Risk versus benefit in mammography

R G Lester

    Radiology
    |July 1, 1977

    Summary

    Mammography screening for women aged 35-49 is debated. Modern mammography uses lower radiation doses, revealing nonpalpable breast cancers, supporting its diagnostic use in this age group.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging

    Background:

    • Debate exists regarding mammography's utility for asymptomatic women aged 35-49.
    • Routine mammography is accepted as beneficial for women over 50.
    • Concerns about radiation-induced cancer risk from mammography have been raised.

    Purpose of the Study:

    • To evaluate the effectiveness of mammography in detecting breast cancer in asymptomatic women aged 35-49.
    • To address concerns about radiation exposure from mammography in this demographic.
    • To present evidence supporting mammography as a diagnostic tool for nonpalpable breast cancers.

    Main Methods:

    • Analysis of data on breast cancer detection rates in women aged 35-49 using mammography.
    • Review of absorbed radiation doses from contemporary mammography equipment.
    • Comparison of current radiation doses with historical data.

    Main Results:

    • Significant numbers of breast cancers were detected in women aged 35-49 via mammography.
    • Modern mammography delivers half to one quarter of the radiation dose previously assumed.
    • Evidence suggests a reduced radiation carcinogenic risk at current diagnostic levels.

    Conclusions:

    • Mammography is effective in diagnosing nonpalpable breast cancers in women aged 35-49.
    • Lower radiation doses in modern mammography mitigate safety concerns.
    • Mammography is recommended for the diagnosis of early-stage breast cancer in this age group.
