Utility of FDG PET/CT in Patient with Synchronous Breast and Colon Cancer

A 60-year-old woman with breast invasive ductal carcinoma underwent FDG PET/CT scan for cancer staging. A synchronous colon cancer was detected incidentally. After resection of colon cancer, she received CCRT for breast cancer. Marked therapeutic response was found throughout the follow-up period. Also, there was no evidence of cancer recurrence.
