Radiation-Free path for young breast cancer patients? trial tests skipping therapy

NCT ID NCT07762924

First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time

Summary

This trial is testing whether young women under 40 with a very early, low-risk form of breast cancer called ductal carcinoma in situ (DCIS) can safely avoid radiation therapy after having breast-conserving surgery. Instead of radiation, participants will be closely monitored, and some may take hormone-blocking medication. The study will track how many women experience a recurrence in the same breast over five years to see if skipping radiation is a safe option.

What this could mean

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

Active substance
Omission of adjuvant radiotherapy, with close surveillance and optional endocrine therapy
What this could lead to
If successful, this could show that some young women with low-risk DCIS can safely skip radiation, avoiding side effects and reducing treatment burden.
What could go wrong
This is a phase II trial, so results are preliminary. Skipping radiation may increase the risk of breast cancer recurrence, and the long-term safety is not yet established.
