The U.S. Food and Drug Administration (FDA) has approved a silicone gel-filled breast implant manufactured by Sientra for breast size augmentation in women at least 22 years old and to rebuild breast tissue in women of any age.
As a condition of clearance, Sientra will continue to follow 1,788 clinical trial participants from their premarket study for seven more years. The company will also conduct a 10-year study of 4,782 women who received Sientra breast implants to collect information on long-term local complications such as capsular contracture, as well as less common disease outcomes including rheumatoid arthritis and breast and lung cancer.
The company will also conduct five case-controlled studies to evaluate the association between Sientra's silicone gel-filled breast implants and five rare diseases: rare connective tissue disease, neurological disease, brain cancer, cervical/vulvar cancer, and lymphoma.
In a prepared statement, Dr. William Maisel, deputy director for science in the FDA's Center for Devices and Radiological Health, said the data on silicone gel-filled breast implants continue to demonstrate a reasonable assurance of safety and effectiveness.
Currently, there are three FDA-approved silicone gel-filled breast implants in the U.S. manufactured by Allergan, Mentor, and Sientra.










![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
