If your doctors have checked for cancer in your remaining kidney and it was normal, provided you do not have a history of kidney cancer in your family, it is unlikely you will develop cancer in your remaining kidney.

Only about 3 out of every 100 people with kidney cancer develop cancer in both kidneys. This is most likely to be found when the cancer is first diagnosed. It is also more common in people with a history of kidney cancer in their family. But it is unlikely to develop later on if only one kidney is affected when you are first diagnosed. So the chances of developing cancer in your other kidney are small.
