Everyone keeps reporting different things about his cancer diagnosis. Hodgkin's and non-Hodgkin's can be very, very different. Sounds like they caught it early either way, but between all the draft tweets and site blurbs about this kid, it's like 50% reporting Hodgkin's and 50% non-Hodgkin's. Simple thing to get wrong if all you're looking at is the word, but it's actually a big deal.
Again, sounds like he's doing well regardless, but between all the conflicting info and the likely more reliable sources being written in Cyrillic, I'm confused.
