    Whole-breast irradiation improves survival in breast cancer but poses risks to the heart and lungs, necessitating protective techniques.

  • 2

    Deep inspiration breath-hold (DIBH) and prone positioning are effective methods to reduce radiation exposure to organs at risk during treatment.

  • 3

    This study compares dosimetric outcomes of supine free-breathing, supine DIBH, and prone positioning in whole-breast irradiation.

  • 4

    The study included patients with left- and right-sided breast cancer, focusing on organ protection during radiotherapy.

  • 5

    Statistical analyses were performed to evaluate differences in radiation dose to organs at risk across the three positioning techniques.
