What should you do if the woman reports spontaneous nipple discharge?

Press to areola inward with your index finger - repeat from a few directions. Note color and consistency if present

Racial differences in mortality may relate to what?

Racial difference in mortality may relate to insufficient use of early detection procedures, including mammograms and breast self-examinations

Midcycle up to menstruation

Subjective data - breast

Pain Lump Discharge Rash Swelling Trauma History of breast disease Surgery Self-care behaviors Perform breast self-examination Last mammogram

In terms of environmental factors, what may contribute to early onset of puberty?

- Obesity (higher BMI) - higher incidence of early breast budding and early menarch THUS, ongoing epidemic or childhood obesity in the US is a major determinant of early-age pubertal milestones

What can cause breast cancer?

- Poor diet - Alcohol - Overweight/weight gain

4 directions to move in axilla

3 ways to palpate the breasts

1. Vertical strip pattern 2. Spokes on a wheel pattern 3. Concentric circles pattern

Skin

- Normally is smooth and of even color - Note any localized areas of redness, bulging, or dimpling; also any skin lesions or focal vascular pattern - Fine blue vascular network visible during pregnancy; pale linear striae, or stretch marks, follow pregnancy - Normally no edema is present

Menarch occurs in breast development stages ___?

3 or 4, usually just after the peak of the adolescent growth spurt around age 12.

The nurse is teaching a woman how to perform breast self-examination (BSE). Which statement by the patient would indicate a need for further teaching? "The best time to check my breasts is a week before my cycle." "I will check my breasts in the shower one week after my cycle." "I will exam my breast in a clock-like sequence so that I don't miss any surface area." "I will be sure to check my arm pits."

"The best time to check my breasts is a week before my cycle."

A pregnant woman who has breast implants asks the nurse if she can still breastfeed. What is the nurse's best response? "You should not have any problems breast feeding because your implants do not affect milk production." "When the breast implants are inserted they usually affect the milk glands, and breastfeeding is not possible." "This would depend on which type of implants were placed and which procedure was used by the surgeon. Check with your surgeon to see if your milk production will be affected."

"This would depend on which type of implants were placed and which procedure was used by the surgeon. Check with your surgeon to see if your milk production will be affected."

What might be palpable now?

- A breast lump may have been present for years but is suddenly palpable - Around nipple the lactiferous ducts are more palpable and feel firm and stringy because of fibrosis and calcification

After palpating over the 4 breast quadrants, what do you palpate?

- After palpating over four breast quadrants, palpate nipple; note any induration or subareolar mass - With your thumb and forefinger, gently depress nipple tissue into well behind areola; tissue should move inward easily

Supernumerary nipple is normal variation

- An extra nipple along embryonic "milk line" on thorax or abdomen is congenital finding - Usually, below breast near midline and has no associated glandular tissue; looks like a mole, although a close look reveals a tiny nipple and areola

Fixation

- Asymmetry, distortion, or decreased mobility with the elevated arm maneuver. - As cancer becomes invasive, the fibrosis fixes the breast to the underlying pectoral muscles.

Gynecomastia

- Benign enlargement of male breast that occurs when peripheral tissues convert androgen hormones to estrogens. - Mobile disc of tissue - occurs with obesity, cushing syndrome, liver cirrhosis, adrenal disease, hyperthyroidism, drugs, ACE inhibitors, estrogen, digoxin, psyoactive drugs

Fibroadenoma

- Benign tumors, most commonly present as self-detected in late adolescence - Solitary nontender mass that is solid, firm, rubbery and elastic. - Round, oval or lobulated. - 1- 5 cm - Freely movable, slippery, fingers slide easily through tissue. - Diagnose by triple test (palpation, ultrasound, needle biopsy).

Adolescent girl - when does breast development occur?

- Breast development usually begins on an average between 8 and 10 years - Expect some asymmetry during growth; record stage of development using Tanner's staging

What are complementary screening measures?

- Breast self examination (BSE) - Clinical breast examination (CBE) - Mammogram

What breast changes occur at puberty?

