Q

Why is it important to ask about breast trauma?

Q

Why is it important to ask about the relationship between the changing size of the breast lump and the patient’s menstrual cycle?

Q

What does tethering of the skin over the lump suggest?

A

Carcinoma until proven otherwise

19
Q

Describe the character of the discharge in Breast Carcinoma

A

Bloody

20
Q

Describe the character of the discharge in Intraductal Papilloma

A

Serous or seranguinous

21
Q

Describe the character of the discharge in Periductal Mastitis

A

Yellow, green, brown

22
Q

Describe the character of the discharge in Galactocoele

A

Milky

23
Q

Define duct ectasia.

A

A condition in which the lactiferous ducts become blocked or clogged

24
Q

Why is it important to check whether the patient is otherwise fit and well?

A

Most patients with breast lumps don’t have an other symptoms
Patients with infective/inflammatory causes of breast lump (e.g. mastitis, abscess) may experience fever
NOTE: breast cancer rarely leads to systemic signs of malignancy

25
Q

List some key features of inspection of the breasts.

A

Asymmetry
Contours
Skin changes
Nipple discharge

26
Q

List some skin changes of the breast that you should look out for.

A
Erythema 
Ulceration
Peau d’orange 
Tethering
Radiotherapy tattoos
27
Q

Describe what a solitary cyst feels like on palpation

A

Smooth surface + distinct border + firm to lax

NOTE: feels similar to fibroadenoma

28
Q

Describe what benign cystic change feels like on palpation

A

Irregular surface + indistinct borders + mixed consistency

29
Q

Describe what a fibroadenoma feels like on palpation

A

Smooth surface + distinct borders + rubbery + mobile

30
Q

Describe what a carcinoma feels like on palpation

A

Irregular surface + indistinct borders + hard

Tethering?
Lymphadenopathy?

31
Q

What are the components of triple assessment?

A

Clinical examination
Radiological examination
FNA and core biopsy

32
Q

Which types of radiological assessment of the breast lump are offered to patients?

A

< 35 years = ultrasound
35+ years = two-view mammogram
NOTE: younger women do not get mammograms because their breast tissue is more dense and it is difficult to identify masses

33
Q

What is the difference between an FNA and a core biopsy?

A

FNA – samples cells for cytology

Core biopsy – samples tissue for histology

34
Q

Describe the management of fibroadenomas.

A

Benign condition that will resolve over several years

Can be removed by excisional biopsy

35
Q

What are the four most common sites of metastasis of breast cancer?

A

Liver
Bone
Lungs
Brain

36
Q

Describe the treatment options for breast cancer.

A

Local Treatments: Radiotherapy + Surgery

Systemic Treatments: Chemotherapy + Hormonal Therapy + Monoclonal Antibodies

37
Q

Describe the typical presentation of a patient with a breast abscess.

A

Sudden appearance of a painful lump
Usually in middle-aged smokers
Fever, skin erythema and tethering may also be found

38
Q

What important risk factor is strongly associated with breast abscess and non-lactational mastitis?

A

Smoking

39
Q

How are breast abscesses treated?

A

Incision and drainage

Antibiotics

40
Q

Describe the typical presentation of breast cysts.

A

Well-circumcribed lump with a smooth surface and firm texture (may be painful)

41
Q

How can cysts and fibroadenomas be distinguished?

A

Ultrasound
Cysts will be hypoechoic
Fibroadenomas will be hyperechoic
NOTE: when cysts are drained, the fluid will be green, brown or yellow

42
Q

What is gynaecomastia?

A

Enlargement of the breasts in males, either due to hormone imbalance or drug therapy

43
Q

List some pathological causes of gynaecomastia.

A

Liver disease
Drugs (e.g. spironolactone, cimetidine, finasteride)
Primary testicular failure (e.g. bilateral cryptorchidism)
Acquired testicular failure
Secondary testicular failure (e.g. panhypopituitarism)
Endocrine tumours (e.g. testicular, adrenal, pituitary)
