  4. Anatomy of the Breast

  5. Appearance ∙ each breast is generally circular or tear drop in shape ∙ one breast is often larger than the other ∙ a nipple is in the center of each breast ∙ the nipple may stand out, be flat or pulled in ∙ the colored area around the nipple is called the areola ∙ the areola may be pink, brown or black like our complexion ∙ little bumps called Montgomery’s glands may be seen on the areola ∙ hair follicles are common around the nipple

  6. Position • ◦ the breast extends from the collar bone to bra line and breast bone to the armpit • ◦ breasts are positioned over the ribs and two muscles • ◦ the muscles are called the pectoralis major and pectoralis minor muscles

  7. Composition each breast has 15-20 lobes each lobe has many small lobules (like a stem of grapes) breast milk is produced in the lobules slender tubes called ducts carry the breast milk to the nipple www.cancerquest.org

  8. the nipple has 6-8 openings where the milk is secreted fatty and fibrous tissue provide shape and support to the breast www.cancerquest.org

  9. THE BREAST Vessels Chest wall muscle Lymph node Supportive ligaments Lymph channel Fatty tissue Milk lobes (glands) Lactiferous sinus Lactiferous duct Nipple Areola Illustrations: C2007 GCT II Solutions and Enterprises Ltd.

  10. BREAST DEVELOPMENT begins during the 6th week of fetal life develops in a line called the milk ridge fetal development

  11. The Milk Ridge the milk ridge runs from the armpit to the groin the line shrinks by the 9th week of fetal life remaining only in the chest area in animals the ridge remains, which is why they have multiple nipples occasionally a woman will have an extra nipple (on this line) which is often mistaken for a birthmark

  12. 80-90% of all infants (boys & girls) have nipple discharge on the 2nd or 3rd day of life breast tissue is present at birth the tissue is sensitive to the mothers hormones circulating through the placenta this discharge is called witch’s milk and goes away within a couple of weeks

  13. a bud of breast tissue begins to grow under the nipple one breast may always be larger one breast may develop more quickly than the other at puberty the ducts begin to grow and reach full growth around the time menstruation begins the female hormones estrogen and progesterone affect breast growth

  14. there is a large variation in breast size

  15. Breast Size • ◦ the proportion of milk glands, ducts and fat in the breast changes with age • ◦ during puberty the breast is mainly ducts • ◦ breasts of 20 year old women are mainly lobular (milk glands) tissue • ◦ size increases dramatically in pregnant and breastfeeding women • ◦ breasts of women over 50 years are mainly fatty tissue • ◦ because of the fatty makeup of breasts, size can change as a person’s body shape and size changes
