Mesothelioma and Asbestos

Asbestos is a naturally occurring mineral that comes in long, thin fibres. Workers who are exposed asbestos regularly are at risk of developing mesothelioma as well as other lung diseases of different types.

It can take years before symptoms begin to manifest after asbestos; www.Sangsuk.org, exposure. 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 mesothelioma that accounts for up 70 to 79% of all diagnosed cases. Patients suffering from this condition suffer from chest pain and breath shortness, and they may feel a sensation of heaviness in the chest.

This kind of cancer is usually caused by exposure to asbestos which is a grouping of minerals that are comprised of microscopic fibres. When inhaled, these fibers stick inside the lungs and cause irritation that leads to scarring and DNA mutations. The pleura covers the lungs and chest cavity, so these irritations can affect both the lungs as well as the heart of a person. Mesothelioma typically doesn't manifest until 30 to 50 years after exposure.

The most commonly reported symptoms of pleural mesothelioma are chest pain and breath shortness. Patients may also experience difficulty breathing or chest tightness. Patients with this cancer have a history of disease that includes asbestos exposure at work. The most prevalent jobs that expose workers to the risk of pleural mesothelioma include manufacturing, construction and shipbuilding. Individuals who have served in the military are at higher risk due to the frequent use of asbestos in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes and metastases staging system) is the most commonly used staging system for pleural adenocarcinoma. The stage a patient has upon diagnosis will aid their doctor in determining the most appropriate treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or stage four will suffer a more negative prognosis compared to those who are in a lower stage. Stage four mesothelioma may develop into the liver, heart or diaphragm. This makes it more difficult to treat and increase the likelihood of complications for the patient.

Peritoneal Mesothelioma

Unlike pleural mesothelioma, which develops in the lung lining, peritoneal mesothelioma develops in the peritoneum, it is a membrane that lines the abdominal cavity as well as organs like the liver and intestines. Like pleural mesothelioma, peritoneal mesothelioma is caused by asbestos exposure. Only 300-500 cases are diagnosed annually which is lower than pleural asbestosis.

Like pleural mesothelioma, the symptoms can take years to show. Patients generally have abdominal pain, and may have a mass in their abdomen. This kind of mesothelioma can also cause nausea, weight loss, and fever. Many of these symptoms are similar to symptoms of digestive issues, which could cause confusion in diagnosis.

Generally speaking, doctors can detect mesothelioma after an extensive health history and physical exam. They may also employ imaging tests such as X-rays, CT scans and PET/CT scans to help find mesothelioma. These tests can show tumors and other symptoms of cancer that aren't apparent on an X-ray.

These tests enable doctors to diagnose mesothelioma and determine the stage of the disease and suggest treatment options. The stage of the disease is determined based on the type of cells and whether or whether the tumor has spread to other regions of the body.

asbestos law exposure is the biggest risk factor. People who have worked in asbestos-related occupations, like plumbing or electrical work, or in construction and manufacturing, are more likely to develop the disease. However, even if people do not work in these areas they could be exposed to asbestos through family members or other sources. Anyone who thinks they may be at risk should consult a doctor. If they have an history of exposure to asbestos and mesothelioma is a concern, a specialist will assist them in finding out more about their risk.

Risk Factors

Asbestos exposure is the main risk factor for mesothelioma making up as much as 80 percent of cases. Exposure to asbestos may occur through work, military service, or living with someone who used to work with asbestos. Asbestos particles are inhaled by people who are exposed to it. These irritate the linings and cause cancerous cells to form in the mesothelium. Mesothelioma may take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include smoking, genetics, and the advancing age. People in their 40s and 50s are more likely develop mesothelioma than those who are younger or more senior. It is because mesothelioma generally takes 20 to 60 years after the initial exposure before the first signs of cancer appear. It is important to remember that mesothelioma can occur in those who have been exposed to asbestos, but without having been directly exposed to it. This is referred to as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking increases the chance of mesothelioma because it damages the mesothelium. It can also make it more vulnerable. Mesothelioma is also aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to note that mesothelioma occurs more frequently in men than women. Men are more likely than women to have been exposed to asbestos for longer periods of time and to have worked with asbestos for longer durations and to work with it. Men are also more likely to live with someone who has worked with asbestos and carry stray asbestos fibers home on their clothing. Women tend to be less in contact with asbestos, and don't typically carry asbestos on their clothes.

Diagnosis

Mesothelioma is a difficult disease to identify because the symptoms can be similar to other diseases. This can lead to victims being incorrectly diagnosed.

NYU Langone doctors will perform a physical examination and record the patient's medical background, including asbestos exposure. Doctors may also order an X-ray chest or CT scan to look for lumps or other abnormalities, as well as evidence of previous asbestos exposure like plaques on the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and the 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 uses radio waves and magnets to create detailed images of the inside of the body. A surgical biopsy is a different way for doctors to diagnose mesothelioma. In a surgical biopsy doctors take a small amount of tissue from the pleura or peritoneum for further testing. A pathologist then examines the tissue using a magnifying lens to determine if it is a cancerous cells.

The type of mesothelial cells involved and the benign or malignant nature of the cells, as well as the location the cancer, its type and the stage of the cancer are used to categorize the disease. Certain types of mesothelioma are at greater chance of metastasizing or spreading and it's crucial to get a definitive diagnosis to ensure that the doctors can treat it before it becomes out of control.

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

Treatment

A diagnosis of mesothelioma may be frightening. It is crucial to remember that cancer can be treated, particularly in its early stages. Many people with mesothelioma live for a long time with the disease, without spreading to other organs of their body.

Exposure to asbestos can cause mesothelioma in many ways. Asbestos fibres, tiny enough to be felt or observed by naked eyes are able to become airborne, irritating the lung's lining (pleura). Over time irritation can lead to formation of scar tissue which causes changes in the structure of cells that eventually develop into tumors.

The pleura is a protective covering that surrounds the lungs, heart and abdomen. Mesothelium consists of cells that react to asbestos legal which causes it to become inflamed and create scar tissue. As time passes, these changes result in the growth of malignant mesothelioma cancers.

Shortness of breath, chest discomfort or fluid buildup on the lungs are all symptoms of pleural msothelioma. In rare instances the cancer may grow to the tissues surrounding the heart and reproductive organs.

If scans of imaging reveal an underlying mass in the stomach or lungs, a doctor will order biopsies. During the procedure, doctors take a small sample of the fluid or tumor for laboratory testing. The results will confirm a mesothelioma diagnosis, and indicate the most effective treatment plan.

There are many types of treatment for mesothelioma including surgery and chemotherapy. Most doctors utilize the combination of these treatments. Patients can also benefit by enrolling in a clinical trial of new mesothelioma treatments. Patients can learn more about the trials by consulting a mesothelioma specialist who has treated the disease.
