CAT Scan (CT - Computerized Tomography)

There are a variety of physician preferences for following tumors during therapy, but the approach used in most clinical trials is a standard CT scan every other cycle of chemotherapy. There is increasing use of PET scanning, but this is experimental, expensive, and there is a high risk of getting misleading information from a PET that could result in inappropriate changes in therapy.

I also had it about a week after the sentinel lymph node biopsy was positive with cancer.
