kidney cancer / breast cancer

i have breast cancer and my husband has kidney cancer, my husband started off being ill feb 2005 they first diagnosied kidney stones for this. the left kidney failed to function due to them finding kidney stones,as it had blocked the passage from the kidney which in turn made the kidney to not function at all. after all the tests and small operations they finally decided that the kidney had to be taken out,this was done last april 6th 2006. in which since this he was told that they found cancer in the kidney,they also stated there was a problem with the lymph nodes on the left side were his kidney was but no one has explained as to what. as of up to today he has and still is very poory, he has lost more than 3 stone in weight from when he fist became ill,cannot eat very much,also now has very high blood pressure,and got rather a lot of pain and discomfort in the lower groin area and in his back area were the kidney was.he collapses in pain a lot of the time and the only way he can ease the pain is to curl up in to a ball which seems to help a little. on the eating side they sent him to a gastrenterology in case he had a problem in his tummy which was preventing him from eating,we just would like some one to give us any idea as to why he s still in the same ammont of pain and doesnt seem to be getting better only worse.
