## TL;DR

A new surgical technique is used to treat breast cancer in Asian patients while avoiding visible scars and achieving good cosmetic results.

## Contribution

The Lalonde technique is successfully applied to Asian patients with ptotic breasts in oncoplastic breast-conserving surgery.

## Key findings

- The Lalonde technique allowed complete tumor resection without vertical scars in an Asian patient.
- The procedure resulted in excellent cosmetic outcomes for a patient with macromastia and breast cancer.
- This case demonstrates the feasibility of the Lalonde technique in Asian populations with ptotic breasts.

## Abstract

Oncoplastic breast-conserving surgery combines oncological resection with plastic surgery techniques, including reduction mammoplasty, to achieve effective cancer control and superior cosmetic outcomes.

Traditional approaches, such as vertical scar mammoplasty and inverted-T mammoplasty, have enabled extensive tumor resection but are often associated with the drawback of vertical scars. The Lalonde technique has been reported in Western patients to allow extensive partial mastectomy without leaving vertical scars. Here, we present the case of a 60-year-old Asian woman with macromastia and breast cancer who underwent reduction mammoplasty using the Lalonde technique. The postoperative outcomes revealed complete tumor resection alongside excellent cosmetic results. This case highlights the potential and possibilities of applying the Lalonde technique to Asian patients with ptotic breasts, and offers a promising and aesthetically superior option as one of the new oncoplastic surgery techniques.
