Summary

This trial tests whether a 12-week slow jogging program can help breast cancer survivors sleep better, feel less tired, and enjoy a better quality of life. Women who have finished primary treatment for hormone receptor-positive breast cancer will either jog slowly three times a week or continue with their usual care. Researchers will track sleep quality, fatigue, and overall well-being over three months to see if this gentle exercise makes a difference.

What this could mean

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

Active substance
Slow jogging exercise program
What this could lead to
If effective, slow jogging could become a simple, accessible way to improve sleep and reduce fatigue in breast cancer survivors.
What could go wrong
This is a relatively small, early-stage trial, and results may not apply to all survivors. The benefits of slow jogging are not yet proven, and some participants may find it hard to stick with the program.
