I have a brain aneurysm, 2.9 mm in diameter, i'm 24 now (the results are old 3 years). is it dangerous, should i do an occasional mri now and then?

Need more than that: Cerebral aneurysm is a serious life threatening condition , if event happens (if it reputes) less than 50% will survive, out of them again less than 50% walk away with out neurological damage, results with intervention(surgery or coil ) is excellent , please choose experienced team and follow their advise and save your life.

Update: If no symptoms that is good! but new study regarding size, location can guide intervention.
