Ultrasound in younger women, for those with denser breasts

43
Q

When is MRI used in breast cancer assessment?

A

Screening in women with high risk of breast cancer, and further assess size and features

44
Q

How is the lymph nodes assessed in breast cancer?

A

Ultrasound of the axilla and ultrasound guided biopsy. SLNB can be done in surgery

45
Q

Where is breast cancer most likely to spread to?

A

2Ls and 2Bs: lungs, liver, bones, brain

46
Q

What is a potentially complication of axillary clearance?

A

Chronic lymphoedema

47
Q

What is the possible management of chronic lymphoedema?

A

Massage techniques, compression bandages, weight loss

48
Q

What are potential s/e of radiotherapy in women with breast cancer?

A

Fatigue, local skin and tissue irritation and swelling, fibrosis of breast tissue, shrinkage of breast tissue, longer term colour changes

49
Q

What is the hormone treatment of patients with ER+ve breast cancer?

A

Tamoxifen in premenopausal, and aromatase inhibitors in post menopausal women (letrozole, anastrozole)

50
Q

How does tamoxifen work?

A

Selective oestrogen receptor modulator. It blocks/stimulates oestrogen receptors depending on the site: blocks in the breast, stimulates in uterus and bone

51
Q

How does aromatase inhibitors work?

A

Blocks the conversion of androgens to oestrogen in post menopausal women

52
Q

What is the screening follow up in patients who have had breast cancer?

A

Surveillance mammograms yearly for 5 years

53
Q

What is the management of a woman with breast cancer who has no palpable axillary lymphadenopathy at presentation?

A

Pre operative ultrasound; if this is negative, SLNB

54
Q

What is the management of patients who present with clinically palpable lymphadenopathy?

A

ALNC

55
Q

When is radiotherapy recommended?

A

When a woman has had a WLE

56
Q

What biological therapy is used in HER2 positive cancers?

A

Herceptin (trastuzumab)

57
Q

When is herceptin C/I?

A

Patients with a hx of heart disorders

58
Q

What are s/e of tamoxifen?

A

Menstrual disturbance, hot flushes, VTE, endometrial cancer

59
Q

What scan should be done when a patient is started in letrozole/anastrozole?

A

DEXA: due to increased risk of osteoporosis

60
Q

What is the likely diagnosis in a woman over 40 with lumpy, painful breasts before menstruation?

A

Fibroadenosis (fibrocystic disease)

61
Q

What is mammary ductal ectasia?

A

Dilation of the large ducts of the breast, which causes inflammation of the ducts and discharge

62
Q

What population is mammary duct ectasia most common in?

A

Perimenopausal women

63
Q

What is a significant risk factor for mammary duct ectasia?

A

Smoking

64
Q

What is the assessment of ductal ectasia?

A

Triple (assessment, imaging, biopsy)

65
Q

What is duct papilloma?

A

A warty lesion that growth in the ducts of the breasts due to proliferation of epithelial cells

66
Q

What is the typical presentation of intraductal papilloma?

A

Clear or blood stained nipple discharge. No lump

67
Q

Other than triple assessment, what investigations can be done for ductal ectasia + ductal papilloma?

A

Ductography: injecting contrast into the abnormal duct and performing mammograms to visualise the duct

68
Q

What is the tx of intraductal papillomas, and what must be checked?

A

Intraductal papillomas require complete surgical excision. After removal, the tissue is examined for atypical hyperplasia or cancer that may not have been picked up on the biopsy.

69
Q

What is galactorrhoea?

A

Breast milk production not associated with pregnancy or breast feeding

70
Q

What drugs can cause galactorrhoea and why?

A

Dopamine antagonists (eg, antispychotics). Due to dopamin blocking the secretion of prolactin

71
Q

What drugs can cause prolactin secretion and galactorrhoea?

A

Dopamine agonists (e.g., bromocriptine or cabergoline)

72
Q

What hormone stimulates breast milk production?

A

Oxytocin

73
Q

What hyperprolactinaemia also present with and why?

A

Menstrual irregularities, reduced libido, erectile dysfunction, gynaecomastia. Due to prolactin suppressing GnRH, reduces LH + FSH

74
Q

What genetic condition are prolactinomas associated with?

A

Multiple endocrine neoplasia (MEN) type 1

75
Q

What are differential causes of nipple discharge?

A

Galactorrhoea, hyperprolactinaemia, mammary duct ectasia, carcinoma, intraductal papilloma

76
Q

What investigations should all patients with nipple discharge get?

A

Triple assessment

77
Q

What is mastitis?

A

Inflammation of the breast tissue associated with breast feeding

78
Q

What are the features of mastitis?

A

Painful, tender, red hot breast, fever, general malaise

79
Q

What is the first line management of mastitis?

A

Continue breast feeding

80
Q

When should mastitis be treated with abx?

A

If systemically unwell, nipple fissure present, symptoms not improving, or if culture indicates infection

81
Q

What is the first line abx for mastitis?

A

Oral flucloxacillin for 10 days (s.aureus most common cause)

82
Q

What is the difference between duct ectasia and periductal mastitis?

A

Duct ectasia is a normal varient of breast involution, and is seen in many older women. Periductal mastitis is in younger women, associated with smoking, and treated with abx

83
Q

What is the most common cause of breast abscess?

A

S.aureus

84
Q

What is the treatment of breast abscess?

A

Abx, US guided aspiration, surgical debridement if necessary
