I read the full body scans are not entirely accurate compared to specific/localized scans. But definitely helpful, for example I read x-rays don’t pick up lung cancer until much later. Whereas mri’s will pick it up? CT and the PET scans are the most accurate cuz the liquid will light up but itself has a prevalence of causing cancer, higher chance the younger the individual is. Also this xkcd is great at illustrating radiation doses https://xkcd.com/radiation/ https://xkcd.com/radiation/
