My husband has been diagnosed with a 2.4cms renal cell carcinoma. I can't understand why he is to have no treatment. The Urologist and MDT have decided to wait for 6 months and then he has to have another CT scan. Why wait 6 months? It is in the mid pole of his right kidney and they have said it is in a difficult place to biopsy so they will wait for the 6 months....... By waiting 6 months does this not mean the tumour could grow ?
