The human papillomavirus (HPV) is a sexually transmitted disease that may cause small, painless flesh-colored bumps around the genitals, anus and/or mouth. The virus cannot be cured. Some strains of HPV can cause cervical cancer in women, which is why it is very important for them to get regular Pap tests. Early detection can prevent cervical cancer. HPV has also been linked to penile and anal cancer in men in some rare cases.
