The rise in the preventative screening centers (such as prenuvo) that offer whole body MRIs will be interesting.
The research seems split on if it is worth it or just causes unneeded worry. Obviously if you catch something early then that is great, but there are a lot of people who have a ton of followup testing only to find out there is no issue.
There are also limitations with the level of detail a full body MRI can capture.
I could see it becoming similar to a colonoscopy where you get it like when you turn 30 or something and then every 5-10 years after that.
As part of my post-cancer screening, I have received a full-body MRI every year since 2017. In 2024, it discovered pancreatic cancer. Grateful for those years where it found nothing, but even MORE grateful when it did catch something!
