Are There Any Limitations to Using hCG as a Tumor Marker?
While hCG is a useful marker, it is not without limitations. High levels of hCG are not exclusive to cancer; they can also be seen in pregnancy and other non-malignant conditions. Therefore, elevated hCG levels must be interpreted in conjunction with clinical findings and other diagnostic tests. Additionally, not all cancers produce hCG, and its absence does not rule out malignancy.
