|Prostate Cancer||Other: Plasma Blood collection|
Currently, a patient's risk for toxicity is based almost exclusively on population statistics. Radiation (and chemotherapy) dose are based on phase I data and not on the individual's specific genetics or hidden predispositions. RadTox measures cell damage within 24 hours of radiation exposure and should help identify patients at higher risk for radiation complications. This should allow physicians to adjust radiation field size and dose to minimize long-term toxicity.
Patients undergoing radiation treatment for stage I to III prostate cancer, using protons or X-rays, either as primary treatment or consolidation after prostatectomy (positive margins or prostate-specific assay [PSA]-related indications) will be eligible. Hormone treatment will be allowed.

Evaluate toxicity biomarkers
Investigators will determine if measurement of circulating DNA from tumor and normal tissues shortly after RT provides an early and quantitative measure of risk of radiation-related complications. It will be necessary to collect blood specimens prior to and during the first week of radiation therapy.
Other: Plasma Blood collection
Plasma blood collection is collected at specific intervals prior to and during radiation treatment.
