Chest surgery (Breast Surgery)
Chest surgery (Breast Surgery) is a surgical procedure on the chest to alter the size or shape of the breasts. In some cases, it is done to address health issues, while in other cases, it is performed for aesthetic purposes—such as desiring a different size or a more pleasing shape. There are several surgical techniques depending on the purpose of the surgery and other factors, such as the patient’s goals. Examples include breast reduction or removal for gender transition from female to male, which is a common procedure among women and transmasculine individuals.
FTM Top Surgery (Top Surgery for Female-to-Male) — What is it?
FTM Top Surgery is a procedure to reshape the chest so that a trans man’s physique appears male. The surgeon removes breast tissue, excess skin near the armpits, and performs liposuction to refine the chest contour to match the patient’s body proportions. The nipples and areolas are also reshaped and repositioned to resemble those of a typical male chest. This is one of the most popular gender-affirming surgeries for female-to-male transitions.

Who is Chest Surgery Suitable For?
Top surgery is suitable for individuals who wish to remove breast tissue to achieve a flat, masculine chest appearance. Patients are usually trans men or female-to-male transgender individuals, but the procedure can also help men with gynecomastia (enlarged male breasts).
