Hi, I am from Ireland.
I just want to let you know that my Dad was diagnoised with Kidney cancer in April, there was also parts on his lungs and liver. In the first hostipal he was told to go home and get all his affairs in order and that was that. then he was transfered to a hostipal 2 hours away and put under the care of a very good doc from Czech Republic, he was very positive. He was put on different drugs, and none of them seemed to work, for a while he was getting very forgetful and very weak. Doc thought that the cancer had spread to his brain and in his bones cos his calcium levels were very high. So he done a brain and bone scan. Thankfully there was nothing there. The forgetfullness was due to his high calcium levels and dehydration. So maybe this might be the same with your Mom.
He started a new drug 1 month ago called Suttent, he was the first person in Ireland to go on this drug, again doc was very positive. So far he has been taken off the drug twice cos the side effects are quite bad on him. At the moment he is at home, but getting weaker by the day, he is meant to be going for a scan in 2 weeks time to see if this drug done him any good. I don't think it will be very good though unfortunately.
I'm the baby of the family and am very close to my Dad, and to make things worse, I am expecting my first Child in December, and i don't think that he will be around to see his grandchild. He has 2 other grandkids who he whorpships.
I think all that can be said is that this disease is a pain in the A***.
