Is this due to masturbation?

I don't think masterbation is causing a fatty breast. Masterbation doesn't have any effects...is it just in one of you breasts or in both? Does it hurt? Or feel sensitive? Not to alarm or worry you...and im not sure if your male or female, but if you are a male, like i said not to scare you but men can get breast cancer as well as women. You should get it checked out by a doctor. Or maybe your glands are just swollen.
