Yes, why aren't they doing a CT or PET scan? And no, what you are outlining is highly unusual. Typically, you go back to doctors on a regular basis post surgery and radiation and their visual examination is enough. Pictures via CT and PET come months later unless they have an issue and if so they should certainly be telling you what their concerns are. Good luck.
