Core biopsy may be performed when a suspicious lump is found, for example a breast lump or enlarged lymph node or if abnormality is detected on an imaging test such as x-ray, ultrasound or mammography.
Core biopsy is a more invasive procedure than fine needle aspiration biopsy, as it involves a local anaesthetic. However, it is quicker and less invasive than a surgical biopsy. In some cases, the result of a core biopsy will prevent the need for surgery to take place.

- Inadequate: The sample taken was not adequate to exclude or confirm a diagnosis of cancer.
- Benign: There are no cancerous cells present.
- Atypical/ Intermediate, suspicious of malignancy: Some cells appear abnormal but are not definitely malignant so a surgical biopsy is required for proper diagnosis.
- Malignant: show malignant criteria (loss of polarity, pleomorphism, increased nucleocytoplasmic ratio, hyperchromasia, abnormal mitosis, etc.)
- Bleeding, swelling, fever or pain (rare).
- Core biopsy may leave a very small, fine scar, which usually fades with time.
