I am new to this site, but looking for info on Kidney tumors. I am a 22 year Pheochromocytoma survivor. An 11mm tumor was seen in my left kidney on the CT scan done at Mayo Clinic on Nov 1. I go to kidney specialist on the 17th. Since my right kidney was removed in Feb of 2005, because of the Pheo, the treatment they are discussing is radiotherapy ablation? I know how it works and why they want to use it. But cannot find any info on long or short term effects on the kidney, or rate of recurrence, etc. Anyone have and info for me? Am really upset about this, the tumor was missed on last years scan, measured 7mm then. And went to Cancer Treatment Center in Zion, Ill in March, and they didn't see it either apparently! Thanks, I have not had good luck with these types of sites getting anyone to answer me or talk to me, some have even told me I could not possibly have this disease for this long!! Also, the docs do not believe the 'new' tumor has anything to do with the present disease.
