Mesothelioma and Asbestos

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

The symptoms of these diseases may not be evident for a long time after exposure to asbestos. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that occurs in the outer lung lining (pleura). It is the most prevalent mesothelioma that accounts for up between 70 and 79% of all diagnosed cases. This condition causes chest pain, shortness of breathe, and a feeling of heavyness.

Exposure to asbestos, a family of minerals comprised of microscopic fibers, typically causes this type of cancer. Once inhaled, these fibers cling to the lung and cause irritation which leads to scarring 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 symptoms are usually not apparent until 30 to 50 years after exposure.

The most frequent symptoms of pleural melanoma are chest discomfort and shortness of breath. Patients may also experience difficulty breathing or chest tightness. Patients with this type of cancer have a history of disease that includes asbestos exposure at work. The most common jobs that expose people to the risk of pleural mesothelioma include construction, manufacturing and shipbuilding. People who were in the military are at greater risk due the frequent use of asbestos attorneys in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system used for the pleural cancer. The stage that the patient is in at the time of diagnosis can help determine the treatment plan they will receive. Patients who have pleural mesothelioma which is in stage three or four will suffer a more negative outlook than those in a lower stage. Stage four mesothelioma can be spread to the heart, liver or diaphragm. This can make it more difficult to treat and increase the risk of complications for patients.

Peritoneal Mesothelioma

Contrary to pleural cancer that develops in the lung's lining the peritoneal cancer is a result of the membrane that covers the abdominal cavity, including organs like the liver and intestines. Like pleural mesothelioma, exposure to asbestos is the cause of peritoneal mesothelioma. The disease is much less prevalent than pleural mesothelioma. There are only about 300-500 cases diagnosed each year.

As with pleural asbestosis symptoms can take several years to manifest. Patients generally experience abdominal pain, and may also have a lump in their abdomen. The symptoms of this type of mesothelioma can also include nausea, weight loss and fever. A lot of these symptoms can be mistaken for gastrointestinal problems, leading to a false diagnosis.

Doctors can identify mesothelioma by examining the patient's medical history and conducting a physical exam. They can also use imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can reveal tumors as well as other signs of cancer that aren't evident on X-rays.

These test results enable doctors to diagnose mesothelioma and determine the stage. They also offer treatments. The stage of the disease is determined based on the type of cells and whether or the tumor has spread to other regions of the body.

The most significant risk factor for mesothelioma is exposure to asbestos. People who have worked in professions that require asbestos, like plumbing electrical work, manufacturing or construction, are at increased risk of developing the disease. However, even if individuals aren't employed in these fields, they can still be exposed to asbestos through relatives or other sources. Anyone who believes they may be at risk should consult an expert. If they have an history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in finding out more about the risk.

Risk Factors

Asbestos exposure is a major mesothelioma risk factor, accounting for up to 80 percent of cases. Exposure to asbestos can occur through work, military service, or living with people who have worked with asbestos. Asbestos particles are inhaled by people who are exposed to asbestos. The particles cause irritation to the linings, causing cancerous cells to grow in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics and aging. People in their 40s or 50s are at greater risk of developing mesothelioma compared to people who are younger or more. This is because mesothelioma usually takes 20 to 60 years from the initial time of exposure before the first signs of cancer appear. It is important to remember that mesothelioma may develop in people who have been exposed to asbestos, but did not engage directly with it. This is known as indirect or secondary exposure to asbestos and it is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, since it damages mesothelium. It also makes it more prone to. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. It is also important to remember that mesothelioma occurs more frequently in males than females. This is because men are more likely to work with asbestos and experience a more exposure than women. Men are also more likely to have lived with someone who had worked with asbestos, and Youtube.Com to have asbestos lawyer fibers on their clothing. Women tend to have less exposure to asbestos and rarely carry asbestos on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma since its symptoms are often similar to other conditions. Due to this, patients are sometimes mistakenly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background including asbestos exposure. Doctors may also request an CT scan or chest X-ray to look for abnormalities, lumps and evidence of exposure to asbestos. These include plaques on the pleura, pleura that are thickened and calcium deposits.

Other diagnostic tests include a magnetic resonance image, or MRI test, that uses radio waves and magnets to produce a series of precise images of the inside of the body. Another way doctors can diagnose mesothelioma is to perform a surgical biopsy. A surgical biopsy is when doctors remove a small piece of tissue from the peritoneum or pleura to conduct further tests. A pathologist can then look at the tissue under a microscope to see if it is contaminated with cancerous cells.

Mesothelioma is classified based on the type of mesothelial cell involved, whether these cells are malignant or benign and also the location of the tumor, the type, and the stage of the cancer. Certain mesothelioma types have a higher risk of spreading or metastasizing and it's crucial to get a definitive diagnosis to ensure that the doctors can treat it before it becomes out-of-control.

Doctors can also run laboratory tests on a tumor to identify specific genes, proteins or other elements that help them understand the cancer's characteristics and plan treatment. These results are referred to as staging.

Treatment

A diagnosis of mesothelioma can be terrifying. However, it is important to keep in mind that the cancer is treatable, particularly in its initial stages. Many mesothelioma patients live for many years with the disease without it spreading to other parts of their body.

Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos particles, which are too small to be able to see or feel through the naked eye, can become airborne and irritate the lining of the lungs (pleura). In time, the irritation leads to the formation of scar tissue that eventually result in tumors.

The pleura surrounds the lungs and the heart and the abdomen. Mesothelium is made up of cells that react to asbestos and cause it to enflame and create scar tissue. Overtime, these changes cause the development of malignant mesothelioma cancers.

A shortness of breath, chest discomfort or fluid buildup on the lungs are all signs of the pleural Msothelioma. In rare cases the cancer may spread to the tissues surrounding the heart and reproductive organs.

A doctor will request biopsy if imaging scans reveal a possible mass in the lungs or stomach. During the procedure, doctors remove small amounts of the fluid or tumor for laboratory tests. The results can confirm a mesothelioma diagnosis, and provide the best treatment option.

There are many types of mesothelioma treatment, which include chemotherapy, surgery, and immunotherapy. The majority of doctors employ a combination of these treatments. Patients can also benefit by participating in a clinical study of new mesothelioma treatment. To find out more, patients should speak with a mesothelioma specialist who has experience treating the condition.
