Study Summary

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.

Primary Outcome

prospectively collect collect physical and dosimetric information of treatment and sequential blood samples for assessment of peripheral immune mediators in 4 distinct clinical settings of standard radiotherapy (2 for breast and 2 for prostate cancer)
