What kind of prostate problems he was having for the past few months?
I guess he had a rectal digital exam and ultrasound for checking the prostate.
Do you know if he was tested for PSA levels in his blood?
This two exams( PSA and rectal digital exam ) are the basic one for early detection of prostate cancer.
Ct scan is used as an additional test to determine if cancer has spread beyond the prostate identifying abnormal lymph nodes in the pelvis and abdomen.
Ct scan is not providing good information for prostate condition or stage of cancer, so, it is useful when combined with other tests.
Are you informed that before Ct scan is performed, food and liquids must be avoided for a few hours?
