Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in thin, long fibres. Workers who are exposed asbestos on a regular basis risk developing mesothelioma and other types of lung diseases.

The symptoms of these diseases might not be evident for a long time after exposure to asbestos claim. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that affects the outer lung lining (pleura). It is the most common mesothelioma form and accounts for 70% to 79% of all diagnosed cases. People with this condition experience pain in the chest and shortness of breath and may experience an ache or heaviness in the chest.

This type of cancer typically caused through exposure to asbestos, which is a cluster of minerals composed of microscopic fibers. The fibers, when inhaled, cause irritation and DNA mutations. Pleura covers both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma is usually not symptomatic 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. Patients with this cancer have a history that includes asbestos exposure at work. The most prevalent jobs that put people at risk of developing pleural mesothelioma are manufacturing, construction and shipbuilding. People who have worked in the military could be at a higher risk due to the frequent asbestos usage in Navy vessels and bunkers for the army.

The TNM (tumors, lymph nodes, and metastases staging system) is the most commonly used staging system for the pleural adenocarcinoma. The stage that a patient is in at the moment of diagnosis will determine the treatment plan they will receive. Patients who have pleural mesothelioma which is in stage three or four will have a less favorable prognosis than those in a lower stage. Stage four mesothelioma is often spread to the diaphragm, liver or even the heart of a patient. This makes the cancer more difficult to treat, and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum - an elongated membrane that covers the abdominal cavity and organs such as the intestines and liver. Similar to pleural mesothelioma mesothelioma is caused by asbestos exposure. The disease is less common than pleural mesothelioma. There are just 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. The majority of patients are afflicted with abdominal pain as well as abdominal swelling. This kind of mesothelioma can cause nausea, weight loss and fever. A lot of these symptoms are similar to those experienced by gastrointestinal issues, which can result in confusion in diagnosis.

Doctors can detect mesothelioma by reviewing the medical history of the patient and performing a physical examination. They can also use imaging tests such as X-rays, CT scans and PET/CT scans to detect mesothelioma. These tests can reveal tumors and other signs of cancer that are not evident on X-rays.

These tests enable doctors to identify mesothelioma, and determine the stage. They can also recommend treatments. The stage is determined by the kind of cell and if the tumor has spread.

The most significant mesothelioma-related risk factor is exposure to asbestos. People who have been in occupations that involve asbestos, like plumbing or electrical work, manufacturing or construction, are at greater risk of developing the disease. Even if they aren't employed in these fields they may be exposed to asbestos through family members or other sources. Anyone who suspects that they may be at risk should talk to an expert. A mesothelioma specialist can help those with a history with asbestos (the full report) to learn more about their risk.

Risk Factors

Asbestos is the most significant risk factor for mesothelioma. It accounts for up to 80percent of cases. Exposure to asbestos can occur as a result of work, military service, or living with those who worked with asbestos. asbestos lawyer particles are inhaled by people who are exposed to it. These irritate the linings and can cause cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and the advancing age. The people in their 40s or 50s are at a higher risk of developing mesothelioma as compared to people who are younger or more. It takes mesothelioma between 20 and 60 years to manifest cancer symptoms after the first exposure. It is also important to note that mesothelioma may develop in people who were exposed to asbestos, but did not engage directly with it. This is referred to as secondary or indirect asbestos exposure, and is as dangerous as direct asbestos exposure.

Smoking increases the risk of getting mesothelioma because it damages the mesothelium and makes it more prone to asbestos. Mesothelioma can also be aggravated by certain diseases, such as asbestosis and pneumonia. It is also important to know that mesothelioma is more common in males than females. Men are more likely than women to have been exposed to asbestos compensation for a longer period of time and work with it. Additionally, men are more likely to live with someone who was exposed to asbestos legal and bring asbestos fibers that have escaped home on their clothes. Women are less likely to be exposed to asbestos and they are less likely to bring asbestos home on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma because its symptoms are frequently similar to other illnesses. Because of this, victims are sometimes wrongly diagnosed.

NYU Langone doctors will perform an examination of the body and document the patient's medical background including asbestos exposure. Doctors will also recommend 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 a magnetic resonance scan or MRI test, that uses radio waves and magnets 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. During a surgical biopsy, doctors remove a small amount of tissue from the pleura or peritoneum for further analysis. A pathologist can then examine the tissue with a magnifying glass to determine if it is a cancerous cell.

The type of mesothelial cell involved, the malignant or benign nature of those cells as well as the location and stage of the tumour, are used to classify the disease. Some types of mesothelioma have greater risk of metastasizing or spreading and it's crucial to determine the type of mesothelioma to ensure that the doctors can treat it before it becomes out-of-control.

Doctors may also conduct tests in the laboratory on a tumor to find specific genes, proteins, or other factors that help them understand the cancer's characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is important to keep in mind that cancer can be treated especially at its early stages. Many patients with mesothelioma live with the disease for a long time without expanding.

Asbestos exposure can trigger mesothelioma via a variety of mechanisms. Asbestos fibres, small enough to not be felt or observed by naked eyes are able to become airborne, irritating the lining of the lung (pleura). Over time, the irritation causes the formation of scar tissue which leads to changes in the cell structure which eventually lead to tumors.

The pleura surrounds the lungs and heart and also the abdomen. Mesothelium consists of cells that react to exposure to asbestos and cause it to enflame and form scar tissue. As time passes, these changes result in the growth of malignant mesothelioma tumors.

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

A doctor will request a biopsy if imaging scans show a potential mass in the lungs or stomach. During the procedure, doctors remove small amounts of the tumor or fluid for lab analysis. The results will confirm the diagnosis of mesothelioma and determine the best treatment plan.

There are a variety of treatment for mesothelioma, such as chemotherapy and surgery. The majority of doctors use the combination of these methods. Patients may also benefit from taking part in a clinical trial of new mesothelioma therapies. Patients can find out more by consulting a mesothelioma specialist who has treated the condition.
