[Concern] I'm worried about gynecomastia.

I am wondering if it is gynecomastia.

It's not fat in the chest, just the areola protruding like this.

The size of the areola is only about the size of a 500 won coin.

I had a lump in my chest when I was in elementary school, and I suspect gynecomastia.

Which hospital should I visit for gynecomastia examination or surgery?
