Q

The breast can be macroscopically divided into two main parts.

A

The glandular component is the first of these and is concerned with
milk production. The second part consists of all the other tissues that make up and support the breast. These include fat, fascia (connective tissue), and muscles.

Q

JUST SOME KNOWLEDGE: These are drained by a network of small ducts (intralobular ducts) which come together to form a single duct draining each
lobule (interlobular duct). The interlobular ducts in turn join to form intralobar ducts which jointly form a single lactiferous duct which drains that lobe. The purpose of the ducts is to transport milk; the lactiferous ducts dilate just under the nipple to form the lactiferous sinus or ampulla and then narrow and terminate at the surface of the nipple. The lobes are separated by fibrous septae and connective tissue stroma

HEEHEE

20
Q

Over 90 % of breast carcinomas originate in these units as do many benign breast diseases.

A

TDLU(TERMINAL DUCTAL LOBAR UNIT)

21
Q

is a term used to describe a cancer that starts in the lining layer (epithelial cells) of organs like the breast.

A

carcinoma

22
Q

Nearly all breast cancers are

A

carcinomas

23
Q

Most are the type of carcinoma that starts in glandular tissue called

A

adenocarcinoma

24
Q

is a benign (non-cancerous) breast condition in which the lobules (milk-producing glands) are enlarged, and there are more glands than usual. It is often found in biopsies of women who have fibrosis or cysts in their breasts.

A

Adenosis

25
Q
  • is a special type of adenosis in which the enlarged lobules are distorted by scar-like tissue. This type may cause breast pain.
A

Sclerosing adenosis

26
Q

it is the transformation of breast epithelial cells into an apocrine or sweat‐gland type of cells, often occurs in the peripheral parenchyma, particularly among premenopausal women and it is usually associated with gross cysts in fibrocystic breast disease, the most common non‐cancerous disease of the breast.

A

Apocrine metaplasia -

27
Q
  • are a benign (not cancer) condition. They’re one of the most common causes of a breast lump and can develop in either one or both breasts. It’s thought they develop naturally as the breast changes with age due to normal changes in hormone levels.
A

Breast Cysts

28
Q

are two common, closely related, non-cancerous
conditions that often develop together in the breast.

A

Columnar cell change and Columnar cell hyperplasia

29
Q
  • nonneoplastic alteration characterized by spherules of basement membrane material surrounded by myoepithelial cells
A

Collagenous spherulosis -

30
Q

-, is a benign (non-cancerous) breast condition that occurs when a milk duct in the breast widens and its walls thicken.

A

Duct Ectasia

31
Q
  • is a pathological entity encountered when breast biopsies are done for investigation
    of punctate or amorphous calcifications. involves the terminal ductal and lobular units (TDLU’s).
A

Columnar alteration with prominent apical snouts and secretions (CAPSS)

32
Q

, wart-like tumors that grow within the milk ducts of the breast. They are made up of gland tissue along with fibrous tissue and blood vessels (called fibrovascular tissue

A

Intraductal Papilloma’s of the Breast -

33
Q

it occurs when one breast has a different size, volume, position,
or form from the other.

  • A common abnormality seen on mammogram
A

Breast Asymmetry

34
Q
  • is a condition in which the nipple is pulled inward into the breast instead of pointing outward.
A

Inverted Nipples

35
Q

Inverted Nipples are aka

A

nipple inversion, nipple retraction, or invaginated nipple,

36
Q
  • tissue is a relatively common congenital condition in which abnormal accessory breast tissue is seen in addition to the presence of normal breast tissue.
  • can be found anywhere along the thoracoabdominal region of the milk line (the embryologic mammary streak) but are most frequently found in the axilla and may occur bilaterally.
A

Accessory breast tissue

37
Q

– it come in different shapes and sizes.
Normal breast tissue can sometimes feel lumpy.

A

Lumps

38
Q

can be a sign of a serious form of cancer known
as inflammatory breast cancer.

A

Dimpling

39
Q

dimpling of the breast causes the skin to look like

A

pitting and uneven skin of an orange. Sometimes, the skin can also be red and inflamed.

40
Q

Also known as peau d’orange

A

A

mastalgia

Q

swelling caused by a
build-up of fluid in the body’s tissues.
- is a long-term condition, which means that once it has developed it can be controlled but is unlikely to ever go away completely.

A

Lymphoedema

Q

Breast Changes During Your Lifetime That Are Not Cancer

A

2. During pregnancy
3. As you approach menopause

5. After menopause
