Discoveries : Do You Know?? Check Out Some Facts About The Female Mammary Gland " The Bre*st" You Never Knew... Continue Reading 👇
One of the things noticed on a woman is her breasts mainly because of its protruding nature. Women’s breasts are made of specialized tissue that produces milk (glandular tissue) as well as fatty tissue.
Breasts is a topic people don’t easily get tired of; boys don’t have it but like it when they see it on a girl. Girls with small-sized bubs, sometimes want it bigger. The truth is that beauty doesn’t come in just one bra size. There are all sorts of female shapes and sizes in the world, and all are beautiful.
Check out six facts about boobies you probably didn’t know
1. Men have breasts too
This not a joke. Asides overweight men who retain fat in their chest area resulting in bubs, some men have breasts just like women. However, it is a rare condition known as gynecomastia, where the mammary glands are abnormally overgrown. Also all fetus is female at first which is why men have nipples.
2.There’s a woman in record history that has the largest bubs in the world
Annie Hawkins is the woman known to have the largest pair of bubs in the world. According to the Guinness book of record, her breasts is rested on her 70 inch chest. Annie’s surfers from a condition known as gigantaomastia, which is slow but steady growth of bre@st and fat tissue.
3. Uneven breasts is normal
Research says, having uneven breasts is completely normal. A lot of women have one bre@st slightly bigger or smaller than the other. It is not a problem and it’s quite common.
4. There are 5 types of nipples.
Not all nipples are the same. They vary in shape and size and none is dependent on the size of the breasts. The popular types of nipples are: Normal, flat, puffy, short/long nipple, inverted nipple ( there are different kinds of inverted nipple).
5. Breasts can weigh about as much as three bricks
Heavy load. According to research, breasts can weigh as much as nine kilograms which is why bras are specifically designed to support breasts within the range of 0.23 kilograms to 9 kilograms. Just imagine carrying three bricks around all day every day and then sleeping with them on your chest.
6. There is a degree called “bra studies” in china
You can get a degree studying bras in china. The degree title is “bra studies” and just like every university degree, upon graduation there’s a certificate awarded in honour of your “education.” Imagine interviewing someone that has a degree in bra studies. Wonder which companies employ them

Women's Breasts 'eat' themselves after they
Scientists have identified the molecular switch that causeswomen's breasts to stop producing milk when they stop breastfeeding. Oncelactation is complete, cells in the breasts devour dead cells that are leftover from the breastfeeding process.
Scientists had previously been baffled about how breastscould rapidly transform from milk-making machines back to their natural statein a matter of days.
It is hoped that the new research could provide vital insights into thedevelopment of breast cancer.
'Women's breasts comprise a network of ducts, covered by alayer of fatty tissue,' explains New Scientist.
'During pregnancy, hormonal signals cause epithelial cellslining the ducts to proliferate and form ball-like structures called alveoli,which is where milk is made when the baby is born.
'However, once women stop breastfeeding, these structuresself-destruct – a process that involves massive cellular suicide, and theremoval of the debris'.
While the body is known to remove dead cells through aprocess called phagocytosis, the scale of such a process would usuallycause significant swelling and pain.
This doesn't appear to happen when a woman finishesbreastfeeding, and scientists were not sure why until now.
Epithelial cells - those which line the the ducts in the breasts - effectively'eat' the dead cells that are left over after breastfeeding.
Researchers set out to investigate whether a protein calledRac1, which is known to be a vital element of milk production, is responsiblefor the post-breastfeeding transformation.
A study by researchers at Sheffield University deleted theRac1 gene from female mice and found that their first litter survived, but wereundersized.
It was suggested that this could be a result of lower fatand protein levels in the milk.
However, subsequent litters of the mice did not survive.
Without Rac1, the rodents' breasts were flooded with milk and dead cells,causing continuous swelling, which is thought to have inhibited the mice'sability to regenerate cell tissue and produce milk in later pregnancies.
The study shows for the first time that Rac1 is essentialfor clearing out dead cells and milk when lactation is over.
'Given this new role for Rac1 in the removal of excess ordead cells, thereby suppressing inflammation the current study also identifiesa potential role for Rac1 in breast cancer that is yet to be explored,' MatthewNaylor, a cancer specialist at the University of Sydney in Australia told NewScientist.
The study was published in the journal DevelopmentalCell.
