Mesothelioma and Other Asbestos Related Cancers

People who have had previous exposure to asbestos are at risk for several types of cancer such as mesothelioma. These diseases have a lengthy time of latency, which means that symptoms do not manifest for years after exposure.

The risk of developing pleural and mesothelioma peritoneal diminishes with time since the first exposure. The evidence is drawn from six cohort studies of occupational exposure and two residential cohorts that have long-term following.

What is Mesothelioma?

Mesothelioma refers to cancer of the lining of internal organs, including the lung (pleural mesothelioma) or abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It's a rare, aggressive disease that usually begins in the lining of the chest cavity, but it can also be found in the stomach's lining or in other parts of the body. Asbestos exposure is the main cause of mesothelioma, and the cancer is usually not able to show up until decades after the initial exposure.

People who are exposed to asbestos at work have a higher risk of developing the disease than other. Asbestos fibers can be inhaled or swallowed and bind to the organ's lining. They irritate the lining of the organs, causing abnormal cells to multiply and develop into tumors. The symptoms usually don't manifest until a person has advanced mesothelioma.

Exposure to asbestos most often is found in industrial settings in which workers handled the material or were in close proximity to it. Asbestos is used in a variety of trades, including construction, shipbuilding and auto repair. Veterans who were in the military are at particular risk of developing mesothelioma because asbestos was widely used on ships and bases.

Patients with a exposure to asbestos need to be checked regularly, and should be alert for any unusual symptoms. If a doctor suspects mesothelioma they could request imaging tests such as CT scans, MRI or PET scans to check for tumors and determine if they have expanded. They may also perform physical examinations and inquire about a patient's exposure to asbestos history. Certain cases of mesothelioma may be caused by genetic changes. So, certain patients could benefit from genetic tests.

Risk Factors

The main mesothelioma-related risk is exposure to asbestos. Asbestos, a mineral made up of fibers, is resistant to heat and is strong. Asbestos was utilized in a variety of construction and manufacturing products including insulation, brakes and shingles. Asbestos dust can be inhaled and swallowed if disturbed. Over time, this can lead to irritation of the mesothelium, which can ultimately develop into mesothelioma.

Mesothelioma occurs most often for those with had a history of occupational exposure to asbestos. This includes those who worked in fields such as mining, shipbuilding construction, and automotive repair. Veterans of the military are also at risk since many branches of the military used asbestos-based materials.

A family history of asbestos and radiation therapy for chest cancer are other factors that can increase the risk of mesothelioma. In addition, the mesothelioma type that is diagnosed has a significant impact on the risk. Pleural mesothelioma is the most prevalent form and typically affects the lungs. Other mesothelioma forms include testicular, pericardial and peritoneal.

In general mesothelioma is a cancer that increases with the third to fourth power of latency - which is the length of time it takes for a patient to be diagnosed. The incidence of pleural cancer has an apparent flattening after 40 years. Peritoneal and pericardial mesothelioma both exhibit this trend too. People who have a para-occupational exposure to asbestos, such as living close to an asbestos plant or eating contaminated household products - are also at increased risk for mesothelioma. In a study of six cities in the United States, those who were exposed to asbestos in this way were at a higher risk of mesothelioma than people who had only occupational exposure.

Symptoms

Malignant mesothelioma affects the tissue linings surrounding internal organs. It is most often found in the lung lining (pleura) and abdomen (peritoneum). Mesothelioma can also develop in the lining around the testicles or heart. It is a rare form of cancer, and the majority of people diagnosed with mesothelioma were employed in jobs which exposed them to asbestos. The signs of mesothelioma may take years to manifest and the condition is not curable.

Asbestos is a class of minerals that have thin microscopically-sized fibers that are resistant to heat, fire, and chemicals. It is extensively used in many industries, including shipbuilding construction, manufacturing and many more. Exposure to asbestos may cause mesothelioma, because the fibers may get stuck in tissues lining and protect organs. This causes irritation and damages to cells. This can lead to tumors expanding and eventually becoming cancerous.

