UPDATED:Causes

Working with asbestos is the major risk factor for mesothelioma.In the United States, asbestos is the major cause of malignant mesothelioma and has been considered "indisputably" associated with the development of mesothelioma. Indeed, the relationship between asbestos and mesothelioma is so strong that many consider mesothelioma a “signal” or “sentinel” tumor. A history of asbestos exposure exists in most cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos. In rare cases, mesothelioma has also been associated with irradiation, intrapleural thorium dioxide (Thorotrast), and inhalation of other fibrous silicates, such as erionite. Some studies suggest that simian virus 40 (SV40) may act as a cofactor in the development of mesothelioma.

Latency, the time from first exposure to manifestation of disease, is prolonged in the case of mesothelioma. It is virtually never less than fifteen years and peaks at 30–40 years.[6] In a review of occupationally related mesothelioma cases, the median latency was 32 years Based upon the data from Peto et al., the risk of mesothelioma appears to increase to the third or fourth power from first exposure.

Environmental exposures

Incidence of mesothelioma had been found to be higher in populations living near naturally occurring asbestos. For example, in central Cappadocia, Turkey, mesothelioma was causing 50% of all deaths in three small villages — Tuzköy, Karain and Sarıhıdır. 

Occupational

Exposure to asbestos fibers has been recognized as an occupational health hazard since the early 20th century. Numerous epidemiological studies have associated occupational exposure to asbestos with the development of pleural plaques, diffuse pleural thickening, asbestosis, carcinoma of the lung and larynx, gastrointestinal tumors, and diffuse malignant mesothelioma of the pleura and peritoneum

Paraoccupational secondary exposure

Family members and others living with asbestos workers have an increased risk of developing mesothelioma, and possibly other asbestos related diseases.This risk may be the result of exposure to asbestos dust brought home on the clothing and hair of asbestos workers

Asbestos in buildings

Many building materials used in both public and domestic premises prior to the banning of asbestos may contain asbestos. Those performing renovation works or DIY activities may expose themselves to asbestos dust. In the UK use of Chrysotile asbestos was banned at the end of 1999. Brown and blue asbestos was banned in the UK around 1985. Buildings built or renovated prior to these dates may contain asbestos materials.

Mesothelioma Life Expectancy

The life expectancy of a pleural mesothelioma patient depends upon a number of factors. Each patient has a unique case that affects their prognosis and treatment will revolve around their specific needs. A number of studies have revealed that the median life expectancy for mesothelioma cancer patients ranges between four and 18 months. 

Currently there is no cure for pleural mesothelioma cancer, but advancements in mesothelioma treatment are continuing to improve the life expectancies of many patients. A number of pleural mesothelioma survivors are demonstrating that median life expectancies are merely numbers that can be beaten.

Factors Affecting Pleural Mesothelioma Life Expectancy

There are several factors that can affect the life expectancy of a pleural mesothelioma patient, including:

Latency Period – Though many cancers exhibit symptoms relatively quickly, the signs of pleural mesothelioma cancer do not surface until later stages of cancer development and this may be 20 to 50 years after initial exposure to asbestos. Because of the latency of symptoms, the cancer is typically diagnosed during the advanced stages. Those with a history of asbestos exposure should seek annual asbestos screenings to check for signs of disease.

Stage at Diagnosis – Life expectancy is greatly affected by the stage of the cancer at diagnosis. A prognosis can be poor if the cancer is detected in a late stage of development and when treatment options are fewer and less effective. If the cancer is caught earlier, a patient’s prognosis may improve since more treatment options will be available.

Age at Diagnosis – A person’s age at diagnosis can affect prognosis because older patients often experience difficulty when receiving an aggressive treatment approach that tries to cure the cancer. The average age of a mesothelioma patient is 60 and more than 75 percent of mesothelioma cases are diagnosed in men age 55 or older.

Feasible Treatment Options – Depending on the health of the patient and their stage at diagnosis, a pleural mesothelioma patient may be able to withstand aggressive treatments that attempt to cure the disease or they may only be able to handle palliative treatment options (which aim to alleviate symptoms and improve quality of life rather than cure the cancer). In some cases, taking a more aggressive treatment approach can prolong life expectancy, but this varies from patient to patient.

