Part of the reason I consider those arguments weak, is we could be dedicating research money to solving those problems, but we don’t. In his video, he also is very quickly glossing over the counter points. For example, the patient who received a heart stent because they detected early narrowing of an artery would not be given a stent today, and instead it would be monitored, which is a good thing. For the breast cancer bit, two paragraphs show up on the screen showing a study that followed women with DCIS. 5/28 of those women died of breast cancer. So by the numbers in that study, testing positive means you would have an 18% chance of dying from breast cancer if you did nothing. Idk about you, but if my ods were practically 1 in 5 I’d be monitoring the situation. Again in the anecdote the patient chose to operate too early, and a good doctor would be advising against that. Lead time bias is the only argument I think isn’t weak, but there also isn’t really enough data on it for us to know for sure. That and the fact that deaths to cancer remains steady instead of going down as diagnosis goes up. I still think it would be better to screen people and monitor them if they test positive rather than wait for symptoms, because so often the symptoms come far too late. I also think more research could be done to reduce false positives and understand what makes some cancer not deadly. It’s severely under funded research because it doesn’t make money and it isn’t glamorous, but it could absolutely save lives
