Narrator: This is Science Today. By the year 2000, at least one third of prostate cancer patients may be treated with radiation seed therapy. Dr. Mack Roach of the University of California, San Francisco says high tech equipment and hormonal supplements have enhanced this century old therapy in which radioactive pellets are placed at the site of the tumor.
Roach: We have been doing seed implants here for just over a year, so we don't have long term follow-up information at this institution. We have gone back to look at the quality of our implants and we believe that we have very high quality implants.
Narrator: While this outpatient procedure does improve quality of life, Roach stresses at this point, it's just another option.
Roach: I am not suggesting that no man should have a radical prostatectomy. I think that there's still some unresolved questions. We need longer follow-up. This is another option and that it's important for a man to know all of his options before he makes a decision.
