A 4-week cessation of hormone replacement therapy (HRT) before mammography did not significantly alter mammographic density or breast pain in women undergoing screening. This finding suggests short HRT breaks may not improve mammogram sensitivity.

Area of Science:

  • Radiology
  • Oncology
  • Endocrinology

Background:

  • Hormone replacement therapy (HRT) increases breast density, potentially reducing mammography sensitivity for breast cancer detection.
  • Limited evidence exists on the impact of short-term HRT cessation on mammographic density.
  • Optimizing screening sensitivity in women using HRT is crucial for early breast cancer diagnosis.

Purpose of the Study:

  • To investigate the effect of a 4-week cessation of HRT on mammographic density.
  • To assess changes in breast pain and tenderness associated with HRT cessation before mammography.

Main Methods:

  • Mammographic density was assessed in 48 women on HRT before and after a 4-week HRT cessation using visual scales and computer-assisted methods.
  • Statistical analysis included Wilcoxon signed-rank test and paired t-test to compare pre- and post-cessation measurements.

  • Breast pain, tenderness, radiation dose, compression force, and breast thickness were also recorded.

    • Main Results:

    • No statistically significant changes in mammographic density were detected by any assessment method after 4 weeks of HRT cessation.
    • Breast pain and tenderness during mammography remained unchanged.
    • Radiographic measurements, including radiation dose and compression force, were not significantly altered.

    Conclusions:

    • A 4-week cessation of HRT prior to mammography does not significantly impact mammographic density in this screening population.
    • Short-term HRT interruption does not appear to alter key mammographic parameters or patient comfort.
    • Further research may be needed to determine optimal HRT management strategies for breast cancer screening.
