The benefits of big data in healthcare have already been proven around the world. In fact, the collection and analysis of data is the fastest growing trend in healthcare. Data collected from across multiple organizations within a population can be used to study trends and develop strategies geared toward the most effective treatment and prevention of disease. With this in mind, the California Department of Public Health created the California Cancer Registry (CCR) to gather data and analyze the various factors affecting cancer risk. The California State Assembly then passed a law requiring Pathologists to report all cancer diagnoses to the CCR using the College of American Pathologists' protocols. The law goes into effect Jan 1, 2019.
