Type 1 is common wart, 2 plantars wart, and 6 & 11 genital warts
. Some other types and specifically 16 & 18 are related to cervical, penile, anal and oral cancers. If a person has genital warts it is more likely to cause anal than oral problems. If it is hpv 16 or 18 both ends are at risk. (condoms
will help prevent this problem.).
