@rangerop6 Inadvertently, some years ago, my urologist found a cyst on my right kidney that turned out to be cancerous. My urologist wanted me to see an interventional radiologist, and he later performed cryoblation on the affected kidney, that is, he froze the cancerous mass causing it to dissipate and never to return after 5 years of annual x rays. This procedure was done as an outpatient at my hospital so I went home shortly after. I have told this story before on this forum, and another patient had the same procedure done so she didn't have to wait months to see another specialist for additional testing. This was an option for me, and it worked out very well. Check with your doc to see if he/she feels this is an alternative as well. This procedure was pain free and from what I read years ago 90%+ successful.
