Toshiba device tests cancer types from a drop of blood

Quite rare to jump straight to an MRI - a chest MRI is a half hour deal. More common to do a CT Chest which has a 1:500 risk of causing cancer

Does this mean that out of the 5000 false positives, 10 people will actually GET cancer by doing a follow-up CT exam?

We don't really know. Data that show X dose of radiation increases the probability of developing cancer by Y% is based on studies on survivors of atomic blasts. The number of people exposed to an amount of radiation equivalent to a handful of CT scans is pretty small relative to the effect size that's claimed, so there is reason to be skeptical.

See https://www.scientificamerican.com/article/how-much-ct-scans... for a jumping off point into this type of research.

"1:500 risk" - citation?

Looks like I may have been misrepresenting the risk to some patients; also looks like i've probably caused around 4 cases of cancer
