Answer

The indications for performing a lumpectomy may be diagnostic or therapeutic.

Indications for a diagnostic lumpectomy include the following:

  • Equivocal pathology obtained on core biopsy or fine needle aspiration cytology of a radiologically suspicious breast lump

  • A lump classified as category 3 or 4 by the Breast Imaging-Reporting and Data System that is close to the pectoral muscle, which makes biopsy under radiologic guidance difficult

Indications for a therapeutic lumpectomy include the following:

  • Benign breast lumps, such as fibroadenoma or phyllodes [5]

  • Ductal carcinoma in situ or invasive breast cancer that is amenable for breast conservation based on the size of the lesion [6, 7]
