A newborn baby has nipples, areolas, and the beginnings of breast tissue, but most of breast development occurs in two different periods of time in a woman's life: first in pubertythen during pregnancy. Breast development is a vital part of puberty in the human female. Interestingly, humans are the only mammals whose breasts develop before they are needed to serve their biological purpose—breastfeeding.
There is evidence of early puberty leading to increased risk of obesity, type 2 diabetes, heart disease and cancer — particularly breast cancer. Until now, unfortunately, scientists have poorly understood the processes that make some girls develop younger than others. But new findings from our research at the University of Glasgow solve a large part of the mystery and could have important health implications as a result.
Breasts come in different shapes and sizes, but there's one thing they all have in common: They are unique to humans. More than 5, mammalian species inhabit this planet. Yet Homo sapiens are the only life forms with permanent breasts.
Gigantomastia is a rare condition that causes excessive growth of the female breasts. Only a couple hundred cases have been reported in the medical literature. The exact cause of gigantomastia isn't known. The condition can occur randomly, but it has also been seen to occur during puberty, pregnancy, or after taking certain medications.
Some girls can't wait for them to come and look forward to their arrival as they would their birthday, first kiss, or a soccer championship. Other girls dread them as much as eating a big plate of Brussels sprouts or changing the kitty litter. But most girls have mixed feelings and are not quite sure why they have them and what to do about them.
Why do straight men devote so much headspace to those big, bulbous bags of fat drooping from women's chests? Scientists have never satisfactorily explained men's curious breast fixation, but theorists are gonna theorize. Mammary glands are a defining feature of mammals, but humans seem unique in granting mammaries a large sexual role.
Far from offensive, the query was appropriate and astute. My classmates and I nodded approval, and the professor added it to a growing list on the board. We were brainstorming features that distinguish our species, Homo sapiensfrom other primates.
Breast hypertrophy is a rare medical condition of the breast connective tissues in which the breasts become excessively large. The condition is often divided based on the severity into two types, macromastia and gigantomastia. Hypertrophy of the breast tissues may be caused by increased histologic sensitivity to certain hormones such as female sex hormonesprolactinand growth factors. It was first scientifically described in
I'm an animal science student and during our mammogenesis lecture a professor brought up the obvious, but seemingly overlooked notion of the size of the female human breast. Other species do have obvious teats and great apes have breasts, but humans are at the extreme end — obviously not all — but it does make one wonder on a selection and genetic level, why? The full, plump bosom seen in the human ape is an anomaly.

Her work can be found on SafeBee, Fisher-Price. Large breasts are both a blessing and a curse. They're either regaled or minimized and hidden, depending on the culture in which you are raised.
