Obtaining accurate residential histories to improve the study of cancer risk
The environment in which one lives can affect the risk of developing cancer. Risks and exposures vary by region and by neighborhood. Epidemiologists concerned with describing the totality of environmental risks might be able to improve estimates by accounting for the risk associated with each place a person has lived: where they lived and how long they lived there. However, improving these estimates requires accurate information on residential histories.
Westat conducted a study for the National Cancer Institute (NCI)/SEER to assess the potential sources of residential addresses and the accuracy of the data they offer.
