Behind the Scenes: Why Cesium-131 Brachytherapy for Prostate Cancer?

Rapid resolution of side effects, more living life. Hear from two survivors and radiation oncologist Dr. Alex Hsi, MD, about the importance of knowing all of your treatment options including Cesium-131 brachytherapy.

With more than 250,000 new cases every year, prostate cancer is second in prevalence only to skin cancer among American men.

“Before making a treatment decision, I think it is vitally important that a man discuss his treatment options with multiple physicians including a urologist and radiologist who specializes in prostate cancer treatment,” says radiation oncologist Dr. Alex Hsi, MD.

Prostate cancer treatment options include radical prostatectomy (removal of the prostate), radiation therapy, brachytherapy and cryotherapy. With so many options and so many different stages and types of prostate cancer, getting educated on success rates and post-treatment impacts on quality of life is perhaps the most important action newly diagnosed men can take.

In this “Behind the Scenes” video, learn about interstitial brachytherapy, a cancer treatment that delivers high levels of ionizing radiation to a specific area while limiting the dose to the surrounding healthy tissue and critical structures. More specifically, learn about the advantages that Cesium-131 brachytherapy has over other isotopes like Iodine and Palladium also used for prostate cancer brachytherapy treatment.


Because of its strong survival rates, over 10,000 men have chosen Isoray’s Cesium-131 brachytherapy as a cost-effective, minimally invasive way to treat their prostate cancer and return to normal activity and a strong quality of life.

“I would recommend that anyone diagnosed examine brachytherapy because of the study results I have observed,” says prostate cancer survivor Jim Menzies, PhD. “The best part is that I have a very active life and the restrictions that a lot of people that I know of that had prostate surgery, I don’t have those symptoms for the most part.”
