Surgery to the Breast: Breast Conservation Techniques
Breast-conserving surgery removes the cancer while preserving as much healthy breast as safely possible.
The key things to know
- Clear margins are central to the operation.
- Radiotherapy is usually part of conservation treatment.
- Some people need a second operation for margins.
What the operation removes
Lumpectomy, wide local excision, and partial mastectomy are names used for removing a breast tumour with a surrounding rim of tissue. The aim is clear margins while keeping the remaining breast. If a lesion cannot be felt, imaging-guided localisation may help the surgeon find it. The exact technique depends on the lesion's size, position, extent, and the breast's shape.
Who may be suitable
Many people with early breast cancer or localised DCIS can consider breast conservation. Suitability includes whether the disease can be removed completely with an acceptable cosmetic result and whether the needed radiotherapy is feasible. Treatment before surgery may shrink some tumours enough to make conservation possible. More than one area of disease requires careful assessment rather than a simple rule based only on tumour count.
Why margins and radiotherapy matter
The pathologist checks the edges of the removed tissue. If tumour reaches a margin, another operation may be needed. Radiotherapy is usually part of breast-conserving treatment and helps reduce recurrence within the breast. In selected low-risk cases, omission may be discussed with specialists. For appropriately selected patients, conservation with radiotherapy provides survival comparable to mastectomy.
Shape, recovery, and follow-up
There may be a scar, change in size, or indentation. Oncoplastic techniques can redistribute tissue or use nearby tissue to improve contour when appropriate. Recovery depends on the operation and any node surgery. Follow wound and exercise advice, attend the pathology review, and keep the imaging follow-up plan. New persistent changes should be assessed rather than assumed to be scar tissue.
