Breast implant capsular contracture occurs when scar tissue around an implant tightens, causing hardness, pain, or distortion. It can develop due to inflammation, infection, or the body’s immune response. Symptoms range from mild firmness to severe discomfort and misshapen breasts. Treatment options include massage, ultrasound therapy, and medication in early stages. Severe cases may require capsulectomy (scar tissue removal), implant replacement, or fat grafting to restore natural shape and softness.
