Guess what CT scans cause (in aggregate populations): Cancer! It's literally a buttload of xrays.
To put some concrete numbers on it,
"They estimated that one full-body CT scan in a 45-year-old person confers an increased lifetime risk of cancer death of 0.08%, which is approximately 1 in 1250 people. Moreover, annual scans from ages 45 to 75 years could result in an increased risk of cancer mortality of 1.9%, or approximately 1 in 50 people."

- steveBK123 3y agoYes, annual is overkill more likely than not, but there are countries that do periodic CT scans above a certain age. Knowing a number of people in their 30s-50s who passed or had close calls with slow moving but symptomless cancer caught early only because of an unrelated accident.. I'd think CT scans every 5 years or something past say 40ish probably has a good ROI for the individual. That said, it doesn't have a great ROI for insurance companies, which is why it doesn't happen. There are numerous types of internal organ cancers that are incredibly slow moving (10-20+ years) but by the time they give you symptoms you are in stage 4. And many of these have essentially no alternative screenings for early warning - thyroid / liver / pancreas / kidney / etc.
