What's the harm in having an early test that is more accurate than what has been developed?
I know RECAF is not 100% at early stage detection but at least for prostate cancer it blows away PSA, and is able to detect stomach cancer at a fairly early stage too.
Even if detection is 75-85% during the first stage....it's better than not finding or not bothering to try to detect an early stage cancer.
If BOCX is the only semi-mostly-reliable test at the 1st and most critical stage for beating cancer....then why not?
