When I first went to the doctor my lymph node had been enlarged for over a year (or even more 😳) but I still felt good. I was diagnosed with stage 3 (FL) and sent to chemo. So you better see your doctor and check.

You need a biopsy on new nodes to check if lymphoma transitioned to a more aggressive form such as a higher grade (I assume your low grade 1-2) or diffuse B cell. If it remains a low grade, they usually recommend treatment if you become symptomatic, having complications and if nodes are over a certain size. Always get a 2nd opinion. Recently was treated with Bendamustine & Gazyva (immunotherapy, had Rituximab in the past) and in remission once again! You may only need to be treated with immunotherapy/Rituximab).
