So my anxiety is not as bad as it used to be but it still bothers me at times. I'm thinking back about a lot of things I've had checked and have had lots if tests done. I've had two concussions in a year and had three ct scans from that. Also had two or three ct scans of my stomach and chest area. Have had some x rays of my stomach and three are some more times in the past year. Also I've had more ct scans and X-rays over the previous years and I can't shake the cancer worries. My dad's dad died from cancer and my dad has cancer so now I feel like I have a predisposition to it and all those tests haven't helped.
