Hi @aoifet - I can understand not wanting to alarm your sister before your biopsy. I also didn't want to worry my extended family before I had a definite diagnosis. I think one of the hard things about having anything suspicious show up on imaging is the uncertainty. For me, finally knowing one way or the other was less anxiety provoking, if that makes sense. I'm glad that you were doing your monitoring CT scans so that the nodule was caught sooner than later. That's so important, but also takes some courage, so well done.
