Summary

This study tests a simpler way to check for cancer spread after chemotherapy in women with node-positive breast cancer. Doctors will use a blue dye called methylene blue to find and remove a wider area of lymph nodes, instead of the standard method. The goal is to see if this approach is safe and reduces the risk of arm swelling (lymphedema) after surgery. About 240 women will take part, and they will be followed for two years.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: methylene blue
What this could lead to: If successful, this could simplify breast cancer surgery by safely using a less invasive lymph node removal technique, potentially reducing arm swelling after treatment.
What could go wrong: This is an early-stage study with no control group, so results may not apply to all patients. The dye method may miss cancer cells, leading to false negatives.
