Preventing mouth sores during breast cancer radiation
This trial tests whether a natural alginate treatment can reduce painful mouth sores and improve quality of life for women with breast cancer who are receiving radiation after surgery. If you are getting radiation to the breast area and have lymph node involvement, this treatment may help you feel better during therapy.
TaipeiAges 18 years+ - NCT06960720Recruiting
Weight lifting program for breast cancer fatigue
This trial tests whether a 3-month resistance exercise program (like lifting weights) can help reduce fatigue in women who have had breast cancer. You may be eligible if you were diagnosed with non-metastatic breast cancer 1-3 years ago and feel tired, even if only a little.
Morgantown, West VirginiaAges 18 years+ - NCT06960707RecruitingPhase 3
One vs two weeks of breast radiation after lumpectomy
This trial compares a shorter, one-week course of radiation to the standard two-week course after a lumpectomy for early-stage breast cancer. The goal is to see if one week is just as effective and safe, making treatment more convenient.
New York, New YorkAges Any age - NCT06953245Recruiting
Study of skin reactions from radiation in breast cancer patients
This study asks breast cancer patients about their skin reactions during radiation therapy. By sharing your experience, you can help doctors better understand and manage these side effects.
Rochester, MinnesotaAges 18 years+ - NCT06938581Recruiting
ERAS Recovery Steps for Breast-Conserving Surgery
This study tests a set of recovery steps called ERAS (Enhanced Recovery After Surgery) for people having breast-conserving surgery. The goal is to help you heal faster, feel more comfortable, and get back to your normal life sooner.
Omaha, NebraskaAges 19 years+ - NCT06629233Enrolling by invitation
New immunotherapy targets for estrogen-receptor positive breast cancer
This trial tests a new technique to find unique targets on breast cancer cells that could be used for future immunotherapies. It focuses on women with estrogen-receptor positive primary breast cancer.
Ghent, East-FlandersAges 18 years+ - NCT06369831RecruitingPhase 2
Imaging test for HER2 in metastatic cancer
This trial uses a special imaging scan to see if your cancer has HER2 on its surface, which could help decide if HER2-targeted treatment might work for you. It's for people with metastatic breast cancer or other solid tumors that have spread.
Innsbruck, TyrolAges 18 years+ - NCT06312176RecruitingPhase 3
Study of new drugs for HR+/HER2- advanced breast cancer
This trial tests two new drugs (sacituzumab tirumotecan and pembrolizumab) against standard treatments for a type of advanced breast cancer that is hormone receptor positive and HER2 negative. It's for people whose cancer has worsened despite hormone therapy with a CDK4/6 inhibitor.
Chandler, ArizonaAges 18 years+ - NCT05585788Recruiting
Opioid pain device test for cancer surgery patients
This study tests a device that helps you safely use opioid (strong pain) medicine after major cancer surgery. It may help improve post-surgery pain control while tracking how people use the medicine.
New York, New YorkAges 18–99 - NCT05300464Recruiting
Test MammoWave for finding breast lesions on imaging
This study checks how well MammoWave can help detect breast lesions (areas that may be abnormal) using imaging. It may help doctors confirm findings by combining it with other scans when needed, and sometimes with biopsy results.
Genova, GenovaAges 18 years+ - NCT05123482RecruitingPhase 1/Phase 2
Study of an experimental drug for advanced solid tumors

This trial tests whether radiation therapy alone is safe and effective for women 40 and older with early-stage breast cancer who have not had lymph node sampling. It aims to simplify treatment while maintaining good outcomes.
New York, New YorkAges 40 years+ - NCT06704659Recruiting
Repeated radiation for recurrent breast cancer
This study tests giving a second round of radiation therapy to women whose breast cancer has come back in the same breast, at least 3 years after their first radiation. It may be an option for women 55 and older who have a small, local recurrence that can be removed with surgery.
HelsinkiAges 55 years+ - NCT07220863Recruiting
Breast mapping test for finding suspicious spots
This trial tests a new Feminai device that maps breast tissue to find suspicious lumps. If you're coming for a routine mammogram or a biopsy, this could help improve detection.
Frisco, TexasAges 25–75 - NCT06324357RecruitingPhase 1/Phase 2

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.
