Study of breast implant movement after cosmetic breast augmentation
This study looks at why breast implants shift or rotate (move from their original position) after cosmetic breast augmentation. It will follow you for 2 years after your surgery to see if the type of implant or how it was placed affects this, which could help you and your doctor choose the best option.

Tracking breast implants over time to study cracks
This study follows women with cosmetic breast implants over time to see if certain features (like age of implant or type of surgery) are linked to the implant shell developing tiny cracks or tears. By tracking participants, researchers hope to learn how to predict and prevent these issues.

- Yes. Clin2 currently lists 562 recruiting cohort studies studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cohort studies trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cohort studies trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
