Hi Nessa, i might be wrong hun but i thought breasts where made up of fat and actual breast tissue which is the tissue and ducts connected to the mamaryglands or even a bunch of mamaryglands aswell as milk ducts connected together. The breast tissue is what gives breasts there firmness and the denser the tissue the firmer your breasts will be. When you have a mammogram you can see the tissue and the fat as they show up as different colours. Thats why its possible for some very slim women to have large breasts even though there fat content is fairly low they have alot of tissue. Im no expert though this is just what i have been told lol.
