      This will depend largely on the cancer and goals of treatment (curative vs. palliative). In most cases, a follow-up scan (CT, PET, etc.) will be utilized to assess efficacy of radiation. Sometimes one may rely on bloodwork for this purpose (e.g., PSA in prostate cancer) In other cases (e.g., radiation to the breast after curative surgery) there is no way to evaluate efficacy - only time will tell if the treatment was effective in preventing relapse. Hope that helps !
