Anyone have a CT scan?

Last month I had a chest X-Ray and this month I had a chest CT scan with contrast. This was all to rule out any postpartum heart complications bc I have been experiencing some symptoms. Everything came back normal. Today I was at the doctor and she said something like “we wouldn’t want to expose you to anymore radiation” and it sent me into a spiral. I never thought about the risk befor getting it and now I can’t stop thinking about the risk of cancer from having these scans done- especially bc I had one with contrast. If they would have found something concerning and it saved my life obviously I’d be happy we did it. But since everything was fine I’m like damn. I was just fine but NOW I’ve increased my risk for cancer... great.

Can someone who’s had CT scans please tell me that you aren’t worried about it? Or anyone who works in the field say something reassuring maybe? I have health anxiety and I tend to hyperfocus and worry about things that most people don’t lose any sleep over /:
