Mesothelioma and Other Asbestos Related Cancers

People with an exposure history to asbestos are at risk for several types of cancer such as mesothelioma. These cancers have a latency time of many years, meaning that symptoms may not be evident until decades after exposure.

The risk of developing pleural or peritoneal mesothelioma declines with time from the first exposure. The evidence is based on six occupational cohort studies and two residential cohorts with long-term following.

What is Mesothelioma?

Mesothelioma is cancer of the inner organs' linings that include the lungs (pleural mesothelioma) and abdomen (peritoneal mesothelioma) or heart (pericardial mesothelioma). It's a rare, aggressive disease that typically begins in the chest's lining cavity, but it may also be found in the lining of the stomach or in other areas of the body. Asbestos exposure is the most common cause of mesothelioma, and the cancer is usually not able to appear until decades after the initial exposure.

People exposed to asbestos while at work are at an increased risk of developing the disease than other. Asbestos fibers can be inhaled or swallowed and cling to the lining of organs. The fibers cause irritation to the lining of the organ and cause abnormal cells to multiply, leading to tumors. The signs usually don't show until someone has advanced mesothelioma.

Most asbestos exposure occurs in the workplace in which workers handle the substance or work around it. asbestos attorney is used in many trades, including construction, shipbuilding and auto repair. Veterans who served in the military are at particular risk for mesothelioma, as asbestos lawyer was extensively used on ships and bases.

People with an history of exposure to asbestos should be screened regularly and be aware of any unusual symptoms. If the doctor suspects mesothelioma they could order imaging tests like CT scans, MRI or PET scans to look for the tumors and see whether they've expanded. They may also perform an examination and inquire about a patient's asbestos exposure history. Some cases of mesothelioma are related to genetic changes, and therefore some patients might benefit from genetic testing.

Risk Factors

The most significant risk factor for mesothelioma is exposure to asbestos. Asbestos is a substance made by tiny fibers which are durable and resistant to heat. Asbestos was used in many construction and manufacturing products including insulation, brakes, and shingles. Asbestos dust is inhaled and swallowed if disturbed. In time, this may lead to irritation of the mesothelium, which may eventually develop into mesothelioma.

People who have an history of occupational asbestos litigation exposure are at the most risk of mesothelioma. This includes those who have worked in industries such as mining, shipbuilding and construction as well as in auto repair. Veterans of the military are also at risk since many branches of service employed asbestos-based materials.

Other factors that increase the risk of mesothelioma is a family history of asbestos exposure and previous radiation therapy to the chest. In addition the type of mesothelioma that is diagnosed has a significant impact on the risk. Pleural mesothelioma is the most common form and typically affects the lung. Other forms of mesothelioma are testicular, pericardial and peritoneal.

In general, the risk of mesothelioma increases with the third to fourth power of latency - which is the time it takes a person to be diagnosed. However, the rate of pleural mesothelioma shows a slight flattening out after approximately 40 years of exposure. Peritoneal and pericardial mesothelioma both have this pattern as well. Individuals who have exposure to asbestos, like living near to an asbestos plant or eating products that contain asbestos - are also at increased risk of developing mesothelioma. A study of six cities revealed that those who had this type of exposure had a higher mesothelioma risk than those who had only occupational exposure.

Symptoms

Malignant mesothelioma affects the cellular of the organs' linings. Most commonly, it occurs in the lung linings and the abdomen. Mesothelioma can also occur in the lining of the heart or testicles. It is a rare cancer and the majority of people diagnosed with mesothelioma worked on jobs that involved exposure to asbestos. It could take years for symptoms of mesothelioma to develop and the disease is not curable.

Asbestos is an assortment of minerals that possess tiny fibers that are resistant to heat, chemicals, and fire. It is widely employed in a variety of industries, such as shipbuilding, manufacturing, construction, and more. Exposure to asbestos can lead to mesothelioma due to the fibers getting stuck in the tissues that line organs and protect them that cause irritation and damage to cells. This can cause tumors to expand and eventually become cancerous.

The most commonly encountered type of mesothelioma is pleural mesothelioma, which develops in the lining of the lungs (pleura). It can also start in the lining of the abdomen (peritoneum) or in the membrane that surrounds the testicles or the heart. Mesothelioma can also spread to lymph nodes, which causes them to expand.

Most people who are diagnosed with mesothelioma had a long history of exposure to asbestos and are already suffering from other diseases like chronic lung diseases. Symptoms of mesothelioma can be similar to other conditions and it is therefore important to consult a doctor when you observe any persistent or worrying signs and symptoms. Doctors can inquire about asbestos exposure in the past and perform an examination. They may also order scans and blood tests of your abdomen or chest. These can identify any swelling of the lung's lining or fluid in the space between your lungs and the chest wall.

Diagnosis

Asbestos fibers that become stuck on the body can cause harm and may eventually grow into cancerous tumours. Asbestos-related tumors can grow in a variety of organs and tissues. Each type of cancer can be diagnosed with a different test. Mesothelioma forms in the lining of the chest cavity and the lungs (pleura), the stomach membranes (peritoneum) or around the reproductive organs and the heart.

The first step in identifying mesothelioma is for a patient to talk with his or her doctor about their history with asbestos exposure and what symptoms they have been experiencing. Doctors will also conduct an examination of the body and order tests to assess the health of the lung.

X-rays and CT scans help doctors get a clearer picture of the affected area. In some cases doctors will perform the pleural effusion test to determine if mesothelioma or another disease is causing fluid buildup in the lung. The pleural effusion could be a symptom of pleural mesothelioma, peritoneal mesothelioma or a rarer type of mesothelioma called biphasic 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 difficulty breathing and chest pain. Pleural mesothelioma can also cause chest tightness, cough and fatigue. Peritoneal mesothelioma can cause abdominal pain, swelling and distension. Testicular mesothelioma may manifest as a swollen or itchy lump in the testicles.

Researchers are studying certain blood-borne proteins in the hope of figuring out methods to detect mesothelioma earlier in its development. They are also looking into a number of other tests and procedures that may enhance the accuracy of diagnostic tests, including mesothelioma imaging as well as MRIs. They are also researching genetic mutations and ways to determine whether a person is at risk of developing mesothelioma through analyzing their family history.

Treatment

Asbestos exposure is a major risk factor for mesothelioma. People who have worked with asbestos, especially in high-risk occupations like electrical work, construction or auto repair, shipbuilding and military service are at an increased risk.

Exposure to asbestos triggers mesothelioma as fibers become stuck in the tissue that lines and protects vital organs. The fibers cause DNA damage and irritation to the mesothelium which leads to cancerous cell growth. Mesothelioma symptoms generally do not appear until decades after exposure.

The symptoms differ based on the type of mesothelioma and the location it develops within the body. Most mesothelioma cases involve the lining of the lungs (pleural mesothelioma) however it may also be found in the stomach's lining (peritoneal mesothelioma), heart (pericardial mesothelioma) or testicles (testicular mesothelioma).

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

Pleural mesothelioma is by far the most common form of the disease that affects the lung lining and chest wall, as well as the abdomen. In most cases of pleural mesothelioma, asbestos exposure was a result of the workplace. This is most likely because of exposure to asbestos particles in the air or ingesting the cancerous substance through the food chain.

Other risk factors include a family history of mesothelioma, genetic mutations, and prior radiation therapy for another condition. If you've been exposed to asbestos and suffer from mesothelioma symptoms, it is crucial to see an expert. You may also benefit from genetic counseling. In some cases, a mesothelioma specialist can assist you in filing a lawsuit against companies that wrongfully put asbestos in everyday products.
