Analisi rischio-beneficio in mammografia: Uno studio sulla popolazione dell'Umbria %XA risk analysis for mammographic screening has been carried out in Umbria with reference both to the general population and to a more restricted one which was selected on the basis of physical examination results and common risk-factors. Losses of life-expectancy for screened and unscreened subjects have been compared. Leaving out of account economic and social factors, data analysis seems to indicate that for the selected population a one-year periodicity mammographic screening is a proper one if starting at age 31. Concerning the general population, maximum benefit is obtained for a one-year periodicity screening starting at older ages, which depend both on the hypothesized dose (with or without screens) and on the assumed tumor doubling time. %0Technical Report %NISS-R-84/4;Other: ON: DE87900294 %1 %CItaly %Rhttps://doi.org/ Other: ON: DE87900294 TIC %GItalian
