First seen Mar 13, 2026 · Last updated May 16, 2026 · Updated 9 times

Summary

This study looked at oxygen levels inside prostate tumors in 186 men with early-stage prostate cancer. Researchers used a special needle through the rectum to measure oxygen before starting radiation or hormone therapy. The goal was to see if low oxygen levels make treatment less effective and lead to cancer spread. The study did not test a new treatment but aimed to gather information to improve future therapies.
