Usually, they resemble small, pink or white bumps. They may look like the warts you find on your finger, or they may be much smaller. Some are so small that you can't see them individually, but see only a group of them as a cluster.
Even a good doctor may have trouble seeing genital warts because of their size. It's also hard to distinguish genital warts from normal bumps, abrasions or pinched skin. One way that physicians can check is by putting acetic acid on the area. When this happens, the warts will turn white. Doctors also use a colposcope, a lens that works like a telescope, to see the area more clearly. These are two methods used to determine if the bumps are genital warts.
