Galactorrhoea

 

Characterised by a large amount of milky discharge from multiple ducts.

Management

  • History/examination to consider cause: physiological, drugs, thyroid disorder, pituitary tumour (visual field defects/ new headaches) / prolactinoma (menstrual disturbance/acne)
  • Check serum prolactin/TSH   
    • For serum prolactin the upper end of normal range is 496 mU/L in women and 324mU/L in men
    • Raised prolactin levels are common (e.g. due to higher dose COCP or stress).
    • In prolactinoma a very high value (over 1000 and usually several 1000mU/L) is expected.
  • If a patient has a very high serum prolactin and is not pregnant or breast feeding consider referral to Endocrinology not to breast surgery
