- Endocrine disorders e.g. hypothyroidism, PCOS
- Medications e.g. Dopamine antagonists
- PREGNANCY!
Investigations:
- Pregnancy test!!
- Blood tests inclu. serum prolactin, renal, liver and thyroid tests
- MRI scan (first line for pituitary tumours)
Management:
Target underlying cause
- Dopamine agonists e.g. Bromocriptine
- Transsphenoidal removal of pituitary tumour
List 3 hormones that inhibit the production of prolactin (for lactation)
- High oestrogen (high during pregnancy)
- High progesterone (high during pregnancy)
- Dopamine (some medications block this)
State the presentation of galactorrhoea plus additional symptoms they may present with as a result of LH / FSH suppression

- Staphylococcus aureus
Presentation:
- Unilateral breast pain
- Erythema
- Warmth
- Nipple discharge
- Fever
Management:
- Advise to continue breastfeeding
- Conservative e.g. warm compress, analgesia
- Antibiotics if infected
Suggest which antibiotics should be used in lactational mastitis
Flucloxacillin (Erythromycin if penicillin allergy)
Suggest which antibiotic should be used in lactational mastitis if candidal infection is suspected
Fluconazole - but needs to be given to both the baby and mother (otherwise infection will reoccur)
Breast abscess - state the following:
- Pathophysiology
- Risk factors
- Common organism
- Presentation

Pathophysiology:
- Collection of pus within an area of the breast, commonly a bacterial infection
- Either a lactational (associated with breastfeeding) or non-lactational abscess (unrelated to breastfeeding)

- Smoking
- Breastfeeding
- Damaged nipple surface
- Underlying breast disease
Common organism:
- Staphylococcus aureus (most common)
Presentation:
- Acute presentation of a swollen, fluctuant tender lump (fluid filled)
- Generalised symptoms of infection e.g. fever
Management:
- Depends on whether lactational or non-lactational mastitis
- Lactational mastitis = conversative management, may need antibiotics (Flucloxacillin)
- Non-lactational mastitis = conversative management, may need broad-spectrum antibiotics (Co-Amoxiclav)
Abscess:
- Ultrasound
- Drainage
- Antibiotics / MCS
Outline some risk factors for breast cancer
- Female gender
- Smoking
- Family history
- Obesity
- HRT
- Oral contraceptive
- Prolonged lifetime oestrogen exposure
- Previous breast cancer

- Localised or widespread?
- Presentation?
- Detectable on mammogram?
- Potential to spread?
- Prognosis?
Type of cell affected?
- Epithelial cells of the breast ducts
Localised or widespread?
- Localised to single area
