乳腺癌如何分类 郭向阳 山西省肿瘤医院
乳腺癌的分类：1、根据病理显微镜下形态学上癌细胞是否突破乳腺导管或腺泡基底膜侵入间质，分为浸润性癌和非浸润性癌。非浸润性癌又分为导管原位癌和小叶原位癌；浸润性癌又分为浸润性导管癌，占所有乳腺癌分类的75%；浸润性小叶癌，占所有乳腺癌分类的5%到15%，还有一些比较少见的乳腺癌，如粘液癌、小管癌、髓样癌、大汗腺癌、神经内分泌癌，化生性癌等。2、根据发病年龄分为妊娠哺乳期乳腺癌、年轻乳腺癌和老年性乳腺癌。3、根据是否绝经分为绝经前乳腺癌、绝经后乳腺癌；4、根据分子生物学类型，分为雌激素受体阳性型乳腺癌、三阳性型乳腺癌、her-2阳性型乳腺癌和三阴性型乳腺癌；5、根据疾病进展程度分为炎性乳腺癌、早期乳腺癌和晚期乳腺癌。

How to classify breast cancer
Classification of breast cancer: 1. According to the pathological microscope, whether the cancer cells break through the breast duct or the basement membrane of the acinus and invade the stroma, It can be divided into invasive cancer and non invasive cancer. Non invasive carcinoma can be divided into ductal carcinoma in situ and lobular carcinoma in situ; Invasive carcinoma is divided into invasive ductal carcinoma, 75% of all breast cancer classifications; Invasive lobular carcinoma, 5% to 15% of all breast cancer classifications, There are some rare breast cancers, For example, mucinous carcinoma, tubular carcinoma, medullary carcinoma, apocrine adenocarcinoma, neuroendocrine carcinoma, Metaplastic cancer, etc. 2. According to the age of onset, breast cancer can be divided into gestational breast cancer, young breast cancer and old breast cancer. 3. According to whether menopause is divided into premenopausal breast cancer, postmenopausal breast cancer; 4. According to the type of molecular biology, It can be divided into estrogen receptor positive breast cancer, three positive breast cancer, HER-2 positive breast cancer and three negative breast cancer; 5、 According to the degree of disease progression, it can be divided into inflammatory breast cancer, early breast cancer and advanced breast cancer.
