Needle localization under mammographic guidance

Abstract

Within the medical history of cancer, breast cancer is a prevalent form of cancer affecting Thai women and globally. To enhance the survival rates of breast cancer patients, it is crucial to undergo regular annual mammogram screenings. Early detection of lesions facilitates prompt initiation of treatment. Surgical intervention remains the most effective treatment method for patients whose lesions are detected at an early stage. This is particularly true for non-palpable lesions or those with ill-defined margins. In such cases, needle localization techniques become necessary to precisely determine the lesion’s location prior to surgical intervention. This facilitates accurate surgical procedure and comprehensive lesion removal. The choice of needle localization technique depends on the lesion’s location and the availability of specific instrument at the healthcare facility. This article provides a comprehensive overview and description of needle localization for lesion identification under mammographic guidance. It encompasses the indications for the procedure, including two-dimension and three-dimension mammographic techniques, the requisite devices and needle techniques employed, potential limitations, and associated patient risks during the procedure.
