Summary

This completed study involved 775 women who had breast-conserving surgery and radiation for breast cancer. Researchers compared different surgery and radiation techniques to see which ones led to less breast hardening (fibrosis) and better cosmetic results. The goal was to find ways to improve how the breast looks and feels after treatment, helping women feel better about their appearance and quality of life.
