When woman has a plastic breast surgery and few years later she gets pregnant, can she still breast feed the baby?

Almost always: Exception is an incision around the areola that disrupts the glands, or breast reduction or breast lift that somehow disrupts glands. But even that is a little unusual.

Breast feeding: Breast implants have no bearing on ability to breast feed. Any surgery on the breast can affect it. Also you may not be able to breast feed anyway.

Depends.: Any surgical procedure on the breasts carries the potential risk of decreasing a woman's ability to breast-feed. Exactly how much risk is involved will depend on exactly what procedure is performed. Generally speaking, the more the surgery involves the breast gland tissue and the lactiferous ducts, the greater the risk. Hope this helps.
