Answer

Several biopsy techniques are available, including the following:

  • Fine-needle aspiration biopsy (FNAB)
  • Core needle biopsy
  • Incisional biopsy
  • Excisional biopsy

The choice of biopsy technique is based on the size and location of the mass and the experience of the surgeon. Excisional biopsy is indicated only for small, superficial masses (< 3-5 cm in greatest dimension), in which the probability of malignancy is low. Effective reexcision is more likely for smaller malignant lesions that initially are unintentionally treated as benign.
