It's about control.

Also a work of fiction

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

My understanding is that if they've lasted at least a month and haven't died on you, you probably got a "good" batch and what you have now will be what it stays as for the most part, but a fair number of gulikits just sort of crap out at the 1-2 mo mark. So heads up on that.
