cancer screening has quietly evolved, but in many centres, the tools we use have not.
For years, guaiac based FOBT served as a starting point, but it detects peroxidase activity rather than human blood, which means results can be influenced by diet, specificity remains limited, and early or proximal lesions may go undetected.
The shift to f***l immunochemical testing (FIT) was an important step forward because it brought biological specificity into screening by detecting human hemoglobin, but even here, we are still relying on a single biomarker in a system that is far more complex.
represents the next logical step.
By detecting both hemoglobin and the / complex, it captures signals that persist during bowel transit and improves the likelihood of identifying lesions that would otherwise be missed, particularly on the right side of the colon where detection has traditionally been a challenge.
In a country like India, where screening uptake is still low, diagnoses often occur late, and endoscopy resources are finite, the need is not just for better tests, but for smarter screening strategies that can be scaled, triaged, and integrated into routine clinical practice.
This is where the real impact lies.
Moving from chemical detection to biological interpretation, and now to dual biomarker coverage, is not just a technological upgrade, it is a shift in how we approach early detection itself.
Perhaps it is time we re-evaluate not just how we screen, but what we choose to screen with.
