Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Exposure to radiation can impact immune cells that are present in the blood, such as lymphocytes. It is hypothesized that larger radiation fields and/or longer courses of radiation, result in greater decrease in immune cells. To test this hypothesis, investigators will take blood samples from subjects undergoing two different standard of care radiation regimens for prostate cancer, and subjects undergoing two different standard of care regimens for breast cancer.
