It's very difficult to talk about individual cases, and in general it's very hard to say. I just hope that he has very good treatment. It's extremely rare in someone so young. Most cancers in that age group are skin cancer, melanoma and testicular cancer, so I think that it would be very difficult to pin it down on any particular thing.
