This trial tests whether proton therapy, a more precise form of radiation, causes fewer long-term bowel side effects than standard photon therapy in men with high-risk prostate cancer. Participants receive the same radiation dose and schedule, but one group gets protons and the o…

This phase 3 trial compares a new, shorter course of radiation (ultra-hypofractionated) to the standard longer course for men with prostate cancer that has spread to lymph nodes. Both groups also receive a brachytherapy boost and hormone therapy. The study aims to see if the shor…

This study follows breast cancer patients who have had curative surgery and are receiving hypofractionated radiation therapy—shorter treatment courses lasting one to three weeks. Researchers will track changes in breast skin, fibrosis, cosmetic appearance, and patient-reported ou…
