Frontline medicine is all about “just do x” hacks to try to move quicker. We turn people into a fault tree, and enforce that with EMR and audit/review you create a bias to focus on the 80/20 approach. Essentially turning medicine into a helpdesk.

A family member ran into this with a brain tumor, which for a patient presenting with a headache is a 1% likelihood. Slightly elevated blood pressure was the focus in that case. Persistence and a subtle symptom changed triggered the CT scan that ultimately led to the diagnosis about 8 weeks later. Unfortunately with melanoma, 8 weeks is a long time.

Ultimately there’s no right answer. 99% of people with headaches have high blood pressure or other “normal” causes. Sending 1,000 people to CT to identify 5 tumors will cause 50 other complications.

Think of doctors like a helpdesk in a big company. Open a ticket, but work your network to get someone who isn’t dumb to think about it. If you’re too poor or don’t have friends and advocates, your outcome will be no mas.

This is something frequently missing from discussions like this.

Something that has a fairly small per-patient risk like a CT scan, causes far more pain than reduced missed diagnoses would solve if applied across the whole population.

    Not only that, but you have red herrings. Going down the rabbit hole chasing random anomalies doesn’t solve the patients problem either!

what complications are there from CT scan?

asking as someone that had it

    Not a doctor, but to my understanding there are two main issues with CT scans in this context: the radiation from the scan itself, and the fact that it can lead to "incidental findings" which then might cause a cascade of other, more invasive tests with risks of their own.

    CT scans are super valuable for all sorts of things, and the radiation dose/risk for an individual is small, but at a societal level using them freely as a "might as well" kind of test results in a lot of excess radiation exposure. This recent research suggests up to 5% of cancer diagnoses each year could be from CT scan radiation: https://www.ucsf.edu/news/2025/04/429791/popular-ct-scans-co...

    The "incidental findings" side is an interesting dilemma: CT scans often reveal other stuff beyond what they were initially ordered for, but which can't be identified solely by the CT scan itself. So, if something looks a little weird on the CT scan it creates an imperative to figure out what it is, so there are additional tests, each of which carries its own risks and also consumes limited resources that might otherwise have been used for people with more definitively concerning findings. https://en.wikipedia.org/wiki/Incidental_imaging_finding
