Abstract: Objective To study the correlation between X-ray signs and lymph node metastasis of breast cancer.Methods 62 cases of breast cancer who were pathologically confirmed were retrospectively analysed.We observed their molybdenum target image signs by the following 5 indicators for analysis:(1)form of the lesions,(2)whether there was burr at the edge of the lesions,(3)whether there was calcification within the lesions or nearby,(4)size of the lesions,(5)lesions position.Data were analyzed using SPSS version 15.χ² test was used for enumeration data,and P＜0.05 was considered as statistically significant.Results In the 62 cases of breast cancer,lesion size was greater than or equal to 2cm,and burr at the edge of the lesion were statistically correlated with lymph node metastasis(P＜0.05).Whether the lesion is a mass,or there is calcification within the lesion or lesions position showed no statistical significance(P＞0.05).Conclusion Lymph node metastasis often occur in breast cancer patients with mammography imaging signs of the lesion size greater than or equal to 2cm and burr at the edge of lesion,which are reliable signs for clinical diagnosis of lymph node metastasis.Whether the lesion is a mass or there is calcification within the lesion of lesions position have no significant correlation with lymph node metastasis in patients with breast cancer.
