Your body forms a scar-tissue pocket, called a capsule, around a breast implant. That capsule may remain soft or become tight, thickened, or otherwise abnormal. Not every implant concern requires capsule removal. [1]
In surgical terminology, en bloc capsulectomy means removing the implant and capsule with a margin of surrounding uninvolved tissue for suspected or established implant-associated cancer. Removing the implant inside an unbroken capsule without that tissue margin is an intact total capsulectomy, not the same operation. [2]
New persistent swelling, a lump, pain, or a change around an implant deserves evaluation before deciding on surgery. Imaging and testing of fluid or tissue may be needed. If cancer is suspected, those results help the surgical and oncology teams plan treatment. [2]
Why does the terminology matter?
The term “en bloc” is sometimes used loosely to describe any intact capsule removal. Ask your surgeon whether the plan includes a margin of surrounding tissue, why that margin is needed, and how the operation differs from total capsulectomy.
What cancers are part of this discussion?
Breast implant-associated anaplastic large cell lymphoma, or BIA-ALCL, is a lymphoma that usually develops in fluid or scar tissue around an implant, rather than in breast tissue. It is associated predominantly with textured implants. Rare squamous cell cancers and other lymphomas have also been reported in implant capsules. These conditions require diagnosis-specific care.
