Patient question: I am a male, a month ago I found my left breast enlargement and thickening, went to the hospital to do an ultrasound, which showed that it was breast enlargement, the doctor let the liver function test, liver function is all normal (the checklist can not be found, the indicators are normal), the doctor finally said that it is an endocrine disorder, there is no medicine to cure, maybe after a while it will be fine. I want to ask men also breast enlargement? How can I treat it? There is no sign of it getting smaller yet. Li Huan replied: 1, consider estrogen increase or inactivation abnormalities, the main reasons are: liver function abnormalities lead to the body’s estrogen is not transformed and accumulated down (you have checked can be ruled out) estrogen increase in food (consider whether you have eaten some special supplements?) 2. If you have nipple discharge, you should also check the head CT to exclude hypothalamic lesions. 2, abnormal gland development, if the unilateral gland thickening, feminine development, gland thickness greater than 2 cm, consider abnormal gland development, you can consider surgery to remove the gland, but before surgery to fully evaluate to exclude other causes.
