Mesothelioma and Other Asbestos Related Cancers
People who have previous exposure to asbestos are at risk of developing various types of cancer such as mesothelioma. These diseases have a lengthy latency period, meaning symptoms don't manifest until decades after exposure.
The risk of developing pleural or peritoneal msothelioma decreases with time after first exposure. The evidence is drawn from six cohort studies of occupational exposure and two residential cohorts with long-term following.

Mesothelioma or cancer of the inner organs' linings like the lung (pleural) or abdomen (peritoneal) and the heart (pericardial) is a rare and aggressive disease. It is a rare and dangerous disease that typically starts in the lining in the chest cavity. However, it can also affect the lining of the stomach and other areas of your body. Asbestos exposure is the main reason for mesothelioma, and the cancer is usually not able to appear until decades after the initial exposure.
People who are exposed to asbestos at work have a higher risk of getting the disease than others. Asbestos fibers can be inhaled or swallowed and adhere to the lining of organs. They irritate the lining of the organs, causing abnormal cells to multiply and develop into tumors. Symptoms usually do not appear until a person has developed mesothelioma that is advanced.
Exposure to asbestos most often is found in industrial settings where workers handled the substance or were in close proximity to it. Asbestos is used in many trades, including shipbuilding, construction, and auto repair. Veterans who were in the military are particularly at risk of developing mesothelioma because asbestos was used extensively on ships and bases.
People with a past exposure to asbestos need to be checked regularly and be alert for any unusual symptoms. If a doctor suspects mesothelioma they may order imaging scans, such as CT scans or MRI scans to check for tumors and determine if they've gotten larger. They can also inquire about the patient's past history of asbestos exposure and perform an examination. Certain mesothelioma cases are linked to genetic changes, and therefore certain patients could benefit from genetic tests.
Risk Factors
The main risk factor for mesothelioma is exposure to asbestos. Asbestos is a mineral made of tiny fibers that are strong and withstand heat. Asbestos was employed in a variety of manufacturing and construction products, including insulation, brakes and shingles. When asbestos is disturbed it creates dust that may be swallowed or inhaled. This can cause irritation to the mesothelium over time, which could eventually lead to mesothelioma.
Mesothelioma occurs most often in those with an occupational history of exposure to asbestos. This includes people who have worked in industries like construction, shipbuilding, mining and auto repair. Military veterans are also at risk, as many branches of the military use asbestos-based products.
A family history of asbestos and radiation therapy to the chest are other factors that can increase the risk of mesothelioma. The type of mesothelioma that is diagnosed has a significant impact on risk. The most common mesothelioma that is one that affects the lung. Other mesothelioma types include the peritoneal (pericardial) testicular, testicular, and peritoneal.
In general mesothelioma is a cancer that increases with the third to fourth power of latency - which is the time it takes for someone to get diagnosed. The incidence of pleural cancer has a slight flattening after 40 years. Both peritoneal and pericardial mesothelioma show the same trend. Exposure to asbestos in the workplace like living near an asbestos plant or eating food products contaminated by asbestos, can also increase the risk of mesothelioma. In an investigation of six cities in the United States, those who were exposed to asbestos in this way were more likely to develop mesothelioma than people who only had occupational exposure.
Signs and symptoms
The internal organs' linings are affected by malignant mesothelioma. It is most often found in the linings of the lungs and abdomen. Mesothelioma can also form in the lining of the testicles or heart. It is a rare form of cancer and the majority of patients diagnosed with mesothelioma have worked in positions that exposed them to asbestos. The symptoms of mesothelioma can take years to manifest, and the condition is not curable.
Asbestos is one of the minerals with tiny microscopically-sized fibers that are resistant to heat, chemicals, and fire. It was once widely used in construction, shipbuilding manufacturing, and other industries. Exposure to asbestos can cause mesothelioma because the fibers get stuck in the tissues that line and protect organs which causes irritation and damage to cells. This can cause tumors to grow and eventually become cancerous.
