10 facts you surely did not know about breasts | The NY Journal

The breasts are an organ that occupy a central place in the anatomy of women, but also on a social and cultural level.

The breast is made up of soft tissue that contains the mammary gland, which is a complex system made up of fat cells and other ducts that produce milk, which is essential for any human being in their first months of life.

But breasts hold many more “wonders” than just the issue of breastfeeding. Dr. Constance M. Chen, who is a plastic surgeon, breast specialist, shares some curious, fascinating and important facts that you should know about them.

10 curiosities about breasts

1) Its size is hereditary

Genetics play a role in determining the size of the breasts. We inherit half of our genes from each parent, so yours may not look like those of your mother, grandmother, or sister.

Also, the weight will be decisive since they are made up of fatty tissue, so that as you gain or lose pounds, their size will change.

2) Humans are the only mammals with permanent breasts

All mammals have breasts and produce milk for their young, but we are the only ones who develop breasts at puberty and maintain them throughout our lives.

3) Animals can also develop breast cancer

It is more common in dogs, and some breeds, than cats, but it tends to be more aggressive in felines. Spaying bitches before their first heat dramatically reduces the risk of developing a malignant mammary tumor.

4) The left breast is slightly larger than the right

Very few women have perfectly symmetrical breasts. Size differences of up to 20% are normal. No one knows why the left breast is usually the largest.

5) There has been an increase in size in recent years

The average bra size was 34B 20 years ago. Today is 34DD. Part of the change is due to companies inflating sizes on their labels, but increasing obesity, the number of women taking birth control pills and exposure to environmental pollution are contributing factors.

6) There are records about breast cancer from 1600 BC.

The ancient Egyptians knew about this disease. The papyrus writings describe tumors consistent with modern descriptions of the disease. During the centuries that followed, many causes were suggested, from imbalances of bodily fluids to compression of tight clothing, and treatments ranged from cauterization to opium and arsenic.

7) No exercise will make them grow

The breasts are made of tissue, not muscle. They can change in size with hormonal and weight changes. But even exercising the underlying chest muscles will not increase the size of your breasts.

8) Breastfeeding does not cause them to fall

Sagging breasts are a natural consequence of aging, as the skin loses elasticity and dense breast tissue is replaced by fat, which is more prone to sagging. Smoking and multiple pregnancies are factors that can contribute to this. Only corrective surgery can lift sagging breasts.

9) Large breasts do not produce more milk

Milk production does not depend on the size of the breasts. Large breasts are usually large because they contain more fat cells, not more milk-producing cells.

10) Implants don’t last a lifetime

Breast augmentation is the most frequently performed cosmetic surgery in the US, but women who receive implants in their 20s should not expect to have them thirty years later, as most have a 10-year warranty.
