Recruiting studies
- NCT07677839Recruiting
Study using ultrasound to look at normal lymph nodes before breast surgery
This study uses a special type of ultrasound (UHFUS) to take detailed images of your lymph nodes before and during breast cancer surgery. The goal is to better understand normal lymph node anatomy, which may help prevent lymphedema (swelling) after surgery.
Sacramento, CaliforniaAges 18 years+ - NCT07528638Recruiting
Nerve monitoring during breast cancer lymph node surgery
This study tests whether special nerve-monitoring equipment and a specific type of surgical tool can reduce nerve damage during lymph node removal surgery for breast cancer. Researchers want to see if these techniques help preserve arm and shoulder function after surgery.
Cincinnati, OhioAges 18–70 - NCT07351487RecruitingPhase 2
Chemo plus immunotherapy and anti-angiogenic drug for TNBC before surgery
This trial tests whether adding sintilimab (an immunotherapy) and bevacizumab (a drug that blocks blood supply to tumors) to standard chemotherapy before surgery can improve outcomes for women with stage II or III triple-negative breast cancer. It may help your immune system fight the cancer more effectively.
HefeiAges 18–75 - NCT07362485Recruiting
Finding sentinel nodes during mastectomy with dye
This trial tests if a special dye (indocyanine green) can find the first lymph nodes (sentinel nodes) during mastectomy. It may help improve staging for women with early breast cancer who need or choose mastectomy.
Zwolle, OverijsselAges 18 years+ - NCT07362914RecruitingPhase 3
Steroid cream for hand-foot skin reactions from chemo
This trial tests whether a corticosteroid cream can prevent or reduce hand-foot skin reactions caused by liposomal doxorubicin (a type of chemotherapy) in breast cancer patients. If you are starting this chemo and are concerned about skin side effects, this study may offer a way to manage them.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07369505RecruitingPhase 1
A study of Sapu003 for advanced tumors sensitive to mTOR
This trial tests a new drug, Sapu003, in people with certain advanced cancers that may respond to mTOR-targeted therapy. It is looking at two groups: postmenopausal women with a type of breast cancer (HR+/HER2-), and adults with kidney, liver, neuroendocrine, or TSC-related tumors. The goal is to see if Sapu003 is safe and effective.
AdelaideAges 18 years+ - NCT07378306RecruitingPhase 2
Fasting-mimicking diet with chemo-immunotherapy for triple-negative breast cancer
This trial tests whether adding a special low-calorie diet (called a fasting-mimicking diet) to standard chemotherapy and immunotherapy can help treat triple-negative breast cancer before surgery. It aims to see if this combination makes the treatment work better.
Guangzhou, GuangdongAges 18–70 - NCT07394218RecruitingPhase 2
Tumor DNA Blood Test to Guide Breast Cancer Treatment
This trial tests whether using a blood test for tumor DNA can help doctors decide the best treatment for people with HER2-negative breast cancer that has spread. It focuses on a type of therapy called an antibody-drug conjugate (ADC) and aims to personalize your care.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT03357120Recruiting
Using blood DNA to assess response after breast cancer chemotherapy
This study checks whether a blood test that looks for “tumor DNA” (circulating tumor DNA) can help evaluate how well neoadjuvant chemotherapy worked for breast cancer. It may help doctors better understand treatment response after surgery.
BordeauxAges 18 years+ - NCT03321045RecruitingEarly Phase 1
PET scan to predict benefit from HER2-targeted breast cancer therapy
This early-phase study uses a special PET scan with a drug tagged for imaging to predict how well HER2-targeted treatments will work. It may help doctors choose the most effective therapy for HER2-positive breast cancer.
Birmingham, AlabamaAges 18 years+ - NCT06507618RecruitingPhase 3
Pre-surgery hormone therapy to guide radiation decisions for breast cancer
This trial tests whether taking hormone therapy for 3 months before breast-conserving surgery can help doctors decide if radiation is right for you. It is for women aged 65 and older with a common type of breast cancer that is hormone receptor-positive and HER2-negative.
New Haven, ConnecticutAges 65 years+ - NCT07426809Recruiting
A study to improve lumpectomy surgery with real-time imaging
This study tests a new imaging tool that helps surgeons see cancer margins in real time during a lumpectomy, aiming to reduce the need for a second surgery. It is for women with early-stage breast cancer who are planning a lumpectomy.
Beaumont, DublinAges 18 years+ - NCT07446868Recruiting
Comparing two nerve blocks for pain after mastectomy
This trial compares two nerve-block techniques (SPSIP and ESPB) to see which one provides better pain relief after breast cancer surgery. The goal is to reduce pain and improve recovery after a modified radical mastectomy.
Cairo, Cairo GovernorateAges 18–65 - NCT07447440Recruiting
Study on natural fats linked to obesity-related diseases
This trial explores how certain natural fats in the body might affect diseases linked to obesity, such as breast cancer. It aims to see if these fats can reduce inflammation and improve health.
Pamplona, NavarreAges Any age - NCT07448558Recruiting
Tailored exercise for breast cancer joint pain
This trial tests if a personalized exercise program can reduce joint and muscle pain caused by aromatase inhibitors in breast cancer patients. It may help you feel better during your hormone therapy.
BangkokAges 18 years+ - NCT07455955RecruitingPhase 2
Custom anti-nausea treatment based on your genes
This trial tests if giving anti-nausea drugs based on your genetic makeup can better prevent vomiting and nausea from chemotherapy for early breast cancer. You will receive a personalized regimen tailored to your pharmacogenetic profile.
Hong KongAges 18–74 - NCT07464457Recruiting
Prehabilitation before cancer treatment
This study tests whether exercise and support before cancer surgery or radiation can improve recovery. It is for adults with solid tumors, especially breast cancer, who are scheduled for curative treatment.
Münster, North Rhine-WestphaliaAges 18–65 - NCT07474337Recruiting

This trial tests whether a nutritional supplement called sulforaphane (SFN) can help protect heart function in people with breast cancer who are receiving doxorubicin (a chemotherapy that can affect the heart). Participants take caplets and have heart and safety monitoring to see if the supplement reduces heart-related side effects.
Lubbock, TexasAges 18–89 - NCT07498855Recruiting

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,466 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.
