This study is a single-center prospective, randomized and quasi double blinded pilot study. The study has 2 parallel arms, each arm involved around 54 patients. Targeted community is the newly diagnosed adults with non metastatic and non inflammatory breast cancer in King Hussein Cancer Center who require axillary biopsy as part of their staging work up. The study aims to improve the intra-operative identification of the preoperatively suspicious and biopsied lymph nodes and test the concordance between the pre-operative clinical suspicion and histopathological results of these node; by comparing between preoperative marking of biopsied axillary lymph nodes with two different modalities (clipping Vs tattooing) and testing its concordance with sentinel lymph node biopsy, both in upfront surgery and neoadjuvant chemotherapy settings and in a prospective, randomized and quasi double blinded design
