Stages of Breast Development (Tanner Stages)First 3 stages
Thelarche stages:Breast developmentTanner I: PrepubertalElevation of only papillaTanner II: Breast bud stageElevation of breast and papilla as a small moundEnlargement of diameter of areolaTanner III:Further enlargement of breast and areola with no separationof contours
Last Stages & Onset
Tanner IV:Areola projected above levelof breast as a secondary moundTanner V: Mature stageRecession of areola mound to the general contour of thebreastProjection of papilla onlyOnset of breast development occurs approximately:1 year prior to onset of pubichair development2 years prior to menarcheComplete process usually occurs over a 4 year period

Breast Cancer Risk factors and their relative risk
Groups:ModifiableNon-modifiableUncertain,Controversial or Unproven
Non-modifiable (factors you can not change)
Gender100 times more common in women than menAgeMOST IMPORTANT2 of 3 invasive breast cancers women 55 or olderGenetic5-10% thought hereditaryBRCA1 & BRCA2 most common causeRisk as high as 80%, tend to occur in younger women andaffect both breastFamily HistoryFirst degree doubles risk, two first degree increase risk fivefoldPersonal HistoryIncrease risk a new cancer in other or same breastRaceWhite more likely to developAfrican-American more likely to dieDense breast tissueHigher riskPrevious chest radiationVaries with age, chemotherapy.DES (Diethylstilbestrol) Exposure:May increase the risk of breast cancer in the users of DES and in their daughters.Used 1940’s-70’s decrease miscarriageMenstrual periods:Menarche prior to age 12Menopause after age 55Certain benign breast conditionsLobular carcinoma in situ
Modifiable: (Life style related, changeable)
Postmenopausal ObesityExercise§Lack of physical activityAlcohol§ Increases with 2 to 5 drinks a dayHormone replacement§Combined HRT increases risk, return normal 5 years after stop§ET alone does not seem to affect risk, increase if used more 10 yearsRecent oral contraceptive use§Slightly higher than those that never used§Return to normal after stoppingChildbirth§Breast feeding§Nulliparity or late age at birth of first child

SIGNS & symptoms of breast masses
Fibrocystic Changes20-50 yearsUsually bilateralMultiple or singleRoundSoft to firm; usually elasticMobileNo retractionOften tenderWell defined bordersVariation with Menses,Except with estrogen therapyFibroadenoma15-25 years, up 55Usually bilateralSingle; may be multipleRound, disc like, or lobularUsually firm, rubbery Very mobileNo retractionUsually nontenderWell defined bordersNo variation with mensesCancer30-90 years, most common over 50Usually unilateralSingle, may coexistIrregular or stellateFirm, hard, stonelikeFixedUsually have retractionUsually nontenderPoorly defined borders, irregularNo variation with menses
Visible signs of breast cancer
Table 10-2 Retraction signs As breast cancer advances, it causes fibrosis (scar tissue). Shortening of this tissue produces dimpling, changes in contour, and retraction or deviation of the nipple. Other causes of retraction include fat necrosis and mammary duct ectasia. Abnormal contours:
- look for any variation in the normal convexity of each breast, and compare one side with the other. Special positioning may again be useful. Flattening of the quadrants. Skin dimpling
- look for this sign w/the patient’s arm at rest, during special positioning, and on meoving or compressing the breast. Nipple Retraction and Deviation:
- A retracted nipple is flattened or pulled inward. It may also be broadened, and feels thickened. When involement is radially asymmetric, the nipple may deviate or point in a different direction from its normal counterpart, typically toward the underlying cancer. Edema of the skin:
- edema of the skin is produced by lymphatic blockade. It appears as thickened skin w/enlarged pores–the so called peau d’orange (orange peel) sign. It is often seen first in the lower portion of thebreast or areola. Paget’s Disease of the Nipple
- This uncommon form of breast cancer usually starts as a scaly, eczemalike lesion that ay wep, crust, or erode. A breast mass may be present. Suspect Paget’s disease in any persisting dermatitis of the nipple and areola. Can present w/invasive breast cancer or ductal carcinoma in situ. Nipple & Areola Montgomery tubercles
- A normal finding. Elevated areolar glands usually associated with pregnancy
- Normal Crusting and flaking
- considerPaget’s Disease Eversion verses Inversion: unilateral or bilateral Retraction or deviation: consider cancer Retraction & Dimpling Ask if new onset…recent unilateral inversion of a previously everted nipple suggests malignancy Peau d’orange Edema of the skin which is associated with cancer, often appearing first around the nipple
Normal changes of the breast
Menstruation: Enlargement can occur 3-5 days prior to menstruationDO NOT examine breasts at this time
- due to an increase in nodularity from fluid build-up
- increased pain and tenderness¡Best time to evaluate breasts is 5-7 days after onset of mensesPregnancy: Fuller and more firm
- breasts can change two cup sizes during pregnancy & lactation Nipple changes
- areola darken
- nipples enlarge & become erect Third trimester
- colostrum: thin yellowish secretion FYI: After the baby is born, secretion of colostrum will stop and milk production begins if the mother begins nursing within 24 hours
Palpable masses of the breastAge 15-25
Table Page 410Age: 15-25Common Lesion: FibroadenomaCharacteristics: Usually smooth, rubbery, round, mobile, often tender
Palpable masses of the breast–Age 25-50
Table Page 410Age: 25-50Common Lesion: CystsCharacteristics: Usually soft to firm, round, mobile; often tenderCommon Lesion: Fibrocystic changesCharacteristics: Nodular, ropelikeCommon Lesion: CancerCharacteristics: Irregular, firm, may be mobile or fixed to surrounding tissue
Palpable masses of the breast–Age Over 50
Table Page 410Age: Over50Common Lesion: Cancer until proven otherwiseCharacteristics: Irregular, firm, may be mobile or fixed to surrounding tissue
Palpable masses of the breast–Pregnancy/lactation
Common Lesion: Lactating adenomas, cysts, mastitis, and cancer
