Q

Breast cancer

A
  • Breast cancer usually begins either in the cells of the lobules, which are milk-producing glands, or the ducts, the passages that drain milk from the lobules to the nipple
  • normally happens at age 30 or older, most commonly over 50
  • usually single, although may coexist with other nodules
  • irregular or stellate
  • firm or hard
  • not clearly delineated from surrounding tissues
  • may be fixed to skin or chest wall
  • usually no tender
  • Ask if it happened before or after menopause
  • either invasive or non-invasive

Q

non-invasive breast cancer

A
  • stays within the milk ducts or lobules in the breast

Q

How to palpate breasts, and how long should you spend on each breast?

A
  • Best position is when tissue is flattened
  • A thorough exam should take 3 minutes /breast.
  • Use fingertips with light, medium and deep pressure
  • Rectangular area
  • Bimanual palpation
  • concentric circles or spokes-on-a-wheel
17
Q

if any lumps are present, note (10 things):

A
  • Location – clock or quadrants
  • Size – width x length x depth
  • Shape – oval, round, lobulated
  • Consistency – soft, firm, hard
  • Mobility – movable, fixed
  • Distinctness – solitary or multiple
  • Nipple - displaced or retraction
  • Overlying skin – erythema, dimpling, retraction
  • Tenderness
  • Lymphadenopathy
18
Q

Fibroadenomas

A
  • solid, noncancerous breast tumors that occur most often in adolescent girls and women under the age of 30
  • Usually single, may be multiple
  • Round, disclike, or lobular
  • May be soft, usually firm
  • Well delineated
  • Very mobile
  • Usually nontender
  • need biopsy but not cancerous
  • might feel like a marble in the breast, moving easily when touched
  • Treatment may include monitoring to detect changes in the size or feel of the fibroadenoma, a biopsy to evaluate the lump, or surgery to remove it
19
Q

Fibrocystic breast disease

A
  • Common way to describe painful, lumpy breasts
  • Age 30-50, regress after menopause except with estrogen therapy
  • Single or multiple
  • Round
  • Soft to firm, usually elastic
  • Well delineated
  • Mobile, often tender
  • can cause discomfort especially if too much caffeine or chocolate
20
Q

Edema (Peau d’orange)

A
  • a mammographic pattern of skin thickening, increased parenchymal density, and interstitial marking
  • skin looks like an orange peel
21
Q

nipple retraction

A
  • If nipple retraction is something new, that would be a concern
  • If it’s always been inverted, that’s not as much as a problem
22
Q

Mastalgia

A
  • pain in the breast

- Can come from trauma, inflammation, infection, then benign breast disorders

23
Q

what should the breasts feel like?

A
  • Firm, smooth, elastic if a woman has never had a baby
  • Premenstrual engorgement/enlargement is common due to increased progesterone
  • Under the breast, the tissue gets compressed together over time, so you can feel an inframammary ridge
  • In large-breasted woman, it’s a good idea to do a bimanual examination
24
Q

anatomical details of breast exam

A

The glandular tissue of the breast is suspended within the superficial fascia of the anterior chest wall, extending roughly from the second to the sixth or seventh anterior intercostal space and from the edge of the sternum to the midaxillary line. About two-thirds of it rests upon the fascia covering the pectoralis muscle and the rest upon the fascia of the serratus anterior muscle. Toward the axilla, the axillary tail of Spence passes through an opening in the pectoral fascia, the foramen of Langer, into the axilla.

25
Q

checking Male breast for cancer

A
  • Inspect the chest wall noting skin surface and any lumps or swelling
  • Palpate the nipple: It should feel even with no nodules.
  • The normal male has a flat disk of undeveloped breast tissue beneath the nipple
26
Q

Gynecomastia

A

an enlargement of this breast tissue in men/boys. It feels like a smooth firm movable disk. common during adolescence, usually unilateral and temporary.

27
Q

what is the Tail of Spence?

A

superior lateral corner of the breast tissue – most common place for breast cancer to develop

28
Q

Where is the female breast located?

A

located between the 2nd and 6th rib, from the side of the sternum to the middle of the axilla

29
Q

nipple retraction with distortion

A

Retraction with distortion is when suspensory ligaments have gotten tightened up from cancer and are pulling in on the breasts (also could be a scar)

30
Q

When should you perform the breast exam in relation to the menstrual cycle?

A

5 days after start of menstrual cycle

31
Q

What is the function of the breast?

A

To produce milk

32
Q

what is fibrous breast tissue (including suspensory ligaments)?

A

Cooper’s ligaments: fibrous bands that extend vertically from the surface to attach on the breast wall (become contracted in cancer of the breast - producing pit or dimples

33
Q

What kind of tissue are the lobes embedded in in the breast

A

adipose

34
Q

More than 75% of lymphatic drainage from the breast goes in to…

A

ipsilateral axillary area

35
Q

What are supernumerary nipples?

A

common minor congenital malformations that consist of nipples and/or related tissue in addition to the nipples normally appearing on the chest. Supernumerary nipples are located along the embryonic milk lines

36
Q

Are black women or white women more likely have breast cancer?

A

Black women – largely b/c of diagnosis at a later age

37
Q

70% of breast cancers occur in women that have…

A

no identifiable risk factors except their gender or age
