When a breast implant is placed, the body naturally forms a thin layer of scar tissue around it. This layer is called a capsule. The capsule is the body’s normal way of protecting itself from any foreign object, like medical devices or implants.
When the Capsule Helps With Healing
In most women, the capsule stays thin and soft. This is normal and healthy. In fact, the capsule can even help in breast revision surgery. Surgeons may use it to reshape the implant pocket, which can make the breast look more natural and balanced.
When the Capsule Becomes a Problem
Sometimes, the capsule becomes too thick or tight. This happens in about 3–10% of patients. When the scar tissue squeezes the implant, it causes a problem called capsular contracture. This can change the look of the breast, making it feel firm or uneven. It may even cause pain.
In rare cases, especially with older implants that are more than 20 years old, the capsule may become very hard or even develop calcium deposits. When this happens, surgeons often remove the capsule to improve comfort, breast shape, and healing.
The Bottom Line
The capsule around a breast implant is usually safe and helpful. Most of the time, it goes unnoticed. But if it thickens, hardens, or causes changes in the breast, surgery may be needed to remove or reshape it.
