Description: The most important application of AFP (Alpha-Fetoprotein) testing in cancer management is for testicular cancer. Although not present in pure seminoma (testis cell tumor), elevated serum AFP is closely associated with nonseminomatous testicular cancer. AFP is not recommended as a screening procedure to detect cancer in the general population.
