Breast Anatomy: Let's learn exactly about this amazing part of your body

Have you ever really thought about your breasts? They are not just a part of the body. Especially for a woman, breasts are a wonderful organ that says a lot about motherhood, femininity, and health. So today, let's find out exactly how these breasts are formed, what's inside them, and what we need to do to keep them healthy.

Simply put, what are breasts?

Breasts are something that both men and women are born with. However, the function of the breasts of both men and women is different.

• For a woman , the main function of the breasts is to provide milk to a child. They are also a sensitive area that brings sexual pleasure.
• For men , breasts don't perform any special physiological function, but they can be a sensitive area for them too.

What we see on the outside of a breast is the nipple and the dark skin around it, called the areola . Normally, everyone has two breasts.

What are the three main layers of a female breast?

A woman's breast is made up of three main types of tissue. These breasts are connected to the ribs of our chest by muscles. Let's take a look at what those three types of tissue are.

1. Glandular Tissue: Also called `(Lobules)`. Simply put, these are the "milk-producing factories". The milk needed to feed a baby is produced from these tissues.

2. Connective or Fibrous Tissue: This is like the 'framework' of the breast. It is this connective tissue that helps hold the glandular tissue mentioned above and the fatty tissue mentioned below together and in place.

3. Fatty Tissue: This is the most abundant tissue in the breast. It fills the spaces between the glandular and connective tissues and gives the breast its shape and size. The size of your breasts is determined by the amount of this fatty tissue.

Male breasts also contain a small amount of fatty tissue and glandular tissue with underdeveloped milk ducts. Sometimes, male breasts can become enlarged due to hormonal imbalances. We call this condition `(Gynecomastia)`.

Let's take a closer look at the internal structure of a breast.

The table below will help you understand the different parts of a breast and their functions.

How do hormones affect breast function?

Female hormones are essential for breast growth and function. There are four main types of hormones involved.

• Estrogen: This hormone causes the milk ducts to lengthen and branch out, creating pathways to carry more milk.
• Prolactin: This is what prepares the glands to produce milk.
• Progesterone: This increases the number and size of lobules (milk-producing glands) for milk production. It also enlarges blood vessels and breast cells after ovulation.
• Oxytocin: It's not enough to just produce milk, it has to come out in a way that the baby can drink. This hormone helps the milk produced in this way to be released.

What are the common conditions that affect the breasts?

When we talk about breast health, the first thing that comes to mind is breast cancer. That is the main risk. But apart from that, there are a number of other medical conditions that can affect the breasts.

Here are some common situations:

• Benign breast disease
• Breast cysts
• Breast lumps
• Breast pain (Mastalgia)
• Breast rash
• Fibrocystic breast changes
• Mammary duct ectasia
• Breast Infection (Mastitis)
• Nipple discharge

What are 'Dense Breasts'?

If you have a mammogram, the report may say, "You have dense breasts." Don't be alarmed when you hear this.

Simply put, dense breasts are breasts that have more glandular and fibrous tissue than fatty tissue. This cannot be determined by the size of the breast or how it feels. It can only be determined with a mammogram.

What is the significance? On a mammogram, both dense tissue and cancerous tumors appear white. This can make it harder to detect cancer in someone with dense breasts. Also, dense breasts have a slightly increased risk of developing breast cancer. If your report says so, talk to your doctor about it and your risk.

How can I keep my breasts healthy?

Since breast cancer is a major risk, ask your doctor when and how often you should have a mammogram, based on your age and family history.

Also, breast self-exam is very important. It's not just about checking for cancer. It's about getting to know your breasts better. Then, if there's any unusual changes (like a lump or skin change), you'll be able to recognize them quickly.

What are the symptoms that require immediate medical attention?

If you notice any of the following changes in your breasts, don't ignore it and definitely see your doctor .

• Finding a new lump in the breast or armpit.
• Abnormal discharge (such as blood, yellow liquid) from the nipple (especially in one breast).
• Unusual pain in the breast.
• A change in the shape or appearance of the breast or nipple (skin sinking in, orange peel-like appearance, redness, swelling).
• Inverted nipple is a nipple that was previously normal and suddenly turns inward .
• A non-healing wound or eczema-like condition on the skin of the breast.

Additionally, if anyone in your immediate family (such as your mother or sister) has had breast cancer or ovarian cancer before the age of 50, tell your doctor about it as well. Then, if necessary, you can be referred for testing sooner.
