Durham, North CarolinaAges 18 years+ - NCT07087691Recruiting
Testing a device to mark breast cancer for surgery and monitoring
This trial tests a device called OneMark that helps doctors find and track breast cancer during surgery and follow-up. It may help make sure the cancer is removed completely.
La Jolla, CaliforniaAges 18 years+ - NCT07075679Recruiting
AI vs double reading for breast cancer screening
This study compares a single radiologist reading your mammogram with help from artificial intelligence (AI) to the standard method of two radiologists reading it. The goal is to see if AI-assisted reading is just as good at finding cancer while saving time and resources.
OlomoucAges 45–69 - NCT07047365RecruitingPhase 3
New drug for HER2-positive advanced breast cancer
This trial tests a new medicine called TQB2930 for people with advanced breast cancer that is HER2-positive. It is for those who have already had at least two prior anti-HER2 treatments and are willing to also receive chemotherapy chosen by their doctor.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 recruiting breast cancer 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 breast cancer 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 breast cancer 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.
