CT Scan Showed Changes

Yesterday I went through CT Scan, CXR and cystoscopy.  The CXR and cystoscopy looked fine, the CT scan, however, showed a lesion on my right kidney.  This is the kidney that had the tumor 3 years ago in which the tumor plus 1/3 of the kidney was removed because of tumor location.  Looking at the CT scan the right kidney looked much larger than the left kidney. 

Because I am now going to a new facility, the doctor wants to get the actual images from my last provider before making any conclusion.  He stated that these "changes" could be from the surgery itself.  I am not believing this since it's been three years since the surgery and what drove me back to get my testing done is the pain, the same pain I experienced three years ago (and actually it's worse) prior to finding the tumor.  Also, I now have blood in my urine which I have never had before. 

I know doctors don't want to alarm their patients, but all of you know that when you have gone through this once before, you are way more educated than someone going through it for the first time.  Now I have to wait six weeks to go back so that they will have the images from my prior scans to compare against.  Meanwhile, I wait and deal with the pain. I know pain is not the usual symptom of kideny cancer, and if this lesion turns out to be another cancer I will be grateful that I had the warning again unlike so many others who did not know until it was (or almost was) too late. 

In the meantime I will try to remain positive and not worry knowing that God is in control.
