Yes but, is it profitable?

Someone has to ask the real world questions

If everyone gets tested yearly until they die, this could total as much as most cancer treatments and suffering combined and it would probably still be better for everyone if nobody has to go through that anymore.

Good point. On the other hand, Canada didn't fare any better even without firing its pandemic response team. I suspect project warp speed would have been welcomed either way, even if it was more important in this timeline.

“Canada's per capita case rate has generally been less than half that of the US"

A million americans died of COVID (yes, some of them would have died without); but half a million would still be very bad.

Bit misleading. Tumour-associated antigens can very easily be detected very early. Problem is, these are only associated with cancer, and provide a very high rate of false positives

They're better used as a stepping stone for further testing, or just seeing how advanced a cancer is

That is to say, I'm assuming that's what this is about, as i didnt rwad the article. It's the first thing I thought of when I heard "cancer in bloodstream", as the other options tend to be a bit more bleak

Edit: they're talking about cancer "shedding genetic material", which I hate how general they're being. Probably talking about proto oncogenes from dead tumour debris, but seems different to what I was expecting
