I had a PET scan. it showed uptake in the right groin lymph node is 6.7 compared to previously at 1.8. with multiple lymph nodes. the largest is 1.2 cm compared to 2.7 cm.THe right external iliac Lymph node is 1.1 cm compared to 2.7cm. I was diagnosed with Follicular NHL in May 2012, stage 2. I have never been treated. Last PET scan was dec 2016. Every year the scans showed improvement. THis one last week, showed the above values. Originally, there were only 2 nodes on the right and 2 on the left. A large one was removed from the right in 2012 for biopsy. All other tests have been normal(I haven't had my bloodwork done yet for this one, though). I do have arthritis in the right femoral head and torn cartilage in the right hip, which has been bothering me for 6-8 weeks off and on. ALso, I can feel the pea size bumps in my groin, that are somewhat painful when pushed on. What do you think?
