Recruiting studies
- NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.

Using a green dye to map lymph nodes in breast cancer surgery
This trial tests if an injection of indocyanine green dye can help surgeons find and remove only the key lymph nodes in the armpit during breast cancer surgery. It aims to reduce the need for more extensive lymph node removal.
Peschiera del Garda, VeronaAges 18 years+ - NCT07441889RecruitingPhase 1/Phase 2
HER2-targeting immune cells for metastatic breast and prostate cancer
This trial tests a new treatment using specially designed immune cells that target HER2, a protein found on some cancer cells. It is for people with metastatic breast or prostate cancer that has worsened after prior treatments.
Charlottesville, VirginiaAges 18 years+ - NCT07447700Recruiting
Massage therapy during radiation for breast cancer
This study tests if focused chair massages after each radiation treatment can help with pain, movement, and quality of life for breast cancer patients. You would receive massages during your radiation treatment period.
Columbus, OhioAges 18 years+ - NCT07455188Recruiting
Switching targeted therapies for advanced HER2-positive breast cancer
This trial tests whether switching between two targeted therapy combinations can help women with HER2-positive advanced breast cancer that has progressed after previous treatments. It aims to find a new effective option for people who have already tried one or two lines of therapy.
Zhejiang, HangzhouAges 18 years+ - NCT07457359RecruitingPhase 2
Toripalimab plus radiation for chemo-resistant triple-negative breast cancer
This trial tests if combining an immunotherapy drug (toripalimab) with targeted radiation (SBRT) can help people with triple-negative breast cancer that did not shrink after initial chemotherapy. It aims to improve outcomes before surgery.
HangzhouAges 18–75 - NCT07461454RecruitingPhase 3
Comparing YL202 to other treatments for HR+/HER2- breast cancer
This trial tests a new drug called YL202 against other treatments chosen by your doctor for people with a certain type of advanced breast cancer (HR+/HER2-). It aims to see if YL202 works better. You may join if your cancer has spread, you've already tried chemotherapy, and you meet other health criteria.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07465393Recruiting
Facility rehab vs home exercise for breast cancer survivors
This trial compares two types of exercise programs for breast cancer survivors to see which one improves quality of life more. You will either attend supervised rehab sessions at a facility or follow a resistance exercise program at home.
New Taipei City, Xindian DistAges 18 years+ - NCT07469267Recruiting
Armpit radiation vs more surgery for early breast cancer with node spread
This trial tests whether radiation to the lower armpit (level I-II axilla) works as well as more extensive surgery for women with early-stage breast cancer that has spread to one or two sentinel lymph nodes (with cancer size > 2 mm). It aims to find a gentler treatment that still keeps the cancer from coming back.

Common questions
- Are there clinical trials for breast?
- Yes. Clin2 currently lists 2,691 recruiting breast 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 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 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.
