It does t take a lot of blood to check for various cancer factors. Putting a bunch of them together always made sense to me as a screening.
I think the problem as been that these tests—taken out of context with patients who don’t understand them—would clog up a system that is already stressed.
If you got a test back that showed baseline factor metrics for four cancers—you would probably freak out. Yet, everyone has some “crap” going on in the background.
This is a little late. But LDH is another important tumor marker blood test that can be helpful.
