===Implants and breastfeeding===
The breasts are [[Apocrine|apocrine glands]] which produce [[milk]] for the feeding of infant children,<ref name="Tortora, Gerard J.">Tortora, Gerard J. ''Introduction to the Human Body'', Fifth Edition. John Wiley & Sons, Inc.: New York, 2001. p. 560.</ref>

====Breast implant toxicity====
Digestive tract contamination and systemic toxicity due to the leakage of breast implant filler to the breast milk are the principal infant health concerns with breast implants. Breast implant fillers are biologically inert: [[silicone]] filler is [[Digestion|indigestible]] and saline filler is mostly salt and water. Each of these substances should be chemically inert and present in the environment.{{citation needed|date=February 2020}}<!--sources must somehow make the doubtful case that silicones are ubiquitous in modern life--> Moreover, "proponent" physicians have stated that there "should be no absolute contraindication to breast-feeding by women with silicone breast implants."<ref>{{cite journal|author=Berlin, C.

====Impediments to breastfeeding====
A person with breast implants is usually able to [[Breastfeeding|breastfeed]] an infant; yet implants can cause functional breastfeeding difficulties, especially with [[mammoplasty]] procedures that involve cutting around the areola, and implant placement directly beneath the breast, which tend to cause greater breast-feeding difficulties. Patients are advised to select a procedure that causes the least damage to the [[lactiferous duct]]s and the nerves of the nipple-areola complex (NAC).<ref>[http://www.llli.org/NB/NBsurgery.html Breastfeeding after Breast Surgery] {{Webarchive|url=https://web.archive.org/web/20101230173437/http://www.llli.org/NB/NBsurgery.html |date=2010-12-30 }}, La Leche League (2009-09-05).</ref><ref>[http://www.llli.org/cbi/bibimplant.html Breastfeeding and Breast Implants] {{Webarchive|url=https://web.archive.org/web/20101231121338/http://www.llli.org/cbi/bibimplant.html |date=2010-12-31 }}, Selected Bibliography April 2003, LLLI Center for Breastfeeding Information.</ref><ref name="slate">Beam, Christopher (2009-12-11).

Functional breastfeeding difficulties arise if the surgeon cuts the milk ducts, the major nerves innervating the breast, or if the milk glands are otherwise damaged. Some surgical approaches, including IMF (inframammary fold), TABA (trans-axillary breast augmentation), and TUBA ([[trans-umbilical breast augmentation]]), avoid the tissue of the nipple-areola complex; if the person is concerned about possible breast-feeding difficulties, the periareolar incisions can sometimes be made so as to reduce damage to the milk ducts and to the nerves of the NAC. The milk glands are affected most by subglandular implants (under the gland) and large-sized breast implants, which pinch the lactiferous ducts and impede milk flow. Small-sized breast implants, and submuscular implantation, cause fewer breast function problems; however, some women have managed to successfully breastfeed after undergoing periareolar incisions and subglandular emplacement.<ref name="slate"/>
