Recruiting studies
- NCT00899301Recruiting

Winston-Salem, North CarolinaAges 18–85 - NCT07478900Recruiting
Tattoo marking breast tumors before chemo
This trial tests a simple method: marking the tumor with a small tattoo before chemotherapy. The tattoo helps surgeons find the exact spot for lumpectomy after the tumor shrinks, so you can keep more of your breast.
Bhubaneswar, OdishaAges 18–75 - NCT07483307RecruitingPhase 2
Hormone therapy before surgery for lobular breast cancer
This trial tests whether taking hormone therapy before surgery can improve outcomes for women with a specific type of breast cancer called lobular breast cancer. If you qualify, you would receive endocrine therapy for 6 months before your planned breast-conserving surgery.
Basking Ridge, New JerseyAges 50 years+ - NCT07484087Recruiting
Ablation vs. Surgery for Early Breast Cancer
This trial compares a less invasive treatment called ablation (which uses extreme cold to destroy the tumor) with standard surgery for early-stage breast cancer. It is for women aged 50 or older with a small, low-risk tumor that has not spread.
Beijing, Beijing MunicipalityAges 50 years+ - NCT07492394RecruitingPhase 2
Testing dalpiciclib with or without entinostat and letrozole for early breast cancer
This trial is testing a combination of three drugs (dalpiciclib, entinostat, and letrozole) for women with early-stage, hormone-receptor-positive, HER2-negative breast cancer. It aims to see if adding these medications before surgery can help shrink the tumor.
Shijiazhuang, HebeiAges 18–75 - NCT07503496Recruiting
Biobran supplement for breast cancer chemo support
This trial tests if a supplement called Biobran (made from rice bran) can help support people with breast cancer who are receiving chemotherapy. It may reduce side effects or improve treatment tolerance.
TaichungAges 20–65 - NCT07507890Recruiting
Nipple-sparing mastectomy through one armpit incision
This trial tests a less invasive surgery for early-stage breast cancer that removes breast tissue through a single small cut in the armpit while keeping the nipple. It may be an option for women with small to medium breasts who are candidates for immediate breast reconstruction.
Candiolo, TurinAges 18 years+ - NCT07539038Recruiting
Exercise Program for Early-Stage Hormone-Positive Breast Cancer
This study tests whether a structured exercise program helps women with early-stage hormone-positive breast cancer who are taking endocrine therapy (hormone-blocking medications). The goal is to see if physical activity improves outcomes and quality of life during treatment.
Aviano, PordenoneAges 18 years+ - NCT07555210Recruiting
Bone Density Changes During Cancer Immunotherapy
This study tracks how a type of cancer treatment called anti-PD-1 immunotherapy affects bone strength over time. Researchers want to understand whether this treatment causes bone density loss and help develop ways to protect bones during cancer care.
Nashville, TennesseeAges 18 years+ - NCT07574671Recruiting
Ketogenic Diet Study for Early-Stage Breast Cancer
This study tests whether a ketogenic diet (high fat, low carb) can help change the environment around breast cancer tumors in ways that might slow cancer growth. You'll follow the diet for several months while researchers monitor your health and take measurements.
San Antonio, TexasAges 18 years+ - NCT07579286Recruiting
Skipping lymph node surgery in early breast cancer
This trial tests whether older women with early-stage, slow-growing breast cancer can safely skip removal of underarm lymph nodes during surgery. The goal is to reduce surgery-related side effects while maintaining safety.

Testing INV-6452 for advanced breast cancer and solid tumors
This study tests a new drug called INV-6452 to see if it is safe and can help control advanced cancers that have grown despite prior treatment. The drug targets specific cancer cell weaknesses, particularly in hormone-sensitive breast cancers without HER2 mutations.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07615751RecruitingPhase 3
New drug combination for advanced HER2-positive breast cancer
This trial tests whether a newer drug called dalpiciclib works better than chemotherapy when combined with two other anti-HER2 drugs (pyrotinib and trastuzumab) for advanced breast cancer that has spread. The goal is to find a treatment that works well with fewer side effects.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07631052RecruitingPhase 2
Low-dose Capecitabine for High-risk Early Breast Cancer
This study tests whether a low-dose chemotherapy pill called capecitabine can help prevent breast cancer from coming back in patients whose cancer shows signs of remaining disease (called MRD) despite standard treatment. The trial focuses on hormone-receptor-positive, HER2-negative breast cancers.
Toronto, OntarioAges 18 years+ - NCT07635147Recruiting
