Penile warts are diagnosis that a trained doctor can make without a biopsy.  If patients have many warts or ones that look suspicious for other lesions like cancer I often biopsy a representative sample and freeze (with liquid nitrogen) or burn (electrocautery) or laser (C02 or YAG) the rest.  If a patient has warts on the foreskin and wants a circumcision I sent the tissue for biopsy. 

If your doctor didn’t send a biopsy and it didn’t come back that’s fine.  If it keeps coming back and there was never a biopsy ask your doctor to sent a piece to the lab or make sure they are convinced its not cancer.

I hope this post is helpful.  Go to our find a physician tab if you need an evaluation

Thanks,
