You're absolutely right. The earlier the detection, the better. Everybody knows that's the case. For some cancers that's fairly straightforward to do, but for many, as you say, they are silent. We don't know the answer.
What's happening is that people are starting to use—back to your original point about artificial intelligence—that kind of computing power to analyze samples from patients in a much more sophisticated way. For instance, we look for what's called circulating tumour DNA, which may be in your blood and be a very early marker of cancer. That sort of stuff is starting to happen now, applying artificial intelligence to deconvolute some of these things and make them possible.
