    Several recent studies have added significant information regarding the benefit of screening mammography, especially in the 40-49-years age group.

    This new information makes it important to reassess the cost-effectiveness of screening.


    A Markov model was used to study the cost-effectiveness of 4 age-related screening strategies : 1) annually from ages 40-79 years ; 2) annually from ages 40-64 years and biennially from ages 65-79 years ; 3) annually from ages 40-49 years and biennially from ages 50-79 years ; and 4) annually from ages 40-79 years in high risk women (10%) and biennially from ages 40-49 years followed by annually from ages 50-79 years in normal risk women (90%). An additional strategy simulating hormone status and estrogen exposure was evaluated.

    Cost-effectiveness was expressed as marginal cost per year-life saved (MCYLS).


    The MCYLS varied from $18,800 to $16,100.

    For all strategies this was within the range of other generally acceptable diagnostic and therapeutic medical procedures.

    There was a 14% decrease in MCYLS from the least cost-effective to the most cost-effective strategy.


    Cost-effectiveness of four age-related mammographic screening strategies was evaluated.

    The MCYLS for all strategies was within a generally accepted range.

    With increasing concerns regarding the cost of health care, this information may be useful in health policy decision-making.
