Hi. I wouldn't be too worried about that elevation of AFP. It is a very mild elevation. In adults, some AFP is normally being produced by the liver. Sometimes when the liver sustains injury (example: viral hepatitis), more AFP is released into the bloodstream, causing its levels to rise.
From the additional information you've mentioned, I seriously doubt that you have testicular cancer. If you really want to make sure, you can have your AFP levels taken two months from now, just to see if it increased further.
CT scan came up clean -- ntg on liver or lymph nodes. my urologist wants me to see a gastro-intestinal specialist for the next step. he wanted to wait on the x-ray of the lung until after this visit.
the other marker which i couldnt recall was HCG. that came up normal (negative).
any idea why my AFP would be abnormal? what else can cause this abnormality or can this abnormality be a normal variation?
TIA
Hi. Testicular cancer comes in two forms, seminomatous and non-seminomatous. Alpha fetoprotein (AFP) is a tumor marker which is elevated for the non-seminomatous type, but is not increased in seminomatous cancer. There are two other markers: Beta-HCG (human chorionic gonadotropin) and LDH (lactate dehydrogenase) which may be elevated when either type of testicular cancer is present.
Although an AFP level of 15 is elevated (normal: less than 5 ng/ml), cancer is usually suspected only when the levels reach more than 25 ng/ml (AFP in non-seminomatous cancer is usually found in the level of hundreds of nanograms/ml). Since the levels of the other markers are normal, and no mass was found on ultrasound, I am having doubts about the diagnosis of testicular cancer in your case. Still, it might be prudent to have that CT scan and x-ray done, just to be sure.
Feel free to make a post if there are further developments, or if you have other questions.
