<unk> s are benign breast tumours characterized by an admixture of stromal and epithelial tissue. Breasts are made of lobules (milk producing glands) and ducts (tubes that carry the milk to the nipple). These are surrounded by glandular, fibrous and<unk> tty tissues.<unk> s develop from the lobules. The glandular tissue and ducts grow over the lobule to form a solid lump. Since both<unk> s, and breast lumps as a sign of breast cancer can appear similar, it is recommended to perform ultrasound analyses and possibly tissue sampling with subsequent histopathologic analysis in order to make a proper diagnosis. Unlike typical lumps from breast cancer,<unk> s are easy to move, with clearly defined edges.<unk> s are sometimes called breast mice or a breast mouse owing to their high mobility in the breast.
