Precision radiation trial aims to better target cervical cancer

This study tested whether using MRI scans to guide internal radiation therapy (brachytherapy) is better than the standard method using X-rays for treating locally advanced cervical cancer. Over 1,000 participants with Stage IIB or IIIB cervical cancer were randomly assigned to receive either the MRI-guided or the X-ray-guided approach. The goal was to see if the more precise MRI method could improve local tumor control and reduce serious side effects to nearby organs like the bladder and rectum.
