Capsular contracture is a complication after a breast augmentation procedure that can happen from a few months post-surgery to decades later.
Around all implants, a fibrous capsule (scar tissue) is formed to keep it in place and protected.
For reasons that are not totally understood, this capsule can sometimes become thicker and contract. In its severe form, it causes discomfort and can distort the breasts. In these rare circumstances, the capsule needs to be surgically removed and the implant replaced.
