My total protein had been increasing, so my dr had me test for multiple myeloma. protein had come down to normal,no m-spike observed, everything normal except a slightly elevated kappa of 21.5 in serum (but normal in urine). could i still have cancer?

Cancer: Rarely multiple myeloma can be present with normal serum electrophoresis but immunofixation may show it. Your free light chain assay showed what you say is a slightly elevated kappa level of 21.5/L, but I note that up to 26.3 is normal. The bottom line is, if you have no suspicious symptoms, I would be reassured. If there are symptoms, bone marrow biopsy would be done. Your MD is best to advise yo
