Recruiting studies
- NCT06719206Recruiting
Reducing sitting time during cancer treatment
This study looks at helping people with breast, prostate, or colorectal cancer who are starting or have recently started treatment (like chemo or radiation) to sit less and move more during their treatment. If you are treated at a hospital in Uppsala or Västerås, Sweden, you may be able to join.
UppsalaAges 18 years+ - NCT04109079Recruiting
Best surgery plan for breast cancer lymph nodes after chemotherapy
This study looks at the safest and most useful way to remove and check breast-cancer lymph nodes in the armpit after you finish chemotherapy given before surgery. It may help you avoid unnecessary surgery while still getting accurate information about how well the treatment worked.
DublinAges 18 years+ - NCT06266026Recruiting
AI-enhanced thermal imaging for breast cancer screening
This study tests a new, non-contact thermal camera (thermography) combined with artificial intelligence to find breast cancer. It is designed for women coming for routine screening, high-risk screening, or diagnostic exams, and aims to see if this painless, radiation-free method can help detect cancer earlier.
HeidelbergAges 18 years+ - NCT05438511Recruiting
Improve breast cancer hormone test practices in Tanzania
This study evaluates how to improve testing of hormone receptors (which helps guide breast cancer treatment) in Tanzania. It uses interviews or focus groups with breast cancer survivors, advocates, and healthcare workers, plus reviews of existing medical records.
New York, New YorkAges 18 years+ - NCT07558447Recruiting
Studying Tiny Particles to Predict Chemotherapy Nerve Damage
This study looks at tiny particles in your blood to understand and potentially predict nerve damage caused by certain chemotherapy drugs. Researchers will monitor you before, during, and after your cancer treatment to see if these particles can help warn doctors about this common side effect.
MilanAges 18 years+ - NCT07546695Recruiting
Axillary lymph node surgery choices for HER2+ and triple-negative breast cancer
This study examines the best surgical approach for removing underarm lymph nodes in patients with HER2-positive or triple-negative breast cancer who have received chemotherapy before surgery and still have cancer in their lymph nodes. The goal is to understand whether removing more lymph nodes improves outcomes for these patients.
BaselAges Any age - NCT06555614Recruiting
Safety of a special mesh in breast reconstruction
This study tests if a special mesh called an acellular dermal matrix (SC DERM® Recon) is safe for women having breast reconstruction with implants after mastectomy for breast cancer. It involves careful follow-up to check for any problems.
Seoul, SeoulAges 19–79 - NCT06193369Recruiting
Digital peer support for young adults with cancer
This trial connects you with a trained peer (someone who has been through cancer) who provides support and guidance online. It's for young adults who finished treatment for certain cancers in the past year.
Toronto, OntarioAges 18–40 - NCT06908668RecruitingPhase 2
Adebrelimab plus chemo with or without radiation before breast cancer surgery
This trial tests adding a drug called adebrelimab to standard chemotherapy and possibly radiation, given before surgery for breast cancer that is HER2-negative and locally advanced. The goal is to see if this combination helps shrink tumors more effectively, potentially allowing for breast-conserving surgery.
BeijingAges 18–70 - NCT06765252Recruiting
How gene differences affect capecitabine side effects
This study looks at how genetic differences in Egyptian people with breast or colorectal cancer might affect the side effects of the chemotherapy drug capecitabine. The goal is to understand why some people have more side effects than others.
Shibīn al Kawm, MenoufiaAges 18 years+ - NCT07449273Recruiting
Breathing exercises after breast surgery
This study tests breathing exercises to help you recover after breast surgery. It may improve your breathing and comfort during recovery.
Istanbul, IstanbulAges 18 years+ - NCT05062707Recruiting
Study of early aging in young people during cancer treatment
This study looks at how “early aging” changes show up during treatment in young adults with cancer. It may help doctors better understand health effects during curative therapy and improve care for people your age.
GroningenAges 18–39 - NCT06839001RecruitingPhase 3
Freezing small breast tumors instead of surgery trial
This study tests if freezing a very small early-stage breast tumor (cryoablation) can be as effective as surgery. It may be an option for people whose tumor is small enough and hasn't spread to lymph nodes or elsewhere.
São Paulo, São PauloAges 18 years+ - NCT01521741Recruiting
Breast cancer lymphedema screening to detect early swelling
This trial looks at whether scheduled measurements can spot early swelling (lymphedema) in people with breast cancer. It may help find problems sooner so treatment or prevention steps can start earlier.
Boston, MassachusettsAges 18 years+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Birmingham, AlabamaAges Any age - NCT04687956Recruiting
Preventing arm swelling after breast cancer lymph node surgery
This study looks at ways to prevent arm swelling (lymphedema) related to breast cancer after surgery to remove lymph nodes. It may help people who are getting axillary lymph node dissection lower the chance of long-term swelling.
SeoulAges 19 years+ - NCT07685938RecruitingPhase 2
Medicines to prevent heart damage from radiation
This trial tests whether common heart medicines (statins or ACE-inhibitors) can protect the heart during cancer radiation therapy. It is for adults who are about to start chest radiation and have not taken these drugs before.
Chapel Hill, North CarolinaAges 18 years+ - NCT06713161Recruiting
New dye to spot breast cancer during surgery
This study tests a special dye that helps surgeons see breast cancer tissue and nearby lymph nodes more clearly during surgery. The goal is to make sure all cancer is removed while sparing healthy tissue.
Kunming, YunnanAges 18–75 - NCT04750122RecruitingPhase 1/Phase 2
Drug-screening guided treatment before surgery for HER2 breast cancer
This trial tests a treatment plan that is chosen using drug-testing in a lab (to see which medicines may work best) before surgery. It is for people with early-stage HER2-positive breast cancer, aiming to improve outcomes by guiding the right treatment early.
Beijing, Beijing MunicipalityAges 18–75 - NCT05032768Recruiting
Study links between skin bacteria and radiation skin reactions
This study looks at how changes in the skin’s normal bacteria (microbiome) relate to getting redness, irritation, or rash after breast radiation. It may help doctors predict who is more likely to have skin side effects after reconstruction and radiation.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05916755Recruiting
Testing tumor clues that predict response to immunotherapy
This study looks for “biomarkers,” or tumor clues, that may help predict who benefits from checkpoint inhibitor immunotherapy in triple-negative breast cancer. It may help doctors choose the right treatment approach in the future, especially when chemotherapy is planned.

Treatment options for breast cancer that has spread to the liver
This study looks at how breast cancer that has spread to the liver responds to different treatments, including surgery and medicines. The goal is to learn which approach works best for patients with this condition.

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.
