Radioactive "Seeds"

How Low-dose-rate Brachytherapy (LDR) Works

LDR brachytherapy, which includes prostate seed implantation, is a procedure that places rice-sized radioactive "seeds" into the cancerous tumor. Seeds can be left in place permanently, as they give off radiation only for a specific period of time, from a few weeks to several months, and do not need to be removed once the radiation is depleted. It’s important to note that there are a few limited restrictions regarding contact with pregnant women and children for patients during this "radioactive" period, but most regular activities can be resumed upon release from the hospital.

Permanent seed implants, given either alone or in combination with external-beam radiation therapy as an alternative to surgery, are one of the most popular radiation procedures in the United States due to their high success rate and limited side effects when used for localized tumors such as prostate cancer.
