Mesothelioma and Asbestos

Asbestos is a mineral that naturally occurs in the form of thin, long fibers. People who are exposed to asbestos risk developing lung diseases such as mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma occurs in the outer lung lining, or pleura. It is the most prevalent mesothelioma that accounts for up between 70 and 79% of diagnosed cases. People with this condition experience pain in the chest and breath shortness and may also feel the sensation of weight in the chest.

Exposure to asbestos, a group of minerals comprised of microscopic fibers, typically causes this kind of cancer. Once inhaled, the fibers stick inside the lung and cause irritation that leads to 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 are usually not apparent until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most frequently reported symptoms. Some patients also experience difficulty breathing or chest tightness. People who suffer from this cancer usually have previous exposure to asbestos in the workplace. The most frequent jobs that put people at risk of pleural mesothelioma include manufacturing, construction and shipbuilding. People who were in the military are at a greater risk due to the frequent use of asbestos in Navy vessels and Army bunkers.

The most common staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes and metastases) staging system. The stage that a patient is at upon diagnosis will aid their doctor in determining the best treatment plan for them. Patients who have pleural mesothelioma which is in stage three or four will have a worse prognosis than those in a less advanced stage. Mesothelioma in stage four is usually spread to the liver, diaphragm or even the heart of a patient. This can make it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Contrary to pleural cancer which forms in the lining of the lung, peritoneal cancer develops in the membrane that covers the abdominal cavity, which includes organs like the intestines and liver. Similar to pleural mesothelioma and peritoneal mesothelioma is caused by asbestos exposure. The disease is less common than pleural mesothelioma, and just 300-500 cases being diagnosed each year.

Like pleural mesothelioma, symptoms may take years to appear. Patients typically suffer from abdominal pain and may also have a lump in their abdomen. The symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms are similar to those of digestive problems, which can result in confusion in diagnosis.

The doctors can detect mesothelioma through examining the patient's medical history and conducting a physical exam. They can also use imaging tests such as X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can show cancerous tumors or other symptoms of cancer that aren't visible on an X-ray.

The results of these tests allow doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The stage of the disease is determined based on the type of cells and whether or not the cancer has spread to other areas of the body.

The most significant mesothelioma-related risk factor is asbestos exposure. People who have worked in asbestos-containing occupations, like electrical or plumbing work, or in manufacturing and construction are more likely to contract the disease. Even if someone is not employed in one of these areas, he or she can be exposed to asbestos through family members or other sources. This is why anyone who is concerned that they might be at risk should speak to a doctor. If they have any history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in learning more about the risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, making up as much as 80 percent of all cases. Exposure to asbestos lawyer can occur as a result of military service, work, or living with someone who used to work with asbestos. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. These irritate the linings and cause cancerous cells to form in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop following exposure to asbestos.

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. It takes mesothelioma 20-60 years to manifest cancer symptoms after the first exposure. It is important to remember that mesothelioma may develop in people who were exposed to asbestos case (Highly recommended Site), but did not engage directly with it. This is called secondary or indirect exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma as it damages the mesothelium. It also makes it more prone to. In addition, mesothelioma may be exacerbated by certain illnesses like asbestosis and pneumonia. It is also important to note that mesothelioma occurs more frequently in men than women. This is because men are more likely to work with asbestos and experience a a longer period of exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and to have asbestos-containing fibers on their clothing. Women tend to be less exposed to asbestos claim, and they don't usually bring asbestos home on their clothing.

Diagnosis

Mesothelioma is a difficult disease to recognize because the symptoms are often similar to other conditions. Due to this, patients are often misdiagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination of the body and take note of the medical history of the patient including asbestos exposure. Doctors can also request an X-ray of the chest or CT scan to check for lumps and other abnormalities, and also to look for evidence of past asbestos exposure like plaques on the pleura (thickened pleura with calcium deposits) and the accumulation of fluid between the lung and the chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance image or MRI test, which uses radio waves and magnets in order to create a series detailed images of the insides of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further testing. A pathologist can examine the tissue with microscopes to determine if it has cancerous cells.

The type of mesothelial cell involved and the benign or malignant nature of those cells as well as the location, type and stage of the tumour, are used to classify the disease. Certain mesothelioma types have an increased risk of metastasizing or spreading and it's crucial to get a definitive diagnosis so that doctors can treat it before it gets out of control.

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

Treatment

A diagnosis of mesothelioma can be terrifying. However, it's important to remember that the disease is treatable, especially in its initial stages. Many patients with mesothelioma survive for many years with the disease without it spreading to other areas of their body.

Asbestos exposure can trigger mesothelioma via various mechanisms. asbestos legal fibres, small enough to not be felt or seen by naked eyes are able to become airborne, causing irritation to the lung's lining (pleura). In time irritation leads to formation of scar tissue, which causes changes in the structure of cells that can eventually grow into tumors.

The pleura surrounds the lungs and the heart, as well as the abdomen. Mesothelium is made up of cells that react to asbestos which causes it to become inflamed and develop scar tissue. As time passes, these changes result in the growth of malignant mesothelioma tumors.

The signs of pleural mesothelioma can include breathlessness and chest pain, or a buildup of fluid in the lungs (pleural effusion). In rare cases, the cancer can be spread to the tissues around the heart and reproductive organs.

A doctor will order biopsy if imaging scans reveal a possible tumor in the lungs or stomach. During the procedure, doctors take tiny amounts of tumor or fluid for lab tests. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are a variety of treatment for mesothelioma such as chemotherapy and surgery. The majority of doctors use the combination of these methods. Patients could also benefit from participating in a clinical study of new mesothelioma therapies. Patients can learn more about the trials by consulting a mesothelioma expert who has treated mesothelioma.
