Why Prostate Seed Implant?

Brachytherapy for prostate cancer is also known as Prostate Seed Implantation (PSI).  Brachytherapy is an innovative cancer treatment that places radiation sources or seeds directly inside the prostate allowing for a highly targeted treatment dose to be delivered while limiting dose to surrounding critical organs. The data clearly shows that in well-selected patients that Prostate Seed Implantation (PSI) is an ideal treatment option that maximizes cure rates while limiting side effects.

SURVIVOR | Lou Lotorto

Lou was diagnosed with prostate cancer in 2007. After investigating all of his options, Lou eventually chose brachytherapy.

“I never had a day when I had a regret I might have chosen the right course. We all have our second thoughts, I had none. It was a smooth operation all the way including my recovery. In essence, I never had any time I was laid up or brought down. I kept my normal, busy schedule. I never felt like my energy was flagging or that I made a wrong choice.”


Simply stated, the data consistently shows that for low, intermediate, and high risk prostate cancer the cure rates for prostate seed implant are comparable or better to any other treatment option.
