A single blood draw promises to screen for more than fifty cancers. A full-body MRI can capture you head to thigh in under an hour. But should you actually take one?

In this episode, Jeff Krasno walks through the science, the marketing, and his own experience taking the Galleri test after his father's death from cancer. He compares Galleri to direct-to-consumer MRIs from Prenuvo and Ezra, and lays out what the evidence does and doesn't support.

How Galleri and full-body MRI actually work
What the recent NHS Galleri trial showed
Lead time bias, overdiagnosis, and the diagnostic cascade
Four honest questions to ask before getting screened
Why lifestyle remains the biggest lever for cancer risk

This episode is for anyone considering direct-to-consumer cancer screening, navigating a family cancer history, or trying to read between the lines of wellness marketing.
