The extra breast tissue is usually in the torso, although this is not always the case.
Polymastia is when a person has more than two mammary glands, called accessory breasts, third nipple, or supernumerary breasts.
It is also sometimes called polymastia. The shape of the other mammary glands can vary, ranging from relatively underdeveloped breast tissue under the skin that may not even be visible externally to an additional fully functional breast or breasts.
This condition is related to but not identical to the more common condition called polythelia, in which a person has supernumerary nipples.
The supernumerary breast of a person with polymastia may or may not have a nipple. At the same time, polythelia more commonly refers to additional nipples that are not connected to the mammary gland tissue.
The medical condition of polymastia should not be confused with the sponge genus of the same name, which was called polymastia because the numerous structures protruding from its surface were thought to resemble nipples and have no bearing on the human medical condition.
Polymastia is also sometimes called hypermastia, although hypermastia generally refers to a condition in which the breasts grow to an abnormally large size.
Supernumerary third nipples may be more petite compared to normal nipples.
The condition is more prevalent in men than women. In most cases, the other nipples are smaller and less developed than normal nipples.
When a woman has given birth, and her milk “comes in,” her third nipple may be breastfed.
The supernumerary breasts that develop due to polymastia appear most often in a region called milk lines, structures present in all mammals of both sexes.
In humans, they are generally invisible and run down both sides of the torso from the armpits to the groin.
This structure is where an organism’s nipples and mammary glands begin to form. At the same time, it is still a developing embryo and is, therefore, the most common source of supernumerary breasts produced during embryo formation, although they can occur virtually anywhere. Place.
There are cases of people with supernumerary breasts in areas of the torso away from the milk lines, such as the back, but they can also appear on the extremities of a person or in places such as the buttocks, hips, or neck.
The extent to which the supernumerary sinus develops or is seen varies, both between different individuals and in the same individual under other conditions.
In some cases of polymastia, the supernumerary breast is fully developed, obvious, and can even breastfeed like a normal breast.
More commonly, it is not developed to that extent and may appear only as a lump under the skin, in which case it is often mistaken for a tumor.
In many cases, redundant breast tissue goes unnoticed until a physiological change that affects the breasts, such as the hormonal changes that women undergo during pregnancy and lactation, causes it to swell in size or become inflamed.
Polymastia is more common in women than men, but it can occur in both genders. Although many people with supernumerary breasts choose to have them surgically removed for appearance or self-esteem, it is not dangerous.
It is also possible for supernumerary breasts to develop breast cancer the same way as normal breasts.
Symptoms of polymastia
How is it recognized?
A third or supernumerary nipple is not always easily recognized. They are generally smaller and less developed than normal nipples. As a result, it is easy for a person to think that it could be something else, like a mole.
Some other nipples are so small that they cannot be recognized as a nipple, although others may look like one.
What does it look like?
It is common for a third or supernumerary nipple to appear on the front of the body between the area that begins in the armpit and passes through the nipples to the genitals. This is known as a person’s “milk line.”
However, third nipples can appear anywhere on the body, including the hands and feet (this is medically known as ectopic supernumerary nipples).
People can often dismiss their third nipple as a mole or birthmark. However, it is possible to tell the difference, as moles or birthmarks tend to be flat and are unlikely to have any bumps or ridges.
The types of polymathy
A category one nipple, or polymastia, may have an areola around it.
There are different types of supernumerary nipples, and these are classified based on specific characteristics such as shape and size, and tissue composition.
The different categories are as follows:
Category one (polymath)
In an additional category, one nipple will have an areola around the outside. An areola is a ring of smooth circular tissue. In this category, the underlying tissue is normal breast tissue; this indicates that an entire breast has also developed.
An additional category two nipples will not have an areola around it, although the presence of breast tissue underneath is still evident.
An additional category three nipple is where the area has breast tissue present, but no actual nipple has formed.
One category for the extra nipple is where breast tissue has formed underneath, but there is no nipple or areola.
Category five (pseudomamma)
An additional category five nipple has an areola around the nipple area, but instead of breast tissue underneath, there is fatty tissue in its place.
Category six (politelia)
An additional category six nipple is where the nipple appears on its own, and there is no areola or breast tissue underneath.
Some third nipples are so small that they look like a birthmark; many of them are also harmless. Learn more about the most common here.
Polymastia develops in the uterus. When an expectant mother is four weeks pregnant, the two milk lines of the developing embryo begin to thicken.
Milk lines are made of striated ectoderm tissue and will eventually become part of the baby’s skin.
Two strips of tissue that cross the thorax known as “mammary ridges” recede into the uterus and, in doing so, form two regular nipples. However, there are cases where they do not entirely reduce, resulting in the creation of additional nipples.
Diagnosis of polymastia
Many people can diagnose the condition independently, as the nipple will look similar to regular nipples and will appear in the milk line. In the case of women, women feel pain in the area with the hormonal changes of menstruation.
However, if a person is unsure, they can make an appointment with their doctor, who can tell if it is a third nipple or something else.
It is also essential to see a doctor if the extra nipple causes any discomfort (this may be due to breastfeeding or general pain). If the nipple becomes complex, additional lumps form, or a rash appears in the area, it is essential to seek medical attention as soon as possible.
If a person has a third or supernumerary nipple, it is advisable to make regular appointments with their doctor, who will check for abnormal or unusual growths related to activity in or around the nipple tissue.
They are rarely an underlying problem, so removing them is usually for cosmetic reasons and not related to health.
However, there are some cases where a third nipple may have an underlying problem that requires medical attention. A doctor may recommend that the nipple be surgically removed and prescribe other medications to treat the underlying cause.
Removal of a supernumerary nipple generally involves non-invasive outpatient surgery. The surgery is usually quick and causes minimal pain.
The doctor explains the diagnosis and treatment options to the patient.
In most cases, a third nipple will not cause any health risks. However, there are some complications to be aware of.
While rare, there are some cases where an extra nipple can signify a congenital breast defect or a malignant growth or tumor.
The Scaramanga gene can cause an extra nipple to form and cause the extra nipple to have breast cancer.
Certain additional types of nipples, such as polythelia (category six), have been linked to various kidney conditions, such as end-stage kidney disease, and may also be associated with kidney cell cancer.
