What did ronaldo have an operation on when he was 15?
When he was 15, Ronaldo was diagnosed with a racing heart, a
condition that might have forced him to give up playing football.
The Sporting staff were made aware of the condition and Ronaldo's
mother gave her authorisation for him to go into hospital. While
there, he had an operation in which a laser was used to cauterise
the area of his heart that was causing the problem. The surgery
took place in the morning and Ronaldo was discharged from hospital
by the end of the afternoon; he resumed training only a few days
later
