    Radiographically guided localization successfully identified occult breast lesions in 500 patients over 5 years. Over 23% of these lesions were malignant, highlighting the importance of this diagnostic tool for early breast cancer detection.

    Area of Science:

    • Radiology
    • Oncology
    • Breast Imaging

    Background:

    • Occult breast lesions pose diagnostic challenges.
    • Accurate localization is crucial for timely biopsy and treatment.

    Purpose of the Study:

    • To evaluate the efficacy of preoperative radiographically guided localization for occult breast lesions.
    • To determine the malignancy rate and characteristics of these lesions.

    Main Methods:

    • Retrospective analysis of 500 cases undergoing radiographically guided localization.
    • Review of biopsy results and axillary lymph node status.

    Main Results:

    • 117 (23.4%) of 500 lesions were malignant.
    • Biopsies were prompted by calcifications (41%) or masses/distortions (59%).

  • 78% of carcinoma patients had no metastatic axillary lymph node involvement.

    • Conclusions:

    • Preoperative radiographically guided localization is effective for occult breast lesions.
    • A significant proportion of localized lesions are malignant, necessitating further investigation.
    • Early detection through localization may be associated with favorable nodal status.
