A thin layer of scar tissue normally forms around every breast implant. Capsular contracture occurs when this capsule becomes unusually tight and compresses the implant. The exact cause cannot always be identified.
Factors associated with a higher risk may include bleeding or hematoma, infection or bacterial contamination, fluid collection, implant rupture, prior radiation treatment, implant and pocket characteristics, and an individual tendency to form firm scar tissue.
Careful surgical technique and postoperative follow-up can reduce some risks, but capsular contracture cannot be prevented in every patient. Contact the clinic if a breast becomes progressively hard, painful, higher in position, or visibly different.
