ABSTRACT

Background: Breast cancer is the leading cause of cancer related death in females. Around 90% of breast lumps are benign. However, a breast lump can be a sign of cancer. Ultrasound is the commonly available tool to evaluate the breast lump as well as for the biopsy. Breast lump may be solid or cystic lesion which cannot be differentiated by palpation. If we do palpation guided biopsy there is chance of false negativity as we are not sure from which site we have taken the biopsy. However, ultrasound may not be available in surgical outpatient unit or for surgeons and it is requires expertise compared to palpation guided biopsy. So we are comparing the diagnostic accuracy of palpation guided biopsy with ultrasound guided biopsy. Materials and method: This is a retrospective study done BPKIHS. All patients during the study period undergoing either palpation guided core biopsy or USG guided core biopsy were included in the study. Result: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for palpation guided core biopsy while comparing to the final excisional biopsy was 64%, 100%, 100%, 98.95% and 86.57% respectively while that of USG guided was 94.55%, 100%, 100%, 99.84% and 95.52% respectively. Conclusion: The accuracy and sensitivity of image guided core biopsy is found to be better when compared to palpation guided.
