Mesothelioma and Asbestos

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

The symptoms of these diseases might not show up for decades after exposure to asbestos. Different asbestos law types can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a type of cancer that affects the lung's outer liner (pleura). It is the most frequent mesothelioma type, accounting for up between 70 and 79% of diagnosed cases. Patients with this disease suffer from chest pain and shortness of breath and may also feel the sensation of weight in the chest.

This kind of cancer is usually caused by exposure to asbestos which is a collection of minerals that are comprised of microscopic fibres. Once inhaled, the fibers are absorbed into the lungs and cause irritation that results in scarring and DNA mutations. The pleura covers the chest cavity and lungs This means that these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms usually don't appear until 30 to 50 years after exposure.

The most common symptoms of pleural mesothelioma include chest pain and breath shortness. Some patients also experience difficulty breathing or chest tightness. People who suffer from this cancer usually have previous 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 may be at an especially high risk due to the frequent use of asbestos in Navy ships and bunkers used by the army.

The most popular staging system for pleural mesothelioma is the TNM (tumor lymph nodes, lymph nodes, and metastases) staging system. The stage a patient is in at the time of diagnosis will help determine the treatment plan they will receive. Patients who have pleural mesothelioma which is in stage three or four will have a less favorable outlook than those who are in a less advanced stage. Mesothelioma in stage four is usually spread to the liver, diaphragm or even a person's heart. This can make the cancer more difficult to treat and increase the risk of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural cancer, which is found in the lining of the lung, peritoneal cancer develops in the membrane that covers the abdominal cavity, including organs like the liver and intestines. Similar to pleural mesothelioma, asbestos exposure is the primary cause of peritoneal mesothelioma. It is estimated that only 300-500 cases are diagnosed each year this is less than pleural asbestosis.

As with pleural mesothelioma symptoms may take years to appear. Most patients suffer from abdominal pain and abdominal swelling. The symptoms of this kind of mesothelioma can also include nausea or weight loss, as well as fever. A lot of these symptoms are similar to those experienced by digestive issues, which could result in misdiagnosis.

Generally speaking, doctors can detect mesothelioma by conducting a thorough health history and physical exam. Imaging tests like X-rays and CT scans are a way to detect mesothelioma. These tests can identify tumors and other cancer signs which aren't visible on X-rays.

The results of these tests allow doctors to identify mesothelioma, and determine the stage. They can also recommend treatments. The staging is determined by the type of cell and whether or not the tumor has spread to other parts of the body.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in asbestos-containing occupations, like electrical or plumbing work, or in construction and manufacturing, are more likely to contract the disease. Even if they do not work in these areas, they can still be exposed to asbestos through family members or through other sources. This is why anyone who suspects they may be at risk should speak to an expert. A mesothelioma specialist can help those with a experience with asbestos to understand more about their risk.

Risk Factors

Asbestos is the main mesothelioma-related risk factor. It is responsible for up to 80% of all cases. Exposure to asbestos may occur as a result of work, military service, or through living with a person who works with asbestos or was previously exposed to doing such. When exposed to asbestos, the particles are able to be inhaled into abdomen and lungs. These particles irritate the linings of the abdomen, which causes cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include smoking, genetics and the advancing age. People in their 40s or 50s are at greater risk of developing mesothelioma compared to people who are younger or more. It is because mesothelioma generally takes 20 to 60 years from the initial exposure to asbestos before the first signs of cancer appear. It is also important to know that mesothelioma is a possibility in those who were exposed to asbestos but did not deal with it directly. This is known as indirect or secondary asbestos exposure and can be just as harmful as direct asbestos exposure.

Smoking increases the risk of mesothelioma, because it damages the mesothelium. It can also make it more vulnerable. Additionally, mesothelioma can be caused by certain illnesses, such as pneumonia and asbestosis. Men are more likely to develop mesothelioma compared to women. This is due to the fact that men are more likely to work with asbestos and have an extended period of exposure than women. Men are also more likely to live with someone who has was exposed to asbestos and bring stray asbestos fibers home on their clothing. Women are less likely to come into exposure to asbestos and do not typically carry asbestos home on their clothes.

Diagnosis

It is difficult to identify mesothelioma due to its symptoms being often similar to other diseases. This could lead to patients being wrongly diagnosed.

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

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart as well as a magnetic resonance imaging, or MRI test that uses radio waves and magnets to make a series of precise images of the inside of the body. A surgical biopsy is another way for doctors to diagnose mesothelioma. During a surgery biopsy doctors will remove a small piece of tissue from pleura or the peritoneum, to be tested further. A pathologist is then able to examine the tissue under microscopes to determine whether it contains cancerous cells.

The mesothelial type involved, the malignant or benign nature of these cells as well as the location, type and stage of the tumor, are used to categorize the disease. Certain mesothelioma types have a higher risk of spreading or metastasizing therefore it is essential to establish a clear diagnosis so doctors can treat it prior to it becoming out of control.

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

Treatment

A diagnosis of mesothelioma can be terrifying. However, it's important to remember that the cancer is treatable, especially in its initial stages. A lot of people suffering from mesothelioma be afflicted for many years without it expanding.

Exposure to asbestos legal (read this post from Danangplay) can trigger mesothelioma via many mechanisms. asbestos attorney fibres, small enough to not be felt or observed with the naked eyes are able to become airborne and irritate the lining of the lung (pleura). Over time, the irritation leads to the formation of scar tissue and eventually tumors.

The pleura covers the heart and lungs and the abdomen. Mesothelium is composed of cells that react to exposure to asbestos and cause it to enflame and form scar tissue. Overtime, these changes cause the development of malignant mesothelioma cancers.

The signs of pleural mesothelioma can include shortness of breath and chest pain, or a buildup of fluid on the lungs (pleural effusion). In rare cases, the cancer can grow to the tissues surrounding the heart and reproductive organs.

If imaging scans show a possible mass in the stomach or lungs, a doctor will order biopsies. During the procedure, doctors will remove tiny amounts of fluid or tumor for lab tests. The results can confirm the diagnosis of mesothelioma, and also determine the best treatment option.

There are a variety of mesothelioma treatments, which include chemotherapy, surgery, and immunotherapy. Most doctors utilize the combination of these methods. Patients may also benefit from taking part in a clinical trial of new mesothelioma treatments. To learn more, patients should speak with mesothelioma experts who have had experience treating the disease.
