The abnormal mammogram in women with clinically normal breasts
1Department of Surgery, Queen's University, Kingston, Ont.
Summary
Many women with normal breasts experience unnecessary surgical referrals due to abnormal mammograms. Improving mammogram interpretation can enhance screening efficiency and reduce patient anxiety.
Area of Science:
- Radiology
- Oncology
- Surgical Assessment
Background:
- Abnormal mammograms frequently lead to referrals for surgical breast assessment.
- Many women with clinically normal breasts are referred based solely on mammographic findings.
Purpose of the Study:
- To evaluate the impact of unnecessary surgical referrals from abnormal mammograms in women with clinically normal breasts.
- To identify strategies for improving the efficiency of managing these patients.
Main Methods:
- A case study design was employed.
- Data were collected from a breast clinic at a university-affiliated hospital.
- 475 women with asymptomatic, clinically normal breasts referred due to abnormal mammograms were analyzed.
Main Results:
- Only 42.5% of referred women had a significant clinical or mammographic abnormality.
- Among women with clinically normal breasts, only 26.7% required biopsy, and 9.7% had cancer.
- A substantial proportion of referrals were deemed unnecessary, indicating potential for improved screening efficiency.
Conclusions:
- Most women referred for abnormal mammograms do not have significant breast issues requiring surgical intervention.
- Implementing recommended measures can improve mammography screening efficiency, reduce patient anxiety, and control costs.
