Breast screening: the case for physical examination without mammography

I Mittra1

Summary

Breast cancer screening with physical examination (PE) may be as effective as mammography in reducing mortality. PE offers significant human and economic advantages, questioning the necessity of mammographic screening.

Area of Science:

  • Oncology
  • Public Health
  • Diagnostic Imaging

Background:

  • Breast cancer screening aims to reduce mortality.
  • Mammography is the current standard screening method.
  • Physical examination (PE) is an alternative screening approach.

Purpose of the Study:

  • To compare the effectiveness of mammography versus physical examination (PE) in breast cancer screening.
  • To evaluate the benefits and costs associated with each screening method.
  • To question the necessity of current mammographic screening protocols.

Main Methods:

  • Review of existing studies on breast cancer screening effectiveness.
  • Comparative analysis of mammography and physical examination (PE) outcomes.
  • Assessment of human and economic costs for both screening methods.

Main Results:

  • Physical examination (PE) demonstrates comparable mortality reduction to mammography.
  • Mammography detects non-palpable tumors, but their clinical significance is uncertain.
  • PE offers substantial advantages in terms of human and economic costs.

Conclusions:

  • Physical examination (PE) may be a more cost-effective and equally effective method for breast cancer screening.
  • The necessity of widespread mammographic screening warrants re-evaluation.
  • Further research should focus on optimizing screening strategies based on efficacy and cost-benefit.
