Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is found in long, thin fibres. People who are exposed to asbestos risk developing lung diseases such as mesothelioma.

It can take years before symptoms begin to manifest after asbestos (visit this site right here) exposure. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma occurs in the lung's outer lining or the pleura. It is the most prevalent mesothelioma form and is responsible for 70 to 79% of all diagnosed cases. This condition causes chest discomfort, shortness of breath, and a feeling of heavyness.

This kind of cancer is usually caused by exposure to asbestos, which is a cluster of minerals comprised of microscopic fibres. When inhaled, these fibers cause irritation and DNA mutations. The pleura covers the lungs and chest cavity This means that these irritations can affect both the lungs and the heart of a person. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

The most commonly reported symptoms of pleural mesothelioma include chest discomfort and shortness of breath. Patients may also suffer from chest tightness and coughing, or breathing difficulties. Patients with this type of cancer typically have a history of exposure to asbestos in the workplace. The most common jobs that expose workers to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. Individuals who have been in the military may be at a higher risk due to the frequent asbestos usage in Navy vessels and bunkers for the army.

The most common staging system for pleural mysothelioma has been the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient is in at diagnosis will aid their doctor in determining the best treatment plan for them. Patients with pleural mesothelioma that is in stage three or four will have a less favorable prognosis than those who are in a less advanced stage. Stage four mesothelioma is often spread to the diaphragm, liver or even a person's heart. This can make it more difficult to treat and raises the likelihood of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural cancer, which is found in the lung's lining the peritoneal cancer is a result of a membrane that surrounds the abdominal cavity, which includes organs such as the intestines and the liver. Like pleural mesothelioma, peritoneal mesothelioma can be caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma, and only about 300-500 cases diagnosed each year.

As with pleural asbestosis, symptoms can take a long time to manifest. The majority of patients are afflicted with abdominal pain as well as abdominal swelling. The symptoms of this type of mesothelioma may also include nausea, weight loss and fever. A lot of these symptoms can be mistaken for gastrointestinal problems, leading to a mistaken 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 help find mesothelioma. These tests can reveal tumors and other cancer signs that aren't evident on X-rays.

These test results 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.

Asbestos exposure is the biggest risk factor. People who have worked in asbestos-related occupations, like electrical or plumbing work or in manufacturing and construction, are more likely to develop the disease. However, even if individuals do not work in these fields they could be exposed to asbestos claim through family members or other sources. Anyone who believes they are at risk should consult a doctor. A mesothelioma specialist can assist those who have a previous history of asbestos to find out more about their 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 lawsuit can happen as a result of work, military service, or living with people who have worked with asbestos. When exposed to asbestos, the particles can be breathed into the lungs and abdomen. They can cause irritation to the linings of the abdomen and cause cancerous cells to develop in the mesothelium. After asbestos exposure mesothelioma is likely to be diagnosed between 15 and 60 year.

Other risk factors include smoking, genetics and the advancing 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 to manifest cancer symptoms after the first exposure. It is important to remember, too, that mesothelioma can develop in people who have been exposed to asbestos, but without having directly worked with it. This is referred to as indirect or secondary exposure to asbestos. It can be just as dangerous as direct exposure.

Smoking can increase the likelihood of developing mesothelioma since it damages the mesothelium, which makes it more prone to asbestos. Mesothelioma is also aggravated by certain illnesses such as asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in men than women. Men are more likely than women to have been exposed to asbestos litigation for a longer time and work with it. Men are also more likely to have lived with someone who been exposed to asbestos, and to carry asbestos fibers on their clothing. Women are less likely to come 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 often similar to other conditions. Due to this, patients are often mistakenly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient, including asbestos exposure. Doctors may also request an 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, which makes use of radio waves and magnets in order to create a series of detailed images of inside the body. Another method doctors use to diagnose mesothelioma is by performing a surgical biopsy. During a surgery biopsy doctors take a tiny part of tissue from the pleura or the peritoneum, to be examined further. A pathologist can then examine the tissue with a magnifying lens to determine if it contains cancerous cell.

Mesothelioma is classified based on the type of mesothelial cells involved, whether these cells are malignant or benign and also the location, type, and stage of the cancer. Some types of mesothelioma have a higher chance of metastasizing or spreading therefore it is essential to establish a clear diagnosis so doctors can treat it before it gets out-of-control.

Doctors may also conduct tests in the laboratory on a tumor to identify specific genes, proteins or other elements which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma can be an incredibly frightening prospect. It is important to keep in mind that cancer can be treated particularly in its initial stages. Many patients with mesothelioma survive for many years with the disease, without spreading to other parts of their body.

Asbestos exposure can cause mesothelioma by various mechanisms. Asbestos fibres, small enough to not be felt or viewed with the naked eyes can be airborne, causing irritation to the lining of the lung (pleura). As time passes irritation can lead to formation of scar tissue which leads to changes in the cell structure that can eventually grow into tumors.

The pleura surrounds the lungs and heart and the abdomen. Mesothelium is composed of cells that react to exposure to asbestos litigation, causing it to inflame and form scar tissue. These changes can eventually result in malignant mesothelioma tumors.

Shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all symptoms of pleural mesothelioma. In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.

A doctor may request biopsy if scans reveal a possible mass in the lungs or stomach. During the procedure, doctors will remove tiny amounts of fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma and determine the most effective treatment plan.

There are many types of mesothelioma treatments, including chemotherapy, surgery and immunotherapy. The majority of doctors use the combination of these methods. Enrolling in clinical trials of new mesothelioma treatment may also be beneficial for patients. To learn more, patients should speak with mesothelioma specialists who have had experience treating the disease.
