This Is The Mesothelioma And Asbestos Case Study You’ll Never Forget

Mesothelioma and Asbestos

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

It can take years for symptoms to show up after asbestos exposure. Different types of asbestos can cause different symptoms.

Pleural Mesothelioma

Pleural mesothelioma, a form of cancer, that develops in the lung’s outer lining (pleura). It is the most frequent mesothelioma that accounts for up between 70 and 79% of diagnosed cases. People with this condition suffer from chest pain and breath shortness and may experience the sensation of weight in the chest.

Exposure to asbestos, a family of minerals comprised of microscopic fibers, usually causes this type of cancer. Once inhaled, these fibers stick inside the lungs and cause irritation that causes scarring and DNA mutations. The pleura covers the chest cavity and lungs, so these irritations can affect both the lungs as well as the heart of a person. Mesothelioma symptoms are usually not apparent until 30 to 50 years after exposure.

The most frequent symptoms of pleural mesothelioma are chest pain and breath shortness. Some patients may also experience chest tightness, coughing or difficulty breathing. People with this cancer have a past that includes asbestos exposure at work. The most frequent jobs that expose people to the risk of pleural mesothelioma include manufacturing, construction and shipbuilding. People who have worked in the military could be at an especially high risk due to the frequent use of asbestos in Navy vessels and bunkers for the army.

The most commonly used staging method for pleural mesothelioma is the TNM (tumor, lymph nodes and metastases) staging system. The stage a patient has when they are diagnosed will assist their doctor in determining the best treatment plan for them. Patients suffering from pleural mesothelioma who is in stage three or stage four will have a less favorable prognosis compared to those who are in a less advanced stage. Stage four mesothelioma is often spread to the liver, diaphragm and/or a person’s heart. This can make it more difficult to treat and increase the chance of complications for the patient.

Peritoneal Mesothelioma

In contrast to pleural mesothelioma which develops in the lung lining, peritoneal mesothelioma forms in the peritoneum – an elongated membrane that covers the abdominal cavity and organs like the intestines and the liver. As with pleural mesothelioma exposure to asbestos is the cause of peritoneal msothelioma. Only 300-500 cases are diagnosed annually, which is less than the pleural asbestosis.

As with pleural asbestosis, symptoms can take years to manifest. Most patients are afflicted with abdominal pain as well as a mass in the abdomen. The symptoms of this type of mesothelioma may also include nausea as well as weight loss and fever. Many of these symptoms could be misinterpreted as digestive issues and can lead to a false diagnosis.

Doctors can identify mesothelioma by reviewing the medical history of the patient and performing a physical examination. They may also employ imaging tests like X-rays, CT scans and PET/CT scans to identify mesothelioma. These tests can show tumors and other symptoms of cancer that aren’t apparent on an X-ray.

These test results enable doctors to diagnose mesothelioma and establish the stage. They also offer treatment options. The staging is determined by the type of cells and whether or not the tumor has spread to other areas of the body.

The most significant risk factor for mesothelioma is asbestos exposure. People who have been in occupations that require asbestos, such as plumbing or manufacturing, electrical work or construction, are at greater risk of developing the disease. However, even if individuals aren’t employed in these areas they could be exposed to asbestos through relatives or other sources. Anyone who suspects that they may be at risk should talk to a doctor. If they have a history of asbestos exposure or mesothelioma, a specialist can help them find out more about their risk.

Risk Factors

Asbestos is the main risk factor in mesothelioma. It accounts for as much as the 80% of cases. Exposure to asbestos may occur due to work, military service or by living with someone who works with asbestos or was previously exposed to doing the same. When exposed to asbestos, particles can be breathed into the lungs and abdomen. These irritate the linings and can cause cancerous cells to develop in the mesothelium. Mesothelioma can take between 15 and 60 years to develop after exposure to asbestos.

Other risk factors include genetics, smoking and age. The people in their 40s or 50s are more at risk of developing mesothelioma as compared to people who are younger or more. 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 keep in mind, too, that mesothelioma may occur in those who have been exposed to asbestos, but without having directly worked with it. This is called 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. In addition, mesothelioma may be caused by certain illnesses, such as asbestosis and pneumonia. It is also important to know that mesothelioma is more prevalent in men than women. This is due to the fact that men are more likely to work with asbestos litigation and have more exposure than women. Additionally, men are more likely to live with someone who has had asbestos case exposure and bring asbestos fibers from their workplace on their clothes. Women are less likely to come in contact with asbestos, and don’t typically carry asbestos on their clothing.

Diagnosis

Mesothelioma is a difficult cancer to recognize because the symptoms often resemble other diseases. Because of this, victims are often wrongly diagnosed.

The first step in identifying mesothelioma is for NYU Langone doctors to perform a physical exam and take note of the medical history of the patient including asbestos exposure. Doctors can also order an X-ray chest or CT scan to look for lumps and other abnormalities, as well as evidence of past asbestos exposure like plaques on the pleura (thickened pleura with calcium deposits) and the buildup of fluid between the lung and chest wall (known as the pleural effusion).

Other diagnostic tests include a magnetic resonance image, or MRI test, which uses magnets and radio waves in order to create a series of detailed images of inside the body. A surgical biopsy is a different method for doctors to identify mesothelioma. During a surgical biopsy, doctors remove a small amount of tissue from the peritoneum or pleura for further testing. A pathologist can then look at the tissue under microscopes to determine whether it has cancerous cells.

The type of mesothelial cell involved and the benign or malignant nature of these cells, as well as the location, type and stage of the tumour, are used to categorize the disease. Certain types of mesothelioma are more likely to develop metastasis or spread which is why it is crucial to get a definite diagnosis so doctors can treat the disease before it goes out of control.

Doctors can also perform tests in the laboratory on tumors to determine specific genes, proteins, or other factors which can aid in describing cancer characteristics and plan treatment. These results are known as staging.

Treatment

A mesothelioma diagnosis can be an incredibly frightening prospect. But, it is crucial to remember that the disease can be treated, particularly in its initial stages. Many people with mesothelioma can live with the disease for a long time without expanding.

Exposure to asbestos can trigger mesothelioma through a variety of ways. Asbestos fibers, which are too small to see or feel by the naked eye can become airborne and irritate the lining of the lungs (pleura). In time irritation can lead to formation of scar tissue which causes changes in the structure of cells which eventually lead to tumors.

The Pleura is a protective layer that covers the lungs, heart and abdomen. Mesothelium is composed of cells that react to exposure to asbestos and cause it to enflame and create scar tissue. These changes eventually lead to malignant mesothelioma tumours.

A shortness of breath, chest pain or fluid accumulation on the lungs are all signs of pleural msothelioma. In rare cases the cancer may grow to the tissues surrounding the heart and reproductive organs.

If imaging scans show an underlying mass in the stomach or lungs, a doctor will order biopsies. The procedure involves the removal of small amounts of fluid or tumor to allow for laboratory testing. The results can confirm a mesothelioma diagnosis and determine the best treatment option.

There are a variety of treatment for mesothelioma including chemotherapy and surgery. The majority of doctors employ a combination of these treatments. Participating in clinical trials for new mesothelioma treatment may also be beneficial to patients. Patients can find out more by consulting a mesothelioma specialist who has treated the disease.
