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
