I recently came across this website when searching for information for my father. My father has renal cancer and had his kidney removed back in 1998....since then his tumors came back in his kidney cavity and have been very small. he has been treated with research drugs, but at this point another surgery is an option because he has 3 small tumors one of which is on the liver. Does anyone know of a similar situation? He will be going for some consultations with Liver specialists to see if they can get it all out....at this point its scary...any advice would be appretiated.
