Which part of a woman's body is most likely to develop a tumor?

Breasts are one of the most interesting organs in the human body. It nurtures offspring, expresses sexiness, and brings wonderful sexual experiences. For thousands of years, people's obsession with breasts has never changed, but they know very little about the facts. With the continuous deepening of scientific research, the mysterious veil of breasts is slowly being lifted. The latest article on the Popular Health Network tells us these surprising but very interesting facts.

The older you get, the more breast fat you have

In your 20s, breasts are made up of fat, mammary glands, and collagen. As we age, mammary glands and collagen are gradually replaced by fat. Unfortunately, carrying a lot of fat doesn't make your breasts appear larger, but can actually make them sag more.

Breast size is uncertain

Breast size varies from person to person, and the same person's breast size can also vary greatly at different ages. The direction of the breasts is also very different. Some breasts are close together, while others are tilted to the sides. The average weight of a woman's breasts is 1.1 pounds (about 0.5 kilograms) and accounts for 4%-5% of the total body fat.

Human breasts are getting bigger. Due to factors such as nutrition and environment, women are getting fuller breasts at younger ages. The average breast size of American women is now 36D, compared to 34B 15 years ago.

On average, women have 2 to 15 dark hairs around their nipples. The darker the skin and hair, the darker the breast hair will be.

The breast is the most tumor-prone part of the human body.

Breast cancer is the most common cancer in women worldwide. Since the 1940s, the incidence of breast cancer has doubled and is still increasing.

The skin around the breasts is very thin. To keep the skin in this area moist, you can use cream to improve elasticity. At the same time, you must also prevent ultraviolet rays from damaging the skin, otherwise the breasts will easily develop wrinkles and the nipples will become dry.

Breasts also become erect

When sexually aroused, just like when a man's penis is erect, a woman's breasts will also enlarge. The average length of a woman's nipple when erect is 9.65 mm, which is equivalent to the thickness of 5 coins.

Your breasts can get sunburned even if you're wearing a swimsuit. Most swimsuit fabrics have a sun protection factor (SPF) of only 5-7. Therefore, before swimming, you should apply sunscreen with an SPF of at least 15 to your breasts.

Sleeping on your stomach is the most harmful to your breasts. If women sleep face down for a long time, their breast tissue will be squeezed too much, which will cause premature aging of the breasts, sagging skin, and deformation and expansion of the breasts. The best sleeping position to protect your breasts is to sleep on your side with a pillow under your breasts.

Monthly changes in breasts

Due to hormonal changes, the breasts are smoothest some time after menstruation ends (this is the best time to go to the hospital for a check-up). During the second trimester, hormone levels are high and nipples are most sensitive. During menstruation, when progesterone levels are high, your breasts may become tender, sore, or swollen. Both the breasts and areolas will grow larger during pregnancy.

Protect your breasts when exercising. Sports bras must maintain a certain degree of elasticity to reduce damage to the breasts caused by exercise and relieve breast pain. Push-ups and chest expansion exercises can help strengthen your pectoral muscles and make your breasts appear firmer.

Breast augmentation is the number one plastic surgery

There are more than 2 million women in the United States who have had breast augmentation surgery, and at least 4 million who have fake breasts. The average age for breast augmentation is 34, and 90% of people wait until after giving birth to have breast augmentation. This year marks the 50th anniversary of the first silicone breast implant surgery, which was performed in Houston, Texas, USA.

The breasts have an amazing ability to produce milk. Breast milk is rich in beneficial bacteria that can protect the newborn's intestines like a vaccine. Breast milk contains 1-600 species of bacteria. Most of these fungi are new to scientists. Breast milk contains endocannabinoids, which can make babies "addicted" to milk on the one hand, but prevent babies from drinking too much milk on the other.
