Facts to Know About Breasts

Here are 12 facts you should know about breasts.

1. You inherit your breast size

Sounds like a no-brainer, right? Well, there is an equal chance of inheriting your chest size from either of your parents. The chest size of the parent you inherit determines your breast size.

This means your breast size may vary significantly from your mother’s. She might be busty while you are not. Additionally, this is why two siblings can have different breast sizes.

2. Your breasts are not equal, and that’s perfectly normal

You have probably noticed that one breast is larger than the other. Do not fret; this is perfectly normal. In fact, the left breast is usually one-fifth larger than the right breast. (Are you bringing out the mirror for this one?)

3. Your breasts contain more than fat

Contrary to what some people may think, breasts contain more than just fat. Breasts contain a complex system of glands and ducts. That’s not all. There are muscles and fibrous tissues that separate your breasts from your ribs.

Your breasts will ultimately become mostly fat, but that’s after you cross a certain age.

4. The average bra size has increased.

About two decades ago, the average bra size was 34B. Now, it is 34DD! Find out more interesting facts about bras here.

5. Your boobs can gain weight too!

One important fact you should know is that gaining weight can make your breasts larger. If you lose weight, you might also notice a significant decrease in breast size. However, there are exceptions. Women with less fatty tissues in their breasts don’t experience this as much as others.

Other factors can increase your breast size: pregnancy, breastfeeding, menopause, birth control pills, and even sex! Furthermore, your breasts can become noticeably bigger during your menstrual cycle. But as you complete your period, your hormone levels drop, and your breasts return to their usual size.

6. All breasts will sag eventually

We can’t state this important fact enough: Sagging is natural and inevitable. Unless you have corrective surgery, your breasts will sag as you grow older. If you want to slow the process, you need to reduce or eliminate smoking.

You also have to watch the way you sleep. If you sleep on your stomach, you might want to change positions. According to reports, sleeping on the stomach can change the shape of your breasts over time.

7. Your breasts are mobile

If you are a physically active person, you should be able to relate to this important fact. As you run, you will notice that your boobs tend to move with you. According to a recent study, your breasts can move around as much as eight inches. The study showed that all breasts move up, down, and all around, regardless of size. This is why many sports experts recommend a supportive sports bra for sporting activities.

8. A third nipple isn’t so uncommon

About 6% of the population has more than two nipples with extra breast tissue. During menstruation, these “extra breasts” can become sensitive and even lactate! That is an important fact we wish everyone knew.

9. The first breast augmentation surgery took place almost a century ago!

It was in 1962, to be precise. It became the most popular form of plastic surgery in 2006 and had held on to that title ever since. According to a report by the American Society of Plastic Surgeons, almost 300,000 people got breast implants in 2013 alone! The average cost for the procedure was above $3,600.

10. Humans are the only primates with permanent breasts.

Humans develop breasts from a young age, even before the onset of puberty. The breasts continue growing well into maturity. Of course, they also get significantly larger during menstruation and pregnancy.

For other primates, breast growth only occurs when they are breastfeeding.

11. There are one, two, three… no… four types of nipples!

Yes! The four types are protruding, flat, puffy, and inverted. Guess what, they are all normal!

12. The average boob size is between one and two pounds.

While there are certainly exceptions, most breasts fall into the 1 to 2 pounds range. According to the Guinness Book of World Records, the largest natural breasts weigh almost 100 pounds! They also wear a size 521 bra!
