Hello! Today we are going to talk about a small, but very important part of our body. That is the nipples. You may not have thought much about this, but nipples are not just anything. Let's take a closer look at this.
What is a nipple?
Simply put, the nipple is the small raised area right in the middle of your breast. Usually, everyone has two nipples, one on each side of their chest. These can often be slightly protruding. But some people's nipples can be flat or inverted. You may have noticed that there is a dark, round area of skin around the nipple. That's what we call the 'areola'. So doctors call this nipple and the areola around it together as the `nipple-areolar complex' (NAC) .
What is the function of the nipple?
Imagine how big this little nipple can become! The most important thing is breastfeeding. When your baby is born, when he takes the nipple and areola in his mouth and sucks, milk comes out of the little holes in the nipple. That's what nourishes the baby.
Also, the nipples are a place that is associated with sexual pleasure for both men and women. They are very sensitive to touch because they have a large number of sensory nerves.
How big are nipples usually?
This can vary slightly from person to person. But on average, a nipple is about 10 to 12 millimeters wide. It may also protrude about 9 to 10 millimeters from the surrounding skin. But remember, this is just an average value. It is normal for your nipples to be smaller or larger than this. Don't worry about it.
What is the anatomy of the nipple?
The nipple is made up of smooth muscle fibers, connective tissue, and tubes called `milk ducts` that carry milk. In each nipple, there are about nine small holes, or `orifices`, through which milk comes out. In addition, there are hundreds of nerves . These nerves are what give us sensation in the nipples. These muscle fibers cause the nipples to contract and protrude in response to cold or stimulation.
What are the different types of nipples that can be seen?
We can classify nipples by their appearance and by the number you have.
Types of nipples by appearance
Your nipples may look like this:
- Protruding: These are the most common type. The nipples protrude from the areola, looking like a small cylinder.
- Flat: These nipples are neither protruding nor inward. They are at the same level as the areola.
- Inverted: These look like the areola has been turned inward. The nipple is turned inward.
Now, flat or inverted nipples are a common, harmless condition that is usually present at birth. Sometimes, mothers with these nipples may find it difficult to breastfeed their babies, but there are ways to deal with it. However, if you notice that your nipples have suddenly become flat or inverted, you should definitely see a doctor. This change may not be harmful, but it can sometimes be a sign of cancer or another condition that needs treatment, so it is important to be aware of it.
By the number of nipples
Most people have two nipples – one on each breast. But here are some things that can happen:
- Having three or more nipples (`supernumerary nipples`): Most people with this condition have only one extra nipple (a third nipple). However, some people can have up to eight. These extra nipples can usually be located anywhere along the breast line, from the armpit to the groin.
- Absence of nipples (athelia): Some people are born without nipples. This is due to changes in fetal development. Sometimes it can be associated with a genetic condition such as Poland syndrome (a condition in which the chest muscles do not develop properly).
What diseases and conditions can affect the nipples?
Breast cancer can affect your entire breast as well as your nipples. Here are some types of breast cancer that start in the nipples:
- Ductal carcinoma in situ (DCIS): This cancer starts in your milk ducts. But it usually doesn't spread beyond them. It often doesn't have any symptoms. Doctors find it with imaging tests , such as a mammogram.
- Invasive ductal carcinoma (IDC): This also starts in the milk ducts and spreads to the surrounding tissue. It can appear as a dimple, wrinkled, ridged, or swollen lump in the skin of the breast or nipple. You may feel a lump in the breast, and the size or shape of the breast may change.
- Paget's disease of the breast: This cancer develops in the skin of the nipple. It causes symptoms such as itching, burning, discharge, and oozing of the nipple and/or areola. Sometimes this may look like eczema, but it can be cancer and should be checked out immediately.
Another condition that can affect the nipples, in addition to cancer, is nipple eczema . This is an itchy, red, scaly rash that appears on the nipple and areola (and sometimes other parts of the body). It's not always easy to tell the difference between eczema and breast cancer. That's why it's so important to see a doctor right away if you notice any changes in your breasts.
How do I check the health of my nipples?
Doctors usually use mammograms to check the health of your entire breast, including the nipples. They also use tests called breast ultrasound and breast MRI in some special cases.
It is usually recommended that you have a mammogram every year after the age of 40. However, if you are at high risk of developing breast cancer, for example, if someone in your family has had it, your doctor may recommend that you start getting these tests earlier. Even if you are a man, if you have certain risk factors (e.g. family history, genetic predisposition), your doctor may recommend these tests. Don't forget that, although rare, men can also get breast cancer.
How do I take care of my nipples?
There are several ways you can take care of your nipples:
- See a doctor regularly for breast exams and recommended tests, such as mammograms. Your doctor will tell you how often you should have these tests.
- Do a breast self-exam every month. This will give you a good idea of how your breasts normally look and feel. If you notice any changes or feel a lump, tell your doctor right away.
Being aware of your body is the best way to stay healthy!
When should I see a doctor?
If you have any of the symptoms below, please see a doctor immediately:
- Nipple pain or tightness that lasts for several days or for which no cause can be found.
- Changes in the color or texture of the nipple or surrounding skin (e.g., redness, dimpling, orange peel appearance).
- Nipple fissures.
- A lesion anywhere on the nipple or breast.
- If you are not breastfeeding, you may have a liquid-like discharge from your nipples (`nipple discharge`) , especially if it is bloody or only comes from one nipple.
- The nipple suddenly becomes flat or inverted, something that wasn't there before.
- If you are breastfeeding, you may notice a small white, clear, or yellow spot (`milk bleb`) on your nipple. This could be due to a blocked milk duct.
Seeking medical advice as soon as you notice a change in your nipples can help you identify a problem early and begin treatment. It's better to see a doctor and know that it's not serious than to wait and think, 'This might not be a big deal,' right? That quick decision could even save your life.
If you have a nipple piercing, ask your doctor about how to care for it. This is especially important if you are pregnant or breastfeeding, as there is a risk of infection.
The most important message to take home
So, even though nipples are small, we shouldn't ignore them. If you notice any changes in the skin on your nipple or the areola around it, it's definitely a warning sign that you should tell your doctor. Not all changes are serious. However, if they are serious, early detection and treatment can make a big difference. Talk to your doctor about what you can do to protect the health of your nipples and breasts. To stay healthy, we need to take care of our bodies, right?
