Q

How does Anastrozole work?

A

Aromatase inhibitor

It inhibits the enzyme aromatase and hence reducing the conversion of androgens into oestrogens in peripheral tissues. This is the main source of oestrogen production in postmenopausal women, compared to pre-menopausal women, where the main source of oestrogen is the ovaries.

Q

How does Tamoxifen work?

A

Its a selective oestrogen receptor modulator, meaning it antagonises oestrogen receptors on the breast cancer cells and blocks the anabolic effects of oestrogen.

Q

How do you do a sentinel lymph node biopsy?

A

A radioactive substance and/or blue dye is injected near the tumour. During the surgery a probe is used to locate the lymph nodes containing the radioactive substance so they can be excised.

Q

What is breast involution?

A

Process by which the breast epithelial tissue is gradually lost with aging of the mammary gland.

Mammary glands are lost as they are now redundant

Q

How do you distinguish between ductal and lobular carcinoma on a mammogram?

A

Calcification is seen more in ductal than lobular - hence it is more visible on mammogram

25
What are the treatments available for duct ectasia?
None needed - reassurance Microdochectomy - if condition is bothering patient and they are younger Total duct excision - if symptomatic and bothering the patient and they are older
26
What is a microdochectomy?
A procedure to remove one or more of the milk ducts from your breast
27
What is Total Duct excision?
Removal of a disc of duct tissue from behind the nipple
28
What is a side effect of Aromatase inhibitors?
Osteoporosis
29
What are side effects of SERMs ( Selective Oestrogen Receptor Modulators) i.e Tamoxifen?
Amenorrhoea Endometrial cancer Vaginal bleeding VTE
30
What is another name for Herceptin?
Trastuzumab
31
What is the appropriate management for fibroadenomas that are >3cm?
Surgical excision biopsy
32
What would be a reasonable indication for surgical excision if a fibroadenoma was <3cm ?
Cosmesis ( Aesthetic/ Body image issues)
33
What is a Phyllodes tumour?
Rare breast tumour that starts in the connective tissue ( fatty tissue, ligaments around area) rather that the ducts or lobules. Most are benign A fibroepithelial lesion ( stroma and epithelial components )
34
What is Paget's disease of the nipple?
Reddening Thickening May resemble eczema ( itchy, crusty) Inverted nipple Affects nipple first then areola It is associated with underlying breast malignancy
35
How does eczema spread on the nipple?
Areolar then to the nipple
36
What is FIbroadenosis?
Fibrocystic breast disease Most common in middle-aged women 'Lumpy' breasts which may be painful. Symptoms may worsen prior to menstruation
37
What is Duct Papilloma?
Local areas of epithelial proliferation in large mammary ducts May present with blood stained discharge
38
What is Fat necrosis?
More common in obese women with large breasts May follow trivial or unnoticed trauma Initial inflammatory response, the lesion is typical firm and round but may develop into a hard, irregular breast lump
39
What is a breast abscess?
More common in lactating women Red, hot tender swelling Can result from mastitis
40
What is a key reason for Neo-Adjuvant Chemotherapy?
Try to downsize the tumour before surgery and allow breast conserving surgery rather than mastectomy. Reduce peri-operative risks Better cosmetic outcome
41
What do Breast Cysts show on mammogram?
Halo appearance
42
What treatment is required following a wide local excision?
Whole breast radiotherapy Then Anastrozole, Tamoxifen or Herceptin can be used as maintenance therapy following the radiotherapy
43
What sign on ultrasound indicates extracapsular breast implant rupture?
Snowstorm sign of axillary lymph nodes Leakage of silicone is drained by lymphatic system
44
Who is breast cancer screening offered to?
All women age 50-70 every 3 years
45
A 52-year-old woman with early-stage breast cancer is undergoing breast-conserving surgery. During the procedure, the sentinel lymph node biopsy reveals two nodes with micrometastatic involvement. There are no clinical signs of further axillary disease, and the patient is scheduled for adjuvant radiotherapy. Considering these findings, what is the most appropriate next step?
Close without additional axillary surgery Micrometastases or 2 micrometastases on sentinel lymph node
46
What is Triple Negative breast cancer?
A type of breast cancer that does not have any of the receptors ( Oestrogen, Progesterone, HER2 )
47
Who is Periductal Mastitis common in?
Smokers
48
What age is screening with a mammogram as opposed to an US used?
Over 35 - more dense breast tissue
49
What nerve injury can be a complication of axillary node clearance?
Brachial Plexus injury
50
What treatment is recommended for Triple Negative breast cancer?
Aggressive Neoadjuvant chemo Lumpectomy/Mastectomy Adjuvant chemo/radiation
51
What is cyclical mastalgia?
Breast pain associated with menstrual cycle
52
What is the treatment for Fat Necrosis?
Conservative as in most cases the body will break it down over time Safety net - gets bigger or other breast changes come back
53
What is a radial scar?
A radial scar is a benign breast condition which can mimic a breast carcinoma. It describes idiopathic sclerosing hyperplasia of the breast ducts. Patients are typically asymptomatic, and it is usually picked up incidentally. A mammogram typically shows a star or rosette-shaped lesion with a translucent centre.
54
What should be monitored before and during usage of Herceptin?
Cardiac function - causes cardiotoxicity
55
What is a Galactocele?
A breast lesion most commonly occurring in women who have recently ceased breastfeeding. Milk builds up and stagnates within the lactiferous ducts, leading to the formation of a mobile, cyst-like lesion which can be tender.
56
What are risk factors for breast cancer?
Increased hormone exposure (Early menarche or late menopause Nulliparity or late first pregnancy Oral contraceptives or Hormonal Replacement Therapy) BRCA1/BRCA2 Older White Obesity Alcohol/Smoking Family Hx
57
What is a Seroma?
A localised accumulation of fluid beneath the skin surface
58
What is recommended in any woman who undergoes a WLE?
Adjuvant radiotherapy If ER+ , Tamoxifen or Anastrozole (Post-Menopasual) would also be given If HER2 + , Herceptin would also be given
