What therapeutic mammoplasty is
Therapeutic mammoplasty combines cancer surgery with breast reduction techniques. The surgeon removes the tumour along with a generous margin of surrounding tissue, then uses the principles of reduction mammoplasty to reshape what remains into a natural, well-proportioned breast. The result is a breast that is treated and reshaped in a single operation.
This approach belongs to a family of techniques called oncoplastic surgery. It is particularly well-suited to patients who have a moderate to large breast and a tumour that would leave a noticeable dent or distortion after standard lumpectomy.
Who is suitable
The technique works best for patients with moderate to large breasts, where there is enough tissue to reshape after removing the tumour. As a general guide, tumours occupying up to 30 to 40 percent of the breast volume can often be removed this way with a good cosmetic result.
- Moderate to large breast size with adequate remaining tissue
- Tumour location that lends itself to reshaping, typically upper outer, central, or lower pole
- Patients who want breast conservation but are concerned about the cosmetic outcome of standard lumpectomy
- Patients who would benefit from breast reduction regardless of the cancer diagnosis
How it differs from standard lumpectomy
In a standard lumpectomy, the surgeon removes the tumour and a rim of normal tissue, then closes the cavity. In a larger breast, this can leave a visible indentation or change in shape. Therapeutic mammoplasty takes more tissue but then rearranges the remaining breast into a better shape, often producing a result that looks more even than before the surgery.
Because more tissue is removed, the technique also allows wider margins around the tumour, which reduces the risk of needing a re-excision for close or positive margins. This is a genuine clinical advantage, not just a cosmetic one.
Types of technique
The exact approach depends on where the tumour sits within the breast. Common pedicle designs include the superior pedicle, the inferior pedicle, and lateral approaches. The choice is driven by the tumour's location and how much tissue needs to be removed:
- Superior pedicle: suited to tumours in the lower pole of the breast
- Inferior pedicle: often used for centrally located tumours
- Lateral or other pedicle designs: chosen based on tumour position and surgeon preference
Dr. Shruthi plans the technique for each patient individually, taking imaging and tumour location into account before deciding on the incision design.
What about the other breast
After therapeutic mammoplasty, the treated breast will be smaller than before. If this creates a significant difference in size between the two breasts, a balancing reduction or uplift on the other side is often offered at the same time. This is called contralateral balancing surgery.
Many patients find this an unexpected benefit. Discussing symmetry surgery in advance means you only go through one operation and one recovery period, and the final result is both treated and balanced.
Radiotherapy to the treated breast is still recommended after therapeutic mammoplasty, as it is after any breast-conserving surgery. Dr. Shruthi coordinates with your oncology team to plan this.
Recovery
Recovery is similar to standard lumpectomy. Most patients go home the same day or after one night in hospital. You can expect two to four weeks before returning to your normal routine. The surgical wounds heal over six to eight weeks, and the final shape settles over several months.
Arm exercises and gentle movement are encouraged early. A supportive bra is worn for the first few weeks. Patients typically describe less discomfort than they expected.
