Buzz Index. The American Cancer Society's estimates of cancer incidence and mortality were used. News reports associated with specific cancer types were identified using the LexisNexis ``US News'' database, which includes more than 400 national and regional newspapers and a variety of newswire services. Results: The Yahoo! search activity associated with specific cancers correlated with their estimated incidence (Spearman rank correlation, $\rho$ = 0.50, P = .015), estimated mortality ($\rho$ = 0.66, P = .001), and volume of related news coverage ($\rho$ = 0.88, P < .001). Yahoo! cancer search activity tended to be higher on weekdays and during national cancer awareness months but lower during summer months; cancer news coverage also tended to follow these trends. Sharp increases in Yahoo! search activity scores from one day to the next appeared to be associated with increases in relevant news coverage. Conclusions: Media coverage appears to play a powerful role in prompting online searches for cancer information. Internet search activity offers an innovative tool for passive surveillance of health information--seeking behavior.
