Capsular contracture is a condition where scar tissue forms around a breast implant, causing the implant to harden and distort. It occurs when the body’s natural healing process creates a capsule around the implant, which can sometimes tighten excessively. Symptoms range from mild discomfort and firmness to severe pain and visible implant distortion. Capsular contracture is categorized into four grades, from mild to severe. Treatment options include massage, ultrasound therapy, or surgery in more severe cases.
