Breast biopsy techniques in a global setting-clinical practice review.

Breast cancer is a disease of global concern, regardless of economic status. A significant disparity in breast cancer care between low- and high-income countries is not unexpected, but consideration can be given to particular aspects of therapy to allow as much equitability as possible. One of these aspects involves biopsy of breast lesions. With available resources, management in developed countries focuses on dealing with screening and image-detected lesions. In such circumstances, advanced percutaneous biopsy techniques are utilized liberally. However, where resources are less forthcoming for mammographic screening, women frequently present with symptomatic, palpable and larger tumours. This scenario behooves the clinician to modify treatment approaches and yet use cost-effective management strategies. It is essential that thought is applied to breast biopsy technique used where there is cost-consciousness as it significantly influences subsequent therapy. Less expensive strategies like fine needle aspiration cytology (FNAC) and core needle biopsy (CNB), when performed with particular attention to technique, handling, transportation and preparation of biopsy specimens allows a high level of accuracy and provides adequate information for the next steps in treatment. This mini-review discusses the variation in biopsy approaches among lower and higher income areas and offers suggestions for appropriate breast biopsy strategies in resource-limited countries.
