I think he was cured 3 years ago or so. I think he was around 5 when they diagnosed him with it. He is 10 now, if I'm not mistaken.
He was lucky they found out what he had very early, so it was relativately easy to cure. He had to use tons of medicines daily though, which had various side-effects from being hungry all day long to losing hair. I'm not to sure about how much chemo he had and all.
He is fine nowadays, and as lively as before.
Much strength to you and your cousin Yoda...
