1

def

a benign tumour in the breast formed of mixed fibrous and glandular tissue

2

what are fibroadenomas also called

breast mice or breast mouse due to their high mobility in the breast

3

aetiology

partially hormone-related
therefore fibroadenomas are common during reproductive years, they may enlarge during pregnancy or with hormone therapy, and may shrink after menopause

4

what is associated with lower frequency of fibroadenomas

more healthy lifestyle, including fruit + veg, exercise and the OCP

5

epi

common in women of reproductive age (adolescent girls and women)

6

history + examination

a slowly growing lump in the breast of a woman of child-bearing age
the lump is round with distinct borders, mobile, firm and rubbery, and painless

7

investigations

all breast lumps should undergo the 'triple assessment'
1 clinical examination
2 radiology (USS <35yrs, mammography + USS >35yrs)
3 histology/cytology with a needle biopsy

8

what mutation is assoociated with fibroadenoams

mediator complex subunit 12 (MED12)

9

what is a solid mass in the breast and a fluid-filled mass in the breast likely to be

solid mass - fibroadenoma
fluid-filled mass - cyst

10

management

the usual management is to reassure and discharge the patient, however regular monitoring with breast USS is recommended
surgical options are considered if any components of the triple assessment give abnormal findings
1 lumpectomy or excisional biopsy
-removal of breast tissue which is used to check for cancer
2 cryoablation
-freezing fibroadenoma

11

complications

complications of surgery include new fibroadenoma formation
only complex fibroadenomas increase risk of breast cancer

12

what are the two different type of fibroadenoma

simple
complex

13

what is a complex fibroadenoma

a fibroadenoma which contains epithelial calcifications or cysts

14

prognosis

regular checkups are recommended
fibroadenomas may shrink post menopause
good prognosis

15

where in the breast do fibroadenomas commonly arise

terminal duct of lobular unit of breast

16

how large are fibroadenomas

majority are less than 3cm in diameter
