Mesothelioma Causes Other Than Asbestos

The tissue that surrounds the lungs and other organs can develop mesothelioma. Patients who develop this cancer usually worked on jobs which exposed them to asbestos.

Asbestos is one of the minerals that form strong microscopically-sized fibers. It was used to create automobile and construction materials as it is invulnerable to fire, heat and water.

Workplace Exposure

Asbestos is a natural mineral that was extensively used to protect against fire before it was banned in the 1970s. Workers who handled asbestos whether they mined it or handled it in factories are at risk of developing mesothelioma. The highest risk is for those who have been exposed to large amounts of tiny asbestos fibers over a long time. Mesothelioma is usually not diagnosed until decades after exposure to asbestos. For this reason, the majority of mesothelioma cases are linked to exposure to asbestos in the workplace.

When asbestos is disturbed, its tiny fibers become airborne and can be inhaled or swallowed. These fibers may get into the thin layer of tissue surrounding organs. This layer, dubbed the mesothelium, can develop mesothelioma-like cancerous tumors. Pleural mesothelioma is a tumor that develops around the lung and is the most frequent mesothelioma form. Other mesothelioma types include mesothelioma that develops in the abdomen and pericardial mesothelioma growing around the heart.

It can also occur in other areas of your body, if you inhale asbestos or ingest it in smaller amounts. It can also develop in the testicles' linings and the abdominal cavity. Mesothelioma is typically the result of mesothelium damage and it's difficult to determine if it was caused by occupational exposure or some other cause.

Certain people who have mesothelioma develop the disease from secondhand contact. Take-home exposure occurs when asbestos is taken home by workers on their clothing or equipment. In these cases families usually clean and wash the clothes of workers which can lead to greater risk of exposure than would normally be expected. Certain studies have revealed that the use of an asbestos-like material called erionite can increase the risk of mesothelioma in those living near erionite deposits.

Other factors that may increase the risk of mesothelioma is certain medical treatments, like chemotherapy and radiation. These treatments can damage mesothelium, causing mesothelioma. However they don't make up a large percentage of cases.

Secondhand Exposure

Other factors can increase a person's risk of developing mesothelioma. This includes genetics, history of radiation therapy for the chest area and exposure through secondhand sources. A family history of the disease can increase the risk for an individual. However, asbestos is the most common cause of mesothelioma.

People who work directly with asbestos have the highest risk of developing mesothelioma. This is especially true for those who are employed in the construction, manufacturing, shipbuilding and asbestos mining industries. People who work with asbestos often inhale tiny asbestos fibers when they tear or damage the material. The fibers then end up within the lining of the lungs, the heart and stomach. The asbestos can remain in the body for a long period of time, causing malignant mesothelioma tumors to develop.

Inhaling or swallowing these contaminated fibers can lead to mesothelioma pleural, peritoneal mesot and other types of the disease. The symptoms can manifest anywhere between 30 and 50 years after exposure. To determine if mesothelioma is a disease, the doctor must first rule out any other conditions that could cause symptoms.

Pleural mesothelioma is the most commonly encountered form of this cancer. After asbestos exposure the chance of developing this form of mesothelioma is believed to decrease. However, the risk of peritoneal mesothelioma continues to rise even after the asbestos exposure has ended.

Asbestos is a class of six naturally occurring metamorphic fibrous minerals. It is extremely durable and resistant to heat and fire, making it a popular option for military, industrial and commercial applications throughout the 20th century. Asbestos was widely used from the end of World War II and the mid-1970s. It was often found in ships, insulation and buildings, as well as automobile components.

Workers who used to handle asbestos, or inhale it, were the most likely group to have developed mesothelioma. However, some people have been diagnosed with mesothelioma but have no occupational history of exposure to the mineral. They were exposed by other means. Women who had husbands working with asbestos brought home asbestos fibers from their skin or clothing. The asbestos contamination that was present in the Polio vaccine in the 1950s and 1960s has been proven to increase the risk of mesothelioma for those who were vaccinated.

