PID is also the single most common cause of tubal pregnancy, in which a fertilized egg begins to grow while still in the fallopian tube, instead of the uterus. If the tube bursts, the woman could die. They usually occur near the tip of the penis in men. In women, the warts appear on the vulva, in the vagina, on the cervix of the uterus, or near the anus. Genital warts are flat, hard, and painless when they first appear.
Genital warts tend to get bigger during pregnancy.
In rare instances, very large warts may interfere with childbirth, making a Caesarean section necessary. Like skin, the surface of the cervix is constantly being replaced with new cells from below. Generated by division of the basal cells, these new cells rise as older ones are shed from the surface. These cells are not cancerous, but signal the danger of cancer to come. As the condition progresses, truly malignant cells develop and migrate downward into underlying tissues.
