The significance of the three-dimensional hook wire of molybdenum target in guiding the excision of calcification lesion of the breastis studied. And its clinical role in terms of improving early diagnosis of hard-to-detect breast tumor and locating the accurate resection of the lesion is highly anticipated.

32 cases with negative clinical examination and different forms of calcification founded by X-ray molybdenum target between January 2015—June 2016 in our hospital were collected. These patients immediately received the resection of the lesion after the three-dimensional wire hook line of molybdenum target positioning, followed by the X-ray take to determine the lesion has completely been removed. The specimens were sent for pathological examination to decide the following operation method.

In all of the 32 cases, malignant lesions were detected in 11 cases including:ductal carcinoma in situ 6 cases, infiltrating ductal carcinoma 3 cases, invasive lobular carcinoma 2 cases; benign lesions in 21 cases: hyperplasia of mammary glands with calcification 16 cases, fibroadenoma with calcification 3 cases, dysplasia 2 cases. It is found that the distance between the hook wire and lesions <2 cm, brings out the best positioning.

Molybdenum target three dimension hook wire of localization can significantly improve the diagnosis of early breast cancer, provide guidance for surgical resection of lesions, reduce unnecessary cut of normal breast tissues and improve the life quality of patients.