- Breasts enlarge, mostly as a result of extensive fat de-position; duct system also grows and branches, and masses of small, solid cells develop at duct endings; these are potential alveoli - Puberty is occurring earlier - Tenderness - Onset of breast development occurred at an average (mean) age between 8 and 9 years for black girls and by 10 years for white girls; earlier studies cited breast development beginning at an average age of 10 to 11

The pregnant woman

- Breasts increase in size, as do nipples - Delicate blue vascular pattern is visible over the breasts - Jagged linear stretch marks, or striae, may develop if breasts have large increase - Nipples become darker and more erectile - Areolae widen; grow darker; and contain small, scattered, elevated Montgomery's glands

Aging woman

- Breasts look pendulous, flat, and sagging - Nipples may be retracted but can be pulled outward - On palpation, breasts feel more granular; terminal ducts around nipple feel more prominent and stringy - Thickening of inframammary ridge at lower breast is normal, and feels more prominent with age - Reinforce value of BSE - Women over 50 years old have increased risk of breast cancer - Older women may have problems with arthritis, limited range of motion, or decreased vision that may inhibit self-care - Suggest aids to self-examination; for example, talcum powder helps fingers glide over skin

Lactation

- Colostrum changes to milk production around the 3rd postpartum day - Breasts may become engorged, appearing enlarged, reddened, and shiny and feeling warm and hard - Frequent nursing helps drain ducts and sinuses and stimulate milk production - Nipple soreness normal, appearing around 20th nursing, lasting 24 to 48 hours, then disappearing - Nipples may look red and irritated; may even crack but will heal rapidly if kept dry and exposed to air; frequent nursings best treatment for nipple soreness

After the 4th month of pregnancy, what may appear?

- Colostrum may be expressed after fourth month - This thick yellow fluid is precursor for milk, containing same amount of protein and lactose, but practically no fat - Breasts produce colostrum for first few days after delivery

Gynecomastia

- Condition is usually unilateral and temporary - Reassurance is necessary for adolescent male, whose attention is riveted on his body image - Gynecomastia may reappear in aging male and may be due to testosterone deficiency

A decreased breast size in the older women makes what more prominent?

- Decreased breast size makes inner structures more prominent

Skin retraction

- Dimpling or a pucker when hands on hip

Maneuvers to screen for retraction

- Direct woman to change position to check breasts for skin retraction signs; first ask her to lift arms slowly over head; both breasts should move up symmetrically - Next ask her to push her hands onto her hips and then to push her two palms together; these maneuvers contract pectoralis major muscle; slight lifting of both breasts will occur - Ask woman with large pendulous breasts to lean forward while you support her forearms; note symmetric free-forward movement of both breasts

Inspect and palpate the axillae

- Examine axillae while woman is sitting - Inspect skin, noting any rash or infection; lift woman's arm and support it, so that her muscles are loose and relaxed; - Use right hand to palpate left axilla - Reach fingers high into axilla; move them firmly down in 4 directions - Move woman's arm through range-of-motion to increase surface area you can reach - Usually nodes are not palpable, although you may feel a small, soft, nontender node in central group - Note any enlarged and tender lymph nodes

Nipple retraction

- Flat and broader nipple look, like an underlying crater - recent retraction suggests cancer, which causes fibrosis of the whole duct system and pulls in the nipple. - May also occur with benign lesions such as ectasia of the ducts. - do not confuse with inversion, which has no broadening and isnt fixed

Inspect the breast

- General appearance - Skin - Lymphatic drainage areas - Nipple

Teaching Breast Self- Exam (BSE)

- Help each woman establish regular schedule of self-care - Advise pregnant or menopausal woman not having menstrual periods to select a familiar date to examine her breasts each month - Stress that self-examination will familiarize woman with her own breasts and their normal variation; emphasize absence of lumps (not the presence of them) - Encourage her to report any unusual finding promptly

Palpate the breasts

- Help woman to a supine position - Tuck a small pad under side to be palpated and raise her arm over her head to flatten breast tissue and displace it medially; any significant lumps will then feel more distinct - Use pads of your first three fingers and make a gentle rotary motion on breast; vary pressure palpating light, medium, and deep tissue in each location - Vertical strip pattern currently recommended to detect a breast mass, but two other patterns are in common use: - - From the nipple palpating out to periphery as if following spokes on a wheel - - Palpating in concentric circles out to periphery

Central axillary nodes

- High up in the middle of the axilla, over the ribs and serratus anterior muscle. - These recieve lymph from the other 3 groups of nodes.

How do you inspect and palpate the male breast?

- Inspect chest wall, noting skin surface and any lumps or swelling - Palpate nipple area for any lump or tissue enlargement; it should feel even, with no nodules - Palpate axillary lymph nodes

What is colostrum rich in?

