In brief: Sometimes.

It depends on many factors, the size of the cancer, the organ it involves, technical factors with the study, etc.
There are many variables. Remember each cancer starts as a single cell, so we can never completely exclude the diagnosis even when a ct is completely normal. Pet/ct can show cancers that are virtually impossible to see on ct, even with contrast.

In brief: Yes, but

Yes it can, but not always, and not all kinds of cancer.
There are many variables: whether or not IV contrast is used, whether or not oral contrast is used, the timing of the scan after contrast, etc. A radiologist can tailor the scan to look for certain tumors if they know what kind you are looking for. But an obvious tumor is usually visible on most ct scans.
