:* If no recurrence, resume routine follow-up
*Core needle biopsy
:* If recurrence, can repeat aspiration
*Open surgical biopsy
:* Consider biopsy if further recurrence
* Non-bloody fluid but residual mass after aspiration: surgical biopsy
* Solid mass (no fluid)
:* Surgical biopsy or fine needle aspiration biopsy
====Fine Needle Aspiration Biopsy (FNAB)====
* Aspiration of cells from a solid mass
* 21 gauge needle, operator-dependent
* Wide variation in sens (65-98%), spec (34-100%)
====Core Needle Biopsy====
* 14-18 gauge needle allows for better histologic sample
* Used mostly for evaluation of non-palpable masses (mammogram or ultrasound guidance)
* Compares favorably with surgical biopsy at lower cost
====Excisional Biopsy====
* Recommended if solid mass suspicious for cancer by exam or mammo
* Also recommended for palpable mass not seen on mammogram or for abnormal biopsy

The only certain method to approve the presence of breast malignancy is breast lump biopsy [1]


There are three types of biopsy [2]

  • Fine needle biopsy [3]
  • Core needle biopsy
  • Open surgical biopsy
