Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that affects the outer lung the lining (pleura). It is the most common type of mesothelioma, making up 70 to 79% of all diagnosed cases. Patients suffering from this condition feel chest pain and breath shortness and may also feel an ache or heaviness in the chest.

This type of cancer often caused by exposure to asbestos which is a grouping of minerals comprised of microscopic fibres. When inhaled, these fibers can cause irritation 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 usually doesn't show symptoms until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural melanoma are chest pain and shortness of breath. Patients may also feel tightness in their chest or coughing. They may also experience difficulty breathing. People with this cancer often have an history of exposure to asbestos in the workplace. The most prevalent jobs that expose workers to the risk of pleural mesothelioma include manufacturing, construction and shipbuilding. Individuals who have been in the military are at an especially high risk due to the frequent asbestos use in Navy vessels and army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most common staging system used for pleural adenocarcinoma. The stage a patient is in at diagnosis will help their doctor determine the most effective treatment plan for them. Patients who have pleural mesothelioma which is in stage three or stage four will have a less favorable outlook than those who are in a less advanced stage. Stage four mesothelioma can develop into the liver, heart or diaphragm. This can make it more difficult to treat and raises the chance of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, 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. Similar to pleural mesothelioma, asbestos exposure is the primary reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to show. Patients typically have abdominal pain, and may have a mass in their abdomen. The symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms can be mistaken for gastrointestinal problems and can lead to a misdiagnosis.

The doctors can detect mesothelioma through looking over the medical history of the patient and performing a physical examination. They can also utilize imaging tests like X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors, as well as other signs of cancer that aren't apparent on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. The stage is determined by the kind of cell and if the cancer has spread.

The most important mesothelioma risk factor is asbestos lawsuit exposure. People who have worked in jobs that involve asbestos compensation, such as 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 be exposed to asbestos through family members and other sources. Anyone who believes they may be at risk should talk to a doctor. A mesothelioma expert can help those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the most significant mesothelioma-related risk factor. It accounts for up to 80% of all cases. Exposure to asbestos may occur through work, military service, or by living with someone who works with asbestos or was previously exposed to doing so. When exposed to asbestos, the particles can be breathed into the abdomen and lungs. These irritate the linings and trigger cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos settlement.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or older. This is because mesothelioma usually takes 20 to 60 years from the first exposure to asbestos before symptoms of cancer begin to manifest. It is important to remember that mesothelioma may develop in people who have been exposed to asbestos, but did not deal with it directly. This is known as secondary or indirect exposure to asbestos and it can be just as dangerous as direct exposure.

Smoking increases the risk of developing mesothelioma since it damages the mesothelium and makes it more vulnerable to asbestos. Mesothelioma can also be caused by certain diseases, such as 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. Additionally, men are more likely to live with someone who worked with asbestos and carry asbestos fibers from their workplace on their clothing. Women are less likely to be exposed to asbestos and don't typically carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other diseases. This could lead to patients being wrongly diagnosed.

NYU Langone doctors will perform physical examinations and document the patient's medical background including asbestos exposure. Doctors will also recommend an CT scan or chest X-ray to check for lumps, abnormalities and evidence of exposure to asbestos case (mouse click the up coming post). These include pleural plaques, thickened pleura and calcium deposits.

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test, which uses magnets and radio waves to create detailed images of the interior of the body. A surgical biopsy is a different method for doctors to identify mesothelioma. In a surgical biopsy doctors remove a small piece of tissue from the pleura or peritoneum to conduct further tests. A pathologist is then able to examine the tissue under microscopes to determine if it contains cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cell involved, whether these cells are malignant or benign, and the location of the tumor, the type, and the stage of the tumor. Certain mesothelioma types have a higher risk of spreading or metastasizing, so it's important to establish a clear diagnosis to ensure that the doctors can treat it before it gets out of control.

Doctors can also perform tests in the laboratory on tumors to identify specific proteins, genes or other factors that can aid in describing cancer characteristics and plan treatment. These results are called staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is crucial to remember, however, that cancer can be treated especially at its early stages. Many people with mesothelioma can live with the disease for a long time, without spreading.

Exposure to asbestos can trigger mesothelioma through a variety of ways. Asbestos fibers that are tiny enough to be felt or viewed through the naked eye are able to become airborne and irritate the lining of the lung (pleura). In time, the irritation causes the formation of scar tissue, which leads to changes in the structure of cells that can eventually grow into tumors.

The pleura is the area that surrounds the lungs and heart and also the abdomen. Mesothelium is composed of cells that react to exposure to asbestos which causes it to become inflamed and form scar tissue. Overtime, these changes lead to the development of malignant mesothelioma cancers.

Shortness of breath, chest pain or fluid accumulation on the lungs are all signs of pleural msothelioma. In rare instances, cancer can spread into the tissues around the reproductive organs and heart.

A doctor will request a biopsy if imaging scans reveal a possible tumor in the lungs or stomach. During the procedure, doctors remove a small sample of the fluid or tumor for laboratory tests. The results can confirm a mesothelioma diagnosis and indicate the best treatment plan.

There are a variety of mesothelioma treatments, including surgery, chemotherapy and immunotherapy. Most doctors utilize a combination of these methods. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatment. Patients can find out more by consulting a mesothelioma specialist who has treated mesothelioma.
