My mother was diagnoise with clear cell renal cancer 12 months ago, they were unable to remove the kidney so did an embolisation, the cancer does appear to be slow growing as in she still feels fine although there is evidence of the cancer in lymph nodes near kidney, stomach and chest. She has had no other treatment however votrient has been suggested and it has been suggested to wait until her quality of life is not so good and then take rather than take now while she feels good as side effects are potent. Any thoughts appreciated??