Environmental Exposure

Asbestos is the primary reason for mesothelioma. However other factors could be involved. This could be due to the person's gender, age, or genetics. People who have a predisposition to mesothelioma, or other health problems are at higher risk than those without.

Exposure to asbestos case in the workplace is responsible for the majority of mesothelioma cases. The greatest risk is for those who have been exposed to asbestos over an extended period of time, such as mine workers or shipyard workers. However, a lot of people who have mesothelioma have not directly worked with asbestos. Secondhand exposure can also occur when someone lives with a person who worked with asbestos and breathed asbestos litigation-based fibers. This kind of exposure is usually in the spouses of asbestos workers.

The symptoms of mesothelioma may become more apparent over time, and they may differ depending on the type of cancer a person is. Everyone should be aware of the risks they face and speak to their doctor if any symptoms are unusual or alarming.

Asbestos exposure may cause three types mesothelioma - abdominal, pleural and the pericardial. The lung is affected by pleural mesothelioma while organs in the abdominal cavity are affected by peritoneal as well as the pericardial. The majority of mesothelioma develops in the lungs. However, peritoneal mesothelioma could be found in the abdominal cavity. mesothelioma that is pericardial develops in the lining surrounding the heart.

Researchers have discovered that different substances may cause mesothelioma too. Radiation therapy and erionite (a mineral similar in appearance to asbestos litigation) are among the substances that can cause mesothelioma. A virus known as SV40 and certain kinds of talcum powder may also cause mesothelioma.

The research into the causes of mesothelioma may aid doctors in diagnosing the cause more accurately and speedily. Patients with mesothelioma can receive treatment earlier and better their outcomes. It is also essential to know the mesothelioma risks of other factors so we can help prevent more mesothelioma cases in the near future. For example the use of talcum powder could lead to more women developing mesothelioma of the peritoneal region. By educating people about mesothelioma, we can decrease the number of people diagnosed with the cancer. This is important since mesothelioma can have symptoms that may be delayed by up to 50 years.

Genetics

If you've been diagnosed with mesothelioma, you should consult a specialist. Early treatment offers the best chance for a positive outcome. The research continues to uncover other risk factors, such as talcum and SV40. Knowing and avoiding these risk factors will help to prevent the occurrence of more cases of mesothelioma.

Asbestos is an asbestos-related group of mineral fibers with fibrous structure which was extensively used throughout the 20th century for commercial, industrial and even military applications. Its strength and resistance to fire led to it being a favorite among manufacturers. Researchers documented the dangers and made it clear that asbestos was dangerous. Its phase-out followed. People who have been exposed to asbestos legal (visit this page) while at work are at the greatest risk for mesothelioma. This includes miner factory workers, miner's workers and asbestos insulation installers. They also include shipbuilders, railroad employees automakers, railroad workers.

Inhaling asbestos fibers are deposited in the lining of the lungs (the pleura), where they become irritated and eventually develop tumors. The symptoms of mesothelioma may take years to show up, however they are typically advanced by the time that they appear. Symptoms can include chest pain, heaviness or difficulty breathing. Fluid accumulation in the lungs can be a symptom.

Mesothelioma is caused by cancerous mutations of cells. Researchers believe that exposure to asbestos is the main cause, but they believe that genes play an important role. Researchers discovered a gene known as BAP 1, which is located on the short arm chromosome 3, that causes mesothelioma. They discovered this gene after studying epidemics of mesothelioma in two U.S. families with Swiss ancestry. The mutation in the gene was discovered in every member of the family suffering from mesothelioma.

Genetics is only one aspect of the mesothelioma enigma however it is a significant one. A small percentage of asbestos-related sufferers develop mesothelioma. This suggests that genes play a role. The majority of patients with mesothelioma have mutations in their tumor suppressing genes. As the research advances these genes will be investigated and better understood to stop mesothelioma from developing. It is possible that those who are genetically predisposed to mesothelioma may also need to be more cautious about asbestos exposure, and will require regular screening for symptoms.
