NCT00225927

Brief Summary

The purpose of this study is to determine whether a new surgical technique (radioguided seed localization) for localizing nonpalpable breast tumours is better than the standard technique (needle localization).

Outcome Measures

Primary Outcomes (1)

  • Compare the number of positive margins following excision of the nonpalpable breast tumours for the two different surgical techniques

    immediate post-operative pathology results

Secondary Outcomes (1)

  • Compare procedure times, complications and volume of tissue excised for both techniques

    intra-operative

Interventions

radio-labelled (I-125) titanium seed inserted via needle into nonpalpable breast lesion and gamma probe used to guide surgery
