Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

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

This type of cancer usually caused by exposure to asbestos which is a grouping of minerals that are comprised of microscopic fibres. When inhaled, these fibers are absorbed into the lung and cause irritation that results in scarring and DNA mutations. The pleura covers the lungs and chest cavity, so these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most common symptoms of pleural melanoma are chest pain and breath shortness. Some patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. People with this cancer have a past that includes asbestos attorney exposure at work. Manufacturing, construction and shipbuilding are the most prevalent jobs which put people at risk chance of developing pleural mesothelioma. Individuals who have served in the military are at a higher risk due to the extensive use asbestos in Navy vessels and bunkers for the Army.

The most popular staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage a patient is in at the moment of diagnosis will determine the treatment plan they will receive. Patients who have pleural mesothelioma which is in stage three or four will have a worse prognosis compared to those in a less advanced stage. Stage four mesothelioma often spreads to the diaphragm, the liver or even the heart of a patient. This can make it more difficult to treat and raises the likelihood of complications for patients.

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 and organs such as the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the primary reason for peritoneal msothelioma. It is estimated that only 300-500 cases are diagnosed each year this is less than pleural asbestosis.

As with pleural asbestosis symptoms can take a long time to manifest. The majority of patients experience abdominal pain and a mass in the abdomen. This kind of mesothelioma can also cause nausea, weight loss, and fever. Many of these symptoms could be misinterpreted as gastrointestinal issues which can lead to a mistaken diagnosis.

Generally speaking, doctors can detect mesothelioma through an exhaustive health history and physical exam. They can also utilize imaging tests such as X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can detect tumors and other signs of cancer that are not evident on X-rays.

These tests enable doctors to identify mesothelioma, and determine the stage. They can also suggest treatments. The stage of the disease is determined based on the cell type and whether or not the cancer has spread to other regions of the body.

asbestos settlement exposure is the biggest risk factor. People who have worked in professions which require asbestos, such as plumbing, manufacturing, electrical work or construction, are at greater risk of developing the disease. However, even if individuals do not work in these fields, they can still be exposed to asbestos through family members or through other sources. This is why anyone who believes they could be at risk should speak to an expert. If they have a history of asbestos exposure and mesothelioma is a concern, a specialist will assist them in finding out more about the risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It accounts for as much as the 80% of cases. Exposure to asbestos can happen as a result of military service, work, or living with someone who used to work with asbestos. Asbestos particles can be breathed in by people who are exposed to asbestos. These irritate the linings and cause 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 age. People in their 40s or 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 were exposed to asbestos but didn't deal with it directly. This is called secondary or indirect exposure to asbestos. It can be just as dangerous as direct exposure.

Smoking increases the risk of mesothelioma, since it damages mesothelium. It also makes it more prone to. Mesothelioma is also aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to note that mesothelioma is more prevalent for men than women. This is because men are more likely to be exposed to asbestos and endure a an extended period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to carry asbestos fibers on their clothing. Women tend to be less in contact with asbestos, and they don't usually carry asbestos lawyer on their clothes.

Diagnosis

Mesothelioma is a difficult disease to diagnose because the symptoms often resemble other diseases. This can result in patients being misdiagnosed.

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

Other diagnostic tests include a magnetic resonance image or MRI test, which uses magnets and radio waves to create a series of detailed images of the insides of the body. Another way doctors can diagnose mesothelioma is through an operation called a biopsy. When a biopsy is performed doctors will remove a small piece of tissue from pleura or the peritoneum, to be tested further. A pathologist can examine the tissue with a microscope to see if it contains cancerous cells.

Mesothelioma is classified based on the mesothelial type involved, whether the cells are benign or malignant and the location, type, and stage of the cancer. Some types of mesothelioma are more likely to grow or spread which is why it is crucial to get a definite diagnosis to ensure that doctors are able to treat the disease before it goes out of control.

Doctors can also perform tests in the lab on tumors to identify specific genes, proteins, or other factors which can help them describe the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. But, it is crucial to keep in mind that the cancer can be treated, particularly in its early stages. Many mesothelioma patients live for many years with the disease without it spreading to other areas of their body.

Exposure to asbestos can cause mesothelioma in a number of ways. Asbestos fibers, which are tiny enough to be felt or observed by naked eyes are able to become airborne and irritate the lining of the lung (pleura). As time passes the irritation causes the formation of scar tissue and eventually tumors.

The pleura is the area that surrounds the heart and lungs and also the abdomen. Mesothelium consists of cells that react when exposed to asbestos. They inflame the tissue and cause it to become scarred. These changes eventually result in malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathing problems and chest pain, or a buildup of fluid on the lungs (pleural effusion). In rare instances, cancer can spread into the tissues surrounding the reproductive organs and the heart.

If imaging scans show an underlying mass in the lungs or stomach, a doctor will order biopsies. During the procedure, doctors take a small sample of the fluid or tumor for laboratory analysis. The results will confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are several types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. Most doctors use the combination of these treatments. Patients may also benefit from participating in a clinical study of new mesothelioma treatment. To learn more about the trials, patients should speak to mesothelioma specialists who have had experience treating the disease.
