AFP level raises suspicion for HCC in at-risk patients when above what threshold?

Alpha-fetoprotein helps flag potential hepatocellular carcinoma in people with cirrhosis or chronic liver disease. Lower levels like 20 ng/mL catch many cancers but many benign conditions also raise AFP, so that threshold isn’t specific enough. A higher cut-off, around 200 ng/mL, provides better specificity: when AFP exceeds 200 ng/mL in an at-risk patient, the likelihood of HCC is high enough to justify prompt imaging with contrast-enhanced CT or MRI to look for a tumor. Very high levels (thousands) are more specific but less useful for initial screening because not all HCCs raise AFP that high, and some non-cancer conditions rarely cause such elevations. Remember, AFP alone doesn’t diagnose HCC—imaging is required to confirm.
