Extra nipples [accessory nipples] are very common. They normally occur on one side but can occur on both and occur normally in a line underneath the nipple.

They vary in size significantly and this one, I would classify as a moderate size.

They are relatively straight forward to remove as shown in the video, leaving a thin narrow scar at the side of the extra nipple.

Many people are not aware that they have an extra nipple in this region. They think it is a mole. In some cases, sometimes in men they can actually secrete milk occasionally and in women this usually occurs when they are breast feeding.
