Radiation therapyFDA-approvedSecond-line
Radium-223
How it works
Delivers radiation directly to prostate cancer cells, killing them.
Cancer types
Prostate Cancer— All patients
Efficacy
In clinical trials, radium-223 improved survival and reduced bone complications in men with metastatic castration-resistant prostate cancer.
Side effects
Mild
Most people tolerate this treatment well. Side effects are generally manageable and do not require stopping treatment.
