I am a young man, eighteen years old. Four years ago, I developed chest fat (“male breasts”). That was accompanied by some pain; after a while, the pain disappeared, praise be to Allah, but the “male breasts” remained. They can clearly be seen under my clothes. I asked a specialist doctor about that, and he told me that they can easily be removed, by means of a cosmetic surgical procedure. Is it permissible for me to have such surgery? Please note that these “breasts” cause me a great deal of embarrassment in front of other people.
