Nipple discharge is a common symptom of breast disease and can be divided into physiological discharge and pathological discharge. Physiological discharge refers to the lactation during pregnancy and lactation, bilateral nipple discharge caused by oral contraceptives or sedatives, and a small amount of unilateral or bilateral discharge in postmenopausal women. Pathological discharge refers to natural discharges from one or more catheters on one or more sides of the body that are not associated with gestational lactation in non-physiological conditions. Intermittent, persistent, nipple discharge from months to years is mainly referred to as Pathological discharge.
Nipple discharge according to its physical properties can be divided into: blood, serum, serous, water, purulent, milky and so on.
Breast cancer patients have 5-10% nipple discharge, but nipple discharge is only 1% of the only symptoms. Discharge is often single-tube, and the properties can be varied, such as bloody, serous, watery, or colorless. Patients with primary breast cancer who have primary ductular or morphological intraductal carcinomas are more likely to have nipple discharge, such as intraductal papilloma malignant transformation, papillary eczema-like carcinoma, etc., all of which can have nipple discharge. It is worth noting that although most people think that breast cancer is seldom associated with nipple discharge, and even if the discharge appears to occur almost immediately after or appearing as a tumor, those who do not have a tumor are rarely considered as cancer.
However, recent studies have shown that nipple discharge is an early clinical manifestation of certain breast cancers, especially intraductal cancer, and can exist alone before a significant mass is formed.
Intraductal papilloma is a disease with more nipple discharge, accounting for the first place in all nipple discharge lesions. Among them, intraductal papilloma of the areola area is more common and can be single or multiple, with age ranging from 18 to 80. Do not wait, the more common 30-50 years old. Tumor diameter 0.3-3.0cm, average 1.0cm, more than 3.0cm often malignant. Discharge properties are mostly bloody or serous, others are rare. It is generally believed that papillary tumors that occur in large ducts are mostly single and rarely cancerous, whereas those with small and medium ducts are often multiple and visible cancerous. Both are the same type of lesions, but only the site of occurrence, the growth process is different.
Although cystic hyperplasia is not a tumor, the most common benign lesions of the breast tissue are more common in the 40-year-old and rarely seen after menopause. Among them, cysts, ductal hyperplasia, papillomatosis three pathological changes is the basis for its discharge. Most of the nature of the slurry, the disease combined only 5% of the discharge.
Although not all nipple discharges are symptoms of breast cancer, if you have a nipple discharge, you should go to a professional hospital as soon as possible to do relevant checks to actively prevent the occurrence of cancer.
