Mesothelioma and Asbestos

asbestos (Gstd official blog) is a naturally occurring mineral that is made up of long, thin fibres. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma or other types of lung diseases.

The symptoms of these diseases may not show up for decades after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

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

This type of cancer usually caused by exposure to asbestos, which is a cluster of minerals composed of microscopic fibers. These fibers, when inhaled, cause irritation and DNA mutations. The pleura covers the chest cavity and lungs, so these irritations can affect both the lungs as well as a person's heart. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Some patients have coughing problems, trouble breathing, or chest tightness. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. The most frequent jobs that expose people to the risk of pleural mesothelioma include manufacturing, construction and shipbuilding. Individuals who have been in the military could be at an especially high risk due to the frequent asbestos usage in Navy vessels and army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system for the pleural adenocarcinoma. The stage a patient has when they are diagnosed will aid their doctor in determining the most appropriate treatment plan for them. For instance, patients who have mesothelioma pleural stage three or four have a poorer prognosis than patients with lower stages. Stage four mesothelioma can develop into the liver, heart, or diaphragm. This makes the cancer more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that develops in the lung lining, peritoneal mesothelioma develops in the peritoneum, it is a membrane that lines the abdominal cavity and organs such as the intestines and liver. Like pleural mesothelioma, peritoneal mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Typically, patients suffer from abdominal pain and an abdominal mass. The symptoms of this type of mesothelioma can also include nausea, weight loss and fever. Many of these symptoms are similar to those of gastrointestinal issues, which can lead to incorrect diagnosis.

Generally speaking, doctors can detect mesothelioma through a thorough health history and physical examination. Imaging tests like X-rays and CT scans are a way to identify mesothelioma. These tests can reveal tumors and other signs of cancer that are not evident on X-rays.

These tests enable doctors to diagnose mesothelioma, determine the stage of the disease and suggest treatment options. The stage is determined by the type of cell and whether the cancer has spread.

The most important risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos-containing jobs, such as electrical or plumbing work or in construction and manufacturing are more likely to develop the disease. Even if they aren't employed in these fields, they can still be exposed to asbestos through relatives or other sources. Anyone who believes they're at risk should consult a doctor. A mesothelioma expert can help those who have a history with asbestos to learn more about their risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma, accounting for up to 80 percent 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 legal particles can be breathed in by people who are exposed to asbestos. These irritate the linings and can cause cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos attorney.

Other risk factors include smoking, genetics, and age. People in their 40s or 50s are at a higher chance of developing mesothelioma to those who are younger or older. It takes mesothelioma between 20 and 60 years to show signs of cancer after the first exposure. It is important to remember that mesothelioma can occur 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 just as harmful as direct asbestos exposure.

Smoking can increase the likelihood of getting mesothelioma because it damages the mesothelium and makes it more susceptible to asbestos. In addition, mesothelioma may be caused by certain illnesses, such as pneumonia and asbestosis. It is also important to know that mesothelioma occurs more frequently for men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with asbestos for longer periods of time. 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 exposed to asbestos, and don't typically bring asbestos home on their clothes.

Diagnosis

Mesothelioma is a difficult cancer to diagnose because the symptoms are often similar to other conditions. This is why patients are sometimes misdiagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors will also order a CT scan or chest X-ray to look for lumps, abnormalities and evidence of asbestos exposure. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include an echocardiogram which examines the blood vessels and the heart as well as a magnetic resonance imaging, also known as MRI test, which makes use of magnets and radio waves to create detailed images of the inside of the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. During a surgery biopsy doctors take a tiny piece of tissue from pleura or the peritoneum to be further examined. A pathologist then examines the tissue under an magnifying glass to determine whether it contains cancerous cell.

Mesothelioma is classified according to the type of mesothelial cells involved, whether these cells are benign or malignant and also the location of the tumor, the type, and the stage of the cancer. Some types of mesothelioma are more likely to develop metastasis or spread which is why it is crucial to establish a definitive diagnosis so doctors can treat the disease before it goes out of control.

Doctors may also conduct tests in the laboratory on a tumor to find particular proteins, genes and other factors that help them understand the characteristics of the cancer and determine a treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be frightening. However, it is important to remember that the disease can be treated, particularly in its earlier stages. Many patients with mesothelioma survive for years without the disease spreading to other organs of their body.

Exposure to asbestos can trigger mesothelioma in a number of ways. asbestos attorney fibers, which are too small to see or feel through the naked eye, can become airborne and cause irritation to the lining of the lungs (pleura). As time passes irritation can lead to formation of scar tissue which can cause changes in the structure of cells which eventually lead to tumors.

The pleura is a protective covering that covers the lungs, heart and abdomen. Mesothelium is made up of cells that react when exposed to asbestos. They cause inflammation to the tissue and cause it to scar. As time passes, these changes result in the growth of malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathlessness and chest pain as well as the accumulation of fluid in the lung (pleural effusion). In rare instances, the cancer can be spread to the tissues around the heart and reproductive organs.

If imaging scans reveal an underlying mass in the stomach or lungs, a doctor will order biopsies. During the procedure doctors remove some of the liquid or tumor for lab tests. The results will confirm a mesothelioma diagnosis and provide the most effective treatment plan.

There are many types of mesothelioma treatment options, which include chemotherapy, surgery, and immunotherapy. The majority of doctors use a combination of these methods. Patients may also benefit from participating in a clinical study of new mesothelioma treatments. Patients can find out more by speaking with a mesothelioma doctor who has treated the disease.
