Mesothelioma and Other asbestos case Related Cancers

People who have had a history of exposure to asbestos are at risk for several types of cancer such as mesothelioma. These cancers have a latency time of several decades, which means symptoms may not appear until decades after exposure.

The risk of pleural or peritoneal msothelioma decreases with time after first exposure. Evidence is based on six occupational and two residential cohort studies that have a long-term follow-up.

What is Mesothelioma?

Mesothelioma is a cancer of the inner organs' linings that include the lungs (pleural mesothelioma) and abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It is a rare, dangerous disease that typically starts within the lining of the chest cavity. However, it could also affect the lining in 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 exposed to asbestos at work have a higher risk of developing the disease than other. Asbestos fibers can be inhaled or swallowed and cling to the organ's lining. They irritate the lining of the organs, causing abnormal cells to grow and forming tumors. The symptoms usually don't manifest until the person has advanced mesothelioma.

Most asbestos exposure occurs in industrial settings where workers are exposed to the material or work near it. Asbestos is used in many trades, such as construction, shipbuilding and auto repair. Veterans who were in the military are at greater risk of mesothelioma because asbestos was widely used on ships and bases.

People who have a exposure to asbestos need to have regular checkups, and should be alert for any unusual symptoms. If a doctor suspects mesothelioma, they may request imaging scans such as CT scans or MRI scans to detect tumors and determine if they've grown. They may also perform physical examinations and inquire about the patient's asbestos exposure background. Certain cases of mesothelioma may be linked to genetic changes. Thus, certain patients could benefit from genetic tests.

Risk Factors

Asbestos exposure is the main mesothelioma-related risk factor. Asbestos is a mineral that is made by tiny fibers which are strong and withstand heat. Asbestos is used in many construction and manufacturing products including insulation, brakes and shingles. When asbestos is disturbed it creates dust that may be swallowed or inhaled. As time passes, this could cause irritation of the mesothelium, which can ultimately develop into mesothelioma.

Mesothelioma is most common in people who have an occupational history of exposure to asbestos. This includes people who worked in industries like shipbuilding, mining, construction and automotive repair. Veterans of the military are also at risk since many branches of the military utilized asbestos-based materials.

Other factors that increase the risk of mesothelioma is an asbestos-related family history exposure and previous radiation therapy to the chest. The type of mesothelioma diagnosed also has a major impact on the risk. Pleural mesothelioma, the most prevalent form and typically affects the lungs. Other forms of mesothelioma include peritoneal (pericardial), testicular, and the peritoneal.

The risk of mesothelioma generally increases with the third or fourth power of latency which is the length of time it takes to diagnose someone. However, the incidence of pleural mesothelioma has a slight flattening out after about 40 years after exposure. Peritoneal and pericardial mesothelioma have the same trend. Exposure to asbestos case that is not occupational like living near an asbestos plant or eating contaminated household products, can also increase the risk of mesothelioma. In the study of six cities in the United States, those who were exposed to asbestos in this manner were at a higher risk of mesothelioma compared to those who had only occupational exposure.

Signs and symptoms

The inner organs' linings are affected by mesothelioma that is malignant. It is most often found in the linings of the lungs and abdomen. Mesothelioma can also develop in the lining around the testicles or the heart. It is a rare form of cancer and most people diagnosed with mesothelioma worked in positions that exposed them to asbestos. It can take decades for mesothelioma-related symptoms to manifest, and the disease is not curable.

Asbestos is a group of minerals with tiny microscopically-sized fibers that resist heat, fire, and chemicals. It is extensively employed in a variety of industries, such as shipbuilding, construction, manufacturing and more. Exposure to asbestos can lead to mesothelioma because the fibers get stuck in the tissues that line and protect organs, causing irritation and damaging cells. This can cause tumors to start growing and eventually becoming cancerous.

The most common form of mesothelioma occurs in the wall (pleura) of the lungs. It can also begin in the lining around the testicles or the heart, or in the abdomen's lining (peritoneum). Mesothelioma may also expand to lymph nodes and cause them to expand.

The majority of people diagnosed with mesothelioma are those who have an extensive history of exposure to asbestos and are already suffering from other diseases like chronic lung disease. Mesothelioma symptoms may be similar to other diseases, so you should consult a doctor when any recurring or alarming symptoms persist. Doctors will inquire about your asbestos exposure in the past and may conduct an examination. They can also order scans of your body or blood tests of your chest and abdomen. These tests can detect any signs of thickening or fluid between the lungs and the chest wall.

Diagnosis

Asbestos fibers that get stuck on the body can cause damage, and eventually develop into cancerous tumors. Asbestos-related cancers can develop in different organs or tissues. Each type of cancer can be diagnosed with a different test. Mesothelioma can be found in the linings of the chest cavity, lungs, stomach (peritoneum), or around the reproductive organs, such as the heart or reproductive system.

The first step to diagnose mesothelioma is to talk with their doctor about their history of asbestos exposure and the symptoms they've been experiencing. Doctors also conduct a physical examination and may order tests of a basic nature like blood tests to determine how well the lungs are working.

X-rays or CT scans can help doctors see the affected area better. In some cases doctors will perform a pleural effusion test to determine if mesothelioma, or another disease is causing fluid accumulation in the lung. Pleural effusions may be an indication of pleural, mixed or peritoneal mesothelioma.

Mesothelioma is often misdiagnosed because the symptoms resemble other diseases and conditions. The most commonly reported symptoms are breathing difficulties and chest pain. Pleural mesothelioma can cause chest tightness, fatigue, and a cough. Peritoneal mesothelioma can lead to abdominal pain, swelling and distension. Testicular mesothelioma may manifest as a painful or itchy lump in the testicles.

Researchers are studying the proteins in blood to create a way of identifying mesothelioma in the early stages. They are also looking into various other tests and procedures that can enhance the accuracy of diagnostic tests, including mesothelioma imaging and MRIs. They are also researching genetic mutations, and how to determine if a person has a mesothelioma-related risk by taking a look at their family history.

Treatment

Asbestos is the most significant risk factor for mesothelioma. People who have worked with asbestos, particularly in high-risk occupations such as electrical work, construction or auto repair, shipbuilding and military service are at risk.

Exposure to asbestos can trigger mesothelioma. The fibers get stuck in the tissue that connects vital organs and protects them. The fibers cause irritation to the mesothelium and cause DNA damage that leads to cancerous cells. Mesothelioma symptoms generally don't manifest until decades after exposure.

The symptoms of mesothelioma can vary according to the type and where it is located in the body. The majority of mesothelioma patients have a lining in their lungs (pleural) however it may also affect the stomach's lining and testicles, as well as the heart.

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 treatment-able. Stage III and stage IV are the more advanced stages of cancer, and are more difficult to treat. However there are many options to treat.

The most common mesothelioma form affects the lung linings, as well as the chest wall and the abdomen. In most cases of pleural mesothelioma, asbestos exposure occurred in the workplace. It was most likely due to breathing in airborne asbestos particles or ingesting the cancerous substance through the food chain.

Other risk factors include mesothelioma in the family, genetic mutations and previous radiation therapy for another condition. It is important to consult a doctor if you have symptoms of mesothelioma and have been exposed to asbestos. Genetic counseling may also be beneficial. In some cases mesothelioma experts can help you file a lawsuit against companies that have knowingly used asbestos in their everyday products.
