Mesothelioma And Asbestos: A Simple Definition > 자유게시판

Mesothelioma and Asbestos

asbestos legal; over at this website,, a mineral that occurs naturally in the form of long, thin fibers. Workers who are regularly exposed to asbestos may develop lung diseases, such as mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, also known as pleura. It is the most prevalent mesothelioma type, accounting for up 70% to 79% of all diagnosed cases. Patients with this disease suffer from chest pain and breath shortness and may experience an ache or heaviness in the chest.

Exposure to asbestos, a family of minerals comprised of microscopic fibers causes this type of cancer. These fibers, when inhaled, cause irritation and DNA mutations. The pleura is the area that surrounds the lungs and chest cavity, so these irritations can affect both the lungs and a person's heart. Mesothelioma is usually not symptomatic until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Patients may have coughing problems, trouble breathing or chest tightness. People who suffer from this cancer usually have a history of exposure to asbestos in the workplace. The most frequent jobs that put people at risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who have served in the military could be at risk due to the widespread use of asbestos in Navy ships and bunkers for the army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most popular staging system for the pleural adenocarcinoma. The stage a patient has at diagnosis will aid their doctor in determining the most effective treatment plan for them. For instance, patients suffering from a pleural mesothelioma in stage three or four have a worse prognosis than those with a lower stage. Mesothelioma in stage four can be spread to the heart, liver or diaphragm. This can make the cancer more difficult to treat, and increase the chances of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum -- a membrane that lines the abdominal cavity as well as organs such as the intestines and liver. Similar to pleural mesothelioma, asbestos exposure is the reason for peritoneal msothelioma. Only 300-500 cases are diagnosed annually, which is less than pleural asbestosis.

As with pleural asbestosis symptoms can take several years to manifest. Typically, patients are afflicted with abdominal pain as well as an abdominal mass. Symptoms of this type of mesothelioma can also include nausea as well as weight loss and fever. Many of these symptoms are similar to those experienced by digestive issues, which could cause misdiagnosis.

The doctors can detect mesothelioma through reviewing the medical history of the patient and conducting a physical exam. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can detect tumors as well as other signs of cancer that aren't evident on X-rays.

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

Asbestos exposure is the most important risk factor. People who have worked in asbestos-related jobs, such as electrical or plumbing work, or in construction, manufacturing and manufacturing are more likely to contract the disease. However, even if people do not work in these fields they could be exposed to asbestos through family members or other sources. Anyone who thinks they may be at risk should speak with an expert. A mesothelioma expert can help those with a history with asbestos to learn more about their risk.

Risk Factors

Asbestos is the main risk factor in mesothelioma. It is responsible for as much as 80percent of cases. Exposure to asbestos can happen due to military service, work or living with those who worked with asbestos. When exposed to asbestos compensation, particles can be inhaled into the lungs and abdomen. These particles irritate the linings of the abdomen, which causes cancerous cells to develop in the mesothelium. After asbestos exposure, mesothelioma may occur between 15 and 60 year.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely to get mesothelioma than people younger or more senior. It takes mesothelioma 20-60 years to show signs of cancer after the first exposure. It is also important to know that mesothelioma may develop in people who have been exposed to asbestos compensation but did not work with it directly. This is called indirect or secondary exposure to asbestos. It is just as harmful as direct exposure.

Smoking increases a person's chances of getting mesothelioma because it damages the mesothelium and makes it more prone to asbestos law. Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is because men are more likely to work with asbestos and have an extended period of exposure than women. Also, men are more likely to live with someone who was exposed to asbestos and bring asbestos fibers from their workplace on their clothing. Women tend to be less in contact with asbestos, and they are less likely to bring asbestos home on their clothes.

Diagnosis

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

The first step to diagnose mesothelioma is for NYU Langone doctors to perform an examination and write notes on the medical history of a patient which includes asbestos claim exposure. Doctors can also request an X-ray of the chest or CT scan to look for lumps and other abnormalities and also to look for evidence of past asbestos exposure like plaques in the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include a magnetic resonance scan or MRI test, which makes use of magnets and radio waves to create a series of detailed images of the inside of the body. A surgical biopsy is a different method doctors use to diagnose mesothelioma. In a surgical biopsy doctors will remove a small piece of tissue from the pleura or the peritoneum, to be examined further. A pathologist can then examine the tissue with microscopes to determine whether it has cancerous cells.

Mesothelioma is classified based on the mesothelial type involved, whether those cells are malignant or benign and the location of the tumor, the type, and the stage of the tumor. Some types of mesothelioma have greater risk of metastasizing or spreading therefore it is essential to establish a clear diagnosis so that doctors can treat it before it becomes out of control.

Doctors may also conduct tests in the lab on a tumor to identify specific genes, proteins and other factors that help them understand the characteristics of cancer and plan treatment. These results are referred to as staging.

Treatment

A mesothelioma diagnose can be terrifying. It is important to keep in mind, however, that cancer can be treated especially at its early stages. A lot of people suffering from mesothelioma live with the disease for many years without it expanding.

Exposure to asbestos can trigger mesothelioma in many ways. Asbestos fibers, which are tiny enough to be felt or seen by naked eyes can be airborne, causing irritation to the lining of the lung (pleura). As time passes irritation leads to formation of scar tissue which causes changes in the structure of cells that can eventually grow into tumors.

The pleura covers the lungs and heart and also 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 cause mesothelioma cancers.

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

If imaging scans reveal an underlying mass in the lungs or stomach the doctor will request a biopsies. During the procedure doctors remove a small amount of fluid or tumor to allow for tests in the laboratory. The results will confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are several types of mesothelioma treatment, including chemotherapy, surgery and immunotherapy. The majority of doctors employ combinations of these treatments. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatments. Patients can learn more about the trials by consulting a mesothelioma specialist who has treated the disease.
