Baden-Baden, Baden-WurttembergAges 18 years+ - NCT03667417Recruiting
Study of people with BRCA1/BRCA2 cancer gene changes
This study follows people who carry a harmful BRCA1 or BRCA2 gene mutation, whether or not they currently have breast or ovarian cancer. The goal is to better understand cancer risk over time and how being a carrier may affect screening and care.
MarseilleAges 18 years+ - NCT07328516Enrolling by invitation
Farm childhood health study for adult children
This study looks at how early-life exposures on farms might influence long-term health. If you are an adult child of a farmer or farmworker from the Agricultural Health Study, and you spent time on a farm as a child, you may be able to join.
Bethesda, MarylandAges 18–99 - NCT07085442Recruiting
Audit of targeted lymph node biopsy for early breast cancer
This study looks at how well a special type of lymph node biopsy works for people with early breast cancer that has spread to a small number of lymph nodes. It aims to see if this approach is effective and safe, which may help guide future treatment decisions.
BurnleyAges 18 years+ - NCT03646955Recruiting
Partial breast radiation versus no radiation after lumpectomy
This trial compares giving radiation only to part of the breast versus not giving radiation at all after breast-conserving surgery. It’s meant for women with early, hormone-driven breast cancer to see if skipping radiation can be safe and reduce treatment burden.
SantiagoAges 60 years+ - NCT06830889RecruitingPhase 3
BL-M07D1 vs T-DM1 for HER2-positive breast cancer after neoadjuvant therapy
This trial tests whether a new drug called BL-M07D1 works better than an existing drug, T-DM1, for people with HER2-positive breast cancer who still have cancer cells after initial treatment (neoadjuvant therapy). The goal is to prevent the cancer from coming back.
Nanjing, JiangsuAges 18–75 - NCT05649072Recruiting
Mobile mammogram screening study for women with family cancer risk
This study looks at how well mobile mammogram units and video/phone genetics counseling (“telegenetics”) can help women who may have inherited cancer risk. If you’re scheduled for a mammogram through the Project VALET mobile units, this may be an easy option to learn about and address your risk.
