Last March I has my left kidney removed because of Renal Cancer. We thought that we had gotten everything (kidney and surrounding area plus a lymph node. After 3 months I had another cat scan and there was a new node in my right lung and another one in my right which was old and one more in my left lung. It was biopsied but not enough to get a conclusive results. So we wait another 3 months and we go through the same process and find that the new one in my right lung is renal cancer. So in January I had open chest surgery and they remove all the nodes and find another one and it was removed also. Now I wait until the end of April for another cat scan. Cancer seems to me a surgery wait 3 month for a cat scan to see if you have anything new. Then the testing process and maybe another surgery and so on. Is this the normal happening when they detect cancer in you?
