Prolactinoma

Causes of a Prolactinoma

Although pituitary tumor research continues to unravel the mysteries of disordered cell growth, the prolactinoma cause remains unknown. Most are sporadic, meaning they are not genetically passed from parents to offspring.
 

Symptoms of a Prolactinoma

The symptoms of prolactinoma can vary from person to person. Symptoms also vary, depending on the:
 
  • Size of the prolactinoma
  • Where the prolactinoma is located within the pituitary gland
  • Gender.
     
Prolactinoma symptoms caused by high prolactin levels can include:
 
  • Infertility.
     
  • Changes in menstruation. In some women, periods may disappear altogether. In others, periods may become irregular or menstrual flow may change.
     
  • Women who are not pregnant or nursing may begin producing breast milk.
     
  • Loss of libido (interest in sex).
     
  • Vaginal dryness and painful intercourse.
     
  • Headaches.
     
  • Eye problems caused by the enlarged pituitary pressing against nearby eye nerves.
     
These possible symptoms are not always a sign of a prolactinoma. Other medical conditions can cause these symptoms as well. A person experiencing symptoms should see his or her doctor so that the problem can be diagnosed and treated as quickly as possible.
