Mesothelioma Causes Other Than Asbestos

Mesothelioma can be found in the tissue that lines the chest wall, lungs, abdomen and other organs. Patients who develop this cancer usually had jobs that exposed them to asbestos.

Asbestos is one of the minerals that make strong, microscopic fibers. It was used in the construction and automotive industries because it resists heat, fire, and water.

Workplace Exposure

Asbestos is a natural mineral that was used extensively for its fireproof properties prior to when it was banned in the 1970s. Workers who handled asbestos, whether they mined it or worked with it in factories are at risk of developing mesothelioma. Those who have the highest risk are those who were exposed to large amounts of microscopic asbestos fibers for extended periods of time. Mesothelioma symptoms typically don't appear until decades after exposure to asbestos. For this reason, the majority of mesothelioma cases are attributed to occupational asbestos exposure.

When asbestos is disturbed, its tiny fibers can become airborne and can be breathed in or swallowed. These fibers can be transported to the thin layer of tissue that surrounds organs. This layer, called the mesothelium can grow into mesothelioma-like cancerous tumors. The most popular mesothelioma type is mesothelioma pleural that develops around the lung. Other mesothelioma types include peritoneal mesothelioma, forming in the abdomen, and pericardial mesothelioma, developing around the heart.

Mesothelioma may also form in other areas of the body when asbestos is inhaled or ingested less frequently. It can develop in the linings of the testicles and abdominal cavity. It's difficult to determine if mesothelioma resulted from occupational exposure or some other cause.

Some individuals with mesothelioma have developed the disease through contact with asbestos lawsuit from the outside. This is often called take-home exposure, and occurs when asbestos is ingested on the clothing of workers or equipment. In these instances workers' clothing is typically cleaned and washed by families, which results in a greater exposure than expected. Some studies have found that the use of a similar asbestos known as erionite increases the risk of mesothelioma in those who live near deposits of erionite.

Radiation and chemotherapy are also medical treatments that may increase your likelihood of developing mesothelioma. These treatments can cause damage to the mesothelium and cause mesothelioma. However, they do not make up a large percentage of cases.

Secondhand Exposure

Many other factors can increase the risk of developing mesothelioma. Genetics, history of radiation therapy to the chest, and secondhand exposure are all factors that can increase the risk of developing mesothelioma. A family history of mesothelioma can also increase the chance of contracting the disease. However, asbestos remains the most common cause of mesothelioma.

Workers who are directly exposed to asbestos have the highest chance of developing mesothelioma. This is particularly true for those who work in construction, manufacturing, shipbuilding, asbestos mining and other related industries. People who work with asbestos often breathe in tiny asbestos law fibers when they break or disturb the substance. The asbestos fibers can end up within the lining of the lungs, stomach and heart. The asbestos could remain in the body for a long period of time, causing malignant mesothelioma tumors to grow.

Inhaling and swallowing these fibers can result in peritoneal, pleural or other mesothelioma types. The symptoms can take anywhere from 30 to 50 years to appear. To diagnose mesothelioma the doctor must first rule out any other medical conditions that could cause symptoms.

Exposure to asbestos is known to cause pleural mesothelioma the most common type of this cancer. It is believed that the risk for mesothelioma that is this type decreases after a person's asbestos exposure ends. However, the risk of mesothelioma of the peritoneal region continues to increase even after exposure to asbestos has ended.

Asbestos is a class of naturally occurring metamorphic fibrous minerals. It is highly durable and is resistant to heat and fire, making it a popular choice for industrial, military and commercial applications throughout the 20th century. Asbestos was heavily used from the end of World War II through to the mid 1970s. It was most commonly found in ship, buildings, automobile parts and insulation.

Workers who handled or inhale asbestos were the most likely group to have developed mesothelioma. However, there are some who have been diagnosed with mesothelioma who have no previous occupational exposure to asbestos. These people were exposed to asbestos through other means. For example, many women who had husbands who employed asbestos brought home asbestos fibers that landed on their clothing and skin. Those who were exposed to the polio vaccine during the 1950s and 1960s have been found to be at a higher risk for mesothelioma as well, due to the contamination of the vaccine for polio with asbestos.

