A new study suggests apprehension about how breast-feeding will affect the appearance of their breasts may be the reason why some women with breast implants fail at nursing their babies.

According to HealthDay, researchers followed 160 mothers with breast implants to gauge their success with the feeding method. They found that 86 percent of those who failed at breast-feeding thought that it would make their breasts look worse. On the other hand, among those who successfully nursed their babies, only 13 percent believed that it would affect the appearance of their breasts.

"It makes sense that breast augmentation patients would be concerned about the effect breast-feeding could have on the appearance of their breasts," said the study's lead author. "After all, these women have invested both time and money into them. However, available evidence tells us that although breasts sag more with each pregnancy, breast-feeding doesn't seem to worsen these effects in women with or without breast implants."

Doctors involved with this study say that the results prove that more education is necessary for women with breast implants who plan on having children and breast-feeding. They insist that breast-feeding alone will not negatively affect the appearance of breast implants.

Breast augmentation surgery is one of the most common plastic surgeries. In fact, according to the American Society of Aesthetic Plastic Surgery (ASAPS), it has been the most popular cosmetic surgical procedure for the past three years, with more than 318,000 surgeries performed in 2010 alone.

Breast lift surgery is a procedure commonly used to repair the appearance of sagging breasts caused by pregnancy, weight loss and aging. While this procedure lifts and firms the breasts, it will not alter their overall size.
