What is Gynaecomastia?
Gynaecomastia is a medical term for enlarged breast(s). It is usually used in reference to men who have abnormal breast development as a result of hormonal imbalances or drug side effects. It is also a condition associated with occupational exposure to oestrogen dust, feeding of refugees, and ingestion of tainted food.
Causes of Gynaecomastia:
The most common reason is the onset of puberty in teenage boys, when there may be a temporary hormone imbalance. Male breasts sometimes enlarge in old age, with an increase in weight, and with oestrogen hormone treatment in men wanting to change sex. It may also be a symptom of a significant underlying disease including cirrhosis of the liver, cancer in the adrenal glands, overactivity or cancer of the thyroid gland, an uncommon form of lung cancer, a tumour in the testicles or a genetic condition called Klinefelter syndrome in which there is an extra sex chromosome.
