Recruiting studies
- NCT07395336RecruitingPhase 2
Elacestrant and exemestane for HR+/HER2- breast cancer that has spread
This trial tests combining elacestrant (a new hormone therapy) with exemestane (a standard hormone therapy) for people whose HR+/HER2- breast cancer has spread and who have already tried a CDK4/6 inhibitor with anastrozole or letrozole. It may help if your tumor shows certain activity on a special PET scan.
Milan, ItalyAges 18 years+ - NCT01042548Recruiting
Testing blood and tissue markers in breast surgery patients
This study looks at proteins and imaging patterns (from tissue, fluid near the tumor, and blood) to better understand breast cancer markers. It may help researchers find clues that doctors can use to evaluate breast nodules and newly diagnosed invasive breast cancer.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07469267Recruiting
Armpit radiation vs more surgery for early breast cancer with node spread
This trial tests whether radiation to the lower armpit (level I-II axilla) works as well as more extensive surgery for women with early-stage breast cancer that has spread to one or two sentinel lymph nodes (with cancer size > 2 mm). It aims to find a gentler treatment that still keeps the cancer from coming back.
Guiyang, GuizhouAges 18 years+ - NCT07557654Recruiting
Breast Cancer Detection on Chest CT Scans
This study tests whether routine chest CT scans—imaging done for other reasons—can reliably find breast cancer. Researchers will compare chest CT results with mammograms and/or breast MRI to see if this approach could catch breast cancers earlier without extra imaging.
ShanghaiAges 18 years+ - NCT05603078Recruiting
Breast cancer surgery with a tumor-bed boost and standard radiation
This study looks at whether adding extra targeted radiation to the tumor area before breast-conserving surgery, then using modern breast surgery techniques and whole-breast radiation afterward, improves outcomes for early-stage breast cancer. You may be offered a treatment plan designed to better treat the area where the tumor was removed.
Beijing, Beijing MunicipalityAges Up to 55 years - NCT01993498Recruiting
Study side effects of cancer treatment in localized breast or lung cancer
This study looks at long-term side effects from standard cancer treatments and how they affect daily life and resources. It may help improve care for people with breast or lung cancer that has not spread.
VillejuifAges 18 years+ - NCT07352137Enrolling by invitation
Endoscopic Nipple-Sparing Mastectomy with Fat Grafting for Breast Reconstruction
This trial tests a new way to remove the breast through a small cut in the armpit (endoscopic nipple-sparing mastectomy) and immediately rebuild the breast using your own fat. It's for women with early-stage breast cancer who want to keep their nipple and have reconstruction at the same time.
Guanzhou, GuangdongAges 18–70 - NCT07253987Recruiting
Cancer Survivors Program for Breast or Prostate Cancer
This study offers a program to help people who have completed their main treatment for early-stage breast or prostate cancer. It focuses on follow-up and support during survivorship, and you are still eligible if you are on certain maintenance therapies like hormone therapy.

ParisAges 18 years+ - NCT04960839Recruiting
Preventive radiation to the other breast after breast cancer surgery
This study looks at whether “preventive” radiation to your other (opposite) breast can lower the chance of future breast cancer in people at higher genetic risk. You must have had surgery for early-stage breast cancer and agree to avoid removing the other breast and ovaries.
Jiangxi, JiangxiAges 30–70 - NCT06433349Recruiting
How cancer affects family health
This study looks at how cancer affects the whole family. If you or a loved one is being treated for certain cancers with the goal of a cure, researchers want to learn how to best support families during this time.
Odense CAges 18 years+ - NCT06534918Recruiting
Nutrition and exercise help for cancer survivors
This trial tests if personalized nutrition and exercise plans improve health for people who have finished breast, prostate, or colorectal cancer treatment. It aims to help those who currently don't meet recommended activity or diet goals.
Miami, FloridaAges 18 years+ - NCT07661641RecruitingPhase 1
Study of new radioactive treatments for GRPR-positive tumors
This early-phase study tests two new radioactive treatments (lutetium-177 and actinium-225) together with a guided imaging agent in people with GRPR-positive solid tumors (including prostate, breast, or colorectal cancers). The goal is to see if these treatments can shrink tumors that have stopped responding to standard therapies.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,460 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.
