What is gynecomastia?

Gynecomastia refers specifically to the enlargement of breast tissue in males. This condition can occur due to hormonal changes, such as an imbalance between testosterone and estrogen, which can happen during puberty, aging, or as a side effect of certain medications. It's characterized by the presence of glandular tissue under the nipple area, which can cause concern or discomfort for those affected.

Understanding gynecomastia is crucial because it distinguishes between related conditions and symptoms. For instance, swelling of the testicles pertains to a different issue concerning the male reproductive system, while breast pain is a symptom that could arise from various conditions, including trauma or inflammation, but does not specifically define gynecomastia. The development of breast cancer is a serious concern but is distinctly different from gynecomastia, which is a benign condition related to tissue growth rather than malignancy.
