Mesothelioma and Asbestos

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

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

Pleural Mesothelioma

Pleural mesothelioma is a cancer that affects the outer lung lining (pleura). It is the most common form of mesothelioma and is responsible for 70 to 79% of diagnosed cases. Patients with this disease feel chest pain and breathlessness and may experience an ache or heaviness in the chest.

This type of cancer typically caused through exposure to asbestos, which is a cluster of minerals that are composed of microscopic fibers. Once inhaled, the fibers are absorbed into the lung and cause irritation which causes scarring and DNA mutations. The pleura surrounds the lungs and chest cavity This means that these irritations can affect both the lungs and a person's heart. Mesothelioma usually doesn't show symptoms until 30 to 50 years after exposure.

Shortness of breath and chest pain are the most common symptoms. Patients may also experience chest tightness, coughing or difficulty breathing. Patients with this type of cancer have a history that includes asbestos exposure at work. The most frequent jobs that expose people to the risk of developing pleural cancer are manufacturing, construction, and shipbuilding. Individuals who have served in the military are at greater risk due the frequent use of asbestos lawyer in Navy vessels and bunkers in the Army.

The TNM (tumors lymph nodes, tumors, and metastases staging system) is the most commonly used staging system for the pleural cancer. The stage that the patient is in at the moment of diagnosis will determine the treatment plan they should follow. Patients suffering from pleural mesothelioma who is in stage three or four will have a less favorable prognosis than those who are in a less advanced stage. Stage four mesothelioma can develop into the heart, liver or diaphragm. This can make it more difficult to treat and raises the risk of complications for the patient.

Peritoneal Mesothelioma

Contrary to pleural cancer which is found in the lining of the lung the peritoneal cancer is a result of a membrane that covers the abdominal cavity, which includes organs such as the liver and intestines. As with pleural mesothelioma asbestos exposure is the primary reason for peritoneal msothelioma. The disease is less prevalent than pleural mesothelioma. There are around 300-500 cases being diagnosed each year.

Like pleural mesothelioma, symptoms may take years to appear. Patients typically suffer from abdominal pain and could also experience a mass in their abdomen. This type of mesothelioma may cause nausea, weight loss and fever. Many of these symptoms could be misinterpreted as digestive issues which can lead to a misdiagnosis.

Doctors can detect mesothelioma by looking over the medical history of the patient and performing a physical examination. Imaging tests like X-rays and CT scans can be used to identify mesothelioma. These tests can reveal cancerous tumors or other signs of cancer that aren't apparent on an X-ray.

These test results allow doctors to diagnose mesothelioma, identify the stage and suggest treatment options. Staging is determined based on the type of cell and whether or the cancer has spread to other regions of the body.

The most important mesothelioma-related risk factor is exposure to asbestos. People who have worked in jobs that require asbestos, such as plumbing manufacturing, electrical work or construction, are at a higher risk of developing the disease. Even if they do not work in these fields they may be exposed to asbestos through family members or other sources. Anyone who suspects that they may be at risk should speak with an expert. If they have any history of exposure to asbestos or mesothelioma, a specialist can help them find out more about their risk.

Risk Factors

Asbestos is the most significant mesothelioma-related risk factor. It is responsible for as much as the 80% of cases. Exposure to asbestos can occur as a result of work, military service, or living with someone who used to work with asbestos compensation. When exposed to asbestos, the particles can be breathed into the lungs and abdomen. These particles can cause irritation to the linings and cause cancerous cells to grow in the mesothelium. Mesothelioma can take between 15 and 60 years to develop following exposure to asbestos.

Other risk factors include genetics, smoking and age. People in their 40s and 50s are more likely get mesothelioma than people younger or older. This is because mesothelioma typically lasts between 20 and 60 years after the initial time of exposure before the first signs of cancer appear. It is important to remember, too, that mesothelioma can develop in people who have been exposed to asbestos, but without having worked with it directly. This is referred to as indirect or secondary asbestos exposure. It can be as hazardous as direct asbestos exposure.

Smoking can increase the likelihood of getting mesothelioma because it damages the mesothelium, which makes it more vulnerable to asbestos case (have a peek at this web-site). Mesothelioma can also be aggravated by certain illnesses, including asbestosis and pneumonia. It is also important to note that mesothelioma is more prevalent in men than women. Men are more likely than women to have been exposed to asbestos for a longer time and to have worked with it. Men are also more likely to have lived with someone who has been exposed to asbestos, and to have asbestos-containing fibers on their clothing. Women tend to be less in contact with asbestos, and don't typically bring asbestos home on their clothing.

Diagnosis

It is difficult to diagnose mesothelioma due to its symptoms being often similar to other conditions. Because of this, victims are often mistakenly diagnosed.

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

Other diagnostic tests include an echocardiogram, which examines the heart and blood vessels, and a magnetic resonance imaging, also known as MRI, test, which makes use of radio waves and magnets to make a series of precise images of the inside of the body. Another way for doctors to detect mesothelioma is through the procedure of a surgical biopsy. During a surgery biopsy, doctors remove a tiny piece of tissue from the pleura or the peritoneum to be further examined. A pathologist can examine the tissue with a microscope to see if it contains cancerous cells.

Mesothelioma is classified according to the type of mesothelial cell involved, whether those cells are benign or malignant, and the location of the tumor, its type, and the stage of the tumor. Some types of mesothelioma are more likely to develop metastasis or spread which is why it is crucial to establish a definitive diagnosis to ensure that doctors are able to treat the disease before it becomes out of control.

Doctors can also run tests in the laboratory on tumors to determine particular proteins, genes, or other factors which can help them identify the characteristics of the cancer and determine a treatment. These results are known as staging.

Treatment

A diagnosis of mesothelioma may be frightening. But, it is crucial to remember that the cancer is treatable, particularly in its earlier stages. Many people with mesothelioma can endure the disease for many years without it spreading.

Exposure to asbestos can cause mesothelioma through a variety of ways. Asbestos fibers that are small enough to not be felt or viewed by naked eyes, can become airborne, irritating the lung's lining (pleura). Over time the irritation causes the formation of scar tissues that eventually result in tumors.

The pleura is a protective covering that protects the abdomen, heart, and lungs. Mesothelium consists of cells that react when exposed to asbestos. They inflame the tissue and cause it to scar. Overtime, these changes lead to the development of malignant mesothelioma cancers.

Breathing problems, chest discomfort or fluid buildup on the lungs are all signs of pleural msothelioma. In rare cases, the cancer can be spread to the tissues around the heart and reproductive organs.

If scans of imaging reveal an area of concern in the stomach or lungs doctors will recommend biopsies. During the procedure doctors remove some of the liquid or tumor for tests in the laboratory. The results can confirm a mesothelioma diagnosis, and determine the best treatment plan.

There are many types of treatment for mesothelioma such as chemotherapy and surgery. Most doctors use the combination of these treatments. Patients can also benefit by enrolling in a clinical trial of new mesothelioma therapies. To learn more about the trials, patients should speak with mesothelioma experts who have had experience treating the disease.
