I have been on nexavar for 7 months now.I was diagnosed with kidney cancer 5 years ago.For the first two years I was taking interferon-alpha to prevent its return to another area.This worked very well for me.After about 3 years or so it returned to my lung.I was given 30 radiation treatments and shortly therafter put on nexavar.The cost for the nexavar is over 6,000.00 per month,thank God I have insurance the co-pay is only 25.00.Ask your doctor about interferon-alpha made by Schering corp.,it kept me well for over 2 years and did not cost that much.I wish you well,God bless .
