It's probably been asked before, but what size on average should the mass under the nipple be, and should it be hard or squidgy.

I have quite a firm (sensitive) solid mass under both nipples, the left side is biggest, and about the circumference of a golf ball, maybe sightly larger. Is this normal.

I try to research this on Google, but everything I read is scary, and talks about cancer and ultra sounds, they talk about seeing a GP with any signs of Gyneacomastia. Has anyone else experienced this?
