A few years ago I tossed a kidney stone painlessly. When I told my doc she sent me for a CAT scan to determine if I had any other stones lurking around. The scan didn’t disclose any more stones but it did show that a couple of lymph nodes were somewhat enlarged. After monitoring them with a bunch of scans the oncologist let me cut back to an annual scan to check them. Had my scan this morning. Will see the oncologist on March 7th.
