Is embryonal carcinoma aggressive?
Embryonal carcinoma is an aggressive tumor that tends to metastasize early. Embryonal carcinoma is often associated with other cell types in the metastatic sites. Pure embryonal carcinoma represents 3–6% of GCT. Choriocarcinoma is another aggressive tumor with a high potential to metastasize (lungs).
Why is embryonal carcinoma called?
Embryonal carcinoma can increase blood levels of a tumor marker protein called alpha-fetoprotein (AFP), as well as human chorionic gonadotropin (HCG). Yolk sac carcinoma: These tumors are so named because their cells look like the yolk sac of an early human embryo.
