Mammary gland-type accessory breasts contain real breast tissue (end of the real breast) with only approximately 30% fat; thus, they are harder and sometimes even tender to touch. They sometimes swell with the menstrual cycle and are commonly observed with an accessory nipple (third nipple). If a patient is diagnosed with mammary gland-type accessory breasts, then surgery to remove the mammary gland tissue is necessary. An incision is made similar to that in augmentation surgeries at the crease of the axillary skin with an average length of 3–4 cm. Along with removing the major mammary gland, the surgery also removes excess skin to prevent loose or sagging skin. The excised breast tissue can be sent for pathological inspection to ensure that there is no possibility of any malignant change in place.
