There is a latency period between the time of exposure to asbestos and the manifestation of asbestos diseases that generally varies between several years and several decades.
Many asbestos cancers will not arise in a victim until twenty years or more after first exposure to asbestos. Typically, asbestosis or (pleural plaques) will not occur until at least ten to twenty years after first exposure.
The degree of exposure that a person sustains, impacts the time it takes to show symptoms. A persons individual susceptibility also impacts this.
