Breast cyst

Introduction to the accumulation of cysts Because of the poor discharge of a glandular lobe, the cyst formed in the mammary gland is called cystofgalactostasia, also known as milk retention cyst, or milk stagnation. It is a benign disease in pregnant and lactating women. It is characterized by obvious lumps and is easily misdiagnosed as breast fibroadenomas or breast malignant tumors. basic knowledge Sickness ratio: 0.05%-0.08% Susceptible people: seen in women Mode of infection: non-infectious Complications: breast cancer breast pain

Causes of lactation cysts

Breast disease (45%):

If you have breast hyperplasia during breastfeeding, inflammation or tumor compression caused a blockage of the glandular or lobular duct of the breast, so that the accumulation of milk in the catheter can not be ruled out, but also due to poor breastfeeding habits (untimed breastfeeding, milk is not empty), The milk stagnates in the catheter, causing the catheter to expand to form a cyst.

Bacterial infection (30%):

Since the milk retained in the capsule contains a large amount of sugar, fat and protein, it is the best medium for bacteria. If bacteria invade, it may cause secondary infection, which may lead to acute mastitis or breast abscess. If there is no bacterial invasion, the cyst can persist in the mammary gland for a long time.

Cumulative cyst prevention

1. Develop regular breastfeeding habits to avoid milk retention in the mammary gland because the milk is not empty.

2, pay attention to breastfeeding hygienic and posture, to avoid milk retention caused by poor milk drainage, combined infection.

3, pay attention to postpartum diet, avoid eating spicy food, eat more light, high protein content of food.

Lactocyst cyst complications Complications Breast breast pain

Women with high breast density and firm texture are prone to breast cancer. In addition, adolescent breast abnormal hypertrophy, excessive breast care when underage, or in order to maintain breast fullness and beauty in the breast filled with some inappropriate substances for breast reconstruction, etc., is also one of the causes of breast cancer. Women with fibrocysts have a 2 to 4 times higher chance of getting breast cancer than normal people, and can have breast pain.

Cucumber cyst symptoms Common symptoms Painful axillary pain

The onset time is often during lactation or pregnancy, especially after weaning. There may be acute or chronic inflammation, trauma or surgical history, and more cases have occurred in breast inflammation, trauma and surgery.

Pain

Most patients have mild pain, such as redness and tenderness in the skin with secondary infection. The ipsilateral axillary lymph nodes often increase and are tender.

2. Lump

The intratumoral mass is round, the surface is smooth and movable, the capsule is sexy, the border is clear and there is no tenderness, and the diameter is more than 2 to 5 cm. Stop shrinking after breastfeeding, or shrink after massage. The big lumps are sexy and seem to be elastic. When the contents of the capsule become thick, the elasticity disappears, the hardness increases and becomes firmer, and it is easily misdiagnosed as breast cancer.

Examination of lactation cysts

1. Swelling needle cytology

(1) Specific operation: A large amount of milk-like liquid can be extracted in the early stage. The mass can often shrink after the puncture of the milk, but it cannot completely disappear. If it is not easy to suck out the contents of the capsule, it may be because the moisture content of the capsule is absorbed and thickened. At this time, the needle can be changed by suction, and the cheese sample can often be obtained to determine the diagnosis.

(2) Examination results: The smears of the extracts were examined to show fat droplets of different sizes, a large number of swollen denatured foam cells, ductal epithelial cells, and a small number of dispersed glandular epithelial cells. If you see degenerated neutrophils, it is often suggested that secondary infection may occur.

2. Molybdenum target X-ray film

Most of the cysts are round, elliptical translucent areas, mostly located outside the areola area, close to the edge of the breast.

3.B-ultrasound

In the reflected wave of the mammary gland, the part corresponding to the cyst has a typical liquid boundary or liquid dark area with clear boundary, and there is obvious reflection of the ingress and egress wall before and after the liquid level. Through the longitudinal and transverse sonograms of the cyst center, the three diameters of the cyst can be determined to understand the size and extent of the cyst. The distance between the reflections of the two walls represents the anteroposterior diameter of the cyst.

4. Histopathological examination.

Diagnosis and identification of breast cysts

Diagnostic criteria

1. The onset time is often during lactation or pregnancy, especially after weaning.

2. There may be acute and chronic inflammation, trauma or surgery history, the incidence of the site has been more than breast inflammation, trauma and surgery.

3. The intra-milk mass is round, the surface is smooth and movable, the capsule is sexy, the border is clear and there is no tenderness, and the diameter is more than 2~5cm.

4. Puncture can extract milk or cheese samples.

5. X-rays appear as well-defined cyst shadows.

Differential diagnosis

1. Breast fibroadenoma: The age of onset of breast fibroadenoma is lighter than that of accumulating cysts, often in puberty or premarital period. The latter often occurs after breastfeeding. The hardness of breast fibroadenoma is more than that of breast cysts. Large degree, often easy to slip off when palpation, the latter mass often has cystic, elastic sense, when the diagnosis of puncture, such as pumping out milk-like liquid, can exclude breast fibroadenomas.

2. Breast cystic hyperplasia: cystic hyperplasia of the breast also often forms cysts, but its cysts are often multiple, in addition to a larger cyst, there are often many small cysts such as mung bean in the milk, and often Not limited to one side of the breast, although the cyst and the lactation cyst have similarities in morphology, mobility and sac, but the cyst content is often serous, rarely milky, cystic hyperplasia of the breast With the menstrual cycle changes, there is more obvious breast pain or tingling, but there is no such symptom in the breast cyst.

3. Breast cancer: The early stage of breast cancer is only a mass in the breast, but there is no peripheral soft tissue infiltration and axillary lymph node metastasis, sometimes it is not easy to distinguish from the breast cyst. The breast cancer mass is irregular in shape, the surface is uneven, and the boundary is uneven. Unclear, hard texture; while the cysts are clear, the surface is smooth, and there is moving elasticity and sac sexy. The breast cancer lumps on X-ray films are often burr-like, the edges are not neat, and the density of calcium spots is often concentrated in the central area. The accumulation of cysts in the breast is relatively neat, and the density of the calcium spots is higher than that of the center. When the needle cytology is examined, the cancer cells can often be found in the breast cancer, while the cysts often take out the milky liquid. Can be qualitative.

4. Breast tuberculous abscess: The cold abscess of breast tuberculosis has a history of chest wall or breast tuberculosis, and there may be infiltration and adhesion around the abscess. The puncture examination is pus instead of milk, and the pus smear can be used for acid-fast staining. To the acid-fast bacilli is the evidence of the difference.
