I am guessing, since the article you link doesn't actually link to the scientific study, that it is referring to: http://pediatricbioscience.com/publications/pdf/Pub16.pdf This did not examine any form of causality, as the currently-linked study did, nor did it evaluate the children themselves. By not controlling for evaluation mechanisms, the study you link only addresses patterns of early diagnosis and treatment. While it is interesting, the researchers themselves say that the data is hardly conclusive. The current study, on the other hand, explores not just correlation but causation, and thus is far more persuasive.
Second, you are comparing increase in risk to total overall risk. The percentage increase for men going from age 25 to 40 is 110%, not 2%. The study you link found a comparable number for women over age 40 of 0.4%.
