Tiny beads choke off prostate tumors in early test

This small pilot study tested a procedure called prostatic arterial embolization in 10 men with low-risk, one-sided prostate cancer who were already on active surveillance. The idea was to block the artery feeding the tumor, starving it of blood. Researchers checked for side effects and whether cancer cells remained in the treated area. The goal was local control, not a cure, and patients may still need other treatments later.