The most frequent mesothelioma type is called mesothelioma pleural, which occurs in the lung's lining (pleura). It can also develop in the lining of the testicles or heart or in the lining of your abdomen (peritoneum). Mesothelioma can also spread to the lymph nodes, causing them to swell.

Most people diagnosed with mesothelioma are victims of exposure to asbestos and also suffer from other diseases like chronic pulmonary disease. The symptoms of mesothelioma are similar to those of other conditions, so it is important to visit a doctor if you are experiencing persisting or alarming signs and symptoms. Doctors will ask about your past asbestos exposure and may conduct physical examination. They can also request scans of your blood and imaging of your abdomen or chest. These can identify any thickening of the lung's lining or the fluid that is leaking out of the space between your lungs as well as the chest wall.

Diagnosis

Asbestos fibers that are entangled on the body can cause harm and may eventually grow into cancerous tumors. Different kinds of asbestos-related cancers develop in various tissues or organs and can be identified using different tests. Mesothelioma can occur in the linings of the chest cavity, lungs, stomach (peritoneum) or around the reproductive organs, such as the heart or reproductive system.

To determine if mesothelioma is a cancer the patient must consult with their physician about the history of asbestos exposure they have experienced and any symptoms they may be experiencing. Doctors can also conduct physical examinations and tests to determine the health of the lungs.

X-rays and CT scans help doctors get a clearer picture of the affected area. In some cases, doctors use a Pleural Fluid Test to determine if mesothelioma may be causing the fluid buildup. Pleural effusions can be a sign of pleural, peritoneal or mixed mesothelioma.

Mesothelioma is often misdiagnosed due to the symptoms are similar to those of other diseases and conditions. The most common symptoms are chest pain and breathing problems. Pleural mesothelioma may also cause fatigue, chest tightness and cough. Peritoneal mesothelioma can cause abdominal pain swelling and distension. Testicular mesothelioma could manifest as a swollen itchy lump on the testicles.

Researchers are studying the presence of proteins in blood to find methods to detect mesothelioma at an early stage. They are also studying a number other tests and procedures that could improve the accuracy of diagnosis. This includes mesothelioma scans and MRIs. They are also researching genetic mutations and ways to determine if someone is at risk of developing mesothelioma by looking at their family history.

Treatment

Asbestos exposure is the main risk factor for mesothelioma. Anyone who has worked with asbestos in the past, specifically for prolonged periods of time or in high risk jobs such as shipbuilding, electrical work, military service and auto repair are at a higher risk.

Exposure to asbestos can cause mesothelioma. The fibers get stuck in the tissue that lines vital organs and protects them. The fibers cause irritation to the mesothelium and cause DNA damage that leads to cancerous cells. The symptoms of mesothelioma typically do not appear for decades after exposure.

The symptoms of mesothelioma vary depending on its type and location in the body. Most mesothelioma cases involve the lining of the lungs (pleural mesothelioma) however, it can be found in the lining of the stomach (peritoneal mesothelioma) and the heart (pericardial mesothelioma) or testicles (testicular mesothelioma).

Mesothelioma staging helps doctors determine treatment options. The disease is categorized as stages I to IV, with stage I and II being the first stages and the most manageable. Stage III and stage IV are the later stages of cancer, and are more difficult to treat. However there are still many options for treatment.

Pleural mesothelioma is the most frequent form of the disease and affects the lung lining and chest wall, as well as the abdomen. The majority of cases of pleural mesothelioma are the result of asbestos compensation exposure during work. This is most likely because of breathing in asbestos particles from the air or ingestion of the cancerous substance through the food chain.

Other risk factors include genetic mutation in the family or prior treatment for a different ailment. It is crucial to talk with a doctor if you have symptoms of mesothelioma and were exposed to asbestos claim. You could also benefit from genetic counseling. A mesothelioma specialist can assist you in filing a lawsuit against companies who have wrongfully used asbestos in everyday products.