Smoking and General Health – Pleural mesothelioma patients who refrained from smoking and lived a healthy lifestyle prior to their diagnosis tend to have a better prognosis. Patients who smoked or had poor health before diagnosis often exhibit compromised lungs or immune systems, and this can have a negative affect on life expectancy.

Improving Pleural Mesothelioma Life Expectancy

Though some life expectancy factors such as age at diagnosis or latency period cannot be altered or otherwise improved, advancements in pleural mesothelioma treatment are improving life expectancies for many patients. Medical professionals that research and treat pleural mesothelioma are always seeking and testing new methods to improve the prognosis, which is primarily achieved through clinical trials and mesothelioma research. These trials test new medications and treatment options and a number of mesothelioma patients have benefited from participating in such clinical studies.

Advancements in the early diagnosis of pleural mesothelioma are also opening up more treatment options to a greater number of patients. Early detection allows physicians to take a more aggressive treatment track and this can greatly improve life expectancy, but this option is not available to all mesothelioma patients and varies from case to case. Some of the more aggressive treatment options include surgery, chemotherapy and radiation.

Pleural Mesothelioma Survivors

Many patients look to mesothelioma survivors to observe their approach to beating the cancer. One common element seems to unite the fighting factor among mesothelioma survivors, and that is a strong and nourished immune system. Most mesothelioma survivors added alternative and complimentary therapies to their standard treatment and these therapies all worked to improve the immune system and the patient’s well being from a holistic approach.

Mesothelioma Prevention

Mesothelioma is a fatal cancer that affects the lining of the heart, lung, or abdominal cavity. The only known cause for malignant mesothelioma is asbestos fibers, microscopic particles given off by asbestos products. These fibers are tough and resilient, they cannot be seen with the human eye and they can be inhaled or ingested without knowledge. Deteriorating asbestos products in the workplace caused tens of thousands of cases of asbestos related disease over the past fifty years and continues to impact several thousand citizens of the U.S. every year.

The U.S. Occupational Safety and Health Administration has enacted a number of workplace asbestos regulations to aid in mesothelioma prevention. Under workplace asbestos laws the permissible level of exposure is 01. fibers per cubic centimeter for an eight-hour work day and one fiber per cubic centimeter in any thirty minute time frame at a work station. Moreover, employers are required to frequently monitor and regulate the work environment in addition to providing their employees with protective clothing and respiratory equipment, sufficient hygiene facilities, routine medical exams, and training.

The Environmental Protection Agency recommends a number of steps and precautions people can take to help protect themselves against non-occupational asbestos exposure that may lead to mesothelioma. These mesothelioma prevention methods include, but are not limited to:

Regular inspection and monitoring of asbestos-containing products or materials around the home since asbestos was commonly used in the production of roof shingles, insulation, flooring, and more.

Don't attempt to remove any asbestos-containing materials. It is vital that you enlist the help of an asbestos removal professional who is properly trained to handle the material and can ensure safe removal.

Avoid vacuuming, sweeping, drilling, sanding, or scraping any surfaces that may contain asbestos fibers. Once these fibers are airborne, they may be inhaled or ingested greatly increasing the risk of mesothelioma.

Sources of Asbestos Exposure

The primary locations for asbestos products today are older buildings that were constructed prior to 1975 and haven't undergone much remodeling since. Every year tens of thousands of home buyers encounter old asbestos floor tiles or linoleum, roofing, siding or insulation after moving into an older home. Removing those products can be done safely, but recognizing them for what they are is critical. Take a sample of whatever old product it is that you intend to remove and ask a professional in the home improvement business what it's made of. When asbestos products get old and crumble they give off fibers that can float in a dust cloud. Old adhesives for flooring and joint compound for walls often contained asbestos, so don't sand them if you don't know what they are.

OSHA estimates that 1.3 million workers in construction and general industry still face significant asbestos exposure on the job today. For construction workers it is usually removing old material on a remodel job or demolishing an old building. Much of the exposure concern for industrial workers has to do with auto repair and older industrial structures. While the dangers are greatly diminished compared to thirty years ago, they are still present for hundreds of thousands of American workers.
