Hi there and apologies if this is in the wrong place.
DF had an ultrasound recently where they discovered a cyst (this is definitely the word that they used for it) on one of his kidneys. It's quite large, and causing DF some discomfort.
He's waiting to see the urologist about it, and there's been talk of an MRI to further examine it.
Anyone have any experience with masses on kidneys? It doesn't sound all that benign to me, but I don't know, maybe DF is telling me it's just a cyst so that I don't worry about him.
