Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of thin, long fibres. Workers who are exposed to asbestos regularly are at risk of developing mesothelioma or other types of lung diseases.

It can take years before symptoms begin to manifest after exposure to asbestos. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that develops in the outer lung liner (pleura). It is the most common type of mesothelioma, making up 70 to 79% of all diagnosed cases. The condition can cause chest discomfort, shortness of breath, and a feeling of heaviness.

This type of cancer typically caused by exposure to asbestos, which is a cluster of minerals that are made up of microscopic fibres. Once inhaled, the fibers cling to the lung and cause irritation which results in scarring and DNA mutations. Pleura is the lining of both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

Shortness of breath and chest pain are the most frequent symptoms. Some patients also experience coughing, difficulty breathing, or chest tightness. People with this cancer have a past that includes asbestos exposure at work. Manufacturing, construction and shipbuilding are the most common occupations that put people at high chance of developing pleural mesothelioma. People who were in the military are at a greater risk due the widespread use of asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most popular staging system used to treat the pleural adenocarcinoma. The stage the patient is in at the moment of diagnosis will determine the treatment plan they should follow. Patients who have pleural mesothelioma which is in stage three or four will have a worse outlook than those who are in a less advanced stage. Stage four mesothelioma often spreads to the liver, diaphragm and/or a person's heart. This could make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum - an elongated membrane that covers the abdominal cavity and organs like the intestines and the liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma. There are only about 300-500 cases diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to manifest. Patients typically have abdominal pain, and could also experience a mass in their abdomen. This type of mesothelioma may cause nausea, weight loss and fever. Many of these symptoms are similar to those experienced by digestive problems, which can cause confusion in diagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and conducting a physical exam. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can reveal tumors and other signs of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma and determine the stage. They can also recommend treatment options. The staging is determined by the cell type and whether or the cancer has spread to other regions of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have worked in asbestos-containing professions, such as electrical or plumbing work, or in manufacturing and construction are more likely to contract the disease. Even if they aren't employed 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 a doctor. A mesothelioma specialist can help those with a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos exposure is the primary mesothelioma risk factor, accounting for up to 80 percent of all cases. Exposure to asbestos can occur due to military service, work or living with people who have worked with asbestos legal (click through the up coming webpage). asbestos attorney particles can be breathed in by those who are exposed to asbestos. These particles irritate the linings of the abdomen, which causes cancerous cells to develop in the mesothelium. Following exposure to asbestos mesothelioma can develop between 15 and 60 years.

Other risk factors include genetics, smoking and aging. People in their 40s and 50s are more at risk of developing mesothelioma as compared to those who are younger or older. It takes mesothelioma between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is also important to know that mesothelioma may develop in those who were exposed to asbestos but did not engage directly with it. This is known as indirect or secondary exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more prone to. Mesothelioma can also be caused by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than females. Men are more likely than women to have been exposed to asbestos for a longer time and to work with asbestos attorney for longer periods of time. Also, men are more likely to live with someone who has was exposed to asbestos and bring stray asbestos fibers home on their clothing. Women tend to be less exposed to asbestos, and they don't usually carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms often resemble other conditions. Due to this, patients are sometimes wrongly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors can also order an X-ray chest or CT scan to check for lumps or other abnormalities, and also to look for evidence of previous asbestos exposure such as pleural plaques (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance imaging or MRI test, which uses magnets and radio waves in order to create a series detailed images of the insides of the body. Another way for doctors to detect mesothelioma is through a surgical biopsy. During a surgical biopsy, doctors remove a small piece of tissue from the pleura or peritoneum for further testing. A pathologist is then able to examine the tissue under microscopes to determine if it has cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether the cells are malignant or benign and also the location, type, and stage of the cancer. Some types of mesothelioma are more likely to spread or metastasize which is why it is crucial to get a definite diagnosis so that doctors can treat the disease before it gets out of control.

Doctors may also conduct tests in the lab on a tumor to identify particular proteins, genes, or other factors which can help them identify the characteristics of cancer and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be frightening. It is crucial to remember, however, that cancer can be treated especially at its early stages. Many people with mesothelioma live for many years without the disease spreading to other parts of their body.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos fibers, which are too small to be able to see or feel with the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time irritation can lead to formation of scar tissue which causes changes in the structure of cells that can eventually grow into tumors.

The Pleura is a protective layer that surrounds the abdomen, heart, and lungs. Mesothelium consists of cells that react to exposure to asbestos which causes it to become inflamed and form scar tissue. As time passes, these changes cause the development of malignant mesothelioma tumors.

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

If scans of imaging reveal an area of concern in the stomach or lungs the doctor will request a biopsies. During the procedure, doctors take a small sample of the fluid or tumor for lab testing. The results can confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. The majority of doctors employ combinations of these treatments. Patients can also benefit by enrolling in a clinical trial of new mesothelioma treatment. To learn more about the trials, patients should consult a mesothelioma specialist who has had experience treating the disease.
