Q

What is the triple assessment?

A

Clinical assessment: symptoms, risk factors, family history particularly age, HRT and medications

Imaging assessment - if <40 USS, if >40 mammogram

Needle biopsy : core biopsy allows you to test for receptors etc as big chunk, fine needle aspiration of lymph nodes allows you to check for malignancy to see if axillary node clearance is indicated.

Q

when is radiotherapy indicated for breast cancer? type?

A

Whole breast radiotherapy is recommended after a woman has had a wide-local excision as this may reduce the risk of recurrence by around two-thirds.

For women who’ve had a mastectomy radiotherapy is offered for T3-T4 tumours and for those with four or more positive axillary nodes

Q

14
Q

Pharamcology tamoxifen

A

Tamoxifen is a selective oestrogen receptor modulator (SERM).

It either blocks or stimulates oestrogen receptors, depending on the site of action.

It blocks oestrogen receptors in breast tissue, and stimulates oestrogen receptors in the uterus and bones.

This means it helps prevent osteoporosis, but it does increase the risk of endometrial cancer.

Q

pharmacology aromatase inhibitors such as Anastrozole

A

Aromatase is an enzyme found in fat (adipose) tissue that converts androgens to oestrogen. After menopause, the action of aromatase in fat tissue is the primary source of oestrogen. Aromatase inhibitors work by blocking the creation of oestrogen in fat tissue

osteoporosis
NICE recommends a DEXA scan when initiating a patient on aromatase inhibitors for breast cancer
hot flushes
arthralgia, myalgia
insomnia

18
Q

what drug is used for HER2 +ve breast cancer?

what i main complication you need to monitor?

A

Trastuzumab (Herceptin)

a monoclonal antibody that targets the HER2 receptor. It may be used in patients with HER2 positive breast cancer. Notably, it can affect heart function; therefore, initial and close monitoring of heart function is required.

Pertuzumab (Perjeta)
Neratinib (Nerlynx)

19
Q

when is ‘neoadjuvanant’ chemotherapy used?

A

to downstage a primary lesion or after surgery depending on the stage of the tumour, for example, if there is axillary node disease - FEC-D is used in this situation.

A key reason for considering neo-adjuvant chemotherapy in breast cancer is to try to downsize the tumour before surgery and allow breast conserving surgery rather than mastectomy

20
Q

what is peau d’orange linked to

A

inflammatory breast cancer

21
Q

Looks like eczema of the nipple/areolar, spreads from nipple to areola
Erythematous, scaly rash

A

pagets disease of the nipple

22
Q

what are phyllodes tumours

A

Phyllodes tumours are rare tumours of the connective tissue (stroma) of the breast, occurring most often between ages 40 and 50. They are large and fast-growing. They can be benign (~50%), borderline (~25%) or malignant (~25%). Malignant phyllodes tumours can metastasise.

23
Q

blood supply of lattismus muscle ?

A

the thoracodorsal artery, and branch of the subscapular artery

24
Q

Young patient with firm mobile mass

A

fibroadenoma

25
Q

Soft, fluctuant swelling perimenopause

A

cyst

26
Q

recurrent infection/abscess in smoker

A

periductal mastitis

27
Q

nipple retraction and occasionally creamy nipple discharge

might be brown-green discharge

A

duct ectasia

28
Q

Bloody discharge with no lump

A

Intraductal papilloma

29
Q

obese/large breasts, following trauma Initial inflammatory response, the lesion is typical firm and round but may develop into a hard, irregular breast lump

A

fat necrosis

30
Q

management of fibroadenoma

A

If greater than 4cm - core biopsy to exclude a phyllodes tumour.

10% will increase in size, 30% regress and the remainder stay the same. This does not apply during pregnancy and lactation when they may increase in size substantially and subsequently sequester milk.

Management:
If want excision - circumareolar incision. Smaller lesions may be removed using a mammotom

31
Q

‘halo appearance’ on mammography.

A

cyst

32
Q

what type of scan helps confirm a cyst

A

USS - fluid filled

33
Q

first line management of mastitis

A
  1. continue breastfeeding
  2. If unwell etc. - flucloxacillin for 10-14 days
34
Q

treatment of periductal mastitis

A

co-amoxiclav

35
Q

Pathophysiology duct ectasia

A

Duct ectasia is a dilatation and shortening of the terminal breast ducts within 3cm of the nipple. It is common and the incidence increases with age. Associated with smoking

36
Q

management of duct ectasia

A

Patients with troublesome nipple discharge may be treated by microdochectomy (if young) or total duct excision (if older).

37
Q

Lumpiness
Breast pain or tenderness (mastalgia)
Fluctuation of breast size

A

fibrocystic breast change

38
Q

management fibrocystic breast change

A

Options to manage cyclical breast pain (mastalgia) include:
Wearing a supportive bra
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen
Avoiding caffeine is commonly recommended
Applying heat to the area
Hormonal treatments (e.g., danazol and tamoxifen) under specialist guidance

40
Q

management galactcele

A
