[Marvel] Why didn't Matt Murdock tell everyone about his powers when they first developed as a child?

Young Matt Murdock is exposed to radio active waste which gives him radar powers.  Why didn't he immediately tell everyone about this?  Its a miracle of medical science.  It should have been in the news.  

Did he know he was going to need a secret identity, even as a child?  Did he really not tell his close friends and family?  What kind of person would do that?

He did.  The Nuns didn't know what he was talking about or how to help him, so they called in Stick.  By the time his training with Stick was done, he had an appreciation for how special his powers were, and how important it was to keep them secret.
