Visit update:, in spite of the kidney lesion growing a centimeter and a half since my last MRI, they just still want to watch it. It's now about 6cm and too large for ablation and probably biopsy, which wasn't exactly what I had hoped to hear. It is still considered a Bosniak 2f lesion until imaging shows otherwise, so it looks like I'm stuck with the little bugger for now. I will also be doing a GI consult because I have a complex cyst on my liver that will be looked into a little further, so I'm waiting to hear from them about that appointment. Thanks for all the encouragement and helpful responses, this is a wonderful group.
