The develepment of keloids are very unpredictable. I'll give you an example. Suppose a patient sustains two identical injuries, one on the left arm and one on right arm. A keloid may develop on one arm, both arms, or neither arm. Its totally unpredictable.
If you have a history of keloid scars, there is a higher chance that you will develop them on your breasts after surgery.
Typically, an experienced surgeon would advise you against performing elective surgery as the risk of poor scars is higher in someone with your history.
Keloids are quite difficult to treat. You should seriously discuss these issues with your plastic surgeon and weigh the benefits of breast lift (mastopexy) vs. poor scars.
Finally, the goal of a breast lift without implants is to improve the appearance of your breasts in the nude, not in clothes. If you feel that you would be accepting of a breast scar that may be noticeable in the nude, then you may discuss breast lifting with your surgeon.
