I developed a keloid from a skin cancer biopsy on my upper chest and am fearful that a keloid could develop from BA incisions.

Thank you for your question.

Unfortunately, if you already had a keloid scar, then you
are at increased risk of developing another unless the keloid appeared on the
earlobe, which is not the case in this scenario.

It is recommended that unless important, all non-essential surgery
should be avoided when there is high risk of keloid formation.

Here is some information that would help you decide whether
to go ahead with breast augmentation surgery and take the risk or not.

Keloid occurrence is 15 times higher in persons with dark
and highly pigmented skin. Keloid are also more common in persons between the age of
10-30 years. There may be a genetic link, and so if you have an extensive
family history of keloid occurrence and recurrence, then you have to consider
this.Interestingly, higher rates of keloid are also seen in
patients with type A blood group.In individuals at risk of keloid recurrence, the sternal
skin (where you have it currently), shoulders, upper arms, earlobes, and cheeks
are most susceptible. Excessive trauma as caused by burns, ear piercing, biopsy
procedures, and lacerations are more likely to result in keloids, especially
when there is an infection.Finally, if there is high risk of keloid formation, surgeons
can take precautionary measures to prevent with immediate silicone elastomer sheeting,
taping to reduce skin tension, or corticosteroid injections.

So having this information, consult with a board-certified plastic
surgeon and hopefully something can be done.

Best of luck!

Some areas are more likely to develop poor scar than others.  Above your nipples, deltoid areas, and midline torso areas are more likely to form widened scars.Breast augmentation with fold incisions rarely produce bad scars even on patients who have poor scars in other areas.Best Wishes,Nana Mizuguchi, MD
