Gynecomastia in Men HF#7074

 

Gynecomastia is an enlargement of breast tissue in males.  A man may feel an area of firm, glandular tissue in one or both breasts.  The breast may become enlarged and tender.  A man with gynecomastia may describe his breast as feeling rubbery or firm.  It occurs in babies, teens, and men.

Gynecomastia is often found during a physical exam.  Most of the time, no treatment is needed.  This condition will go away with time.  Your doctor may recommend a mammogram or ultrasound of the breast.  If breast cancer is suspected, you may need a biopsy of your breast.  You may have lab tests done to look at your hormone levels and overall health.  Your doctor may stop the use of certain medicines.  A surgical consultation may be part of your work up.

 

When gynecomastia occurs in men, it is often caused by medicine, disease, or hormone changes.

 

  • A lack of testosterone and an increase in estrogen may be one cause.  Your doctor may prescribe treatment with hormones.
  • The thyroid does not work as it should.
  • Your doctor will ask for a list of medicines you are taking.  Some medicines that cause this problem fall into these groups:
    • Heart.
    • Steroids.
    • Anti-epileptic.
    • Anti-depressants.
    • Anti-ulcer.
  • The use of alcohol, marijuana, and other "street" drugs may be a cause.
  • In rare cases, breast cancer may be the cause of breast tissue growth. 

Please follow up with your doctor for further treatment.
