10 Fundamentals On Mesothelioma And Asbestos You Didn't Learn At School > 자유게시판

Mesothelioma and Asbestos

Asbestos, a natural mineral, naturally occurs in the form of long, thin fibers. People who are regularly exposed to asbestos may develop lung diseases, such as mesothelioma.

It may take decades for symptoms to show up after asbestos exposure. Different brockton asbestos lawsuit types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that develops in the outer lung the lining (pleura). It is the most frequent mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. The condition can cause chest pain, shortness of breathe, and a feeling of heaviness.

Exposure to asbestos, a class of minerals composed of microscopic fibers, typically causes this type of cancer. Once inhaled, these fibers stick inside the lungs and cause irritation that leads to scarring and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural mesothelioma are chest pain and shortness of breath. Some patients may also suffer from chest tightness or coughing. They may also experience difficulty breathing. Patients with this cancer have a history of disease that includes asbestos exposure at work. Construction, manufacturing and shipbuilding are the most prevalent occupations which put people at risk danger of developing pleural melanoma. People who have worked in the military may be at risk due to the frequent asbestos attorneys usage in Navy vessels and army bunkers.

The TNM (tumors, lymph nodes, and metastases staging system) is the most popular staging system for the pleural adenocarcinoma. The stage the patient is in at the moment of diagnosis will determine the treatment plan they should receive. For example, patients with a pleural mesothelioma in stage three or four have a poorer prognosis than patients with a lower stage. Stage four mesothelioma may develop into the liver, heart, or diaphragm. This makes it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

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

Like pleural mesothelioma, symptoms can take a long time to manifest. The majority of patients experience abdominal pain and abdominal swelling. This type of mesothelioma may also cause nausea, weight loss, and fever. Many of these symptoms could be mistaken for gastrointestinal problems which can lead to a false diagnosis.

Typically, doctors can identify mesothelioma by conducting a thorough health history and physical examination. Imaging tests like X-rays and CT scans can be used to detect mesothelioma. These tests can reveal cancerous tumors or other signs of cancer that aren't visible on X-rays.

These tests enable doctors to diagnose mesothelioma, identify the stage and suggest treatment options. Staging is determined based on the type of cell and whether or the tumor has spread to other regions of the body.

Asbestos exposure is the biggest risk factor. People who have been exposed to asbestos in jobs, such as electrical or plumbing work, or in construction and manufacturing, are more likely to contract the disease. Even if a person is not employed in one of these areas they could still be exposed through family members or other sources. For this reason, anyone who suspects they may be at risk should talk to a doctor. A mesothelioma expert can help those with a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos exposure is a major mesothelioma risk factor, accounting for up to 80 percent of all cases. Exposure to asbestos can happen due to work, military service, or by living with someone who works with asbestos or used to do such. Asbestos particles can be inhaled by people who are exposed to asbestos. These particles can cause irritation to the linings of the lungs, causing cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or older. Mesothelioma can take between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is important to note, too, that mesothelioma can develop in people who have been exposed to asbestos, but without having directly worked with it. This is called secondary or indirect exposure to asbestos and it could be as hazardous as direct exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It can also make it more vulnerable. Mesothelioma can also be caused by certain illnesses such as asbestosis and pneumonia. It is also important to know that mesothelioma is more common in men than women. This is because men are more likely to work with asbestos and have a longer period of exposure than women. Men are also more likely to have lived with someone who had been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos on their clothing.

Diagnosis

It is difficult to recognize mesothelioma because its symptoms are often similar to other diseases. This can result in patients being wrongly diagnosed.

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

Other diagnostic tests include a magnetic resonance scan or MRI test, which uses magnets and radio waves to create a series detailed images of the insides of the body. Another way for doctors to detect mesothelioma is through an operation called a biopsy. During a surgery biopsy doctors will remove a small piece of tissue from pleura or the peritoneum, to be examined further. A pathologist is then able to look at the tissue under microscopes to determine if it has cancerous cells.

The type of mesothelial cell involved as well as the benign or malignant nature of the cells as well as the location the cancer, its type and the stage of the tumour, are used to classify the disease. Certain types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to establish a definitive diagnosis so doctors can treat the disease before it gets out of control.

Doctors can also perform tests in the laboratory on tumors to identify specific genes, proteins, or other factors which can help them describe cancer characteristics and plan treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis can be a frightening prospect. It is important to remember that cancer can be treated especially at its early stages. Many people with mesothelioma live for many years with the disease without it spreading to other parts of their body.

Exposure to asbestos can trigger mesothelioma via a variety of mechanisms. Asbestos fibers, too small to see or feel by the naked eye can be airborne and cause irritation to the lining of the lungs (pleura). In time, the irritation causes the formation of scar tissue, which can cause changes in the structure of cells that can eventually grow into tumors.

The pleura is a protective covering that surrounds the abdomen, heart, and lungs. Mesothelium is composed of cells that react to exposure to asbestos, causing it to inflame and form scar tissue. In time, these changes can result in the growth of malignant mesothelioma cancers.

Breathing problems, chest discomfort, or the accumulation of fluid on the lungs are all indications of pleural mesothelioma. In rare cases, the cancer can be spread to the tissues around the heart and reproductive organs.

If imaging scans reveal an area of concern in the stomach or lungs, a doctor will order biopsies. During the procedure doctors remove small amounts of fluid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma, and also determine the most effective treatment plan.

There are many types of treatment for mesothelioma, including chemotherapy and surgery. Most doctors rely on an amalgamation of these techniques. Patients may also benefit from participating in a clinical study of new mesothelioma therapies. To learn more about the trials, patients should speak with mesothelioma experts who have expertise in treating the condition.
