Located anterior to pectoralis major & serratus anterior muscles between 2nd & 6th ribs
surface anatomy
breast
Tail of Spence
Nipple
Areola
Montgomery’s glands
4 quadrants
breast
upper outer quadrant, lower outer, lower inner quadrant, upper inner quadrant
* Upper outer quadrant: location for most breast tumors
glandular tissue
breast- internal anatomy
- Lobes
- Lobules
- Alveoli
- Lactifereous duct
breast tissues
glandular
fibrous
adipose
fibrous tissue
breast
- Suspensory ligaments
- -Cooper’s ligaments
Lymphatics (Anterior Lymphatic Drainage)
breast
- > 75% of lymph drains into the ipsilateral axillary nodes.
- Drainage flows from central axillary nodes up to the infraclavicular and supraclavicular nodes.
- Small amount of lymph drains directly up to infraclavicular group, deep into chest, or into abdomen, or crosses over to the opposite breast.
Central axillary nodes
breast
: high up in middle of axilla, receives lymph from the other 3 groups
Pectoral nodes
breast
(anterior): just inside anterior axillary fold
subscapular nodes
breast
(posterior): deep in the posterior axillary fold
lateral nodes
breast
along the humerus inside the upper arm
Milk lines or ventral epidermal ridges:
breast
present during embryonic life; curve down from axilla to groin bilaterally
* Breast develop along thoracic milk line ridge
supernumerary nipple
breast- developmental considerations
an extra nipple which develops along the mammary ridge
breasts at birth
contain just lactiferous ducts; areola is not present
asolescent females
effects of estrogen on the breasts results in:
- Increased fat disposition
- - Development of duct system
- - Earlier onset of puberty
- * African Americans: mean age is 8 & 9
- * Whites: mean age is 10
- - Asymmetry (one breast may develop quicker)
- - Breast tenderness is common
Tanner’s Sexual Maturity Rating (1969) or Sexual Maturity Rating
- Five stages (full development from stage 2-5 takes an average of 3 yrs; can range from 1.5 – 6 yrs)
- Development of pubic hair
- Axillary hair (onset 2yrs after pubic hair)
monthly changes of breast
- Midcycle to onset of menstruation: increased nodularity
- 3 to 4 days before menstruation: fullness with heaviness & tenderness
- Days 4 to 7 of menses: smallest size
pregnancy
breast
-Noted changes at second month
- Increased ductal system & supporting adipose tissue
- - True secretory alveoli develop
- - Nipples become larger, darker, more erectile
- - Enlarged, darker areolae
colostrum
breast
may be expressed after the 4th month; precursor to milk (contains some amount of protein & lactose as milk but almost no fat)
milk production
breast
(lactation) occurs at 1-3 days postpartum
post menopause: decreased estrogen & progesteroneresulting in:- Decreased glandular tissue with formation offibrous tissue- Atrophy of adipose tissue- Major decrease in breast size in the 80’s;decreased elasticity sagging, flabby,flattened breasts- Axillary hair decreases
aged female- breast
- Decreased glandular tissue with formation of fibrous tissue
- Atrophy of adipose tissue
- Major decrease in breast size in the 80’s; decreased elasticity
- sagging, flabby, flattened breasts
- Axillary hair decreases
Male breast:
Male breast:
- Underdeveloped tissue behind the nipple
- Well developed areola but nipple is small
Gynecomastia:
enlargement of the male breast, temporary enlargment is common during adolescence; can occur in the aging male (from decreased testosterone levels)
Breast development
African American: mean age of 8.87
Whites: mean age 9.96
Menses:
African Americans: average age 12.16
Whites: average age12.88
Breast cancer
- Increased incidence in whites
- Lower risk in Asian, Hispanic & Native Americans, but poorer outcomes
- Alcohol use can increase likelihood of developing breast cancer
- Effect of fat in diet is questionable
