Screening for breast cancer spread after chemo and surgery
This trial aims to find out if doing special scans to check for breast cancer spread to organs (not just lymph nodes) is helpful in certain patients. The study looks at people with breast cancer that had already spread to lymph nodes and did not completely go away with chemotherapy and surgery.

Memantine and exercise to protect thinking during chemo for breast cancer
This study tests whether a medicine called memantine combined with a structured exercise program can help protect your thinking and memory during chemotherapy for breast cancer. It may also help understand how these treatments work in the body.
Chapel Hill, North CarolinaAges 18 years+ - NCT06733350RecruitingPhase 4
Testosterone therapy for low testosterone in men with low-risk prostate cancer
This study tests whether testosterone replacement therapy can safely improve low testosterone levels in men with low-risk prostate cancer who are not getting immediate treatment. It aims to help men feel better without worsening their cancer.
Buffalo, New YorkAges 18 years+ - NCT06721065Recruiting
Study of interpretation services for breast cancer patients
This study tests different ways of providing language interpretation during breast cancer or gastrointestinal cancer visits at MSK. It aims to improve communication for patients who prefer Spanish or Mandarin and have limited English proficiency.

Palma, Balearic IslandsAges Any age - NCT06635980RecruitingPhase 2
Radiation before or after breast cancer surgery

Dalpiciclib with hormone therapy for early breast cancer
This trial tests whether adding the drug dalpiciclib to standard hormone therapy improves outcomes for people with a certain type of early breast cancer (hormone receptor-positive, HER2-negative). It may help lower the risk of the cancer coming back.
