Mesothelioma and Asbestos

Asbestos is a natural mineral that is found in thin, long fibres. People who are exposed to asbestos are at risk of developing lung diseases, such as mesothelioma.

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

Pleural Mesothelioma

Pleural mesothelioma can be found in the lung's outer lining, also known as the pleura. It is the most prevalent form of mesothelioma and is responsible for 70 to 79% of diagnosed cases. Patients suffering from this condition suffer from chest pain and breath shortness and may also feel a sensation of heaviness in the chest.

This type of cancer often caused by exposure to asbestos, which is a cluster of minerals comprised of microscopic fibres. Once inhaled, the fibers are absorbed into the lungs and cause irritation that causes scarring and DNA mutations. Pleura surrounds both the chest cavity as well as the lungs, so irritations can also affect the heart. Mesothelioma is usually not symptomatic until 30 to 50 year after exposure.

Chest pain and shortness breath are the most common symptoms. Patients may also experience difficulty breathing, or chest tightness. Patients with this cancer have a history that includes manchester asbestos lawyer exposure at work. Construction, manufacturing and shipbuilding are the most common occupations which put people at risk risk of developing pleural mesothelioma. People who served in the military are at a higher risk due to the widespread use of asbestos in Navy vessels and Army bunkers.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most popular staging system used for the pleural adenocarcinoma. The stage that a patient is in at the time of diagnosis will help determine what treatment plan they should follow. For instance, patients who have mesothelioma pleural stage three or four have a worse prognosis than those with lower stages. Mesothelioma in stage four can develop into the liver, heart or diaphragm. This can make the cancer more difficult to treat and increase the chance of complications for patients.

Peritoneal Mesothelioma

Unlike pleural cancer, which forms in the lung's lining it develops in a membrane that surrounds the abdominal cavity, including organs such as the intestines and the liver. Similar to pleural mesothelioma and peritoneal mesothelioma is triggered by asbestos exposure. The disease is less prevalent than pleural mesothelioma, with around 300-500 cases being diagnosed each year.

As with pleural asbestosis, symptoms can take several years to show. Most patients are afflicted with abdominal pain as well as an abdominal mass. This mesothelioma type can cause nausea, weight loss, and fever. A lot of these symptoms can be mistaken for gastrointestinal problems which can lead to a misdiagnosis.

The doctors can detect mesothelioma through reviewing the medical history of the patient and performing a physical examination. Imaging tests such as X-rays or CT scans can be used to detect mesothelioma. These tests can reveal tumors and other symptoms of cancer that aren't visible on an X-ray.

These test results allow doctors to diagnose mesothelioma and determine the stage and recommend treatment options. Staging is determined based on the type of cell and whether or the tumor has spread to other parts of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have been in occupations that require asbestos, like plumbing or manufacturing, electrical work or construction, are at greater risk of developing the disease. Even if an individual isn't employed in any of these areas, he or she can still be exposed to asbestos through family members and other sources. Anyone who suspects that they are at risk should consult an expert. If they have an history of exposure to asbestos or mesothelioma, a specialist can help them find out more about the risk.

Risk Factors

Asbestos is the most significant mesothelioma-related risk factor. It accounts for up to 80percent of cases. Exposure to asbestos may occur as a result of work, military service or by living with a person who works with asbestos or used to do such. When exposed to asbestos, small particles can be inhaled into the lungs and abdomen. They can cause irritation to the linings of the abdomen and trigger cancerous cells to develop in the mesothelium. After asbestos exposure mesothelioma is likely to occur between 15 and 60 years old.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are at greater risk of developing mesothelioma as compared to 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 keep in mind that mesothelioma may be present in those who have been exposed to asbestos, but without having worked with it directly. This is referred to as indirect or secondary exposure to asbestos, and it is just as harmful as direct exposure.

Smoking increases the risk of mesothelioma, as it damages the mesothelium. It also makes it more prone to. Furthermore, mesothelioma is worsened by certain diseases like asbestosis and pneumonia. Men are more likely to develop mesothelioma than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and Vimeo to have worked with asbestos for longer durations and to work with it. Additionally, men are more likely to live with someone who was exposed to asbestos and bring norcross asbestos lawyer fibers from their workplace on their clothes. Women are less likely to come in contact with asbestos, and they are less likely to carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to identify because the symptoms often resemble other conditions. This could lead to patients being incorrectly diagnosed.

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

Other diagnostic tests include a magnetic resonance imaging or MRI test, which makes use of radio waves and magnets to create a series detailed images of the insides of the body. Another way doctors can diagnose mesothelioma is to perform the procedure of a surgical biopsy. During a surgical biopsy, doctors remove a small piece of tissue from the peritoneum or pleura for further testing. A pathologist can then examine the tissue with a microscope to see if it has cancerous cells.

Mesothelioma can be classified based on the type of mesothelial cells involved, whether these cells are malignant or benign and the location of the tumor, its type, and the stage of the tumor. Certain types of mesothelioma are at greater chance of metastasizing or spreading, so it's important to determine the type of mesothelioma so doctors can treat it before it gets out of control.

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

Treatment

A mesothelioma diagnosis can be a frightening prospect. However, it's important to remember that the cancer can be treated, particularly in its earlier stages. Many patients with mesothelioma endure the disease for many years without it expanding.

Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos particles, 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, the irritation causes the formation of scar tissue which causes changes in the cell structure that can eventually grow into tumors.

The pleura covers the heart and lungs, as well as the abdomen. Mesothelium is made up of cells that respond when exposed to asbestos. They inflame the tissue and cause it to become scarred. As time passes, these changes cause the development of malignant mesothelioma tumors.

Symptoms of pleural mesothelioma include breathing problems and chest pain, or a buildup of fluid in the lung (pleural effusion). In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.

If imaging scans reveal a possible mass in the lungs or stomach doctors will recommend biopsies. During the procedure doctors remove a small amount of fluid or tumor for tests in the laboratory. The results can confirm a mesothelioma diagnosis, and determine the best treatment option.

There are a variety of treatment for mesothelioma including surgery and chemotherapy. Most doctors rely on a combination of these methods. Patients may also benefit from enrolling in a clinical trial of new mesothelioma treatments. Patients can learn more by consulting a mesothelioma specialist who has treated mesothelioma.
