In brief: It does happen

Many tumors, especially without noticeable symptoms, are diagnosed following metastasis.
Depending upon how the tumor appears under the microscope, a pathologist can often point out precisely where it came from, or, usually, a likely region. From there, it is a group effort, often involving pathologists, radiologists, and, in this case a gastroenterologist or general surgeon.

In brief: Not common.

It is not common but it does occur. Sometimes, the primary source is undetectable by imaging studies/endoscopies.
Some think that the primary site was 'killed' by the immune system, while the cells that spread are different. They act differently, more aggressively.
