New precision radiation aims to zap prostate tumors while sparing healthy tissue

This early-phase study tests a new way to deliver radiation implants (brachytherapy) for men with localized prostate cancer. By using advanced imaging (PET/CT and ultrasound) to map only the aggressive tumor areas, doctors hope to target the cancer while leaving healthy tissue untouched, potentially reducing side effects. The study enrolls 20 men with low- to intermediate-risk prostate cancer to see if this focused approach can effectively cover the tumor.
