Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that is made up of long, thin fibres. People who are exposed to asbestos may develop lung diseases such as mesothelioma.

It can take years before symptoms begin to manifest after asbestos exposure. Different asbestos types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung liner (pleura). It is the most common mesothelioma type and is responsible for 70 to 79% of all diagnosed cases. Patients suffering from this condition feel chest pain and breath shortness and may experience a sensation of heaviness in the chest.

This type of cancer typically caused by exposure to asbestos, which is a collection of minerals that are comprised of microscopic fibres. These fibers, when inhaled can cause irritation and DNA mutations. Pleura is the lining of both the chest cavity and the lungs, which means that irritations can also affect the heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma include chest pain and breath shortness. Patients may also experience chest tightness and coughing, or breathing difficulties. Patients with this type of cancer have a history of disease that includes asbestos exposure at work. 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 risk due to the frequent asbestos use in Navy vessels and bunkers used by the army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has when they are diagnosed will help their doctor determine the most appropriate treatment plan for them. For example, patients with mesothelioma that is pleural in stage three or four have a poorer prognosis than patients with lower stages. Mesothelioma in stage four can develop into the liver, heart, or diaphragm. This can make it more difficult to treat and increases the chance of complications for the patient.

Peritoneal Mesothelioma

Contrary to pleural cancer which is found in the lung's lining it develops in a membrane that covers the abdominal cavity, which includes organs like the intestines and liver. As with pleural mesothelioma asbestos exposure is the cause of peritoneal mesothelioma. The disease is much less prevalent than pleural mesothelioma, and around 300-500 cases being diagnosed each year.

As with pleural mesothelioma symptoms can take a long time to manifest. Patients usually experience abdominal pain, and may also have a lump in their abdomen. This mesothelioma type can also cause nausea, weight loss, and fever. Many of these symptoms are similar to those experienced by digestive problems, which can result in incorrect diagnosis.

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

These tests enable doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. Staging is determined based on the cell type and whether or the cancer has spread to other areas of the body.

Asbestos exposure is the biggest risk factor. People who have been in occupations that involve asbestos, such as plumbing or manufacturing, electrical work, or construction, are at increased risk of developing the disease. Even if a person isn't employed in one of these fields, he or she can still be exposed to asbestos case - right here on shop7.kokoo.kr, through family members and other sources. For this reason, anyone who suspects they may be at risk should speak to an expert. If they have an history of exposure to asbestos and mesothelioma is a concern, a specialist will help them find out more about their risk.

Risk Factors

Asbestos exposure is the primary mesothelioma risk factor, which accounts for 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 used to do the same. Asbestos particles are inhaled by people who are exposed to asbestos. They can cause irritation to the linings of the abdomen and can cause cancerous cells to grow in the mesothelium. Mesothelioma can take anywhere between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics, and age. People in their 40s or 50s are at a higher chance of developing mesothelioma to people who are younger or more. This is because mesothelioma usually takes 20 to 60 years after the initial time of exposure before symptoms of cancer begin to manifest. It is important to keep in mind, too, that mesothelioma can occur in people who have been exposed to asbestos without having directly worked with it. This is called indirect or secondary exposure to asbestos. It is just as harmful as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium and makes it more prone to asbestos. In addition, mesothelioma may be worsened by certain diseases like pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to have lived with someone who had been exposed to asbestos, and to have asbestos litigation fibers on their clothing. Women tend to be less exposed to asbestos and don't typically carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms are often similar to other conditions. This can lead to victims being misdiagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform an examination and write note of the medical history of the patient, including asbestos exposure. Doctors may also request a CT scan or chest X-ray to check 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 uses magnets and radio waves in order to produce a series of precise images of inside the body. Another method doctors use to diagnose mesothelioma is to perform the procedure of a surgical biopsy. During a surgery biopsy doctors will remove a small piece of tissue from pleura or the peritoneum to be tested further. A pathologist can then examine the tissue with a magnifying glass to determine whether it contains cancerous cell.

The mesothelial type involved as well as the benign or malignant nature of the cells, as well as the location, type and stage of the tumor, are used to classify the disease. Certain mesothelioma types have an increased risk of spreading or metastasizing, so it's important to establish a clear diagnosis to ensure that the doctors can treat it before it becomes out of control.

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

Treatment

A mesothelioma diagnose can be terrifying. However, it's important to keep in mind that the cancer is treatable, especially in its early stages. Many patients with mesothelioma endure the disease for a long time, without spreading.

Exposure to asbestos can cause mesothelioma by a variety of mechanisms. Asbestos fibers, which are tiny enough to be felt or seen with the naked eyes can be airborne, irritating the lung's lining (pleura). In time irritation leads to formation of scar tissue which can cause changes in the cell structure that eventually develop into tumors.

The pleura is a protective covering that surrounds the lungs, heart and abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They cause inflammation to the tissue and cause it to become scarred. In time, these changes can lead to the development of malignant mesothelioma cancers.

A shortness of breath, chest discomfort, or the accumulation of fluid on the lungs are all symptoms of pleural mesothelioma. In rare instances cancer may spread to the tissues that surround the reproductive organs as well as the heart.

If imaging scans show an area of concern in the lungs or stomach the doctor will request biopsies. The procedure involves the removal of a small amount of fluid or tumor to allow for lab tests. The results will confirm a mesothelioma diagnosis and determine the best treatment plan.

There are several types of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors use the combination of these treatments. Participating in clinical trials for mesothelioma treatments may be beneficial for patients. Patients can learn more by consulting a mesothelioma specialist who has treated the disease.
