How soon after radiation therapy can they do tests to see if it's working?

My husband just finished 15 days of radiation and 3 radiation enhancing chemo treatments. How soon can they do scans to see if it is working, or if we need to change strategies?

There is no way to answer you. It would be helpful to know the type of cancer you are referring to, the stage and any other treatment that was done.
