Do i need to worry about a brain tumor caused by a 2 brain ct scan radiation i got 3 years ago if i have some dizziness now im 27 years old help me ?

Get checked,,,: You should get your dizziness checked out but at your age it's highly unlikely to be a brain tumor even with your history of ct scans. It's likely due to another possible cause, like lack of hydration, or sleep or too much lethargy/drowsy inducing medication. Still get checked if you're worried, but keep in mind one of these more likely explanations. Good luck.
