What alpha fetoprotein level would suggest hepatocellular carcinoma?

Alfa feto protein : Normally in the upper hundreds or thousands as i recall.

Depends : AFP is not particularly sensitive as it can be elevated in patients with viral hepatitis and no cancer and normal in patients with cancer. We use a cut off of approximately 200 to raise suspicion for hcc in patients with liver disease. In patients with a lesion in the liver and no underlying liver disease, any elevation in AFP above normal would likely be hcc.
