Summary

This study planned to test photobiomodulation (a type of light therapy) on nerve pain and sensation in one woman after mastectomy. The treatment used red and near-infrared light on the affected area for six weeks. However, the study was withdrawn before any participants enrolled, so no results are available.

What this could mean

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

Active substance
Photobiomodulation (PBM) light therapy device
What this could lead to
If it worked, this approach might point toward a non-drug way to ease nerve pain and improve sensation after mastectomy.
What could go wrong
This was a tiny case study (only one person) and was withdrawn before any participants enrolled, so we have no evidence it works. Light therapy devices also vary widely in settings, making results hard to generalize.
