I bet Czech radios are just as weird. .]
Anyways, I am really sorry to hear what happens to your brother, but I firmly believe he would be strong and you all too and get healen... Also, I think if it were a cancer in the very first stadiums, there would be a help for that, people I've known with stadium of said illness like that usually had to undergo a chemotherapy [is that a word?] which wasn't exactly pleasant, but cancer gave up and went away...
Though, I am not sure what the therapy situation is like in [Russia you wrote, but not sure about the region ]. Still, good luck to you and your brother!
