Recruiting studies
- NCT07047495Recruiting

This study tests a plan meant to reduce how often people get a breast biopsy when the abnormality looks suspicious but not highly worrisome. It may help more people avoid unnecessary procedures while still keeping close medical follow-up.
Pittsburgh, PennsylvaniaAges 30 years+ - NCT05216900Recruiting
Breast reconstruction with radiation given before surgery
This study looks at how breast reconstruction works when radiation is planned around the time of surgery, including in some people before surgery depending on lymph node results. It may help improve safety and outcomes for people needing mastectomy and chest/radiation therapy.
Bilthoven, UtrechtAges 18–75 - NCT05222100Recruiting

This trial looks at whether having breast implants changes what happens during routine breast cancer screening with mammograms. It may help improve how screening is done and understood for people with implants.
GothenburgAges 40–75 - NCT05289258Recruiting
Barlow-style program for thinking and memory problems after breast cancer
This trial tests a structured “Barlow Protocol” program to help improve mild to moderate thinking and memory problems in people who finished breast cancer chemotherapy. It may help if your cognitive symptoms started after treatment and you’re not already in similar therapy.
CórdobaAges 18–70 - NCT06146231Recruiting
Breast reconstruction with Motiva implants and fat grafting
This study tests a new breast reconstruction method using Motiva Flora implants and your own fat to rebuild the breast after a mastectomy. It is for women who need tissue expansion as part of their reconstruction and have completed cancer treatments at least one year earlier.
GhentAges 18 years+ - NCT06339658Recruiting
Comparing two dyes for lymph node surgery in breast cancer
This trial compares two dyes (ICG and blue patent) to see which is better for finding the first lymph node (sentinel node) during surgery in women with breast cancer that has spread to the lymph nodes and who had chemotherapy first.
L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT06591039Recruiting
Breast cancer patient study in China
This study follows people diagnosed with breast cancer to learn more about the disease and treatment. It may help improve future care.
Shanghai, Shanghai MunicipalityAges Any age - NCT06598046RecruitingPhase 2
Utidelone and Capecitabine for triple-negative breast cancer brain metastases
This trial tests a combination of two chemotherapy drugs (Utidelone and Capecitabine) for people with triple-negative breast cancer that has spread to the brain. The goal is to see if the combination can shrink or control the brain tumors.
Zhengzhou, HenanAges 18 years+ - NCT06702800Recruiting
Using tumor models to predict breast cancer drug response
This study uses a personal lab-grown model of your tumor (called an organoid) to help predict which drugs are most likely to work for your specific breast cancer. It is open to both early-stage and advanced breast cancer patients who are about to start or are already receiving treatment.
Changsha, HunanAges 18–70 - NCT07169994RecruitingPhase 1/Phase 2
Testing YL202 with other cancer treatments for advanced solid tumors
This trial is testing a new drug called YL202 in combination with other anti-cancer treatments for people with advanced solid tumors that have not responded to standard therapy. The goal is to see if this combination can shrink tumors or slow their growth.
Hefei, AnhuiAges 18–75 - NCT07660055RecruitingPhase 1
Radioactive drug for advanced solid tumors
This trial tests a new radioactive drug (called 177Lu-DWJ155) that targets and kills cancer cells, along with a similar imaging agent (68Ga-DWJ155) used to see where the drug goes in the body. It is for people with certain advanced solid tumors that have not responded to standard therapies.
Omaha, NebraskaAges 18 years+ - NCT07511933Recruiting
New PET scan to detect tumor regrowth vs. scar tissue in brain
This study tests a new type of PET scan (a special imaging test) that uses a radioactive tracer to help doctors tell the difference between scar tissue from past radiation and cancer that has come back in the brain. This could help avoid unnecessary surgery or additional treatment.
AmsterdamAges Any age - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.
Tucson, ArizonaAges 18–55 - NCT06835426Recruiting
Imaging removed tissue during cancer surgery

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,470 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.
