DragonsPark,
Have they classified your cancer type? I became aware of mine in a routine chest ct and since it was tiny and not very impressive we just watched it every year for four years. This year it grew a bit though was still less than 1.5cm. But surgery to remove it 4.5 mos ago revealed it was Adenocarcinoma 1a. So they took my left lower lobe and a bunch of lymph nodes which tested negative. Clearly my cancer type grew slowly. That doesn’t mean yours would but if the hot node in question was only revealed to you in patient portal, I would definitely call my doc for clarification.
