The time trends in incidence and mortality from cervical cancer and breast cancer in Iceland, from 1955 to 1989, were analyzed by fitting curvilinear regressions to the age-standardized rates. The effect of the screening was evaluated by comparing the curvature of the fitted regression lines and changes in screening activity. The incidence and mortality rates for both cancer types were predicted up to the year 2000. At the commencement of cervical cancer screening in 1964, both the incidence and mortality rates were on the increase. After 1970, both rates decreased significantly. Assuming that regular attendance at screening will be 85
