Embryonal Carcinoma

Embryonal carcinomas are a type of non-seminoma cancer that is present in about 40% of testicular cancer tumors, but pure embryonal carcinomas occur only 3-4% of the time. When seen under a microscope, these tumors can look like tissues of very early embryos. This type of non-seminoma tends to grow rapidly and spread outside the testicle. Embryonal carcinoma can increase blood levels of AFP and HCG.  Visit National Institute of Health for more information.
