intraductal papilloma
Introduction
Introduction to intraductal papilloma The disease is also associated with localized papillary growth caused by over-stimulation of estrogen, which can be divided into single (intraductal papilloma) and multiple (intraductal papilloma). Can be seen in adult women of any age, but the most common incidence of 40 to 50 years old, males are rare. The rate of cancer in a single person is about 6%. Intraductal papilloma is often multiple, occurring in the small or small ducts of the mammary gland, can involve multiple ducts of multiple breast lobules, its biological characteristics tend to be cancerous, the cancer rate is as high as 30% ~ 40% can be considered as precancerous lesions. The cause has not been determined, but more scholars believe that the disease is also associated with localized papillary growth caused by excessive stimulation of estrogen. Intraductal papilloma is often multiple, occurring in the small or small ducts of the mammary gland, can involve multiple ducts of multiple breast lobules, its biological characteristics tend to be cancerous, the cancer rate is as high as 30% ~ 40% can be considered as precancerous lesions. basic knowledge The proportion of illness: 0.005% Susceptible population: The most common occurrence is 40 to 50 years old, and male is rare. Mode of infection: non-infectious Complications: breast ductal tumor

Prevention
Intraductal papilloma prevention
Women of childbearing age usually have to self-examine their breasts:
Starting from the sitting position, any nipple inversion, skin sag, and structural shape are all clues to deep breast cancer. If the patient clapped his hands on the head to contract the chest muscles, the above signs will appear. When the woman is in the sitting position, it is easy to check the collar bone. , under the axillary lymph nodes, and finally need to sit and palpate, use the fingers close together to touch the area under the nipple.
Take the supine position for palpation in a wider area, the pillow on the same side of the breast, the hand on the same side lifts the head, so that the breast spreads evenly on the chest wall, so that the finger can easily reach the deep breast cancer, apply the index finger, middle finger, ring finger The palm of the hand, rather than the fingertips, is palpated. The way of palpation should be in the form of a circle, which is rotated laterally from the nipple. It is especially important to check the breast that extends to the underarm.
Breast examination should first observe the development of the mammary gland, whether the breasts on both sides are symmetrical, whether the size is similar, whether the nipples on both sides are at the same level, whether the nipples have retracted depressions; whether the nipples, areola are erosive, how the skin color of the breasts is, whether or not there is Edema and orange peel-like changes, whether there is inflammatory and other inflammatory manifestations, whether the superficial veins in the breast area are angry.
Complication
Intraductal papilloma complications Complications Breast ductal tumor
Intraductal papilloma is a benign tumor, but there is also the possibility of canceration. Multiple intraductal papilloma has more chances of malignant transformation. It is a precancerous lesion and should be followed up.
Symptom
Intraductal papilloma symptoms Common symptoms Lactation disorders Breast lumps Breast tingling nipple discharge
For example, under the areola and its margins, a small lump or nodule, bloody or serous fluid overflow during light pressure, can be diagnosed, such as failure to sputum and mass, using finger pressure method to the tip of the index finger around the nipple Pressing the areola area clockwise, it can be seen that there is a discharge in the unilateral single breast duct of the corresponding part of the nipple, and a diagnosis can be made. In some cases, although nodules can be seen, there is no discharge when pressed.
Most patients have no discomfort, only intermittent, autonomous nipple discharge, the liquid is bloody or serous, but if the larger tumor block the lactiferous duct, it can produce pain and lumps. Once the blood is discharged, the mass also follows. It becomes smaller, the pain is relieved, and disappears. This phenomenon can be repeated. Most patients are treated for nipple discharge. The discharge is bloody, serous or bloody and serous, and a few patients find a mass near the nipple.
In the intraductal papilloma, the tumor is small, generally can not be paralyzed, and sometimes in the areola area and small nodules, bloody or coffee-like liquid can be spilled from the nipple when lightly pressed.
In the intraductal papilloma, the main manifestations are that the mammary gland can be smeared and the border can not be clarified, the uneven texture of the mass, or no lumps and less nipple discharge.
Examine
Examination of intraductal papilloma
The laboratory tests required for this disease mainly include X-ray examination and effusion cytology:
X-ray examination: Mammography can often show the location and size of the tumor. It has been reported that the diagnostic coincidence rate can reach 93.7%.
Effusion cytology: nipple effusion smear, visible red blood cells and epithelial cells, even cancer cells can be found.
Diagnosis
Diagnosis and diagnosis of intraductal papilloma
Intraductal papillary carcinoma: usually under the areola, the mass is often larger than 1cm. When the pressure is pressed, there is a bloody discharge in the corresponding duct of the breast. The surface of the tumor is not smooth, often adheres to the skin, is not easy to push, no tenderness, and the lymph nodes can be swollen. Large or dilated, the milk duct can be dilated and destroyed, and pathological examination can confirm the diagnosis.
Mammary duct dilatation: nipple discharge can overflow from multiple catheter mouths, and the traits are more common in transparent or yellow. In some cases, it can be seen under the areola and multiple small nodules. It is consistent with the direction of the mammary duct, the boundary is unclear, and the skin Often there are adhesions, accompanied by tenderness, axillary lymph nodes may be swollen, but soft, tender, breast ductal angiography can be seen thickening of the catheter, but the catheter has no hyperplasia or destruction, no lesions in the tube, smear often no special Find.
