Aren't we all having some cancers cells in our blood and lymphatic fluids, and tissues, but those with a healthy immune response have nothing to worry about? In most cases, doesn't cancer take years to fully developed helped by epigenetic factors, but predominantly by the external ones? Won't such device when massively used for blood testing lead to predominantly false positives, redundant biopsies, and overtreatment? I think this is a great device with an enormous potential if used on narrow targets and responsibly, in general. I just think focus should be on true prevention, i.e. dietary and lifestyle changes, and not developing a false sense of assurance by living unhealthily and relying on a test to catch the results of the poor habits, and also rely on medicine being advanced enough to correct our mistakes. Of course, some factors are unavoidable today, but we also have a growing arsenal of knowledge and means to counter many of them.

in general your post says that cancer is karma payback, a disease of "dirty hands". Typical attitude of a "holier than thou" type until your get it yourself.

> those with a healthy immune response have nothing to worry about?

wrong. Cancer cells are your own cells and in general immune system have no reason to target them.

No, "karma" and "payback" do not belong to my vocabulary. Also, read more - the immune system is totally capable of attacking some cancer cells [1]. Immunotherapy is what I think will cure cancer paired with better early detection and prevention with lifestyle and nutrition changes.
