What this Trial Is About

This study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)?
