Latency period of mesothelioma

The period between that person has been exposed to asbestos develop mesothelioma until called latency period.Although there are various diseases associated with asbestos, mesothelioma is the latency period has increased. Typically spend 35 to 40 years between exposure and diagnosis, although there are cases that are diagnosed after just 20 years old and up to 50 years after exposure.
As a general rule, the greater has been the least exposure is the latency period. The average age of a patient diagnosed with malignant pleural mesothelioma is between 40 and 69 years. When the patient is under 40, it is usually because it has been a childhood exposure. In children mesothelioma is so rare that doctors always relate to an environmental exposure.

Additional Considerations

The long latency period of mesothelioma is a factor in the poor prognosis associated with this disease contributes significantly. As with all forms of cancer, the sooner they diagnose mesothelioma greater the chances of treatment. Unfortunately, as ovarian cancer or lung cancer, mesothelioma symptoms usually go unnoticed until the last stages.
Mesothelioma can initially manifest in various parts of the body. One study found that in 69 patients mesothelioma in the chest area had a latency period of 35 years of dormancy, while mesothelioma in the abdomen had a latency of 28 years. Although the exposure times may vary, the mean duration of exposure associated with peritoneal mesothelioma is 11 years, while exposure associated with pleural mesothelioma is only five years.

Timeframe

Most cases of mesothelioma are a direct result of occupational exposure. This exhibition is currently regulated in most of the developed world, but because of the long latency period of new vessels will be diagnosed until at least 2020. Statistics on the diagnosis recorded its peak about 30 to 40 years since asbestos was used.

Substitution statistics

The pattern of change statistics for the next 20 years due to the fact that life expectancy is substantially higher than several decades ago. Many people died even before the disease developed. However in 2007 the life expectancy for retirees at age 65 years and 19.9 years for women and 17.2 in the case of men was set. Besides the regulation of asbestos has caused the number of exposures is reduced. Therefore it is expected to be an increase in the latency period.
However, there have been recent events have shown that there may be an exception to this trend. In the fatal attack of September 2,011 to Word Trade Center, much of the first that helped and New York residents were exposed to asbestos fibers that hung in the air as a result of the demolition of neighboring buildings. A doctor named Deborah Reeve helped in recovery but started having breathing problems after two years. She was soon diagnosed with mesothelioma and died in March 2006. Periods as brief as this latency are extremely rare but can occur.

Secondary exposure

Before the use of asbestos, families and wives of those who worked with this material were regularly exposed to its fibers as these were carried home on work clothes. Any member of the family could be in contact with clothing or hair of a person who may have been exposed to asbestos while working.
The exposure time frame may be difficult to draw because of the long latency period. `A person may have been briefly exposed to asbestos while working a few weeks this summer on construction of a building. That brief exposure to asbestos can be enough for many years after developing mesothelioma, without the person may be able to remember that brief exposure in their youth. This causes the latency period statistics are a challenge, but stop working researchers seeking new treatments or even a cure.
