Abstract
Objective To observe the early onset breast cancer（EOBC） sonographic performance characteristics and explore the diagnostic value of ultrasonography in EOBC. Methods 60 cases EOBC patients younger than 35 years old were seclected as the observation group. Older than 35 years of 50 patients with breast cancer were seclected as the control group. Two groups were underwent breast color Doppler ultrasound. Results 59 cases in 60 patients with preoperative ultrasound diagnosis of breast cancer, one case was misdiagnosed as mastitis pseudotumor infiltrating ductal carcinoma, lobular carcinoma, ductal carcinoma in ultrasound showed more direct signs, medullary carcinoma showed more indirect signs. Clumps were main types of breast cancer of the observation group and control group, respectively, accounted for 72.9 % and 87.5 %, the difference was statistically significant （ X2 = 6. 293, P 〈 0.05 ）. Two groups of color Doppler richness, lesion shape, boundary definition, without hyperechoic halo, calcification and glitches levy or levy Crab compared were not significant（ P 〉 0.05 ） ;Compared with the control group, heterogeneous internal echo, rear attenuation of observation group had significant differences （ P 〈 0.05 ）. Foci were observed group EOBC anteroposterior diameter and aspect ratio were significantly lower than that of the control group, the difference was statistically significant（t = 6. 720,9. 285, all P 〈 0.05 ） ; diameter was significantly higher （ t = 34. 962, P 〈 0. 05）. Conclusion Early-onset breast cancer at diagnosis with color Doppler ultrasound large diameter aspect ratio is small, and the rear common heterogeneous internal echo attenuation less characteristic features, screening younger women for breast cancer is important.
