In medicine, '''breast augmentation''' and '''augmentation mammoplasty''' are terms that describe a cosmetic surgery procedure that uses either a [[Breast implant|breast implant]] or a fat-graft to realise a [[mammoplasty]] to increase the size, change the shape, or alter the texture of the breasts, either as a cosmetic  procedure or as correction of [[congenital defect]]s of the breasts and the chest wall.<ref>{{Cite journal |last=Ors |first=Safvet |date=2017-12-01 |title=Incidence and Classification of Chest Wall Deformities in Breast Augmentation Patients |url=https://doi.org/10.1007/s00266-017-0953-5 |journal=Aesthetic Plastic Surgery |language=en |volume=41 |issue=6 |pages=1280–1290 |doi=10.1007/s00266-017-0953-5 |issn=1432-5241|url-access=subscription }}</ref><ref>{{cite web |title=Top Reasons for Breast Augmentation - Dr. Vikesh Vij |url=https://drvikeshvij.com/blog/top-reasons-for-breast-augmentation/ |date=25 September 2024}}</ref>

To augment the breast hemisphere, a breast implant filled with either [[saline (medicine)|saline]] solution or a [[silicone gel]] creates a [[sphere|spherical]] augmentation. The fat-graft transfer augments the size and corrects contour defects of the breast hemisphere with grafts of the [[Adipose tissue|adipocyte fat tissue]], drawn from the body of the woman. In a breast reconstruction procedure, a [[Tissue expansion|tissue expander]] (a temporary breast implant device) is emplaced and filled with saline solution to shape and enlarge the implant pocket to receive and accommodate the breast-implant prosthesis.

In most instances of fat-graft breast augmentation, the increase is of modest volume, usually only one [[bra]] cup size or less,<ref>{{Cite web |title=Fat Transfer Breast Augmentation: Procedure, Results & Risks |url=https://my.clevelandclinic.org/health/treatments/24033-fat-transfer-breast-augmentation |access-date=2024-05-01 |website=Cleveland Clinic |language=en}}</ref> which is thought to be the physiological limit allowed by the metabolism of the human body.<ref>''Cell-assisted Lipotransfer for Cosmetic Breast Augmentation: Supportive Use of Adipose-Derived Stem/Stromal Cells'' (2007) {{Cite journal | last1 = Yoshimura | first1 = K. | last2 = Sato | first2 = K. | last3 = Aoi | first3 = N. | last4 = Kurita | first4 = M. | last5 = Hirohi | first5 = T. | last6 = Harii | first6 = K. | doi = 10.1007/s00266-007-9019-4 | title = Cell-Assisted Lipotransfer for Cosmetic Breast Augmentation: Supportive Use of Adipose-Derived Stem/Stromal Cells | journal = Aesthetic Plastic Surgery | volume = 32 | issue = 1 | pages = 48–55; discussion 56–7 | year = 2007 | pmid = 17763894 | pmc =2175019 }}</ref>
