The Cause of Mesothelioma Lung Cancer
Mesothelioma may begin in the layer of tissue that covers the lung (pleural mesothelioma) or in the tissue layer that covers organs in the tummy (peritoneal mesothelioma). The treatment options for mesothelioma are chemotherapy, surgery, and radiation.
Certain patients with mesothelioma aren't able to undergo surgery due to the stage of cancer. Other options for treatment include a drain that is placed in the pleura to reduce the accumulation of fluids and palliative medications to ease symptoms.
Asbestos
Asbestos is one of the fibrous minerals that are strong and heat-resistant. In the past they were used as insulation and construction materials. Workers who handled asbestos were at risk of breathing in asbestos fibers that could be stuck to the linings of the lungs. The asbestos fibers can remain in the lung and cause lung problems including mesothelioma.
The mesothelioma cancer affects the lining of organs known as the mesothelium. The linings of the lungs (pleura) are the most common site of mesothelioma. However, it may also develop in the linings in the abdomen (peritoneum) as well as the lining of the heart (pericardium). Mesothelioma is unique from other types of cancer because it typically takes between 10-50 years after exposure to asbestos before symptoms begin to be evident.
Mesothelioma is most likely to develop in those who have been exposed to asbestos during work. These include shipyard workers, construction workers, asbestos miners and other industrial jobs. The mesothelioma-related disease is often seen in veterans. the disease as a result of exposure to asbestos during their military service.
The people who worked in these high-risk occupations were exposed to asbestos in the construction of buildings, ships and vehicles. They also brought asbestos fibers to their homes on their uniforms, hair and tools. Families of those exposed to asbestos at work are also at risk of contracting mesothelioma and other illnesses. The secondhand exposure to asbestos is called secondary mesothelioma.
Other industries that have a high risk of exposure to asbestos include asbestos-related pipe fitters, asbestos-producing manufacturers, millwrights and asbestos contractors. These industries were primarily in the United States and used chrysotile asbestos, amosite asbestos and crocidolite as their main products. These industries also were at danger of exposure to asbestos whether on tools or clothing.
Exposure to radiation
Although asbestos is thought to be the most significant cause of mesothelioma lung cancer, radiation exposure is also associated with this disease. Mesothelioma patients who have been exposed to radiation are at an increased risk of developing the more aggressive mesothelioma called sarcomatoid which is more difficult to treat. This type of mesothelioma may affect the lungs, chest wall and the heart tissue. Radium exposure and other forms of radiation may increase a patient's risk for developing this type of mesothelioma.
Mesothelioma is a rare cancer that is difficult to identify. Patients may require numerous tests to determine if the disease is present. These tests can include a physical exam or imaging scans as well as a biopsy. A biopsy is the removal of a small amount tissue or fluid to determine mesothelioma.
Doctors employ a variety of radiation therapy to treat mesothelioma patients. They usually apply these treatments prior to or after surgery. They also make use of it to shrink tumors in patients who cannot undergo surgery. Radiation therapy is a treatment that uses high energy radiations, like gamma or X-rays to kill cancerous tissue by destroying their DNA.
Radiation therapy is used in the treatment of both pleural mesothelioma and melanoma due to its ability to kill cancerous cell and stop their spread. Radiation does not harm healthy tissues around it, as opposed to other forms of chemotherapy. When mesothelioma therapy is administered, doctors will place special shielding on the body of the patient to shield them from negative effects of the treatment.
It is often difficult for doctors to diagnose mesothelioma in a precise manner due to the latency period. Mesothelioma may be mistakenly diagnosed by doctors as a different lung cancer, or a common disease such as pneumonia or bronchitis. It is therefore crucial to inform your doctor about their asbestos exposure, so they can get regular checkups, and a mesothelioma diagnose when it occurs.
Genetics
Researchers have discovered that genetics play a part in mesothelioma. Mesothelioma affects only a small portion of people exposed to asbestos for a long period of time. Some studies show that mutations in certain genes that suppress tumors increase the chance that these people will develop mesothelioma.
Scientists are trying to figure out how these gene changes contribute to mesothelioma. They are examining how asbestos affects DNA and why some people have more mutations than those who have an asbestos history.
The first signs of mesothelioma might not manifest for up to 50 years following the initial exposure to asbestos. The first signs of the disease are usually breathlessness and chest pain. These symptoms are similar to those experienced by the pneumonia or flu and could easily be misinterpreted as other ailments. When symptoms begin to manifest the cancer has already expanded to the lungs. Mesothelioma is diagnosed in various stages, based on how far it has spread. The cancer could be present in the lung tissue, the lungs, or other organs.
Many patients with mesothelioma suffer from complications related to the cancer. The most frequent complications are respiratory failure and lungs that have collapsed. Other causes of death include lung infections, fluid buildup in the pleura or a tumor that extends into the what is mesothelioma caused by diaphragm or heart.
Many people who have mesothelioma have children who are affected by the disease. This has led to a debate over whether there is a link between mesothelioma and genetics. In the past, scientists believed that mesothelioma had a genetic component because children of parents with mesothelioma or other asbestos-related conditions were more likely to suffer from these illnesses. Recent research has proven that there is no genetic connection between mesothelioma or asbestos.
Doctors can test for mesothelioma by looking for the presence of cancer cells in a sample of fluid or tissue. They can also review the medical records of the patient to determine if they have a history of asbestos exposure. Doctors can also conduct an CT scan or MRI to locate the site of mesothelioma and its place within the body.
Lifestyle
Mesothelioma is a form of asbestos cancer that is found in the thin layer of tissue (mesothelium) that covers most internal organs. It most often affects the lung tissue (pleura). It may also occur in the lining around the abdomen or heart (peritoneal mesothelioma pericardial) or in the testicles. The doctors divide mesothelioma in stages based on the location of the cancer and the extent of it. The earlier mesothelioma is detected and treated, the more straightforward it is to treat.
A doctor can diagnose asbestosis by asking about the patient's medical history and examining for signs. They may also order an X-ray of the chest or a computed Tomography scan to look for calcium deposits in the pleura and lungs as well as signs of fluid in the chest cavity or changes in the diaphragm. They can also check the lymph nodes in the chest and abdominal areas for mesothelioma.
If a doctor suspects mesothelioma is present, they will perform a biopsied to confirm the diagnosis. They will also determine the stage of the cancer. The mesothelioma-specific type of cancer will also help doctors decide the best treatment option.
The majority of people diagnosed with pleural mesothelioma have a history of workplace exposure to asbestos. The exposure could have been from direct contact or indirect contact. Indirect exposure occurs when someone brings home the carcinogen that they the work they do on their clothes hair, skin or from contaminated tools. In the US approximately 80 percent of mesothelioma patients have been diagnosed as having been exposed to occupational asbestos. In the UK this number is around 50%.
There are many types of mesothelioma surgery that can improve your life quality and reduce symptoms. For pleural mesothelioma the most frequently performed operations are an extrapleural pneumonectomy or a pleurectomy with pulmonary decortication. These surgeries remove the cancerous pleura and the cancer as well as a portion of the diaphragm, lung and lining of the lungs. Some patients are candidates for an operation that is less invasive that involves the removal of the pleura, but only a small portion of the lung affected. These treatments are able to be utilized in conjunction to increase the patient's life expectancy.
