Capsular contracture

Capsular contracture is the most common complication in interventions of breast implants
Once a breast implant is in place, fibrous scar tissue forms around it, creating a tissue capsule.
The body forms a protective capsule like this around any object it recognizes as foreign.

The tissue capsule is usually soft or slightly firm, not noticeable, and helps to keep the implant in place.
In some women, a tissue capsule forms that is unusually hard and dense.
The capsule tightens around and squeezes the implant.
This condition, called capsular contracture, can cause chronic pain and distortion in the shape of the breast, and it can make the breast rise higher on the chest.

Signs of capsular contracture, such as increasing firmness or tightness in the breast, can start to appear as early as a few months after your implant reconstruction surgery or years later.
