1、 At present, China accounts for female breast cancer incidence rate of incidence of the first. 发病率高 On womens physical and mind damage the most. 身心损伤大 Diagnosis and treatment more difficult.诊断及治疗较困难 1. Differentiation of low breast cancer:分化分化低的乳腺癌低的乳腺癌1) hardware carcinoma硬癌2) medullary carcinoma髓样

2、癌3) diffuse carcinoma (also known as inflammatory cancer)弥漫性癌(亦称炎性癌) 4) mucinous carcinoma (also known as colloid carcinoma) 粘液癌(亦称胶样癌) 2. Highly differentiated breast cancer:分化高的乳腺癌 1) adenocarcinoma腺癌2) ductal carcinoma (also known as tube cancer)导管癌(亦称管内癌) 3)papillary carcinoma (also known as pap

7、 enhance Most malignant lesions showed clearance-type廓清型enhanced Platform-type平台型can be benign lesions, but also for malignant lesions. Level 0: assessed评估is not complete, to further assess the need for other imaging Level 1: no abnormal findings无异常发现 Level 2: Benign found良性发现- routine follow-up Lev
