It seems like it's not widely studied and it's a toss up in the medical community if they're a pre-cancer. I heard of people using liquid nitrogen.

They look like little round freckles in appearance on the base of my penis and shaving causes them to multiply. I'm almost positive they're bp because they look nothing like genital warts. I had them for 7 years
