Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in thin, long fibres. Workers who are exposed to asbestos on a regular basis are at risk of developing mesothelioma as well as other lung diseases.

It could take a long time before symptoms begin to manifest after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma is a cancer that occurs in the outer lung liner (pleura). It is the most frequent type of mesothelioma, making up 70 to 79% of diagnosed cases. The condition can cause chest discomfort, shortness of breath and a feeling heavyness.

Exposure to asbestos, a class of minerals comprised of microscopic fibers, typically causes this kind of cancer. When inhaled, these fibers, cause irritation and DNA mutations. Pleura is the lining of both the chest cavity as well as the lungs, and so irritations can also affect the heart. Mesothelioma usually doesn't show symptoms until 30 to 50 year after exposure.

Chest pain and shortness breath are the most frequent 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 manufacturing, construction, and shipbuilding. Individuals who have served in the military are at greater risk due to the extensive use asbestos in Navy vessels and Army bunkers.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient is in at diagnosis will assist their doctor in determining the best treatment plan for them. For instance, patients suffering from a pleural mesothelioma in stage three or four have a poorer prognosis than those in a lower stage. Stage four mesothelioma may develop into the heart, liver or diaphragm. This could make the cancer more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum -- it is a membrane that lines the abdominal cavity and organs like the intestines and liver. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. The disease is much less prevalent than pleural mesothelioma. There are only about 300-500 cases diagnosed each year.

As with pleural mesothelioma symptoms may take years to appear. Patients generally suffer from abdominal pain and may also have a lump in their abdomen. This mesothelioma type can cause nausea, weight loss, and fever. A lot of these symptoms are similar to those of gastrointestinal issues, which can cause misdiagnosis.

Doctors can detect mesothelioma by examining the patient's medical history and performing a physical exam. Imaging tests like X-rays or CT scans are a way to identify mesothelioma. These tests can detect tumors and other cancer signs that aren't visible on X-rays.

The results of these tests allow doctors to diagnose mesothelioma and determine the stage. They can also suggest treatment options. The stage of the disease is determined based on the cell type and whether or the cancer has spread to other regions of the body.

Asbestos exposure is the most important risk factor. People who have worked in professions which require asbestos, such as plumbing manufacturing, electrical work, or construction, are at greater risk of developing the disease. However, even if people do not work in these fields, they can still be exposed to asbestos through family members or other sources. This is why anyone who believes they could be at risk should talk to a doctor. If they have any history of exposure to asbestos, a mesothelioma specialist can assist them in learning more about their risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma accounting for up to 80 percent of all cases. Exposure to asbestos can occur due to work, military service, or by living with a person who is exposed to asbestos or used to do such. Asbestos particles are inhaled by those who are exposed to asbestos lawsuit. They can cause irritation to the linings of the abdomen and cause cancerous cells to form in the mesothelium. Mesothelioma can take anywhere 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 and 50s are more likely to be diagnosed with mesothelioma compared to those who are younger or more senior. Mesothelioma can take between 20 and 60 years before it manifests cancer symptoms after the first exposure. It is also important to know that mesothelioma may develop in people who were exposed to asbestos but didn't work with it directly. This is called secondary or indirect exposure to asbestos, and it could be as hazardous as direct exposure.

Smoking increases the chance of mesothelioma developing, as it damages the mesothelium. It also makes it more susceptible. Furthermore, mesothelioma is worsened by certain diseases like pneumonia and asbestosis. It is also important to note that mesothelioma is more prevalent in males than females. Men are more likely than women to have been exposed to asbestos for longer periods of time and to work with it. Men are also more likely to have lived with someone who had worked with asbestos and to have asbestos-containing fibers on their clothing. Women are less likely to come exposed to asbestos, and they don't usually bring asbestos home on their clothes.

Diagnosis

It is difficult to recognize mesothelioma since its symptoms are often similar to other diseases. This is why patients are often mistakenly diagnosed.

The first step in diagnosing mesothelioma is for NYU Langone doctors to perform a physical exam and take notes on the medical history of a patient including asbestos exposure. Doctors can also order a chest X-ray or CT scan to detect 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 chest wall (known as pleural effusion).

Other diagnostic tests include an echocardiogram, which examines the blood vessels and the heart, and a magnetic resonance imaging, also known as MRI test that uses magnets and radio waves to make a series of detailed images of the interior of the body. A surgical biopsy is yet another way for doctors to diagnose mesothelioma. In a surgical biopsy doctors take a tiny part of tissue from the pleura or the peritoneum, to be tested further. A pathologist can look at the tissue under a microscope to see if it has cancerous cells.

Mesothelioma is classified based on the type of mesothelial cells involved, whether those cells are malignant or benign and the location of the tumor, the type, and the stage of the cancer. Certain types of mesothelioma are at an increased risk of spreading or metastasizing therefore it is essential to determine the type of mesothelioma so doctors can treat it before it becomes out-of-control.

Doctors may also conduct laboratory tests on a tumor to identify particular proteins, genes and other factors that can help them describe the characteristics of cancer and plan treatment. These results are called staging.

Treatment

A mesothelioma diagnosis is a frightening prospect. However, it is important to keep in mind that the cancer is treatable, particularly in its early stages. A lot of people suffering from mesothelioma endure the disease for many years without it expanding.

Exposure to asbestos case - hop over to this site, can cause mesothelioma through a variety of mechanisms. asbestos lawyer fibres, small enough to not be felt or viewed with the naked eyes can be airborne, causing irritation to the lung's lining (pleura). Over time irritation leads to formation of scar tissue, which causes changes in the structure of cells that can eventually grow into tumors.

The Pleura is a covering that surrounds the lungs, heart and abdomen. Mesothelium is made up 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 signs of pleural mesothelioma can include breathlessness and chest pain as well as the accumulation of fluid in the lungs (pleural effusion). In rare cases cancer may spread to the tissues that surround the reproductive organs as well as the heart.

A doctor will request biopsy if scans show the possibility of a mass in the lungs or stomach. During the procedure, doctors remove small amounts of the fluid or tumor for lab testing. The results can confirm the diagnosis of mesothelioma and help determine the best treatment option.

There are many types of treatment for mesothelioma, including chemotherapy and surgery. Most doctors utilize the combination of these methods. Participating in clinical trials for mesothelioma treatments may be beneficial to patients. To find out more, patients should speak with mesothelioma experts who have experience treating the condition.
