I got a invitation to this through the post. Had an initial phone call to assess suitability. CT scan this week. I have no problem with routine breast, cervical or bowel screening tests - glad to have them. But as a former smoker it's the one thing I fear, because I know smoking was a stupid thing to do and I'm ashamed of myself. I was a secret smoker, it was how I coped with stress. Nobody knew I smoked as I never smoked in public, in front of anyone. I'm stressed now waiting for the test and I know I'll be stressed waiting for the results. But have no desire to light up. Has anyone had the test and would like to share the outcome.
