Exactly the same history for the last seven years but have been on sandos statin injections ever 28 days to keep the remaining lymph nodes from growing larger. In spite of this treatment, a large tumor developed in my neck ( baseball size) and had to be removed.when surgery was initially seven years ago, appendix was removed and two feet of bowel as there was a large tumor blocking. All the nodes were not able to be removed so yes, I wait also for the next eruption! It has been seven years as mentioned with only the two surgeries so I take one day at a time with constant monitoring re cat scans, bloodwork, etc. If you are worried as well you might be, be your own advocate and go get whatever tests done. Tell your GP or oncologist that you need some peace of mind! Good luck!
