Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical research study is to compare using external beam radiotherapy with intensity modulated beams for fewer days at a higher dose per day to the same type of therapy for more days at a lower dose per day in the treatment of prostate cancer. The safety of these treatments will also be studied and compared.
