Varying Latency Periods

A number of studies have been conducted on the specifics of the length of latency periods among those exposed to asbestos.
In the case of mesothelioma, evidence has indicated that high exposure for short periods of time might be more damaging than low exposure for many years. For example, Deborah Reeve, a New York City paramedic and first responder at the site of the World Trade Center attacks in 2001, passed away from mesothelioma in 2006, just five years after her exposure to asbestos from the events on September 11. Deborah had symptoms of the disease as early as 2003 and was diagnosed with mesothelioma in 2004.
Numerous studies on asbestosis agree that more than 90 percent of individuals who were exposed to asbestos for 40 years or more will develop the disease. For those who worked with the toxic mineral for 20-30 years, the rate is about 75 percent. Those who experienced 10-19 years of exposure have an incidence level of about 10 to 15 percent. These numbers may also vary according to the level of asbestos someone is exposed to on a daily basis.
For example, shipbuilders of the mid-20th century were nearly always surrounded by asbestos as were many construction workers. Those groups have tended to develop asbestosis sooner than those who worked in other industries where the levels may not have been as high.
Patients concerned about the latency period associated with mesothelioma and the possibility of developing the cancer may be interested to read more about mesothelioma symptoms.
