1

What happens to breasts before menarche?

Increase in the number of lobules in the breast and increased volume of interlobular stroma

2

How might breast conditions present?

Pain
Palpable mass
Nipple discharge
Skin changes
Lumpiness

3

What type of breast masses are most worrying?

Hard, craggy and fixed

4

What are potential causes of palpable masses in the breast?

Invasive carcinoma
Fibroadenomas
Cysts

5

When is nipple discharge most concerning?

If spontaneous and unilateral

6

What type of pathology does milky nipple discharge suggest?

Endocrine disorders eg. pituitary adenoma, side effect of medicine (OCP)

7

WHat does bloody or serous nipple discharge suggest?

Benign lesions eg. papilloma, duct ectasia, occasionally malignant lesions

8

Who is invited to have mammography screening and how often?

47-53 year olds every 3 years

9

What are worrying findings in mammography?

Densities - invasive carcinomas, fibroadenomas, cysts
Calcifications - ductal carcinoma in situ (DCIS), benign changes

10

What is the most common benign breast tumour?

Fibroadenoma

11

What type of tumours does mammographic screening increase detection of?

Small invasive tumours (hard to feel)
In situ carcinomas

12

WHen do fibroadenomas commonly occur?

<30 years
Can occur at any age

13

When do phyllodes tumours commonly occur?

Most present in 6th decade

14

When does breast cancer most commonly occur?

Rare before 25years (except for some familial cases)
Incidence increases with age
77% occur in women >50 years
Average age at diagnosis is 64 years

15

Name some disorders of development.

Milk line remnants
Polythelia
Accessory axillary breast tissue

16

Name some inflammatory disorders of the breast.

Acute mastitis
Duct ectasia
Fat necrosis

17

What is acute mastitis?

Usually a Staph aureus infection from nipple cracks and fissures
Erythemous painful breast, often pyrexia
Almost always occurs during lactation

18

What may be a complication of acute mastitis?

May produce breast abscesses

19

How is acute mastitis treated?

Expressing milk
Antibiotics

20

What is duct ectasia?

Duct dilation and inflammation of uncertain aetiology
My have periareolar mass and/or nipple discharge
Can mimic carcinoma
Often in patients in 50/60s

21

How does fat necrosis present?

Presents as a mass, skin changes or mammographic abnormality
Often history of trauma or surgery
Can mimic carcinoma clinically and mammographically

22

Name some benign lesions.

Fibrocystic change
Epithelial hyperplasia
Papilloma

23

How do fibrocystic changes commonly present?

Mass or mammographic abnormality which often disappears after aspiration with a fine needle (FNA)

24

What is the histology of fibrocystic change?

Cyst formation
Fibrosis
Apocrine metaplasia

25

How is epithelial hyperplasia usually detected?

Mammographic abnormality or as incidental fining in biopsies

26

What is epithelial hyperplasia?

Proliferation of epithelial cells which fill and distend ducts and lobules
Associated with a slight increased risk of carcinoma (even higher if atypical)

27

Where are large duct papillomas commonly found?

Lactiferous ducts near nipple

28

Where are small duct papillomas commonly found?

Often multiple and situated deeper in the breast

29

What type of papillomas are associated with increased risk of carcinoma?

Small duct papillomas

30

How do papillomas commonly present?

Nipple discharge (may be bloody)
Small palpable mass
Mammographic abnormality
