Mesothelioma and Asbestos

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

It could take a long time for symptoms to show up after asbestos exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining also known as pleura. It is the most common form of mesothelioma and accounts for 70% to 79% of diagnosed cases. Patients with this disease suffer from chest pain and breathlessness and may experience an ache or heaviness in the chest.

Exposure to asbestos, a family of minerals comprised of microscopic fibers, typically causes this kind of cancer. The fibers, when inhaled can cause irritation and DNA mutations. Pleura surrounds both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also suffer from chest tightness, coughing or difficulty breathing. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. The most prevalent jobs that expose workers to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who served in the military are at higher risk due to the widespread use of asbestos case - Going at Mmatycoon, in Navy vessels and bunkers for the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most common staging system used to treat pleural adenocarcinoma. The stage that the patient is in at the time of diagnosis can help determine the treatment plan they should follow. Patients suffering from pleural mesothelioma who is in stage three or stage four will suffer a more negative outlook than those in a less advanced stage. Mesothelioma in stage four is usually spread to the diaphragm, liver or even the heart of a patient. This makes the cancer more difficult to treat, and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum, a membrane that lines the abdominal cavity as well as organs such as the intestines and the liver. Like pleural mesothelioma, exposure to asbestos is the reason for peritoneal msothelioma. The disease is much less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take years to show. The majority of patients experience abdominal pain and abdominal swelling. The symptoms of this kind of mesothelioma could also include nausea, weight loss and fever. A lot of these symptoms are similar to those of digestive issues, which could lead to misdiagnosis.

Generally, doctors can find mesothelioma after an extensive health history and physical examination. They can also use imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can reveal tumors and other cancer signs that aren't evident on X-rays.

These test results allow doctors to diagnose mesothelioma, determine the stage and recommend treatment options. The stage is determined by the type of cell and whether the cancer has spread.

Asbestos exposure is the most important risk factor. People who have been exposed to asbestos in professions, such as electrical or plumbing work or in manufacturing and construction, are more likely to develop the disease. Even if an individual does not work in any of these areas, he or she can be exposed to asbestos claim through family members or other sources. This is why anyone who believes they could be at risk should talk to an expert. A mesothelioma specialist can help those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is a major risk factor for mesothelioma making up as much as 80 percent of cases. Exposure to asbestos may occur as a result of work, military service, or by living with a person who is exposed to asbestos or has previously done the same. When exposed to asbestos, particles can be breathed into the lungs and abdomen. These particles can cause irritation to the linings and cause cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and age. The people in their 40s or 50s are at a higher risk of developing mesothelioma as compared to those younger or older. This is because mesothelioma typically lasts between 20 and 60 years from the first time of exposure before symptoms of cancer begin to manifest. It is important to keep in mind that mesothelioma could develop in those who have been exposed to asbestos without having directly worked with it. This is referred to as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium, which 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 women. This is because men are more likely to be exposed to asbestos and endure a more exposure than women. Men are also more likely to have lived with someone who had been exposed to asbestos, and to have asbestos fibers on their clothing. Women are less likely to come in contact with asbestos, and they don't usually bring asbestos legal home on their clothes.

Diagnosis

Mesothelioma is difficult to diagnose because the symptoms can be similar to other conditions. Due to this, patients are often misdiagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write down a patient's medical history including asbestos exposure. Doctors may also request an CT scan or chest X-ray to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance scan, or MRI test, that uses magnets and radio waves in order to create a series detailed images of inside the body. Another method doctors use to diagnose mesothelioma is to perform the procedure of a surgical biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the peritoneum or pleura to conduct further tests. A pathologist can then examine the tissue under an magnifying glass to determine if it is a cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether those cells are benign or malignant, and the location of the tumor, the type, and the stage of the tumor. Some types of mesothelioma have greater risk of metastasizing or spreading and it's crucial to get a definitive diagnosis so doctors can treat it before it gets out-of-control.

Doctors may also conduct laboratory tests on tumors in order to determine specific proteins, genes or other factors that can aid in describing cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be frightening. But, it is crucial to remember that the disease can be treated, particularly in its earlier stages. Many people with mesothelioma can endure the disease for a long time without spreading.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos fibers, which are tiny enough to be felt or viewed through the naked eye can be airborne, irritating the lining of the lung (pleura). As time passes, the irritation leads to the formation of scar tissues and eventually tumors.

The pleura is the area that surrounds the lungs and heart and also the abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They cause inflammation of the tissue and cause it to scar. These changes can eventually lead to malignant mesothelioma tumours.

Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all signs of pleural mesothelioma. In rare instances, the cancer can spread to the tissues surrounding the heart and reproductive organs.

If scans of imaging reveal a possible mass in the lungs or stomach the doctor will request biopsies. In the course of the procedure, doctors remove small amounts of fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma and indicate the most effective treatment plan.

There are several types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. The majority of doctors use an amalgamation of these techniques. Patients can also benefit by taking part in a clinical trial of new mesothelioma therapies. To learn more, patients should consult mesothelioma specialists who have experience treating the condition.