- It is rich with antibodies that protect newborn against infection, so breastfeeding is important

The nipple

- Just below the center of the breast - Round, rough and usually protuberant - Surface looks wrinkled and indented with tiny milk duct openings

Where are the breasts located

- Lie anteriorly to the pectoralis major and serratus anterior muscles. - Located between the 2nd and 6th ribs, extending from the side of the sternum to the midaxillary line.

If you feel a lump or mass, note characteristics

- Location: as with clock face, describe distance in centimeters from nipple; or diagram breast in woman's record and mark in location of lump - Size: judge in centimeters in three dimensions: width, length, and thickness - Shape: state whether lump is oval, round, lobulated, or indistinct - Consistency: state whether lump is soft, firm, or hard - Movable: is lump freely movable or fixed when you try to slide it over chest wall? - Distinctness: is lump solitary or multiple? - Nipple: is it displaced or retracted? - Note skin over lump: is it erythematous, dimpled, or retracted? - Tenderness: is lump tender to palpation? - Lymphadenopathy: are any regional lymph nodes palpable?

Edema (peau d'orange)

- Lympatic obstruction produces edema - Thickens the skin and exaggerates the hair follicles, giving pigskin or orangle peel look - This condition suggests cancer. - Edema usually begins in skin around and beneath the areola, the most dependent area of the breast. - Nipple infiltration

Be selective in your choice of factual material, use:

- Majority of women will never get breast cancer - Great majority of breast lumps are benign - Early detection of breast cancer is important; if cancer is not invasive, survival rate close to 98%

Benign breast disease (formerly fibrocystic breast disease)

- Multiple tender masses - 6 diagnostic categories exist based on symptoms and findings: 1. swelling and tenderness 2. Mastlagia (pain) 3. Nodularity (lumps) 4. Dominant lumps 5. Nipple discharge 6. Infections and inflammations

What happens to the breasts during pregnancy?

- Pregnancy stimulates expansion of ductal system and supporting fatty tissue as well as development of true secretory alveoli - Thus breasts enlarge and feel more nodular; nipples are larger, darker, and more erectile - Areolae become larger and grow darker brown as pregnancy progresses, and tubercles become more prominent - Venous pattern prominent over skin surface

Premenstrual engorgement is normal from what?

- Premenstrual engorgement is normal from increasing progesterone - Consists of slight enlargement, tenderness to palpation, and generalized nodularity; lobes feel prominent and their margins more distinct

Breast abscess

The male breast

- Rudimentary structure consisting of a thin disk of undeveloped tissue underlying nipple - Areola well developed, although nipple is small

Note position of nipples on prepubertal child

- Should be symmetric, just lateral to midclavicular line, between fourth and fifth ribs - Nipple is flat, and areola is darker pigmented

Nipple

- Should be symmetrical on same plane on both breasts - Nipples usually protrude, although some are flat and some are inverted - Normal nipple inversion may be unilateral or bilateral and usually can be pulled out - Note any dry scaling, any fissure or ulceration, and bleeding or other discharge

Dimpling

- Sign of skin retraction - Cancer causes fibrosis, which contracts the suspensory ligaments - may be apparent at rest, with compression, or with lifting of the arms. - Distortion of areola as fibrosis pulls the nipple toward it.

Cancer

- Solitary, unilateral, nontender mass. - Single focus in one area, but can be interspersed with other nodules. - Solid, hard, dense, and fixed to underlying tissues or skin as cancer becomes invascive. - irregular borders and poorly delineated. - Grows constantly - Often painless - most common in upper outer quadrant - As cancer advances, signs include firm or hard irregular axillary nodes, skin dimpling, nipple retraction, elevation, and discharge

The areola

- Surrounds the nipple for a 1-2 cm radius - Contain small elevated sebaceous glands, called Montgomery's glands

How should palpation be performed during BSE?

- Teach woman to do this in front of a mirror while she is disrobed to waist - Supine position and in the shower where soap and water assist palpation.

The 15-20 lactiferous ducts form what?

- The 15-20 lactiferous ducts form a collecting duct system converging toward the nipple - There, the ducts form ampullae, or lactiferous sinuses, behind the nipple, which are reservoirs for storing milk.

Who has a higher incidence of breast cancer, whites or African American's?
