elapid said:As I am a surgical oncologist I can tell you that your friend is wrong. HCG is used as a marker for the diagnosis of testicular cancer and determining a prognosis. The HCG level correlates with the volume of disease (ie, higher levels, the worse the disease), but still increases above normal reference ranges even when the tumor is not palpable or even bothersome. Apart from diagnosis and determining prognosis, HCG levels are also importantly used for post-treatment screening: If HCG levels do not decrease to normal levels or later increase, then this indicates that there is evidence of metastatic spread. This can occur despite there being no physical (or imaging) evidence of measurable disease. So this blows your friend's theory.
From the Testicular Cancer Resource Center: "Blood tests: Some testicular cancers secrete something called tumor markers, high levels of certain proteins that can be detected through blood tests. These markers of testicular cancer include alpha-fetoprotein (AFP), beta human chorionic gonadotropin (ß-HCG) and lactate dehydrogenase (LDH). If a guy's AFP or HCG level are above normal AND there is something wrong with his testicle, then you can assume that he has testicular cancer. If the tumor markers do not fall back to normal after an orchiectomy, then you can usually assume that the cancer has spread, even if no other tests show where it has gone."
Oldnell, you didn't see the above response coming. You just got owned.
Brilliant!!!
