Female age 56, stage 4, diagnosed 10 yrs. ago. Runs genetically in the females of my family. Been to many different specialists including a study at Brigham/Women's, Boston. Finally found a younger MD, whom I'm relieved to progress my issues with. My question is, had a rt kidney biopsy a week ago today, she said the preliminary path came back with a lot of scarring of the tissues. Just to continue on wait and watch. I also have a complex cyst on that same kidney, that warranted an MRI but, cancelled due to lab work. What does the scarring suggest? Does that mean stage 5 or renal failure is rt. around the corner? What suggested sites should I be searching? Ty
