How many years it takes for a head CT with and without contrast to find a tiny brain tumor?

Depends. It depends on the type of tumor and it's location- it also depends on size of the tumor. If the tumor enhances when you add contrast, it's easier to see after it grows to just a few millimeters. Some tumors which grow slowly are undetected because no one does a scan- but the scan would have shown it if one was done.
