The part I find most interesting is how they found the markers: they used artificial intelligence to find them.
They did several different genetic testing courses for my wife. Every time they did one she had to sign off that it could be used in research.
One test was about a year after treatment to compare her blood to “her” tumor to see if there was anything hiding in her system. It was very “Star Trek” in its use of genetics and scanning.
One of the things the oncologist told us is that when we were reading stuff on the internet is to not read any articles older than 2 years because the changes in treatments and diagnostics were changing that fast.
From an external point of view it’s fascinating. While you are in the middle of it it’s scary as hell.
