Pituitary tumours: Types of tumours and symptoms
Prolactin-producing tumours (Prolactinomas)
Figure 2: Abnormal secretion of breast milk (galactorrhea)
Prolactin-producing tumours make too much of a hormone called ”prolactin”. These tumours are called “prolactinomas.”
Women with a prolactinoma may:
- stop having their menstrual period
- produce some breast milk (a condition called “galactorrhea”, see Figure 2)
- become infertile (unable to have babies)
Men with a prolactinoma may:
- get headaches
- have problems with sexual desire or function
- lose peripheral vision (off to the sides) and only see straight forward.
Medicine can reverse these effects. Prolactinomas respond to medicine and rarely need surgery.
