Obviously, a false diagnosis of cancer would be a disaster.
I’m not talking about all tests for cancer. I’ve only looked into two. This is what I’ve discovered.
There is a blood test, which looks for a bio-marker labeled CA125. There are doctors who will tell you that a highly positive result indicates a high probability of cancer.
Imagine being a patient on the receiving end of that news.
But wait. If you go to other sources—and no, I’m not talking about alternative practitioners, I’m talking about the mainstream—you’ll get a distinctly different view.
How about a quite prestigious organization—the Mayo Clinic?
“A CA 125 test measures the amount of the protein CA 125 (cancer antigen 125) in your blood.”
“A CA 125 test may be used to monitor certain cancers during and after treatment. In some cases, a CA 125 test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease.”
“A CA 125 test isn’t accurate enough to use for ovarian cancer screening in general because many noncancerous conditions can increase the CA 125 level.”
