If it wasn't a surprising situation, it wouldn't have been in a medical journal.

However its possibility isn't crazy. Per https://www.ncbi.nlm.nih.gov/pmc/articles/PMC22534/ it seems that cancer cells can be detected in the blood before the cancer itself is detectable by traditional means. Therefore an undiscovered cancer could well have left circulating cells in multiple organs.
