ductal tumor of the breast
Introduction
Introduction to breast ductal tumor A mammary duct tumor is a benign papilloma that occurs in the ductal epithelium of the breast. According to the number of breast duct tumor lesions and the location of the lesions, they can be divided into single type - large intraductal papilloma and multiple - medium and small intraductal papilloma. The disease has a high risk of malignant transformation and is called "precancerous lesions" and must be highly valued. The cause of the disease is unclear, but because the disease is common in the middle and old, it may be a degenerative change, and the invagination or deformity of the nipple. The squamous epithelium protrudes into the inner wall of the catheter, causing obstruction of keratinized scales, or fat. The secretions stimulate the wall of the catheter, causing inflammation, scar hyperplasia and secondary infection. Once the ductal tumor of the breast is formed, taking medicine can not be eliminated. Taking medicine can only play a role of conservative treatment, and control the development of the disease. The mammary duct tumor should be cured or surgically removed. It is recommended to have surgical resection because the papilloma in the duct is still There is a possibility of malignant transformation. basic knowledge The proportion of illness: 0.001% Susceptible people: common in middle and old women Mode of infection: non-infectious Complications: breast cancer
Cause
Causes of breast ductal tumor
Breast degenerative disease (35%):
Common in middle-aged and elderly people, due to changes in hormones, degenerative changes in the glands and ducts of the breast, abnormal catheter development, poor mammary gland structure, resulting in epithelial hyperplasia, proliferation of cells and secretions to form tumors.
Infection (20%):
Clinical statistics show that patients with anaerobic infection or areola infection have a much higher rate of breast ductal tumor than those without the above two infections. Pathological analysis shows that the inflammatory response stimulates epithelial cell proliferation and accumulation of lipid secretions, induced The disease.
Other factors (15%):
The disease is also associated with nipple retraction or deformity, squamous epithelium extending into the inner wall of the catheter causing occlusion of keratinized scaly, or autoimmune disease.
Prevention
Breast ductal cancer prevention
1. Regular review. Because breast ductal tumors have the possibility of malignant transformation, it is possible to control the condition at the appropriate time in the hospital. In general, the patient is usually reviewed every three months. Of course, you can also do some simple checks yourself.
2, mental emotions. The occurrence of breast ductal tumors is closely related to mental emotions. Therefore, female friends should maintain a good mood and be vital to stay away from the disease.
3, diet adjustment. The so-called disease from the mouth, a lot of illness is caused by personal bad habits. Patients should be light, eat more fruits and vegetables, avoid spicy food.
Complication
Breast ductal complication Complications
According to statistics, women with breast ductal tumors have a malignant rate of 5% to 10% more than normal people. Breast ductal tumors are one of the predisposing factors for breast cancer and are called "precancerous lesions". highly valued. Therefore, once diagnosed, you should go to a regular hospital for examination and treatment.
Symptom
Breast duct tumor symptoms Common symptoms Breast lumps areola deep and lumps nipple discharge
1, single large intraductal papilloma can be in the areola or the edge of the areola can reach a cord-like mass about 1cm long, or the nodules of the sputum and jujube nucleus, due to the accumulation of blood in the catheter When the mass is pressed, there is a blood sample, milk sample or coffee-like secretion overflowing from the nipple, but the overflow port is fixed. The disease is often intermittent spontaneous discharge, or extrusion, collision and collision. Most patients found a brown stain on their underwear and found it. The discharge of the discharge, the tumor becomes smaller, the pain is not obvious, and occasionally there are tenderness, dull pain and other symptoms of breast ductal tumor, which is rare.
2, multiple middle and small intraductal papilloma originated from the non-tip catheter, located in the peripheral area, due to the proliferation of glandular epithelium in the middle and small ducts. There are many nodules in the upper quadrant of the affected side, the beads are beaded, the boundary is unclear, the texture is uneven, some of them have the symptoms of breast ductal tumor with discharge, and some have no discharge, the blood is bloody, yellow water Sample, coffee. The malignant transformation of this disease can reach 5 to 10%, which is called "precancerous lesion" and must be highly valued.
Examine
Breast duct tumor examination
1. Physical examination, pay attention to the location, size, boundary, shape, texture and mobility of the mass, whether it adheres to the skin or chest wall, whether there is tenderness, whether the skin has depression or edema (orange peel sign) and satellite stove, and compare. The bilateral axilla and supraclavicular lymph nodes were swollen, pay attention to their number, hardness, mobility, and compare.
2, check the nipple for secretions, pay attention to its nature, and send cytology examination. A biopsy is performed at the fester. Fine needle aspiration cytology is feasible for suspicious masses, but negative results cannot rule out cancer.
3, auxiliary examination, breast dry film, mammography, mammography, mammography, oral examination, such as infrared heat display, liquid crystal thermography, ultrasound, etc., to assist in diagnosis, if necessary For liver B-ultrasound, lung and bone X-ray or (and) radionuclide scanning, CT, MRI, to determine whether there is distant metastasis.
Diagnosis
Diagnosis and diagnosis of breast ductal tumor
diagnosis
Diagnosis can be performed based on clinical performance and laboratory tests.
Differential diagnosis
Note that the disease is differentiated from intraductal papillary carcinoma and ductal dilatation syndrome.
1, catheter dilatation syndrome: often accompanied by congenital nipple depression, the discharge is mostly bilateral porous, traits can be watery, milky, serous, pus or blood; papilloma and ductal dilatation syndrome The edema of the areola can be seen in the period, but the lumps of the latter are often larger than the former, and the shape of the lumps is irregular, the texture is hard and tough, and it can adhere to the skin, often causing redness and swelling, and can be broken and pus in the later stage.
2, papillary carcinoma: the discharge is more common in bloody, and mostly single-sided single hole. The mass of papilloma is mostly located in the areola area, the texture is soft, the mass is generally no more than 1cm, and the ipsilateral axillary lymph nodes are not swollen; while the papillary carcinoma is mostly located outside the areola area, the texture is hard, the surface is not smooth, and the activity is poor. Easy to adhere to the skin, the mass is generally greater than 1cm, and the enlarged lymph nodes can be seen in the ipsilateral armpit.