Environmental Exposure

While asbestos is the primary mesothelioma cause but there are a variety of other factors that can also play a role. This may include the person's gender, age, or genetics. People with a genetic predisposition to mesothelioma or other health issues are at a higher risk than those without.

Exposure to asbestos in the workplace is responsible for the majority of mesothelioma cases. People who have a long-term, continuous exposure to asbestos, like shipyard or miners workers, are at highest risk. However, many people with mesothelioma did not work directly with asbestos. The risk of exposure to asbestos can be exacerbated when someone lives with someone who worked with asbestos and breathe in asbestos fibers. This kind of exposure is most common for spouses of workers who worked with asbestos.

Mesothelioma symptoms typically appear over time and differ depending on the type of mesothelioma patient has. It is important for everyone to be aware of their risks and talk to a doctor if they are experiencing any unusual or concerning symptoms.

Asbestos exposure can cause three types of mesothelioma: pleural, peritoneal and pericardial. The lungs are affected by pleural mesothelioma and organs in the abdominal cavity are affected by peritoneal as well as the pericardial. Most mesothelioma forms in the lung. However, peritoneal mesothelioma can develop in the abdominal cavity and mesothelioma pericardial forms in the lining surrounding the heart.

Researchers have discovered that different substances can cause mesothelioma too. This includes erionite, which is a mineral similar to asbestos, and radiation therapy. A virus called SV40 and certain varieties of talcum powder could cause mesothelioma.

The study of the causes of mesothelioma could help doctors identify the cause more precisely and quickly. This allows patients with mesothelioma to receive treatment earlier and improve their outcomes. Knowing the other mesothelioma risk factors is essential to avoid future mesothelioma. For example the use of talcum powder could lead to more women developing peritoneal mesothelioma. By educating the public on mesothelioma we can cut down the number of patients diagnosed with the cancer. This is especially important since mesothelioma symptoms are typically delayed for up to 50 years.

Genetics

If you've been diagnosed with mesothelioma, you should consult a specialist. Early treatment provides the best prognosis. While asbestos exposure is the most common mesothelioma cause but research continues to discover other risk factors such as talcum powder and SV40. Understanding these risks and avoiding them will help prevent the development of more mesothelioma cases.

Asbestos is a class of fibrous minerals that were utilized extensively throughout the 20th century in various industrial, commercial and military applications. Its durability and fire resistance was a major draw for manufacturers. However, the dangers of asbestos were discovered and documented by researchers, resulting in its elimination. People who have been exposed to asbestos while at work are at the highest risk for mesothelioma. This includes miners, factory workers, asbestos case insulation manufacturers and railroad workers, installers, auto makers, ship builders and others who handled or wore clothing contaminated with asbestos.

Inhaled asbestos fibers settle in the lung's lining (the pleura) which is where they get inflamed and then develop into tumors. The symptoms typically take years to appear however, by the time they do mesothelioma is already in advanced. It can be a sign of chest pain, heavy breathing or difficulty breathing. Fluid buildup in the lungs can also be a sign.

Mesothelioma is caused by cancerous cell mutations. These are due to asbestos exposure, but many researchers believe that the genes of a person are also a major factor. Researchers have discovered a gene known as BAP 1 on the short arm of chromosome three that leads to mesothelioma after studying mesothelioma epidemics in two U.S. families with Swiss origins. Every person in the family who developed mesothelioma carried this mutated gene.

Genetics is just one part of the mesothelioma puzzle, but it's an important one. Only a tiny percentage of people who experience asbestos exposure develop mesothelioma which suggests a person's genetics are also at play. Most mesothelioma patients have mutated tumor suppressing genes. As the research continues the genes will be investigated and analyzed more thoroughly to stop more mesothelioma from occurring. It is also likely that those who are genetically predisposed will require greater caution about asbestos exposure and will require regular screening for mesothelioma signs.
