There is always a risk of bad scarring with any surgery, even on the breast. Having a history of keloids or hypertrophic scarring will increase your risk compared to other women having the same procedure who have not had a history of keloids.
There are, however, some things that can be done to minimize your risk, and these should be discussed with your surgeon in advance:
Using silicone sheet therapy after the procedure (this looks essentially like a large band-aid for all of the incisions, stays on day and night except for showering for a minimum of 6 weeks, doesn't hurt, but seems to help scars soften and flatten)
Steroid injections after surgery, even if the scars look reasonable, as a prophylatic measure.
In the end, you will need to ask yourself if you are willing to trade the risk of bad scars for a better shape to your breast-- if the answer is yes, then a breast lift is an option. Otherwise, be cautious.
Hope that helps,
Dr. S
