Note that the axillary tail has not been labelled in this diagram. The lymphatic drainage of the breast is of great clinical importance due to its role in the metastasis of breast cancer cells. They are distributed throughout the body of the breast. Younger women with an age of less than 40 years or women over 80 years tend to have a poorer prognosis than post-menopausal women due to several factors. Mammographic screening , where X-ray images of the breast are taken, is the most commonly available way of finding a change in your breast tissue lesion at an early stage. Poverty is a major driver for disparities related to breast cancer. Nerve Supply The breast is innervated by the anterior and lateral cutaneous branches of the 4th to 6th intercostal nerves. Refer a Patient. In rare cases, men can also be diagnosed with breast cancer. The expression and activation of ER due to lack of estrogen can be stimulated by extracellular signals. Most people with breast cancer have no symptoms at the time of diagnosis; their tumor is detected by a breast cancer screening test. The second most common cause of death from cancer in women was lung cancer, the most common cancer worldwide for men and women. The base of the breast lies on the pectoral fascia — a flat sheet of connective tissue associated with the pectoralis major muscle. It has been suggested by zoologists Avishag and Amotz Zahavi that the size of the human breasts can be explained by the handicap theory of sexual dimorphism. In contrast, abortion is associated with increased risk of carcinomas of the breast.

The breasts are paired structures located on the anterior thoracic wall, in the pectoral region. They are present in both males and females, yet are more prominent in females following puberty. In females, the breasts contain the mammary glands — an accessory gland of the female reproductive system. The mammary glands are the key structures involved in lactation. In this article, we shall look at the anatomy of the breasts — their structure, innervation, vascular supply and any clinical relevance. The breast is located on the anterior thoracic wall. It extends horizontally from the lateral border of the sternum to the mid-axillary line. Vertically, it spans between the 2nd and 6th costal cartilages. It lies superficially to the pectoralis major and serratus anterior muscles. At the centre of the breast is the nipple , composed mostly of smooth muscle fibres. Surrounding the nipple is a pigmented area of skin termed the areolae. There are numerous sebaceous glands within the areolae — these enlarge during pregnancy, secreting an oily substance that acts as a protective lubricant for the nipple.
