乳腺导管内原位癌(ductal carcinoma in situ,DCIS)是局限于乳腺导管系统内恶性上皮细胞的异常增生,通常起源于一个导管束,常位于近乳头的导管内,亦可发生在远离乳头的小导管内。因尚未侵及基底膜和周围乳腺间质,故通常不进入局部脉管系统和淋巴道而发生转移,属癌前病变,但具有发展为浸润癌的潜能,及早发现其治愈率极高~([1])。因此,作为早期发现和/或诊断乳腺癌等乳腺相关疾病 Ductal ductal carcinoma in situ (DCIS) is an abnormal proliferation of malignant epithelial cells confined to the ductal system of the mammary gland. It usually originates from a bundle of catheters, often located in the duct near the nipple, and can also occur distal to the nipple Small catheter. Because it has not yet infiltrated the basement membrane and the surrounding breast stroma, it usually does not enter the local vasculature and lymph node metastasis, a precancerous lesion, but has the potential to develop into invasive carcinoma, early detection of its high cure rate ~ ( [1]). Therefore, as an early detection and / or diagnosis of breast-related diseases such as breast cancer
