Yup, I understand. Once we've had a diagnosis of a potentially serious medical issue it's hard to put it out of mind. After I was diagnosed with thyroid cancer last year I've fretted over every minor sensation that seems a bit unusual -- difficulty swallowing, a sore throat, etc. Surgery seems to have gotten it for now without chemo. But it's always on my mind.
Before last year I wouldn't have given cancer a second thought. There's little history in my family, although my dad died of prostate cancer. Most of my family medical issues were diabetes from obesity and diet, and respiratory problems from smoking. I exercise, watch my diet, dropped 50 lbs gradually over about 15 years so it's sustainable, quit smoking more than 20 years ago, and overall my BP, HR, blood work and most diagnostics look good.
But some issues, like cancer and strokes, don't cooperate with some efforts at a healthy lifestyle. So I try to just focus on enjoying today.
