Mesothelioma and Asbestos

Asbestos is a mineral that occurs naturally in the form of long, thin fibers. Workers who are exposed to asbestos regularly are at risk of developing mesothelioma or other lung diseases of different types.

It may take decades before symptoms begin to manifest after exposure to asbestos attorney. Different asbestos types may cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the lung's outer lining (pleura). It is the most common mesothelioma type, accounting for up 70% to 79% of diagnosed cases. The condition can cause chest pain, shortness of breathe and a feeling heavyness.

Exposure to asbestos, a family of minerals composed of microscopic fibers, typically causes this kind of cancer. Once inhaled, the fibers cling to the lungs and cause irritation that results in scarring and DNA mutations. The pleura surrounds the lungs and chest cavity and therefore, these irritations could affect both the lungs and a person's heart. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural melanoma are chest discomfort and shortness of breath. Some patients may also suffer from chest tightness and coughing, or breathing difficulties. Patients with this cancer have a history of disease that includes asbestos exposure at work. Manufacturing, construction, and shipbuilding are the most common occupations that put people at a high chance of developing pleural mesothelioma. People who have worked in the military may be at an especially high risk due to the frequent use of asbestos in Navy ships and army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system used for pleural adenocarcinoma. The stage a patient is in at the time of diagnosis can help determine the treatment plan they should follow. For instance, patients suffering from mesothelioma pleural stage three or four have a poorer prognosis than those in lower stages. Stage four mesothelioma is often spread to the liver, diaphragm and/or a person's heart. This makes it more difficult to treat and increases the risk of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural cancer, which forms in the lining of the lung, peritoneal cancer develops in the membrane that covers the abdominal cavity, which includes organs like the intestines and liver. As with pleural mesothelioma asbestos exposure is the primary cause of peritoneal mesothelioma. The disease is much less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

As with pleural asbestosis symptoms can take a long time to manifest. Patients typically experience 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 digestive issues, which could lead to incorrect diagnosis.

Generally speaking, doctors can detect mesothelioma by conducting a thorough health history and physical exam. Imaging tests such as X-rays or CT scans can be used to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer that aren't evident on X-rays.

These tests enable doctors to diagnose mesothelioma, determine the stage and suggest treatment options. The stage is determined by the kind of cell and if the cancer has spread.

The most significant mesothelioma risk factor is asbestos exposure. People who have worked in asbestos case, peruverse0.bravejournal.net post to a company blog,-related jobs, such as 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 areas they may be exposed to asbestos through relatives or other sources. Anyone who suspects that they may be at risk should consult an expert. If they have an history of exposure to asbestos, a mesothelioma specialist can assist them in finding out more about the risk.

Risk Factors

asbestos litigation exposure is the primary risk factor for mesothelioma which accounts for as much as 80 percent of all cases. Exposure to asbestos can happen through work, military service, or by living with someone who works with asbestos or was previously exposed to doing so. When exposed to asbestos, small particles can be inhaled into the abdomen and lungs. These irritate the linings and trigger cancerous cells to form in the mesothelium. Mesothelioma can take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and age. People in their 40s and 50s are more likely to develop mesothelioma than those who are younger or older. It takes mesothelioma between 20 and 60 years to show signs of cancer after the first exposure. It is important to remember that mesothelioma may develop in those who were exposed to asbestos but didn't deal with it directly. This is known as secondary or indirect asbestos claim exposure. It can be as dangerous as direct asbestos exposure.

Smoking increases the risk of mesothelioma, since it damages mesothelium. It also makes it more susceptible. In addition, mesothelioma may be worsened by certain diseases like asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. This is due to the fact that men are more likely to work with asbestos and experience a an extended period of exposure than women. Additionally, men are more likely to live with someone who worked with asbestos and carry asbestos fibers from their workplace on their clothes. Women are less likely to be in contact with asbestos, and they are less likely to carry asbestos on their clothes.

Diagnosis

It is difficult to identify mesothelioma since its symptoms are often similar to other conditions. Because of this, victims are sometimes misdiagnosed.

The first step in identifying 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 can also request a chest X-ray or CT scan to detect lumps or other abnormalities, and also to look for evidence of asbestos exposure in the past such as plaques in the pleura (thickened pleura with calcium deposits) and the formation of fluid between the lung and chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart and magnetic resonance imaging, also known as MRI, test, which makes use of radio waves and magnets to create precise images of the inside of the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. During a surgical biopsy, doctors remove a small piece of tissue from the pleura or peritoneum for further analysis. A pathologist then examines the tissue using a magnifying glass to determine if it is a cancerous cells.

The type of mesothelial cell involved, the malignant or benign nature of the cells and the location, type and stage of the cancer are used to categorize the disease. Certain mesothelioma types have a higher risk of spreading or metastasizing, so it's important to determine the type of mesothelioma so doctors can treat it prior to it becoming out-of-control.

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

Treatment

A diagnosis of mesothelioma can be a frightening prospect. It is important to keep in mind, however, that cancer can be treated, especially at its early stages. Many people with mesothelioma live for a long time with the disease, without spreading to other areas of their body.

Exposure to asbestos can cause mesothelioma in a number of ways. Asbestos fibers, which are too small to be able to see or feel by the naked eye can become airborne and cause irritation to the lining of the lungs (pleura). As time passes irritation can lead to formation of scar tissue which can cause changes in the cell structure that can eventually grow into tumors.

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

The symptoms of pleural mesothelioma are shortness of breath and chest pain, or the accumulation of fluid on the lungs (pleural effusion). In rare instances, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal a possible mass in the stomach or lungs the doctor will request biopsies. The procedure involves the removal of some of the liquid or tumor for tests in the laboratory. The results can confirm a mesothelioma diagnosis, and indicate the best treatment option.

There are many types of mesothelioma treatment, which include chemotherapy, surgery, and immunotherapy. Most doctors rely on an amalgamation of these techniques. Participating in clinical trials of new mesothelioma treatment may also be beneficial to patients. Patients can learn more by consulting a mesothelioma expert who has treated the disease.
