Breast is mainly composed of glands, ducts, adipose tissue and fibrous tissue. The mammary gland consists of 15 ~ 20 gland lobes, each gland lobe is divided into several gland lobules, and each gland lobule consists of 10 ~ 100 acinus. The acinus is closely arranged around the small mammary duct, and its opening is connected with the small mammary duct. Many small mammary ducts converge into interlobular mammary ducts, and many interlobular mammary ducts converge into a whole glandular breast duct, also known as mammary duct. There are * * * 15 ~ 20 milk tubes, which are radially arranged around the nipple and converge in the areola, and the opening is located in the nipple, which is called the feeding hole. The ductus lactis narrows at the nipple and then expands into ampulla, which is called ductus lactis sinus and can store milk. The opening of mammary duct is stratified squamous epithelial cells, and the stenosis is transitional epithelium. The ducts at all levels below ampulla are double-layer columnar epithelium or single-layer columnar epithelium, and the terminal ducts are cubic epithelium near acinus, which is lined with cubic epithelium. The adipose tissue in the breast is wrapped around the breast to form a hemispherical whole. This layer of adipose tissue is called the adipose capsule. Due to age, fertility and other reasons, the thickness of fat sac may vary greatly among individuals. The amount of adipose tissue is one of the important factors that determine breast size.

If this round thing suddenly appears before, be alert to whether it is a lump caused by breast disease. Usually possible reasons are:

cystic masses

If you massage the lump with your fingers, you will feel very smooth. This type of lump will cause great pain, but in some cases, it will not cause pain. Disorder of hormone secretion regulating menstruation may lead to cystic masses. Women over 50 years old generally don't grow this kind of lump, and this kind of lump is not cancer. Through professional aspiration, pain and lump can be eliminated.

2. Sebum cyst

It's caused by blocked ducts in hair follicles. It feels like a cystic mass. Hormone stimulation or trauma can make the situation worse. If this lump does not cause other complications, then no treatment is needed. If you want to treat it, you just need to open a small hole in the protrusion and pull the blockage away.

3. Abscess

Abscess is caused by breast infection. This lump will be painful, and the skin on the surface of the breast will be red and hot. You may also have a fever all over. It can be cured by taking antibiotics or surgically removing infected tissue.

4. Fat lumps

This situation is just that the fat of the breast is changing, thus becoming a round lump. This lump will feel hard. The epidermis may turn red. Usually this lump will heal without treatment.

5. Breast cancer. Usually, there is an irregular lump in the breast. It will stick to the skin or deep tissues. Therefore, this lump can't be pushed with your fingers. However, breast cancer lumps do not cause pain. You can use a home breast examination instrument, such as the breast angel breast red light detector, to check the lump. If there are black spots and shadow areas, you should go to the hospital for diagnosis.

6. Adenoma

Adenoma is not cancer, but the normal growth of fat in glandular tissue in breast. Many times, African women around the age of 20 are more likely to have this situation. When you touch it with your fingers, you can feel that the lump is round and hard, and you can even move left and right.

7. Intraductal papilloma

This tumor is a tumor growth in the mammary duct. They usually grow under the nipple and even cause nipple bleeding. Women approaching menopause may have this condition in one breast. Young women may have this condition in both breasts.

Of course, your condition is likely to touch normal breast tissue, so don't worry, don't worry, just check it.
