greater risk of developing mesothelioma compared to those younger or older. This is because mesothelioma typically occurs between 20 and 60 years from the first exposure to asbestos before the first signs of cancer appear. It is also important to note that mesothelioma is a possibility in people who were exposed to asbestos, but did not deal with it directly. 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 getting mesothelioma because it damages the mesothelium and makes it more vulnerable to asbestos. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos case (Read Homepage) for longer periods of time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos fibers on their clothing. Women are less likely to come into contact with asbestos and do not typically carry asbestos legal home on their clothes.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being often similar to other diseases. This could lead to patients being misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical history including asbestos attorney exposure. Doctors may also request a CT scan or chest X-ray to look for lumps, abnormalities, and evidence of exposure to asbestos. These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart and magnetic resonance imaging, also known as MRI test that uses magnets and radio waves to make a series of detailed images of the inside of the body. Another way for doctors to detect mesothelioma is by performing an operation called a biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be further examined. A pathologist is then able to look at the tissue under a microscope to see if it contains cancerous cells.

The type of mesothelial cell involved, the malignant or benign nature of those cells and the location the cancer, its type and the stage of the tumor, are used to categorize the disease. Some types of mesothelioma have greater risk of spreading or metastasizing, so it's important to establish a clear diagnosis so doctors can treat it prior to it becoming out-of-control.

Doctors may also conduct tests in the laboratory on a tumor to find specific proteins, genes, or other factors that can help them describe the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is important to keep in mind that cancer can be treated particularly in its initial stages. Many patients with mesothelioma endure the disease for a long time, without spreading.

Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibres, tiny enough to be felt or seen with the naked eyes can be airborne and irritate the lining of the lung (pleura). Over time, the irritation leads to the formation of scar tissues and eventually tumors.

The pleura is a protective covering that protects the abdomen, heart, and lungs. Mesothelium consists of cells that react when exposed to asbestos. They inflame the tissue and cause it to become scarred. Overtime, these changes cause the development of malignant mesothelioma tumors.

Shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all symptoms of the pleural mesothelioma. In rare cases cancer may spread to the tissues surrounding the reproductive organs and heart.

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

There are many types of mesothelioma treatment options, including chemotherapy, surgery and immunotherapy. Most doctors utilize combinations of these treatments. Participating in clinical trials for mesothelioma treatments that are new could be beneficial to patients. Patients can learn more about the trials by speaking with a mesothelioma doctor who has treated mesothelioma.
