question: Hello doctor,I had some lab work done and this was part of the blood test AFP, serum tumor marker 1.9, 0.0-8.3 (ng/mL). Can you please explain this to me? Five years back, I had a complete laryngectomy and a flap. So, I breathe through a stoma but my doctor did all the tests and found polyps and liver cyst and I was diagnosed with cirrhosis.
