Hello, Thanks for the query. I can understand your concern. Your pathology is called gynecomastia and needs a careful clinical and lab. evaluation. Usually it is common in adolescence, in your age should be tried to find a cause and treated accordingly. A serum chemistry panel may be helpful in evaluating for renal or liver disease. Free or total testosterone, luteinizing hormone (LH), estradiol, and prolactin levels are used to evaluate gynecomastia. Obtain thyroid-stimulating hormone (TSH) and free thyroxine levels if hyperthyroidism is suspected. In case you need more explanations, i would be happy to help. Thanks
