What Is Breast Implant Illness (BII)?
Breast Implant Illness (BII) is a term used by patients and some practitioners to describe a range of symptoms that appear after breast augmentation with implants—especially silicone implants. While not yet officially recognized as a distinct medical diagnosis, many women report feeling chronically unwell post-augmentation and link their symptoms to their breast implants.
It’s important to note that BII is not the same as a rupture, capsular contracture, or ALCL (Anaplastic Large Cell Lymphoma). Instead, it refers to a systemic reaction possibly linked to the body’s immune response to foreign materials.
