Lumpectomy is a safe procedure that does not have many complications.

Routine postoperative complications include the following:

  • Hematoma

  • Infection

  • Poor cosmesis

  • Re-excision

Although re-excision is not a complication per se, it is something that needs to be explained clearly to the patient before surgery. A second operation to excise more breast tissue is needed in two circumstances:

  • If tumor cells are found close to the margin of the excised lumpectomy specimen when the procedure has been performed for a diagnosed breast cancer [8, 9]

  • If the final pathology reveals incompletely excised malignant or borderline phyllodes [4]
