Guide To Mesothelioma And Asbestos: The Intermediate Guide Towards Mesothelioma And Asbestos

Mesothelioma and Asbestos

Asbestos is a natural mineral that is made up of long, thin fibres. People who are exposed to asbestos are at risk of developing lung diseases such as mesothelioma.

It could take a long time for symptoms to show up after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

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

Exposure to asbestos, a class of minerals comprised of microscopic fibers causes this type of cancer. These fibers, when inhaled can cause irritation and DNA mutations. Pleura covers both the chest cavity and the lungs, and so irritations can also affect the heart. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

Chest pain and shortness breath are the most common symptoms. Patients may also experience chest tightness or coughing. They may also experience difficulty breathing. Patients with this type of cancer have a past that includes asbestos attorney exposure at work. Construction, manufacturing, and shipbuilding are the most common occupations that put people at a high risk of developing pleural mesothelioma. People who have worked in the military are at an especially high risk due to the frequent asbestos use in Navy vessels and army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most popular staging system used to treat the pleural adenocarcinoma. The stage a patient is in upon diagnosis will assist their doctor in determining the best treatment plan for them. Patients who have pleural mesothelioma which 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 liver, diaphragm and/or a person's heart. This makes it more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

As opposed to pleural mesothelioma that develops in the lung lining, peritoneal mesothelioma is found in the peritoneum -- an elongated membrane that covers the abdominal cavity and organs such as the liver and intestines. Similar to pleural mesothelioma, asbestos exposure is the primary cause of peritoneal mesothelioma. Only 300-500 cases are diagnosed each year which is lower than the pleural asbestosis.

As with pleural asbestosis symptoms can take years to show. Patients typically have abdominal pain, and may also have a lump in their abdomen. This type of mesothelioma may cause nausea, weight loss, and fever. Many of these symptoms are similar to those of gastrointestinal issues, which can result in incorrect diagnosis.

The doctors can detect mesothelioma through reviewing the medical history of the patient and performing a physical exam. They may also employ imaging tests like Xrays, CT scans and PET/CT scans to help find mesothelioma. These tests can show tumors and other indications of cancer that aren't apparent on an X-ray.

These test results enable doctors to diagnose mesothelioma and establish the stage. They also offer treatment options. The staging is determined by the type of cell and whether or not the cancer has spread to other areas of the body.

The most important mesothelioma-related risk factor is exposure to asbestos law. People who have worked in asbestos-related occupations, like electrical or plumbing work, or in construction and manufacturing, are more likely to develop the disease. However, even if people do not work in these fields they could be exposed to asbestos through relatives or other sources. This is why anyone who is concerned that they might be at risk should speak to an expert. If they have an history of exposure to asbestos or mesothelioma, a specialist can assist them in learning more about the risk.

Risk Factors

Asbestos exposure is the primary risk factor for mesothelioma, which accounts for as much as 80 percent of cases. Exposure to asbestos can occur through work, military service, or by living with someone who is exposed to asbestos or has previously done so. Asbestos particles can be inhaled by people who are exposed to it. These particles irritate the linings of the abdomen, which causes cancerous cells to form in the mesothelium. Following exposure to asbestos settlement mesothelioma can be diagnosed between 15 and 60 years old.

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 more senior. This is because mesothelioma typically takes 20 to 60 years after the initial time of exposure before cancer symptoms appear. It is important to remember that mesothelioma may develop in those who were exposed to asbestos, but did not deal with it directly. This is known as indirect or secondary exposure to asbestos. It could be as hazardous as direct exposure.

Smoking increases a person's chances of developing mesothelioma since it damages the mesothelium and makes it more vulnerable to asbestos. Furthermore, mesothelioma is caused by certain illnesses, such as pneumonia and asbestosis. It is also important to remember that mesothelioma occurs more frequently in men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and work with asbestos for longer periods of time. Men are also more likely to have lived with someone who has been exposed to asbestos, and to carry asbestos fibers on their clothing. Women tend to have less contact with asbestos and rarely carry asbestos home on their clothing.

Diagnosis

Mesothelioma is difficult to identify because the symptoms are often similar to other conditions. This can result in patients being incorrectly diagnosed.

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

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels and magnetic resonance imaging, also known as MRI test that uses magnets and radio waves to create detailed images of the interior of the body. A surgical biopsy is yet another method for doctors to identify mesothelioma. When a biopsy is performed doctors take a tiny piece of tissue from pleura or the peritoneum, to be examined further. A pathologist can examine the tissue with microscopes to determine whether it is contaminated with cancerous cells.

The type of mesothelial cells involved and the benign or malignant nature of those cells, as well as the location, type and stage of the tumor, are used to classify the disease. Some types of mesothelioma are more likely to grow or spread and spread, therefore it is essential to establish a definitive diagnosis to ensure that doctors are able to treat the disease before it becomes out of control.

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

Treatment

A diagnosis of mesothelioma may be frightening. It is important to remember that cancer can be treated particularly in its initial stages. Many people with mesothelioma can endure the disease for a long time, without spreading.

Exposure to asbestos may cause mesothelioma through a variety of ways. Asbestos fibres, too small to be felt or seen through the naked eye, can become airborne, irritating the lung's lining (pleura). Over time irritation can lead to formation of scar tissue, which can cause changes in the cell structure which eventually lead to tumors.

The Pleura is a covering that surrounds the lungs, heart and abdomen. Mesothelium consists of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. Overtime, these changes result in the growth of malignant mesothelioma tumors.

The symptoms of pleural mesothelioma are breathing problems and chest pain as well as a buildup of fluid on the lungs (pleural effusion). In rare instances cancer can spread to the tissues around the reproductive organs as well as the heart.

If imaging scans reveal an underlying mass in the lungs or stomach the doctor will request biopsies. The procedure involves the removal of a small amount of fluid or tumor for tests in the laboratory. The results will confirm a mesothelioma diagnosis and provide the best treatment option.

There are a variety of treatment for mesothelioma, such as chemotherapy and surgery. Most doctors rely on a combination of these methods. Patients can also benefit by participating in a clinical study of new mesothelioma treatment. To learn more about the trials, patients should speak to mesothelioma experts who have had experience treating the disease.
