Capsular contracture is a condition where scar tissue, or the capsule, forms tightly around a breast implant, causing it to harden and potentially distort its shape. It is a common complication of breast augmentation or reconstruction, ranging in severity from mild firmness to significant discomfort and aesthetic changes. Causes include infection, implant rupture, or the body’s natural immune response. Symptoms may include pain, tightness, or an unnatural implant appearance. Proper surgical technique and post-operative care help reduce risks.
