What really determines breast size
Mainly genetics — though hormonal changes and weight fluctuations over a lifetime also play a role.
What options are on the table
Classic augmentation with implants, or, in selected cases, techniques using the patient's own fat tissue. What makes sense depends on the individual anatomy and expectations — which is why the doctor decides during consultation.
An informed decision starts with a consultation
This article explains “Small Breasts — What Determines Size and How It Can Be Changed”, but a procedure requires an individual qualification. The surgeon should discuss the goal of treatment, possible techniques, scars, recovery, risks and available alternatives.
Bring your questions to the consultation and disclose health conditions, medicines, smoking and previous procedures. This helps assess safety, the scope of treatment and realistic expectations.
