Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that comes in long, thin fibres. Workers who are exposed to asbestos claim regularly are at risk of developing mesothelioma or other lung diseases of different types.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung the lining (pleura). It is the most common mesothelioma form and accounts for 70% to 79% of diagnosed cases. Patients with this disease suffer from chest pain and breath shortness and may experience a sensation of heaviness in the chest.

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

Shortness of breath and chest pain are the most frequent symptoms. Some patients also experience difficulty breathing or chest tightness. Patients with this type of cancer have a past that includes asbestos legal exposure at work. The most prevalent jobs that expose people to the risk of developing pleural mesothelioma are construction, manufacturing and shipbuilding. Individuals who have been in the military could be at risk due to the frequent asbestos use in Navy vessels and army bunkers.

The most commonly used 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 when they are diagnosed will assist their doctor in determining the most effective treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable prognosis than those who are in a less advanced stage. Mesothelioma in stage four is usually spread to the diaphragm, liver or even a person's heart. This can make it more difficult to treat and increase the likelihood of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lining of the lung it develops in a membrane that covers the abdominal cavity, including organs such as the intestines and liver. Similar to pleural mesothelioma, exposure to asbestos is the cause of peritoneal mesothelioma. The disease is less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, the symptoms can take a long time to manifest. Patients usually suffer from abdominal pain and may have a mass in their abdomen. The symptoms of this kind of mesothelioma can also include nausea or weight loss, as well as fever. Many of these symptoms are similar to those of digestive problems, which can result in incorrect diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and conducting a physical exam. Imaging tests such as X-rays or CT scans are a way to detect mesothelioma. These tests can reveal tumors and other signs of cancer that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma, determine the stage and suggest treatment options. Staging is determined based on the type of cell and whether or the cancer has spread to other regions of the body.

Asbestos exposure is the most important risk factor. People who have been in occupations that require asbestos, such as plumbing manufacturing, electrical work, or construction, are at increased risk of developing the disease. However, even if individuals do not work in these areas they could be exposed to asbestos through family members or through other sources. Anyone who believes they are at risk should consult an expert. If they have a history of asbestos settlement exposure and mesothelioma is a concern, a specialist will help them find out more about the risk.

Risk Factors

Asbestos is the primary risk factor in mesothelioma. It accounts for up to 80percent of cases. Exposure to asbestos can occur as a result of military service, work or living with people who have worked with asbestos. When exposed to asbestos, the particles can be breathed into the abdomen and lungs. These particles can cause irritation to the linings and can cause cancerous cells to grow in the mesothelium. Mesothelioma may take 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 be diagnosed with mesothelioma compared to those who are younger or older. It takes mesothelioma 20-60 years before it manifests cancer symptoms after the first exposure. It is important to note that mesothelioma could develop in those who have been exposed to asbestos without having directly worked with it. This is known as secondary or indirect asbestos [the original source] exposure, and is as dangerous as direct asbestos exposure.

Smoking increases a person's chances of developing mesothelioma due to the fact that it damages the mesothelium and makes it more vulnerable to asbestos. Furthermore, mesothelioma is caused by certain illnesses, such as asbestosis and pneumonia. Men are more likely to develop mesothelioma compared to women. This is due to men being more likely to be exposed to asbestos claim and endure a an extended period of exposure than women. Men are also more likely to live with someone who had asbestos exposure and bring stray asbestos fibers home on their clothing. Women are less likely to come exposed to asbestos, and they don't usually bring asbestos home on their clothes.

Diagnosis

It is difficult to recognize mesothelioma since its symptoms are frequently similar to other illnesses. This can result in patients being wrongly diagnosed.

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

Other diagnostic tests include a magnetic resonance image, or MRI test, that uses radio waves and magnets in order to produce a series of precise images of the insides of the body. Another way for doctors to detect mesothelioma is by performing the procedure of a surgical biopsy. When a biopsy is performed doctors take a tiny part of tissue from the pleura or the peritoneum, to be examined further. A pathologist is then able to look at the tissue under microscopes to determine whether it is contaminated with cancerous cells.

The mesothelial type involved and the benign or malignant nature of these cells and the location and stage of the tumour, are used to categorize the disease. Some types of mesothelioma have a higher chance of metastasizing or spreading therefore it is essential to determine the type of mesothelioma so doctors can treat it before it becomes out of control.

Doctors may also conduct tests in the lab on tumors to determine specific genes, proteins or other elements that can help them describe cancer characteristics and plan treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. It is important to remember, however, that cancer can be treated particularly in its early stages. Many mesothelioma patients live for a long time with the disease without it spreading to other areas of their body.

asbestos case exposure can trigger mesothelioma via various mechanisms. Asbestos fibers that are too small to be felt or observed by naked eyes can be airborne, irritating the lung's lining (pleura). In time irritation leads to formation of scar tissue, which causes changes in the structure of cells that eventually develop into tumors.

The pleura covers the lungs and heart and the abdomen. Mesothelium is composed of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. These changes eventually lead to malignant mesothelioma tumours.

Shortness of breath, chest pain or fluid accumulation on the lungs are all indications of the pleural msothelioma. In rare instances, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal an area of concern in the stomach or lungs, a doctor will order biopsies. In the course of the procedure, doctors remove a small amount of liquid or tumor for laboratory testing. The results will confirm the diagnosis of mesothelioma and indicate the best treatment plan.

There are a variety of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize a combination of these treatments. Participating in clinical trials for mesothelioma treatments may be beneficial to patients. Patients can find out more by consulting a mesothelioma expert who has treated the condition.
