These glands secrete oily fluid that lubricate and protect the nipple during breastfeeding. Signs of breast most cancers may embody a lump within the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a pink or scaly patch of pores and skin. The morphologic variations in the dimensions, form, volume, tissue density, pectoral locale, and spacing of the breasts determine their pure form, look, and position on a lady’s chest.

Milk exits the breast through the nipple, which is surrounded by a pigmented area of skin known as the areola. The area between the breast and the pectoralis main muscle, called retromammary house, gives mobility to the breast. In girls, the breasts overlie the pectoralis major muscles and prolong on average from the extent of the second rib to the extent of the sixth rib within the entrance of the rib cage; thus, the breasts cover much of the chest space and the chest partitions. The axillary lymph nodes embrace the pectoral (chest), subscapular (under the scapula), and humeral (humerus-bone area) lymph-node groups, which drain to the central axillary lymph nodes and to the apical axillary lymph nodes. The chest (thoracic cavity) progressively slopes outwards from the thoracic inlet (atop the breastbone) and above to the lowest ribs that assist the breasts. Throughout the menstrual cycle, the breasts are enlarged by premenstrual water retention and momentary development.
