What are genital warts? Genital warts may be small, flat, flesh-
colored bumps or tiny, cauliflower-like bumps. Genital warts are
caused by the human papillomavirus (HPV). There are many kinds
of HPV. Not all of them cause genital warts. HPV is associated
with cancer of the vulva, anus and penis. However, it's
important to note that HPV infection doesn't always lead to
cancer. Written by familydoctor.org editorial staff
