How startled would you be if you suddenly found a yellow stain on your underwear or noticed something coming from your nipple while showering? Your heart might sink as worries cross your mind, wondering if it might be a serious illness. However, there is no need to be overly anxious; most nipple discharge reflects either a natural bodily change or a harmless sign.
