Brachytherapy uses radioactive seeds, about the size of a grain of rice, stranded on a synthetic filament and implanted in the prostate gland. The seeds emit a low level radiation that destroys cancer cells while preserving healthy tissue.

In spring 2005, the Arnold Palmer Prostate Center at Eisenhower Lucy Curci Cancer Center will be the first facility on the West Coast utilizing the IsoStrand® technology, which provides immediate, on-site creation of the stranded radioactive seeds, reducing the typical two-week waiting time to days to complete the treatment.
