my husband had renal carcinoma 2 years ago and they removed his left kidney - the tumor was very large and some entered the renal vein.  All has been well so far, however, his last checkup showed a shadow on his lung exray - the hospital just called and his original oncologist wants to see him re followup to this new development on Monday - can you tell me what to expect  My husband is 55 years old and weighs 165 pounds, 6 feet tall
Based on your description, your husband had a non-metastatic left renal carcinoma for which he underwent radical surgery. I assume that the x-ray done at the time of surgery was normal. However, it is quite possible, considering the advanced tumor (entered the renal vein), that the tumor has come back in the lungs. Lungs as it is the most common site of metastasis for kidney cancer. A contrast enhanced CT scan of the chest or a PET/CT will determine whether this shadow is really the tumor coming back or something else. If it is indeed the tumor, then your husband will need to be placed on targeted therapy (tablet therapy for cancer)
