Summary

This completed study tested a special dye called TTP-ICG that sticks to breast cancer cells. After removing tissue, doctors soaked it in the dye and used a special camera to see if cancer cells were left at the edges or in lymph nodes. The goal was to help surgeons know right away if they got all the cancer out, reducing the need for second surgeries. The study involved 59 women with breast lumps.

What this could mean

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

Active substance: TTP-ICG (a dye that sticks to cancer cells)
What this could lead to: If successful, this could give surgeons a quick, accurate way to check during surgery whether all cancer has been removed and if lymph nodes are affected, potentially reducing repeat surgeries.
What could go wrong: This was a small, completed study with 59 people, so results may not apply to everyone. The dye's accuracy in real-time surgery still needs more testing.
