What do all breasts have in common?

This seems like a good place to start, with a foundation of what we are talking about.  While talking with my family, friends and acquaintances about breasts, as I was developing the idea of Breast Love, most of them were stumped by the question “What are breasts made of?” Seems fair really, that they would be, since we don’t really talk about them, not really. We talk about our right to show them, feed with them, and to be treated equally even if we have them, but we don’t talk about them very often. So let’s chat…


Breasts are largely comprised of fat which is usually why they change size with weight gain or loss. The lymphatic system winds through them with a cluster of nodes above them and to the side. The lymphatic system is the most significant component of our immune system. There is also connective or fibrous tissue which can impact the density of the breasts. It can be more difficult to identify challenges with the breasts when tissue is dense. Density is different from woman to woman but tends to decrease with age. Density tends to be greater with young women, while women over 50 tend to see the density decrease. The connective ligaments also tend to sift with age, which is partly why breast shape also changes. The breast also contains glands or lobules, that create milk, and ducts that carry the milk to the nipple. Externally you will see a nipple that may stick out, or could be inverted. The skin around the nipple is the areola.

Breasts develop in girls when the estrogen levels hit a point that sets off the chain reaction. Humans are the only mammals that have fully developed breasts unrelated to childbearing. Other mammals develop breasts only during pregnancy. What do you think life would be life for humans if we didn’t develop breasts until we needed them for feeding children?
