Mesothelioma and Asbestos

Asbestos, a mineral that naturally forms in the form of long, thin fibers. Workers who are regularly exposed to asbestos may develop lung diseases like mesothelioma.

It can take years for symptoms to show up after asbestos exposure. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer of the lung's outer lining, or the pleura. It is the most common mesothelioma form and accounts for 70% to 79% of diagnosed cases. The condition can cause chest pain, breath shortness and a feeling of weightiness.

Exposure to asbestos, a class of minerals comprised of microscopic fibers causes this kind of cancer. Once inhaled, these fibers cling to the lungs and cause irritation that leads to scarring and DNA mutations. The pleura covers 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.

Chest pain and shortness breath are the most common symptoms. Some patients may also feel tightness in their chest, coughing or difficulty breathing. Patients with this type of cancer typically have an history of exposure to asbestos in the workplace. The most frequent jobs that expose workers to the risk of developing pleural mesothelioma are manufacturing, construction, and shipbuilding. People who have served in the military may be at a higher risk due to the widespread asbestos usage in Navy ships and bunkers used by the army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used to treat pleural adenocarcinoma. The stage that a patient is in at the time of diagnosis can help determine the treatment plan they will receive. For instance, patients who have mesothelioma pleural stage three or four have a poorer prognosis than those with a lower stage. Mesothelioma in stage four is usually spread to the liver, diaphragm and/or a person's heart. This can make it more difficult to treat and increase the likelihood of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which is a lung-lining cancer, peritoneal mesothelioma forms in the peritoneum, an elongated membrane that covers the abdominal cavity and organs such as the intestines and liver. As with pleural mesothelioma asbestos claim exposure is the cause of peritoneal msothelioma. There are only 300-500 cases diagnosed annually this is less than pleural asbestosis.

As with pleural asbestosis, symptoms can take a long time to manifest. The majority of patients are afflicted with abdominal pain as well as a mass in the abdomen. Symptoms of this type of mesothelioma may also include nausea or weight loss, as well as fever. Many of these symptoms could be mistaken for gastrointestinal problems, leading to a mistaken diagnosis.

Typically, doctors can identify mesothelioma after a thorough health history and physical exam. Imaging tests such as X-rays or CT scans are a way to identify mesothelioma. These tests can detect tumors as well as other signs of cancer which aren't visible on X-rays.

These test results allow doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage is determined by the kind of cell and if the tumor has spread.

The most important risk factor for mesothelioma is exposure to asbestos. People who have been in occupations which require asbestos, like plumbing or manufacturing, electrical work, or construction, are at increased risk of developing the disease. Even if a person is not employed in any of these areas however, they may be exposed to asbestos through family members or other sources. This is why anyone who is concerned that they might be at risk should talk to an expert. A mesothelioma specialist can assist those who have had a previous history of asbestos to find out more about their risk.

Risk Factors

Asbestos is the primary mesothelioma-related risk factor. It accounts for as much as 80percent of cases. Exposure to asbestos may occur as a result of military service, work or living with those who worked with asbestos lawyer. Asbestos particles are inhaled by people who are exposed to it. These particles can cause irritation to the linings, causing cancerous cells to develop in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more at risk of developing mesothelioma as compared to people who are younger or more. It takes mesothelioma 20-60 years to manifest cancer symptoms after the first exposure. It is important to remember that mesothelioma can occur in those who have been exposed to asbestos without having directly worked with it. This is known as indirect or secondary exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the chance of mesothelioma developing, as it damages the mesothelium. It can also make it more vulnerable. Mesothelioma can also be aggravated by certain illnesses such as asbestosis and pneumonia. It is also important to remember that mesothelioma is more prevalent in men than women. This is due to men being 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 worked with asbestos, and to have asbestos fibers on their clothing. Women tend to have less exposure to asbestos case (visit the next website page) and don't typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is difficult to identify because the symptoms are often similar to other conditions. Due to this, patients are often mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform an examination and write note of the medical history of the patient which includes asbestos exposure. Doctors will also order an CT scan or chest X-ray to check for lumps, abnormalities and evidence of asbestos exposure. These include plaques in the pleura, thickened pleura and calcium deposits.

Other diagnostic tests include a magnetic resonance image, or MRI test, which uses radio waves and magnets in order to create a series of detailed images of the insides of the body. Another way doctors can diagnose mesothelioma is through an operation called a biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the pleura or peritoneum for further analysis. A pathologist can then examine the tissue using a magnifying lens to determine whether it contains cancerous cell.

Mesothelioma can be classified based on the mesothelial type involved, whether those cells are benign or malignant and the location of the tumor, the type, and the stage of the cancer. Certain mesothelioma types have a higher chance of metastasizing or spreading and it's crucial to determine the type of mesothelioma to ensure that the doctors can treat it prior to it becoming out of control.

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

Treatment

A mesothelioma diagnose can be frightening. However, it is important to remember that the disease can be treated, particularly in its early stages. Many people with mesothelioma live for a long time with the disease without it spreading to other organs of their body.

Exposure to asbestos law can trigger mesothelioma via many mechanisms. Asbestos fibers that are tiny enough to be felt or seen with the naked eyes can be airborne, causing irritation to the lung's lining (pleura). In time the irritation causes the formation of scar tissue that eventually result in tumors.

The pleura is the area that surrounds the lungs and heart and the abdomen. Mesothelium consists of cells that react to asbestos, causing it to inflame and develop scar tissue. These changes can eventually lead to malignant mesothelioma tumours.

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

A doctor will order a biopsy if imaging scans show a potential lung tumor or stomach. During the procedure doctors remove small amounts of liquid or tumor for tests in the laboratory. The results can confirm the diagnosis of mesothelioma and indicate the best treatment plan.

There are a variety of treatment for mesothelioma, such as chemotherapy and surgery. The majority of doctors employ the combination of these treatments. Participating in clinical trials of mesothelioma treatments that are new could be beneficial to patients. To learn more about the trials, patients should consult mesothelioma specialists who have experience treating the condition.
