Summary
This study tested whether low-level laser therapy can reduce pain and help heal sore, cracked nipples in breastfeeding women. About 96 women with painful nipple lesions were randomly assigned to receive either real laser or a placebo light treatment. The goal was to see if the laser could ease pain and speed wound healing, potentially helping mothers breastfeed longer.

- What this could lead to
- If it works, this could offer a simple, low-risk way to ease pain and speed healing for sore nipples, helping mothers breastfeed longer.