The most commonly encountered mesothelioma type is mesothelioma pleural, which occurs in the lining of the lungs (pleura). It may also start in the lining of the heart or testicles, or the lining of your abdomen (peritoneum). Mesothelioma can also expand to lymph nodes and cause swelling of the lymph nodes.
The majority of people diagnosed with mesothelioma had an extensive history of exposure to asbestos and are suffering from other ailments such as chronic lung disease. Symptoms of mesothelioma can be similar to other illnesses and it is therefore important to consult a doctor when you observe any persistent or worrying signs and symptoms. Doctors will ask about your asbestos exposure in the past and may perform physical examination. They can also request scans of your blood and imaging of your chest or abdomen. They can reveal any thickening of the lung's lining, or fluid in the space between your lungs and chest wall.
Diagnosis
If asbestos fibers get stuck to the body, they can cause damage and may eventually develop into cancerous tumors. Asbestos-related cancers can develop in a variety of organs and tissues. Each type of cancer can be identified by a specific test. Mesothelioma can be found in the linings of the chest cavity, lungs and stomach (peritoneum) or around the heart or reproductive organs.
To diagnose mesothelioma, a patient must first speak to their doctor about the history of asbestos exposure they have suffered and any symptoms they may be experiencing. Doctors can also conduct an examination of the body and order tests to determine the health of the lungs.
X-rays or CT scans can aid doctors in identifying the affected area better. In some cases doctors may use an pleural effusion test in order to determine if mesothelioma or a different disease is causing the accumulation of fluid in the lung. The pleural effusion could be a symptom of pleural mesothelioma, peritoneal mesothelioma or a rarer form of mesothelioma referred to as biphasic or mixed mesothelioma.
The mesothelioma symptoms are often misdiagnosed, as they resemble those of other illnesses. The most common symptoms are chest pain and breathing difficulties. Pleural mesothelioma could also cause fatigue, chest tightness, and a cough. Peritoneal mesothelioma can cause abdominal discomfort swelling, distension and pain. Testicular mesothelioma may manifest as a painful itchy lump on the testicles.
Researchers are studying specific blood-borne proteins in hopes of developing a way to identify mesothelioma earlier in its development. They are also studying various other tests and procedures which could improve the accuracy of diagnosis. These include mesothelioma images and MRIs. They are also researching genetic mutations, and how to determine if a person is at risk for mesothelioma by taking a look at their family background.
Treatment
Asbestos is the primary mesothelioma-related risk factor. People who worked with asbestos in the past, especially for prolonged periods of time or in high risk jobs such as electrical work, shipbuilding, auto repair and military service are at greater risk.
Exposure to asbestos can cause mesothelioma, when fibers are trapped in tissue that lines and protects vital organs. The fibers cause DNA damage and irritation to the mesothelium which leads to the growth of cancerous cells. The symptoms of mesothelioma typically are not evident for a long time after exposure.
The symptoms vary based on the type of mesothelioma and the location it occurs in the body. Most mesothelioma cases involve the lining of the lungs (pleural mesothelioma), but it can also occur in the lining of the stomach (peritoneal mesothelioma) or the heart (pericardial mesothelioma) or testicles (testicular mesothelioma).
Mesothelioma staging helps doctors determine treatment options. The disease is classified as stage I through stage IV, with stages I and II being early and the most manageable. Stage III and stage IV are the last stages of cancer and are more difficult to treat. However, there are still many options for treatment.
Pleural mesothelioma, the most prevalent form of the disease and affects the lung lining and chest wall as well as the abdomen. In the majority of cases of pleural mesothelioma, asbestos exposure happened in the workplace. Most likely asbestos was inhaled via airborne particles or inhaled through food items.
Other risk factors include a genetic mutation in the family, and prior treatment for a different condition. If you've been exposed to asbestos and suffer from mesothelioma symptoms it is essential to consult a doctor. You could also benefit from genetic counseling. A mesothelioma expert can help you in filing a lawsuit against companies that have used asbestos in a wrong way in their everyday products.
