NCT ID NCT02743858
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows 1,250 women who have had lymph node removal during breast cancer surgery. Researchers use arm measurements and tissue tests to see who develops lymphedema (arm swelling) and why. The goal is to find early warning signs and improve quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors predict and catch lymphedema earlier, improving quality of life for breast cancer survivors.
- What could go wrong
- This is an observational study, not testing a new treatment. It may not lead to direct changes in care, and results depend on many individual factors.
This is an AI summary of the original study and may miss details. Read our disclaimer.
