What are the risks of CT scans?

The risks of CT scans primarily relate to radiation exposure. Andrew Huberman discusses that common sources of radiation for most people include medical procedures like CT and PET scans. Such procedures are not harmful when used in moderation; however, frequent exposure to the high levels of radiation from CT scans can increase the risk of cancer 1.

Peter Attia outlines the irony of using full body CT scans to screen for cancer since a whole-body CT scan involves around 30 to 50 milliseverts of radiation, which is a significant dose 2. He emphasizes that the goal is to avoid unnecessarily high levels of radiation exposure while also making use of these powerful diagnostic tools when appropriate.

It's important to balance the risks and benefits when considering CT scans and to consult with a healthcare professional to make informed decisions about their use.
