Thank you for sharing, this is helpful.
Could you please share what Grade was your prostrate cancer and if you had surgery to remove it or you took the radiation path? Also, was the kidney cancer found via a CT scan? seems it wasn't surgically removed either and you just received radiation as a treatment for it, was that the case?
The cases of concurrent cancer that i have read about on the internet have led to one time surgery of removal of the prostrate and kidney (partial or total as needed).
In my husband's case, the Doc ordered a bone scan and a CT scan, the abnormality in the kidney showed up in the CT scan. As mentioned earlier we are going to see the surgeon to discuss treatment options day after tomorrow, we have yet to discuss the Kidney abnormality with them.
